SureCoat Roof Restoration SystemsWhy replace a flat roof with traditional roof materials that are going to wear out in a short period of time? Traditional material warranties will not cover failures in areas of ponding water. All flat roofs will pond water to some degree at some point. Roof leaks caused by ponding water occur most commonly on flat and low slope roofs. The solution is SureCoat Systems' reinforced waterproof elastomeric system for low slope and flat roofs. Avoid a costly tear-off by restoring your existing roof to Better than New condition with the SureCoat Roof System!
The SureCoat Roof System has been engineered to recondition and protect the design flaws of traditional roof materials including single ply systems. The SureCoat Roof System is not acrylic roof paint. The SureCoat Roof System is a unique, single-component, epoxy hybrid material that is liquid applied and cures into a seamless, waterproof, cool roof membrane. The SureCoat Roof System is most comparable to a single ply roof system, ONLY BETTER!
PVC, TPO, EPDM, and Hypalon single ply roofs all have common characteristics that make a flat roof vulnerable as it ages. None of these vulnerabilities exist when using The SureCoat Roof System. The SureCoat Roof System has no seams; is self-adhered; and self-flashing. Using chemistry that was originally pioneered for the marine industry, this low VOC, waterproof, epoxy hybrid, elastomeric, cool roof coating was originally developed to replace 2-part urethanes used to protect foam roofs. The SureCoat Roof is Title 24 compliant cool roof and has been used to protect flat roofs from water intrusion, heat and UV radiation long before it was popular or required.
Every property has a roof that will need attention at some time, but not every property needs a new roof. Using the existing roof and reconditioning it with the SureCoat Roof System provides a cutting edge sustainable solution to issues that plague the roofing industry, including those common to acrylic and emulsion roof systems. The SureCoat Roof System will adhere to almost any roofing material including failed acrylic and emulsion, built up, modified torch down, metal, concrete and single ply roofing systems. The SureCoat Roof System has a warranty that is renewable with maintenance applications at the end of each 10, 15 or 20 year warranty period. This is the only single-component coating system that is a complete reconditioning system with a written manufacturer’s warranty that includes coverage in areas of ponding water without limits on size, depth or time.

Standard acrylic coatings are not waterproof. The ratings listed on acrylic coatings for reflectivity and thermal emittance are based on test results done on the material at a thickness of 21-24 dry mils. This can be up to 4 gallons per 100 square feet, depending on solid content of the coating material. Unfortunately, many times an acrylic system is not applied at the correct mil thickness. When applied too thin, there is little to no protection from heat or UV. Even at the correct mil thickness, acrylics are still not waterproof! Most emulsion and acrylic roof coatings cost less than basic interior wall paint. The SureCoat Roof System is not roof paint. It is a resin heavy, waterproof, elastomeric membrane that was made to last through the harsh elements a roof endures without chipping, peeling, flaking or blistering like an emulsion acrylic roof system. SureCoat Systems’ roof coatings are the only roof coatings that are white and waterproof from surface to substrate and come standard with a manufacturer’s warranty that covers ponding on a flat roof when installed by an Approved Contractor.
We are seeing many of these types of failures within 3 years of installation. This video is an asphalt bentonite clay emulsion roof with an acrylic coating topcoat. This is what happens when water ponds on these types of roofing systems. The acrylic top coat is not waterproof so water and moisture penetrated the acrylic roof coating causing it to fail, exposing the emulsion. After time, the UV rays and heat breaks down the bentonite clay emulsion. The emulsion is the “waterproofing” in an emulsion acrylic roof system. The oils are baked out in a short period of time and the emulsion deteriorates. Once the emulsion has begun to deteriorate, leaks begin. Left unprotected the emulsion roof will lose all of its waterproofing ability in a short period of time, leaving behind a dirt roof (watch video to the right). A SureCoat Roof System is exceedingly UV stable therefore, ponding water does not affect its waterproofing ability and heat and UV has little effect on the Solar Reflective Index (SRI) of a SureCoat roof.
Thermal cycling and water, especially ponding water erode the mineral cap leaving the black sheet to absorb heat and UV radiation. Worn cap sheet cracks and checkers. The dried roof materials can no longer move so the seams separate at an accelerated rate. Exposed fiberglass mats and felt become dried out and rapidly deteriorate. The mastic around penetrations becomes brittle, splits, and leaks appear. Even brand new, these traditional roof materials on a flat roof do not have warranty coverage for leaks caused by ponding conditions. They usually have a warranty that only covers manufacturing defects, not to be confused with a performance warranty. They do not state that the rolled roofing or BUR is going to do anything in particular or wear in any certain fashion. These under-performing systems are outdated by advanced chemistry and green technology. The SureCoat Roof System is a "new age" coating material that is made from heat-emitting raw materials and nano particle infused resins. This advanced polymer chemistry creates energy efficient roof membranes that are waterproof and self-adhered, essentially shrink wrapping a roof while repelling heat and UV radiation.
The SureCoat Roof System applied over a clean, dry, and flat sound existing BUR will provide a sustainable, monolithic, cool roof membrane with a renewable warranty that covers ponding when installed according to specifications, and the warranty states how it will perform in a particular way. The SureCoat Roof System is self-flashing and self-adhered. All the penetrations and equipment curbs are incorporated into a seamless, waterproof, elastomeric system that can move with thermal cycles without becoming brittle, splitting, or cracking. By using the existing roof as a base, a SureCoat Roof becomes a sustainable roof system that never creates toxic roof material waste. Reconditioning is safe, smart, and environmentally responsible.
PVC is a single ply sheet good type roof that comes in rolls, therefore it has miles of seams like rolled cap sheet. These systems are generally anchored to the roof deck, meaning there are thousands of holes in the roof deck where the sheet material is bolted to the roof deck. As the roof thermal cycles, expands and contracts, the fasteners come loose. As the solar reflectance declines, up to 20% every three years, the PVC becomes brittle and loses the ability to move. Seam separation and stress or fracture cracks can appear. It is not surprising that one pond on an aged PVC roof can feed dozens of leaks that are extremely difficult to pinpoint.
PVC, like other single ply materials, requires special flashings at the penetrations and around equipment curbs. Seams are either heat welded or “glued down”. Some PVC used in cold climates has been known to stress-shatter, hundreds of little star-like fractures in each sheet, leaving even more opportunity for water intrusion. When PVC reaches the end of its life cycle, it has to be torn off and replaced like traditional roof materials. The old PVC ends up in landfills. PVC is made with 30% chlorine and is hazardous to the environment and people from inception until long after its service life. When PVC ends up in landfills or burns, it releases dioxins. Dioxins are carcinogenic chemicals that can leach into the water tables and are related to specific cancers such as breast cancers.
There are very few products that will adhere to PVC well enough to achieve a positive adhesion test. SureSkrub is the biodegradable cleaner that when used properly will remove the UV degraded glaze and dirt out of the existing PVC material to “etch” the surface so that the epoxy resins in The SureCoat Roof System material can bind with the PVC.
The SureCoat Roof System has stable energy-saving values. After 3 years, the solar reflectance of Sure-a-thane is 81% and thermal emittance of 93%; much higher than PVC after 3 years. This means that 93% of the heat that hits the roof surface is emitted back into the atmosphere, keeping the roof cool and lowering the heat island affect. The SureCoat Roof System material has excellent bonding abilities and transforms a hazardous PVC roof into a safe sustainable seamless, elastomeric cool roof. All SureCoat Roof Systems, when installed properly, have a renewable manufacturer’s written warranty that includes coverage for ponding water on a flat roof. Best of all, it is one less poisonous roof in our landfills.
Like PVC, TPO is a single ply material that is usually mechanically fastened with heat welded seams. The existing TPO roof has miles of seams and special flashings. Solar reflectivity decreases over time; the UV rays from the sun cause roof materials to break down and deteriorate. Several bright white TPO (and PVC) materials have a solar reflectance that is reduced by 20-30% in just the first 3 years. This makes the TPO or PVC vulnerable to excessive exposure of these rays and premature deterioration. The expected overall life cycle is decreased by this premature deterioration. Seams begin to separate and water gets under the TPO sheet and runs along the roof deck until it finds a loose fastener. Leaks appear inside at one location but the water intrusion may begin in another area of the roof. TPO systems do not have a manufacturer’s warranty covering leaks caused by ponding water.
The SureCoat Roof System reconditions TPO and adds all the missing or deficient attributes back to the roof system. The monolithic, elastomeric SureCoat Roof System will provide 81% reflectivity after 3 years; which is higher than many materials have new. The 93% thermal emittance will keep the space under the roof cooler while lowering the demand on the HVAC system and cooling costs. The SureCoat Roof is a seamless, waterproof, cool roof membrane and does not require any holes in the roof deck during installation. Self-flashing and self-adhered; The SureCoat Roof System provides the best alternative for aged or failing TPO roof systems. The SureCoat Roof System, when installed according to specifications, has a written manufacturer’s warranty that covers ponding water on a flat roof. Old roof materials are incorporated into the system by serving as a base for The SureCoat Roof System. Less non-biodegradable toxic waste goes into our landfills leaving a better environment to future generations.
SureSkrub, our biodegradable cleaner removes the glaze that has been degraded by UV rays, dirt and pollutants, and etches the surface for great adhesion. Other coatings typically do not adhere properly to TPO or other single ply materials. The SureCoat Roof System is made with high-end, epoxy resins that bond to a variety of substrates. The minimum requirement of 3 lbs per lineal inch is considered a positive adhesion result. The SureCoat Roof System has consistent test results of 13-19 lbs per lineal inch; over 6 times the minimum requirement.
EPDM roofs can be white or black. In black, these roof membranes absorb heat and do not reflect UV rays responsible for accelerated deterioration. New black EPDM has an extremely low initial solar reflectance of 6-12%; definitely not a cool roof product and like most traditional roof materials this value will lower over time. A new white EPDM starts with a solar reflectance of about 76% and after 3 years the average is 64%. The accelerated deterioration of EPDM is evidenced by the chalk like residue found on the surface. White EPDM roofs are popular on RV roofs. The deterioration can be seen after a rain; there will be white streaks down the side of the RV. Acrylic coatings are not waterproof, and do not adhere properly to EPDM. In the past, only two part epoxy systems were recommended to recondition an EPDM roof. These A and B part epoxy systems have high VOC content and cannot be used in Southern California. The materials are activated by the chemical reaction when the two parts are mixed. If they are not applied quickly, they will harden in the pail and are wasted. The Federal Government is looking to adopt a lot of the environmental policies found in Southern California which would further limit the options for existing EPDM roof membranes.
SureSkrub is the biodegradable cleaner made for use with The SureCoat Roof System. SureSkrub should be used full strength to etch the surface and remove the UV degraded EPDM and dirt from the existing roof. It is also a great cleaner for RVs and other recreational vehicles when diluted; the instructions are on the pail. SureSkrub proves that green cleaners can work well; it is the preferred cleaner of environmental agencies in Southern California.
The SureCoat Roof System will adhere to existing EPDM to create a sustainable roof system. The old EPDM can be reconditioned instead of torn off and sent to landfills. The SureCoat Roof System is a low VOC, environmentally friendly reconditioning solution for failed and deteriorated EPDM roof membranes. The epoxy resins in The SureCoat Roof System adhere to clean EPDM creating a sustainable, waterproof, seamless, elastomeric membrane that has a renewable written manufacturer’s warranty including coverage for ponding water, even on a flat roof. After 3 years, The SureCoat Roof System has a solar reflectance of 81%; testing better than brand new white or black EPDM. SureCoat roof materials reflect more UV rays for a longer period of time, slowing down the deterioration of the overall roof system. The 93% thermal emittance means that a SureCoat Roof System can lower cooling costs by emitting heat back into the atmosphere. An added benefit is that The SureCoat Roof System helps to lower the demand on the HVAC equipment and possibly extends the life of the HVAC equipment.
APP Roof (Atactic Polypropylene) is popular because it is slightly easier than other multiple ply systems and provides more slip and wear resistance than traditional composite roof materials but it has limited flexibility in extreme cold environments. It is also more dangerous to install because of the propane heating elements and open flames used during installation. As with all re-roofing projects, if there are two layers, a complete tear is necessary. Not only is this an added expense, but it is also an environmental burden when all of the old materials end up in landfills.
The SureCoat Roof System has 118% elongation at freezing temperatures making it a great choice in extremely cold climates. At 73 degrees Fahrenheit it has 398% elongation. Elastomeric roof materials should stay in this range. Without this “memory” the material will loose the ability to recover from expanding and contracting, and become brittle and crack. There are no seams to separate, no special flashings, no multiple product applications, and ponding water is covered in the renewable warranty if installed per written specifications.
APP - Modified Bitumen is not an ideal product for use as a cool roof. There is a significant difference between the initial thermal emit and reflectivity; and the gap is wider after 3 years. For example the range of solar reflectance after 3 years for Modified Bitumen is 23% to 75%. The thermal emit range at 3 years is 10 % to 99%. Of these Modified Bitumen products, the one with the thermal emit of 10% has a SRI of 64 and the one with the 99% has a SRI value of 23. The cool roof values of Modified Bitumen rapidly deteriorate. This will also lead to premature roof replacement and higher roof budgets. Also, on these APP – Modified Bitumen systems, the manufacturer’s written warranty does not cover leaks in areas where ponding exists.
The SureCoat Roof System after 3 years has 93% thermal emit, which means that 93% of the heat that hits the roof is emitted back into the atmosphere; keeping the occupied space cooler. This will lower cooling costs and the demand on the HVAC system during the summer months. After 3 years, the solar reflectance is 81%, this means that most of the sunlight and UV is reflected keeping the roof membrane from premature aging and deterioration. The SRI of The SureCoat Roof System material is 102 at 3 years, only slightly lower than the 108 it started with. The SureCoat Roof System’s manufacturer’s written renewable warranty covers ponding water without time limits, even on a flat or low-sloped roof when installed per written specifications.
The optimum solution is to use The SureCoat Roof System to recondition the existing Modified Bitumen to create a seamless cool roof that has a renewable warranty. The SureCoat Roof System provides clean, green, stable, energy-saving solutions; leaving a better planet to future generations, one roof at a time.
SBS, Styrene Butadiene Styrene, can be slightly less dangerous to install because it is usually installed using hot mopping asphalts or adhesives. Hot asphalt is the most economical way to install it but it has offensive odors and needs to be continually coated to stay Title 24 compliant. SBS systems are burdensome because of the multiple layers required to install the system. The black material on any roof holds heat and UV causing it to deteriorate rapidly. The newer self-adhered systems solve the problem of the heating aspect but fasteners are used to attach the base sheet and it is subject to wear and seam separation. This system also has unsightly black ooze that emanates from the seams. This black ooze also works against the cool roof values of a white granulated top sheet. The warranty only covers manufacturing defects of the roof material. The warranty for an installed system is not stated to perform or wear in any particular manner. A renewal option for the warranty does not exist. Tearing it off and starting over is the only way to “renew” the system.
SureCoat Roof Systems are made for flat and low slope roofs and can be used to recondition a worn out Modified Bitumen roof. The warranty is renewable and states that The SureCoat Roof System will not leak due to ordinary ponding water. You cannot buy that from a Modified Bitumen SBS or APP system manufacturer at any price.
The solar reflectance of white SBS membranes declines rapidly in the first 3 years. The initial solar reflectance values start very low. At 3 years, their value is only in the range of 25-30%. Aluminum coated SBS have better ratings than it does in white, but it is unclear how long the aluminum coating lasts. The SureCoat Roof System is a solid core of the same coating that has 81% solar reflectance after 3 years aged and dirty. Cleaning the SureCoat membrane will increase these values.
The longevity of the cool roof values of the SBS roof system is not great, but that is not the only reason this system is less than desirable. There are miles of seams that can separate with time, along with penetrations in the roof deck needed for fasteners that are required for the multi-layer installation. The SureCoat Roof System is completely seamless and absolutely no holes are made in the roof deck to install the system. The SureCoat Roof System is a solid core of energy-saving, cool roof material that lasts for the life of the system.
Spray on Polyurethane Foam is used on buildings where energy consumption is important like a cold storage or large climate controlled facility like a hospital or film storage. When these buildings are designed, the HVAC systems are engineered with the “R” value of the roofing system in mind. The “R” value means its resistance to heat. For each inch of foam on the roof, it adds a value of R-6. To remove the foam from a roof may change the HVAC system function and bigger equipment may be needed to compensate for this. The problem with foam roofs is that they need a protective coating on them continuously to keep water out and to keep the sun from deteriorating the foam into dust. An uncoated foam roof is a giant sponge that can be damaged severely from water intrusion. Not only does it promote mildew and mold growth, but it also will leave huge holes in the foam from the evaporation process. The water heats up, turns into steam and as it pushes through the foam to the surface, it creates a void. Once the vapor is released, the hole where it collected remains. Another problem is birds love to peck at it. There are a couple of theories on this. One, is they feel vibrations and think there are bugs or worms in the foam. The other is that they use it for nesting. The bottom line is birds make thousands of holes in the foam even though it may have an acrylic on it. Ceramic pigments are thought to deter birds, the evidence shows they are ineffective. There are dimples throughout the roof field creating bird baths that hold little puddles of water. Warranties for acrylic coatings do not cover ponding water, so there would be no warranty on a flat foam roof.
The best solution is to install The SureCoat Roof System over a new foam roof and never have any of these problems. SureCoat and Sure-A-Thane flat roof coatings are also the solution to existing foam roofs that pond water. The SureCoat Roof System was originally created to take the place of 2-part coatings that are recommended over foam. These coatings are expensive, take special equipment and have a short pot life and workability. The SureCoat Roof System is the best system ever made for existing foam roofs. Besides being a great first coating, SureCoat can be used to repair and recondition a damaged foam roof. The first step is preparing the roof by addressing the holes, decayed foam, and peck holes. Once the repairs are complete, The SureCoat Roof System can be installed. Depending on the desired warranty, the high solid content of The SureCoat Roof System over foam provides about 45-65 dry mils, that alone deters birds from pecking at it. The elastomeric membrane is difficult for them to penetrate and they will give up.
The SureCoat Roof System has a perm rating of .019 which is very low considering acrylics come in around 5.0 to greater than 25.0. This is the rate at which moisture passes through a surface. Ponding water over an acrylic is going to create water intrusion and all the problems that it welcomes. The seamless, waterproof, self-flashing, self-adhered SureCoat material provides the best protection from ponding water.
The SureCoat Roof System emits 93% of the heat that hits it, aiding the foam in lowering the demand on the HVAC system and cooling costs. The SureCoat Roof System reflects 81% of the sun’s UV rays that cause deterioration. This protects the delicate foam from heat and deterioration. Almost all of the initial testing values remain after 3 years as compared to other roof coatings and single ply materials that lose up to 20% or more. The single component, epoxy hybrid formula has a workability time of coatings, but bonding and binding abilities of 2-part epoxy systems. This allows adhesion to all types of surfaces including metals.
The HVAC plenums and duct work can also be coated to further lower cooling costs and extend the life of the equipment. The non-disruptive installation means the tenants can continue business as usual. The low VOC content is odorless to occupants. There are no toxic odors or fumes; the equipment on the roof does not need to be disconnected. The waterproof membrane will provide protection from the ponds that are typical on a flat roof. By forming a monolithic membrane over the roof field, there are no mastic seals around penetrations that will split or crack and allow water into the foam. Even roofs that have sustained water intrusion but have a stable roof deck can be reconditioned and protected. SureCoat Systems has solutions to address every problem encountered on a flat foam roof. Ponding water will not void the warranty. Tearing off and reinstalling a foam roof is extremely expensive. Using traditional materials would lead to inflated future roof budgets and possible additional expense to change the mechanical engineering of the facility.
Metal roofs are extruded and anodized at the factory before they are installed in the field. The baked on coatings have not provided any energy-saving benefit in the past. Most worn metal roofs have been neglected to the point that rust is evident. There will be missing fasteners that have come loose through the thermal cycling process and popped off. Beyond the surface rust, there are often holes in the metal where the roof has rusted through. Often these roofs are not attended to until there is a leak and multiple issues present.
Regular exterior paint and acrylic roof coatings cannot hold up to the constant thermal cycling, heat, UV radiation exposure and ponding water. In addition, the preparation work required to paint metal is extensive and often includes primer coats, rust inhibitors, and several top coats. All the work the contractor is required to do will not add any integrity to these paints and coatings. The oxidation process that causes rust is not stopped because water can still reach the metal as moisture vapor permeates through paints and acrylic coatings. Rust will appear from under the paint or coating proving the degradation of the metal has continued. The evidence that these materials are not made for a flat roof is the lack of a manufacturer’s warranty covering leaks due to ponding water.
In California, the contractor’s state license board requires a contractor to warranty his work for one year. Often metal roof applications, even when done correctly, will fail before a year has elapsed. The contractor has to purchase more products to do the repair and supply the labor without compensation; all because of product failure. Most manufacturers only offer a warranty for manufacturing defects, which basically means it was made right. There is no guarantee the product will do anything, like keep water from rusting the metal; from peeling off the metal; or prevent roof leaks. They simply do not have confidence in their products.
The SureCoat Roof system is a perfect fit for this type of project. The elastomeric, monolithic, waterproof, membrane adheres to all types of metals including factory coated metal, galvanized, bonderized, mild steel, sheet metal and aluminum. HVAC ducts, plenums and flashings can be sealed and reconditioned also. The SureCoat Roof System forms an elastomeric, seamless, protective, waterproof membrane over the roof field that moves with thermal cycles. Without water and air, the oxidation process is interrupted so rust no longer forms on the metal. The SureCoat Roof System is a cool roof membrane that retains most of its original values even after years in service. The SureCoat Roof system emits 93% of the heat back into the atmosphere after 3 years; keeping interior temperatures cooler. With a solar reflectance of 81% after 3 years means that the roof is protected from UV rays that cause deterioration. Cleaning the roof periodically helps maximize the solar reflectance benefits. The manufacturer’s written material warranty can be renewed with light maintenance applications every 10-15 years.
Sheet metal used to make HVAC duct work and plenums will also rust if left unprotected. HVAC duct seams, roof jacks and other metal flashings are often sealed with black and gray mastics. These mastics absorb heat, become brittle and split in a short period of time and need constant maintenance to keep the seal watertight.
The SureCoat Roof System material is an excellent product to seal metal seams and to protect sheet metal from rust. Exposed duct runs can be sealed to keep the heated or cool air from escaping through the seams. SureCoat Roof System material emits 93% of the heat which will keep cold air from heating up as it passes through the ducts in the summer for better efficiency and lower cooling costs. The lowered demand on the HVAC system may help to extend the life of the equipment.
The SureCoat Roof System has reconditioned 117,000 square feet of Hypalon roofing at the South Coast Air Quality Management District buildings in Diamond Bar, California. The roof was wearing thin and they wanted a system that did not require any holes in the roof deck. That eliminated most single ply systems on this mid rise property. They knew that black asphaltic waste by product emulsion and acrylic systems do not remain white or energy efficient as the white acrylic peels off leaving a black, heat absorbing, “waterproofing” that provides the “no leak” protection. Having a system that was environmentally friendly and sustainable was extremely important as they want to showcase green products by using them on their facility. Reconditioning meant nothing would be hauled off into landfills. Having one solar system and looking to install two more, demanded a roof that had the ability to provide protection without miles of seams or mastics that get brittle and split.
The AQMD believes green sustainability is possible by using products made to hold up under the conditions they function in daily. The Sure Coat Roof System was selected after showing them a functioning cool roof that had been in use for over 8 years at that time. That roof is now into year 11 of 20. Since that time, the maintenance application was applied and 10 more years were added to the warranty. It is renewable again in another 9 years.
The existing Hypalon roof system was prepared with SureSkrub to remove the UV degraded Hypalon and dirt before the self-flashing, seamless SureCoat Roof System was installed. The AQMD has solar systems in place and wanted a roof system that had a comparable service life. A 15-year renewable manufacturer’s warranty was issued for this project.
Tar and gravel flat or low sloped roofs are one of the most difficult roof systems to detect and repair a leak on. The gravel hides the surface of the roof and often creates a water dam on a flat roof that allows water to pond for long periods of time. When the HVAC or Satellite TV contractor walks on a dried out gravel roof, the rocks puncture the brittle roof membrane. There are usually dozens of mastic puddles throughout the roof where someone has tried to fix a leak. The problem is that walking on gravel over brittle felt or paper only increases the chances of developing another leak. Mastics absorb heat and become brittle after being in direct sunlight for 6 months. The gravel should always to be removed to properly do a repair. Once the roof is brittle and has reached the end of its life cycle, it is better to consider a full reconditioning. Otherwise, years can be spent chasing leaks. A puncture in the roof membrane from a rock can appear as a leak in another area. The SureCoat Roof System restores the roof while adding the cool roof benefits that a tar and gravel roof never had.
There are few cool roof options for gravel roofs and even less for a flat gravel roof. Usually, building a whole new and different roof system over the gravel is the only option. Foam is very expensive and one of the few viable options, but foam roofs need a protective membrane like SureCoat over them or water and UV will ruin the foam roof. Spray Polyurethane Foam roof systems are very expensive initially and to maintain.
The SureCoat Roof System is the best option for reconditioning an existing gravel roof. The SureCoat Roof System is a single component, epoxy hybrid coating system that uses the existing roof deck to add performing attributes that a gravel roof never had. There are a few steps initially to prepare a gravel roof for The SureCoat Roof System application. The full installation process is done once. After that, maintenance topcoats are added every 10-15 years to renew the warranty.
Whether on a roof or on a sidewalk, concrete is known for one thing, it cracks. Concrete is not a dense solid material, but in fact it is porous and will absorb water and other liquids, if not sealed. Water intrusion will cause the rebar or metal deck to rust and swell. Expanding rebar will cause the concrete to spall, which is thin layers of the concrete that shed on the surface. If left untreated, structural damage could affect the integrity of the building. Another roof material is often installed over a failed concrete roof, but this is always a temporary solution. A limited amount of protection is provided until that roof material fails. Leaks under failing roof materials over a concrete deck are difficult to find and repair.
The best permanent solution for an existing concrete roof is The SureCoat Roof System. The SureCoat Roof System is installed over the existing concrete deck or over the existing roof assembly without holes, fasteners or mastic seals. The renewable warranty offered by SureCoat Systems means no tear-offs and provides the last roof this property will ever need.
If the bare concrete roof is exposed, it can be treated with SS-1007. This is a low viscosity material that can be applied with a Hudson sprayer that will penetrate up to 4” to fill the capillaries of the concrete. The concrete is stronger and is no longer porous. The SS-1007 becomes an integral component of the concrete that blocks vapor emissions.
The SureCoat Roof System can be installed over the concrete roof deck or the existing roof assembly to create a permanent, monolithic, waterproof, energy-saving, elastomeric membrane that has a renewable warranty.
