Silicone Restoration Membrane roofing system material is the perfect material to use for old single ply roofing systems. There are roofing contractors out there that will convince homeowners to pay for a new roof restoration system using low cost (and lesser quality) acrylic elastomeric coating on a roof with a Single Ply roofing system. Over a period of time acrylics begin to thin out due to weather and general environmental conditions. When this happens, and it will, the homeowner is trapped by the contractor because the roof will wear thin and need a reapplication at some point down the road. The homeowner will have to pay for roof maintenance / roof restoration over and over.
Single ply roofs can also be restored by installing another single ply roofing system layer to the existing roof. The issue with going this route is that the system being installed is the same as the existing roofing system that failed, which makes zero sense. For business owners installing a Single Ply roofing system over an existing one is looked at from a tax standpoint as building capital improvement, which in most cases is only deductible as a business expense over several years, as opposed to a Silicone Restoration Membrane, which most of the time can be deducted that year. The second issue with installing a single ply roofing system again is that it is viewed as second roofing system. The very negative aspect about this method is that when the roof fails a new seamless coating will have to be installed (only 2 roofing systems by building code are allowed to be installed) or a high cost roof tear off and replacement will have to be done. Either option means the single ply roof system installation today will mean a new expensive roof restoration or roof replacement down the road.
The very best option is to go with a Silicone Restoration Membrane roofing system. The pluses about this method are extensive. It is the fastest to install, it costs the least and it normally lasts the longest. The product is very stable and it requires very little maintenance, making it the best choice when it comes to roof restoration versus installing another single ply roof system or doing a tear off and roof replacement.
Single Ply Systems By Definition:
- TPO Single Ply: Thermoplastic Polyolefin single-ply roofing. This roofing material can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems. This is a popular choice for “Green” building as there are usually no plasticizers added and TPO does not degrade under UV radiation. It is available in white, grey, and black. Using white roof material helps reduce the “heat island effect” and solar heat gain in the building.
- Hypalon Single Ply: Hypalon is a trademark for chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) noted for its resistance to chemicals, temperature extremes, and ultraviolet light. It was a product of DuPont Performance Elastomers, a subsidiary of DuPont.
- Along with PVC, CSM is one of the most common materials used to make inflatable boats and folding kayaks. It is also used in roofing materials, and as a surface coat material on radomes, owing to its radar-transparent quality.
- Hypalon is also used in the construction of the decking of modern snowshoes, replacing neoprene, as a lighter, stronger alternative.
- Hypalon has become the common name for all kinds of CSM, even though DuPont was not the only manufacturer.
- EPDM Single Ply: Ethylene propylene diene monomer is a synthetic rubber most commonly used in single-ply roofing because it is readily available and relatively simple to apply. Typically, there are three installation methods. Ballasted at 1,000 lbs/sq or 10 lbs/sq.ft. with large round stones. Mechanically attached is another method and is suitable in some applications where wind velocities are not usually high. Fully adhered is the most expensive installation method.
- PVC Single Ply: Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. Vinyl is derived from two simple ingredients: fossil fuel and salt. Petroleum or natural gas is processed to make ethylene, and salt is subjected to electrolysis to separate out the natural element chlorine. Ethylene and chlorine are combined to produce ethylene dichloride (EDC), which is further processed into a gas called vinyl chloride monomer (VCM). Thermoplastic are heat-welded seams and form a permanent, watertight bond that is stronger than the membrane itself. PVC resin is modified with plasticizers and UV stabilizers, and reinforced with fiberglass non-woven mats or polyester woven scrims, for use as a flexible roofing membrane.
