Metal
Once the anodized protective coating weathers off of a metal roof, it is prone to oxidation. The oxidation process will cause rust in metal roofing systems. This rust will eventually eat holes right through the metal if not protected again with a waterproof roof coating…
Acrylic and Emulsion
Emulsion and Acrylic roof coatings systems became popular in the 1970s as a way to prolong the life of traditional roofing materials. Over time commercial style flat roofing systems tend to develop areas of ponding water. This ponding water then permeates through the reflective acrylic roof coating…
Concrete
As a concrete roof ages, it will lose its pH balance. Once the pH in concrete falls below 10, it begins to deteriorate. By rejuvenating a concrete roof with integral crystalline technology prior to a membrane encapsulation, you can prolong the service life of a concrete roof for an additional 50 years or more…
SPF (Foam)
Spray Polyurethane Foam (SPF) is used as a roofing system on buildings where energy consumption is important like a cold storage or large climate controlled facility such as hospitals or film storage. The SPF foam must be protected or it will absorb moisture, expand, break open and rot…
Silicone Coatings
Silicone roof coatings are used as a maintenance reflective coating over flat and low-sloped roofing systems in various climates. Silicone is known for its chemical resistance but not so much for its UV stability. UV exposure to silicone roof coatings often causes discoloration, blistering and deterioration…
Hypalon
Hypalon is a trademark for chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM), a product of DuPont Performance Elastomers. Hypalon is a single-ply roofing material with similar performance and weathering of PVC or TPO single-ply roofing…
EPDM (Rubber)
EPDM is a durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) used for flat and low-sloped roofs. EPDM rubber roofs are manufactured in rolls and adhered to the roof with fasteners and a liquid adhesive or tape to seal seams…
Gravel
Gravel roofs are composed of several built-up layers of roofing felt, sealed with asphalt or coal-tar. Because the asphalt is not UV resistant, these roofs are covered with a layer of gravel for protection. Gravel roof systems are one of the hardest roof systems to chase and locate leaks in…
TPO (Thermoplastic polyolefin)
TPO is a single-ply roofing material that is installed similarly to PVC with mechanical fasteners and heat welded seams. The existing TPO roof has miles of seams and special flashings. TPO is a polymer/filler blend that typically consist of a thermoplastic, an elastomer and a filler…
PVC (Polyvinyl chloride)
In the manufacturing of PVC roof membranes, plasticizers are added to the PVC to increase the flexibility of the plastic and increase elasticity. Plasticizers are additives meant to lower the cold-flex temperatures and increase the durability to PVC. Over time these plasticizers evaporate or migrate out of the plastic…
Modified Bitumens
Modified Bitumens were developed to increase the weatherability of roofing asphalts. Modifiers were added to replace the plasticizers and enhance flexibility characteristics. Modified roof membranes can be smooth or granulated for added UV resistance…
Built-up (BUR)
Built-up roofs (BUR) are made up of plies of saturated or coated felts adhered together with asphalt. These felt sheets are topped with a cap sheet or a flood coat of asphalt or coal tar pitch. Sealing seams in this type of traditional roofing material is commonly part of roof maintenance as the asphalt eventually cracks open under exposure to heat and UV radiation…
