Traditional roofing products such as Torch-on, SBS, EPDM, and PVC all have one vital flaw: they are not truly seamless. Even though the individual sheets of these products are heat welded or glued together, they ultimately are not a one-piece installation. Natural expansion and contraction caused by temperature fluctuations and freeze/thaw cycles expand small voids or gaps in seams weakening them and potentially opening them right up over time. Polyurea has much higher tensile strength and elasticity (400-900% elongation), meaning it holds up to repeated movement extremely well. During application, each pass of polyurea sprayed is chemically bonded to the last pass, meaning there are no seams at all, even where the roof meets upturns and parapet walls.
Often there are areas of an existing roof that just don’t drain as well as they should. When water is left pooling on the surface, it can accelerate wear at the seams as mentioned above. Some materials also have less than ideal water permeability ratings, meaning that over time water will seep into the roofing substrate if it is left sitting in one place for too long. Polyurea, on the other hand, is widely used as the waterproofing membrane in swimming pools, landscaped ponds, and large public aquariums, so you can rest assured knowing no water will be seeping through your roof.
Penetrating structures and flashing
Any time a roofing product is applied around an interruption such as a pipe, HVAC unit, vent stack, access hatch, etc. an opportunity for leaks is introduced. Traditional materials all rely on layering separate pieces of the coating up the object and gluing or melting them together. Since polyurea is extremely flexible and is sprayed right up any upturns in one seamless application, there are no seams that can be pulled at or separated over time.
Damage from falling objects or roof access, natural expansion and contraction, wind and water erosion, the sun’s ultraviolet radiation, and many other things are all damaging your roof coating over time. Our polyurea roof systems provide optimal protection against all of these influences and outlast virtually all other roof coating systems on the market today.
Poor workmanship on repair jobs or repairs using mismatched or poor-quality materials don’t fix leaks on a roof, they just make for bigger leaks later. Some roofing products by their nature are just hard to properly repair in the first place, which results in vulnerable sections of your roof. A section of a polyurea roof can be properly prepared and sprayed again if any new roof structures are added or modifications are made, resulting in a truly seamless integration with the rest of the polyurea roof.
