Silicone is the material most often used for sprayed-on applications. And, because its sprayed onto the roof, it is seamless, making it work great in resisting moisture and deflecting the heat from the sun. Since it reflects the sun’s heat and rays, it lowers your utility costs, saving you money. Another big benefit is its contribution to the environment because its applied directly on top of the old system. No need for the occupants to be removed during installation and no need to tear off the old roofing and dispose of it before its applied. There are a few negatives, though – the biggest one being its price, as its more expensive than the other flat options. However, that should be expected from something of high quality with so many positives. Depending on your roof’s configuration and your location, silicone roofing will usually be the most expensive option to choose from.
