Types of Flat Roof Repair
If you have a flat roof, chances are, you're going to need to repair or replace it sooner or later. By design alone, a flat roof is prone to collecting idle water until it evaporates, giving it more time to find weak spots and enter the structure. So what are your options if your flat roof needs repair?
Spray Applied Coating
Spray applied coatings are a great option for a flat roof. There are 3 main options for flat roofs: Silicone, Acrylic, and Aluminum. These are all applied in liquid form, and allowed to cure once in place.

If your installation team isn't well versed with this type of installation, you could certainly be facing fire damage or worse. But, if you are working with an experienced installation team, your new Modified Bitumen flat roof installation will be a quick and simple one that will help your structure reflect heat with an extended lifespan.
