What is polymer roofing?
It’s almost like paint. That’s what this type of roof coating is. It’s a roof coating, not actually roofing. If you put the coating on a roof you are trusting the integrity of the roof you already have.
We’d suggest just getting a new roof instead of coating. If we do a job where the customer wants coating and will not change their mind, we will do it but we will insist tell the customer that the integrity of the roof cannot be trusted down the line.
