Got an older tar roof?

Until recently, an aging hot tar roof was a huge headache. Because of the expense and liability of hot tar, most roofers won’t touch it. This has driven up the price of hot tar repair, forcing business owners to choose between two very expensive options:
Do you pay out the nose to have new hot tar applied or do you pay even more to have the tar removed completely and replaced with modern EPDM or TPO?

Finally the answer is NEITHER! 1st American Roofing is one of the few roofers in the Denver area that specializes in a silicone hot tar alternative.

The product is applied much the same way hot tar is, but without the heat. This means no open flames on your roof or a smelly tar boiler truck in your parking lot. Just like hot tar, the product can be applied to trouble spots, or can be used to recover the entire roof under certain circumstances. But unlike hot tar, our silicone alternative will most likely outlast the rest of your building. Whereas tar becomes brittle in extreme cold, our product remains elastic.

What’s better still is that our product is available in white and gray. Covering your black tar roof with our white tar alternative can reduce surface temperatures by over 30% and attic temperatures by 20%.
