Gonano Treatment

Gonano Commercial Roof Treatment

Mark had a roof that was aging fast. By applying a Gonano treatment, we brought his roof back to life and saving him years before having to replace it.

Commercial flat roof treated with Gonano
The 15-year-old membrane on our workshop was beginning to lose its granules and crack. So we thought we didn't have much to lose by trying Gonano. The result is incredible. It is as if it had turned new again!
