"We love that we can safely collect drinkable water..."

I purchased GAF's HydroStop system with GAF WOB Top Coat from you for The Nature Conservancy at Ballast Key back in February. Out on Ballast Key we collect all of the rainwater from our main house and use it for potability after getting filtered through a filtration system. We love that we can safely collect drinkable water from the roof and gutters of our buildings because of the Hydrostop System. We really liked how simple and easy it was to install the GAF system and will use it again! Thank you,

"This is the best and prettiest top coating that I have ever seen."

I am an Engineer and have been using many products for many years. This is the best and prettiest top coating that I have ever seen. Oakley, a salesperson at hydrostop supply, is rated a 5+++. Very familiar with the complete product line, true in all his statements about the products and delivery. If their is a problem with the product, delivery, etc. he will correct it with one (1) phone call on the same day. He is quick to understand, polite, knowledgeable, all around superior in his job - "top-of-the-ladder".

Long Lasting Protection

We live in Texas. My commercial building has metal roof and the flat parts are covered with the Hydro Stop System. I got to tell you, this is good material ( Hydro Stop ), our building is about 14-year-old, and the Hydro Stop is still holding.
