"Roofmaxx put a coating on my roof which warranties to extend the life of the roofs shingles for 5 years. In addition, they checked over shingles repaired needed areas on the roof, and did caulking around skylights and chimney. They worked quickly and were very professional. They quickly finished the project of spraying the roof. So far everything looks good. I have already recommended them to my friends. They also quoted me a price, that they said was good for one year, and a year later they kept their promise. Which I see as a good sign of the dependability of RoofMaxx."
