Leave us a review
After heavy rains, my commercial building in San Bernardino would get 3" of standing water sitting on the flat roof with no place else to go, but through the roofing material and inside the business...not good. Erich and his crew took care of that by creating a pitch on the roof to prevent any standing water from accumulating. They did a very nice job, and it works.
Barbara P.Google Review
Professional, responsive, honest. Erich is a delight to work with! This is a large condominium complex and there was considerable work in simply evaluating the roofs on 189 units. He explained the roofing terms and the work needed. We want to use him for all our future roofing repairs and replacements.
Sheryl C.Google Review
They took care of the small roofing job in a quick and professional manner. We were very happy with the final product. Thanks for putting us in touch. Tom French and Linda Sutherland
