Herman and his men were very professional. They found two separate leaks from a 9 year old roof that the original contractors refused to stand behind. They are well known contractors here in town. Herman did much investigating and found underlayment to be improperly applied. Herman even came here in the rain to determine the problem and cover the roof temporarily with a tarp. He is extremely thorough, determined , hard working, and clean. His price also was most reasonable . Would highly recommend him and he gives a 3 year warranty.
