I have used this company and would encourage anyone looking for an honest and ethical company to use, call SunTech Roofing. They have helped on a couple of minor issues on the roof and then with the severe storms they replaced my entire roof. The quote was given and work began on time- the workers ripped off the entire old roof (they did not simply add to the old roof) and replaced it with new. After the job was complete, they cleaned up everything. Best roofing company in Knoxville!!!
