"I was very impressed with Gary and his team at Legacy Construction. He was very professional and responsive to my questions and provided knowledgeable answers. He also provided before and after pics and videos of the work in the roofs (main and sunroom) and the gutter system replacement and always kept me informed of their progress. In fact, I plan to use them again for additional home projects!"

"I have used Union Roofing for over 40 years and will continue to do so as the need arises. The owner told me, after calling them on Sat., that they would be out the first thing Mon. morning and that they were. I rely on their punctuality and superior workmanship."

"First,, I received a very prompt response to my inquiry for service. Carlos then came out and gave me an extremely through overview of the entire project, not missing even the slightest detail. Every step was explained and every scenario which might incur additional expense was mentioned so there wouldn't be any surprises. As a result, the estimate was spot-on. The crew was courteous and professional throughout the job, which was completed start to finish in one day. I couldn't be more happy with the service and flexibility provided by Carlos and Shirley. I highly recommend their roofing services to anyone looking for the highest quality and value for their money."

"Joe Fisher ,the owner, called the day we put in the search for roofing help. He was very personable and friendly. He talked a great deal about himself ,family and his roofing experience so we hired him. I was a little disappointed we never received the formal typed contract. He related stories his assets were frozen and he brought another hand written paper? The roof appears to be fine so far and the flashing is holding up. His methods are a little shaky so I don't know about the warranty but so far so good!"

"I was so happy with Stephenson roofing! They were incredibly easy to work with, professional, and reasonably priced. I had my full roof replaced (a flat roof on a row home) and it looks great. I will definitely be reaching out for any future work."
