"They did a magnificent job of installation and the clean-up was perfect. They removed the old roof quickly, made sure the roof boards were in good shape and put the new roof on in a little over 1 day. They were careful around my plants. We even were able to get some money back for bad shingles that were used on our old roof and the best part was they did all the paperwork!! When they came over to bid the job they were very professional, had a folder with all the information put together with different roofs in the area we could look at before we made our final decision. I highly recommend them to anyone looking for a new roof!!
