I had gotten a few estimates and theirs was the best. I was worried that it might not be as good, but it turned out even better than my next door neighbor’s roof. They even climbed up to the roof to take a look at the workmanship and said it was done very well. One of my other neighbor had his done by David also because of the friendly staff and David the owner was there to supervise the work not just to show up for the payment!!! They cleaned up after themselves and even cleaned up the neighbor’s yard so that we wouldn’t get in trouble for the mess. Definitely recommend them to fix your roof without any worries and no need to chaperone them when they do the work. Worry free, when you give them your roof to renew beautifully!!

I looked for a roofing contractor for over a year. 6 quotes and the prices were all over the place for the same job! Then I found David General Contractors. The quote was excellent and the ONLY QUOTE professionally presented with samples!!!! More importantly David was a pleasure to deal with! He approached the few problems we found with a smile and said "Don't worry I'll take care of it." and did! He fulfilled our contract and more! I can't say enough good things about DGC! I would highly recommend David and his wonderful crew. Look at my beautiful GAF Timberline Biscayne Blue roof with a solar roof vent and two new skylights and call him!
