I am very happy with the quality of work done by Grennan Construction on my roof replacement! The crew did a great job, and I'm very picky. I got on my roof to inspect it after they were done and did not see any issues that needed to be addressed! THANKS FOR A GREAT JOB!!!

Probably one of the best experiences with a contractor ever. Price was competitive, detailed and transparent. Guys were very professional, quality installation, attention to detail. A lot of little extras that they didn't nickel and dime us for without complaint. Of particular note, the color we picked for our gutter downspouts didn't look the same as the sample. We brought it to their attention to see what could be done about it. They agreed it didn't match and came out and replaced it with another color immediately without any hesitation or pushback at no cost to us. Now that's how you take care
