Had roof and gutter system including facia and soffit replaced. Thanks to the crews that had to deal with the terrible heat to complete the tasks. Also thanks to Scot Hollrah for his expertise in answering my questions and managing the project to completion.

Great experience and workmanship. Highly recommend. Curtis was great to work with. Besides giving my grandma a bid on the roof and gutters, he got a bid for the ceiling damage inside and worked with her insurance company to get it all approved.

The experience was great! From the salesman (Scot) to the roofers. They did an amazing job. Left it so so clean. Thank you so much.

You’re in good hands with Gallagher Bros. Their crews are professional, they keep your yard clean, and their workmanship is top notch. Rex is the man! I knew things would be done right and if there were any issues, Rex would get it taken care of right away.

We used Gallagher Bros for roofing replacement in the past. When it came time to replace our cedar siding we knew we could work with Gallagher Bros Construction. They advocated for us with our insurance company and had the expertise to install LP composite siding rather than vinyl. Bob, Chris, and Carlos were wonderful to work with and always very responsive. They were detail-oriented and several of our neighbors have commented on the high quality of work. We couldn’t be happier with the results.
