There is a reason Gallagher Bros only warranties their workmanship for five years—it seems they know their work won’t hold up much longer than that. We had our roof replaced by Gallagher Bros in 2019 after a hail storm. When the job was completed, we immediately noticed several issues with the workmanship. We contacted the company, and while they sent someone back out, only some of the problems were addressed.

We have used Gallagher Bros 2 times (new roof and storm damage) and have had a great experience both times. They were able to help us navigate major storm damage and get what we needed taken care of. We worked with Willie each time and he’s been super helpful. Highly suggest working with them!

We had a great experience with Gallagher getting our roof, gutters, and siding replaced after hail two years ago. A year and a half later, our roof started leaking in the fall. I called a handful of times trying to get someone out to fix it and nothing ever happened. A woman on the phone said they wouldn’t come out if it was too cold or snowing. I gave up for the winter. Now that’s its spring, the leak is worse and we have problems with a clogging gutter and broken siding. I’ve been calling for two weeks and still, no one ha... read more
