What a complete pleasure working with Rex at Gallagher Brothers. The quality and craftsmanship of the roofers was excellent. Many bid the job, but Gallagher Brothers were the best option by far. Two up 👍🏻👍🏻

I had a great experience with Gallagher Bros construction. They replaced my roof and it really looks amazing. After they replaced it they went through my yard and picked up all the waste. I highly recommend them to everyone.

We went with Gallagher to get our roof and gutter replaced. Our contractor, Jeremy was very thorough, helpful, responsive and honest! Getting a roof replaced can be a very stressful process but they made it smooth and stress free. Highly recommend them!
