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 ๐Ÿ‘๐Ÿป๐Ÿ‘๐Ÿป

I highly recommend Gallagher Bros Construction and Brett Keenan for any roofing and gutter needs. Brett and team are pure professionals and made sure everything was done right from start to finish. They made the insurance process a breeze and explained everything thoroughly and answered my all questions. We are very happy with a job well done!

Worked with Brett, and got my roof replaced as well as my gutters and down spouts, and did an excellent job. Brett was great and communicated with me the entire process. I would highly recommend using Gallagher Bros and working with Brett! Thanks!

I just had a new roof installed by Gallagher Bros. Construction and am very happy with the entire process. Rex worked with me from start to finish and definitely had my best interest in mind throughout. He was instrumental in dealing with my insurance company and claim process. The installation crew did a great job in a timely manner. Everyone at Gallagher was very courteous and professional. I highly recommend Gallagher Bros. Construction and am truly appreciative of Rex's efforts.

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!
