Gallagher Bros killed it! I was jumping through hoops to find a company to come do a residential shingle job in St. Charles, and Curtis got it done! Kinda dumb how hard it is to find good roofing people, but they were crazy fast for a fair price. Super nice guy and team to work with
After our roof was damaged in the tornado that came through St. Louis on May 16, 2025. I talked to a couple roofing companies before choosing Gallagher roofing. Curtis at Gallagher Made us feel like a high priority …brought in a great team and did the job all in one day with an exceptional cleanup at the end! I was super paranoid about nails being left In the driveway after a previous experience with another roofing company, but I didn’t find anything like that with Gallagher. Thanks for a job well done, and I will use them again in the future.
Fantastic experience with Gallagher Bros. The owners Jake and Curtis are stand up guys and will go the extra mile to make sure the job gets done right. Would highly recommend.
This past fall was especially stressful with all the weather damage. Gallagher took a lot of that stress away. Prompt, honest, great quality and a fair price. They helped us through the process with their knowledge and attention. I spoke with Curtis a number of times and really appreciated his straightforward approach. It’s exciting to hear they opened an O’Fallon office. I now consider Gallagher my roofing partner.
I cannot speak highly enough about Gallagher Bros. They did a fantastic job with my roof. The team was very professional and a pleasure to work with. They did a great job helping me work with the insurance process. The roof itself was installed quickly and well done. I highly recommend choosing Gallagher Bros. for your next project!
