Gallagher Bros Construction

Gallagher installed a roof for me on Father's Day 2024 to replace one originally installed just a few years prior. Another Roofing company gave me an estimate and found all kinds of problems with the way my roof was originally installed which caused inside ceiling damage from the flashing around the fireplace being improperly installed. I went with them again as they promised to guarantee (since I was just months shy of the warranty) that they would take good care of me. The roofers did not put down anything, even a tarp to protect any items in my yard. My pool cover, canopy, outdoor sectional, were heavily damaged. Even my cushions and pillows were covered with tar. They left nails everywhere. My gutters were full and even months later I had nails that transferred to my gutters/downspouts and wound up all throughout my yard and driveway. I had three flat tires at three different times. (See attached pictures). Last month, in March after the storm my ceiling began sagging and having the same issues. It had only been 8 months, so I called Gallagher to report the issue. I learned that Mike the original guy I worked with was no longer with the company. They told me I would have to wait 4 weeks out for someone to just come look at it. The first weekend, I waited all Saturday for my appt, and never heard a word, so I waited All Sunday. They never showed. After several calls and texts they rescheduled me 2 weeks later, and then once again, never showed up on the Saturday of my appt. I again thought perhaps they would come Sunday when my calls and text went unanswered. I then waited an entire week with no response. When I called the office rather than apologizing Mary was very condescending insinuating that they were too busy to deal with me, even though it had been 6 weeks and they never even showed up one time to look at my roof. When Willie finally called me he told me he would try to "fit me in" again but to make sure I had my insurance information ready to sign over. I told him my roof was only 7months old and that I just wanted an estimate and my inside ceiling looked at and he told me that is not the way they "worked". They do not give estimates. They base their charges on what the insurance pays. I told him this damage should be covered by them and it is just not right and was "shady". I also told him their customers deserved a call if they were not going to show up as 2 weekends were spent waiting for them. Not wanting to even run the lawn mower thinking I might miss them. He told me that they would no longer wanted to work with me. No apologies for never showing up, no apologies on my roof once again leaking...I was upset/shocked I called back to the office to share what transpired and Brittany answered the phone. I told it had been 6 weeks since I originally reached out to get an estimate, and she interrupted me and very derogatory said "last time you called you said it was 4 weeks get your story straight", she immediately told me they did not want to work with me. OF COURSE they don't want to work with me, they have put 3 roofs on for me, and every one has had issues and has leaked. This is a terrible company to deal with. The only decent person there was "Mike" and he has moved to Florida. I would be very leery of the way they base their prices and try to get more money from the insurance companies. And we wonder why our insurance rates are going up with these types of practices. The office women are extremely rude and condescending. It has been a terrible experience, and I cannot believe the owner of this company would allow his office personnel to treat his customers in this way. If I could give "0" stars I would. I will be looking into any legal recourse I may have. There are many roofing companies out there, Gallagher should not act like they are doing you a huge favor to just show up when they should or do the work properly.

Gallagher Bros. did all the repairs to the exterior of my home after the March 2025 hail storm in Oakville. Brett was great to work with. He was thorough and the bid they gave us was very reasonable. They worked with our insurance company throughout the process and all the work was completed to our satisfaction. Highly recommend them if you need any work done to your home. They were great!

Gallagher Bros were great to deal with. They did a great job on my siding and roof install and knocked it out quickly. Brett was very helpful and transparent while helping me navigate through my insurance and scope of work needed to get the job done. I would recommend them to anyone looking for a quality install.

Excellent experience from start to finish! Our rep, Patrick White, along with the rest of the team were professional, on time with everything, and delivered high-quality work. Communication was excellent. Anytime we called or sent a text, we got a timely response. My husband and I are very happy with the results and would definitely recommend Gallagher to anyone needing construction services.

I am extremely satisfied with the work that was recently done on my home. I had a new roof installed, gutters and downspouts, and some fascia replaced. The crews did nice work and were very friendly. Brett came out several times after various storms to give me advice on my roof. He also spent a lot of time going over the ins and outs of the claim process and really helped me to understand how it all works. Definitely a five-star review for Gallagher Bros and my highest recommendation.

We are very pleased with Gallagher Bros. Service, from beginning to end. Brett did a wonderful job of explaining what our insurance covered, and what services Gallagher Bros. Would provide. The work was done well. I highly recommend this company.

⸻ Gallagher Construction recently replaced my roof, and I couldn’t be happier with the results. The workmanship was top-notch, and Patrick was incredibly helpful and supportive throughout the entire process. The office staff was just as great—always polite, professional, and patient with all of my questions. Even with the high demand following the March tornado, I never felt like just another job. They took their time, paid attention to detail, and never cut corners. Highly recommend Gallagher Construction if you’re looking for quality work and outstanding customer service!
