Rex was a pleasure to work with and the roof they put on my house in December of 2021 looks great . . . so why not 5 stars? #1: Well, they never called me to tell me they were coming to my house at 7am on December 18th when my 2 children were sleeping upstairs. Woke up the house. #2: They put on 5 inch flashing on my stucco dormers (that I am sure meets code but they never told me they had to do this.) So Rex gets an A+ and quality of work gets an A but communication with actual roofers = C.)

The roofing crew was very professional, arrived on time and did high quality work.. they completed the job in one day and still cleaned up after themselves. Two days later another guy came out with a magnet to make sure there were no nails or any other debris in the yard. They also did a great job replacing hail damaged siding. I highly recommend Gallagher Bros. Construction.

I couldn't have been happier with the service and professionalism from Gallagher Bros. In particular a shout out to Willi, from the start he walked me through the process and was very thorough and made me at ease with the entire thing. We had other companies come out to provide quotes and by far went with Gallagher because of our first interaction with Willi. I also dealt with Caesar, Chris & Garrett and Mary in the office. Again everyone that I spoke to was nothing less than professional. The roof looks fantastic and I would highly recommend this company.

We needed a new roof and also needed a repair done to the garage roof/gutter where a tree limb had fallen on it many years ago. We got 3 bids, and Gallagher was in the middle of the other 2 for the roof, and gave a very reasonable bid for the repair work, which one of the other companies was not able to bid, as they did roof work only and not construction. We went with Gallagher and are thrilled with the result. The repair is flawless, you can’t even tell it was previously damaged, and the roof looks great, and they left everything clean when they finished. Willie was awesome to work with. He explained everything thoroughly when he came out to bid, was very responsive to questions we had when we were making our decision, and made sure everything was to our satisfaction when the work was complete. I highly recommend them!

From start to finish these guys are as professional as they come. This was my first time having to replace my roof, and my contract manager Rex came out three separate times despite AllState hiring an adjuster who no-showed twice. Not once did Rex get upset with me for his time being wasted. Rex checked out my roof for damage to help me fight my insurance company to make sure I didn't come out of pocket. Once the AllState adjuster deemed I had to replace my roof, I was quoted a 2-3 week timeline to allow for shipping materials and availability for the Gallagher Bros. roofing crew to open up. They actually replaced my roof the next week so I didn't even have to wait the full three weeks. The warranty process on my roof was easy and Rex laid everything out for me, was flexible with my work schedule the whole time. Highly recommend because they were transparent throughout the entire process, explained everything they did step by step to help me get a grip on my first process, and was extremely professional even though their time was clearly wasted twice. Their work is great quality and absolutely worth it. Pictures attached of the Storm Grey.

From start to finish, highly recommend these guys. My parents used them first, then referred us to them and we were highly pleased throughout the entire process. Rex and everyone else we dealt with was honest, up front and easy to work with. He fought for us to get our insurance to pay the claim on our roof, walked us though every step and went over every detail so we knew what to expect, so there were no surprises. The company is local, easy to reach and used all over StL- just a great, local, honest contractor. I can't say enough positive things about our experience with them, and rest assured they will be our first contact for future needs. If you want an easy to work with, reliable, honest and quality company, give them a call.

While I think the work that they actually did is good, communication and follow up is frustrating, especially if there is something the crew didn't get to during installation. I've called and spoken to both Willie and a person in their office several times and I'm still waiting to get someone to come out to reinstall the gutter guards that were on the gutters prior to the estimate.I've been told someone will come out for the past three weeks and no one has. When I called them today they said that the work might have been done and I just didn't know they were there. I can see the gutters and trash that was left in them. They said they'd call back today and never did. I was told there would be a walk around inspection after work was complete and that didn't happen either.I won't recommend this company due to the shear frustration of trying to complete the job that has been fully paid for.Edit - Thank you for your response, Jared. The work has been completed and I appreciate that. I commend your crew for working as hard as they did and doing a great job on installation. It was the lack of communication between the office and project manager that was frustrating for me.

I had spoke witg an employee of Gallagher Bros that was doing some work in my area. Interested in having somebody come give me a quote. I had spoke to Garett who was only interested in having me agree to have him do the job and pay him cash directly. Then was very rude when he finally accepted no as my answer and then offered no further help. Very dishonest and very unprofessional

I had Willie come out and bid my new roof. He was on time and very professional. I had another local roofer scheduled to also give me a bid and they failed to even show up.Gallagher scheduled my install pretty quick once the supplies were delivered. They were there early on the day of install and stayed until the job was finished. They cleaned up before they left and you would have never known they were even there. The quality of service appears to be very good.

They were definitely easy to work with and did a good job that deserved 5 stars.

I had Willie come out to give me a second opinion on a third party roof job (not done by Gallagher) after the third party had left my yard a mess, damaged my gutters in 3 places, and a representative from John Beal said the roof job I had done was terrible. Afraid John Beal was just trying to rope in a sale, I asked Willie to come out, and his exact words were "as much as I'd love to get the sale, they did a beautiful job with your roof." He assured me that the multiple things John Beal told me was wrong with the roof I had put on, were in fact perfectly fine or even better than he's seen done in the past. I'm sad I did not use Gallagher to begin with, but will definitely recommend them to all of my friends and family. His honesty and reassurance was exactly what I was looking for, and of course validated that the Beal rep had lied to me.

Responded to a door hanger offering a free inspection and written report.They sent a highly qualified and experienced roofing expert who, after about an hour +/-, indicated he saw sufficient evidence that we should submit a claim to our homeowner's insurance company. He provided us specific instructions and asked that he be present when the insurance company made their inspection. Within just a few days, the insurance company's claims adjuster showed up to meet at our home with the Gallagher representative and within a couple of hours to inspect, the claims adjuster indicated they would agree to replace the entire roof and its various vents, etc. He provided us with a very detailed list of items involved together with each item's cost and then he issued a partial payment (in the thousands) on the spot to get us started. A first-class job, which took a crew one day for the main structure, was completed in a matter of days.I couldn't have asked for anything beyond what they provided and, of course, they have my highest recommendation for a residential roof replacement.

I really wanted to love this company based on their great reviews and online presence but unfortunately had a very poor experience. Things started off awesome with a very prompt and polite follow up to my online inquiry. Mary was able to schedule a technician to come out for a roof inspection within a couple of days. I'm out of state and offered to have a family member meet the inspector at the house but Mary said that wasn't necessary and that she could have the inspector call me once he was on site which is awesome because I'm currently out of state trying to manage the repair of my Grandfather's house (in the middle of a pandemic) which certainly isn't ideal.Unfortunately, the appointment day came and went, and I didn't receive a phone call. I left a message at the end of the day to inquire about what had happened and didn't receive a call back after a couple of days, so I tried calling again. I finally got through three days after the scheduled inspection and was told that Mary was on the phone but that the reason the inspector had not come out on Saturday was due to rain, which felt like a very reasonable excuse.When I asked about the possibility of rescheduling and told the woman who answered the phone that I was not local things took a very hostile turn. The woman seemed absolutely incredulous that I would even be calling her with such an ask and said that Mary was "new" and should've never told me that an inspector could come out without the homeowner present. She then went on a rant about how Mary should've been returning calls and some other inconsequential things. When I tried to stop her to offer a local relative up to meet the technician she doubled down and indicated that this would be a "waste of time" for such a small company of 10 people and we should find another company because they have had "non-payment issues" with people from out of town. And then she hung up in my face.Against better judgment, I called back to make sure she'd actually hung up and that I wasn't accidentally disconnected, and she was even more rude the second time and reiterated that my business wasn't welcome. I still haven't heard back from anyone so am assuming maybe they were burned by someone out of state but the horrendous treatment I experienced by this woman was totally uncalled for.

When our roof was damaged and needed replacing, we turned to Gallagher Brothers Construction based on their reputation and past reviews. We were contacted by Rex Anderson, Field Manager, for Gallagher Brothers and he became our single point of contact to guide us from the insurance claim process through completion of our new roof. Most important, after the Claim Adjuster submitted the final report Rex identified many errors which saved us from being shorted on our claim payment. Gallagher Brothers worked directly with our insurance company to be sure our claim was handled properly and fairly. Because of our confidence in Rex, the installers, and the friendly office staff at Gallagher Brothers we can highly recommend them.

We’ve had a deeply frustrating experience with Gallagher. We chose them because of their solid reputation for quality work and competitive pricing, and we wanted to support a local, family-owned business. The partially finished work on our home looks great, however the process has been problematic at every step. Our siding job was slated to start the first week of November and take no more than a week. It’s almost Christmas, and the job still isn’t complete.We’re totally understanding of reasonable delays and especially covid-related manufacturing slowdowns. But the communication by Gallagher’s team and subcontractors has been awful. When the first shipment of product was delivered, the truck backed over our mailbox and destroyed it. The delivery company wasn’t forthcoming at all about repairing it. It took many calls initiated on our end to finally resolve the repair, which we ultimately had to do ourselves to get a new post set in time before the ground froze. Our siding sat in our driveway for over a week with no information regarding a start date.After many calls and messages, we were told work would start the Monday after Thanksgiving. The crew didn’t show until Wednesday, and each time we had to initiate contact to get an update. Now the work is partially done and our house has sat with no progress for another week with no communication. We finally reached our contact two days ago and were told the gutter crew would be here today and the remainder of the work would be complete on Monday of next week. The gutter crew is a no show today and no one has reached out to us.I’ve never worked with a contracting company with such poor communication. We’re tired of struggling to get information, only to be given false work dates. We just want honest, forthcoming communication and the job finished.

Gallaghers was amazing to work with, especially Willie whenever I needed something Willie was there to answer my questions. We had to delay the roof installation because we had yellow jackets decide to nest on the roof. As soon as we were able to get them taken care of the crew was out the next day weather would permit. The roof has higher quality materials than the other companies I had quotes from and Gallagher's was the cheapest and easiest to work with. Thanks for making this an easy process.

Rex even came back out to our house after the derecho to check our roof. He was responsive to all of our needs. If you need a new roof, call Gallagher Bros and ask for Rex. He will take care of you!!!!

Gallagher Brothers Roofing installed new roof and gutters. From the time Willie (salesman) came to my home along with the workers on the roof crew, the gutter crew (Tim) and the work (Todd) did around the trim and skylight, work was great and attention to detail. Jared and Chris came and did a final estimate as well had Brittney come out for final walk thru and payment process, when Willie was available he also came and did a final walk thru. Very professional and well recommended. This is the crew to call if you have exterior issues. Hands down one of the best. Cost was a little higher, but you get what you pay for. Mine was not an insurance job, well worth the investment. Thanks to the Gallagher team for your professionalism and the home looks great. Respectfully.

Gallagher’s rep, Willie Wyninegar, made the entire roof and gutter installation process easier than anticipated. Willie handled each step of the process professionally, knowledgeably, and thoroughly, including the roof inspection, meeting with my insurance inspector, answering numerous questions about the quality differences of their shingle and gutter products and the accompanying warranties. During and after installation their crew cleaned up the job site very well and finished the job on schedule. We had a couple of follow up needs which were addressed satisfactorily. I’d recommend Gallagher for your roofing needs without reservation. We were very pleased to have awesome representative, Willie Wyninegar, as our Gallagher project manager.

Within a few weeks, my roof was completely renovated. Overall they made this process very easy and I would highly reccomend this company to anyone!

Gallagher Bros. Constructions recently replaced my roof due to an insurance claim. Willie made the process painless. He negotiated with my insurance company and explained all the various steps in the process. My only issue was negotiating the early summer weather that delayed my project. I was contacted the night before the crew showed up and they showed up on time. When they finished for the day, they used a leaf blower to clean up debris. They also used a magnet to sweep for any errant nails during the removal process so my dogs would be safe. My wife was surprised that they remember to protect her prized plants.
