Worked with Willie, had them do a new roof, siding, gutters, and trim. The house looks great, and we are very happy the whole process.

I had Gallagher do a roof inspection, install gutter apron around house, fix flashing on chimney and reanchor fake shutter around all my windows. Samuel and Kenny were both very knowledgeable and went above and beyond. Would highly recommend.

I'm extremely satisfied with Gallagher Bros for the removal and installation of vinyl siding, soffit, fascia, gutters, windows. Rex was fantastic to work with from beginning to end. The workmanship of all the crews, even clean up, plus customer service was TOPS! I would strongly recommend them to anyone needing this type of work. YMR

I highly recommend Gallagher Bros Construction. They replaced my roof, did the siding of my house, and replaced my gutters. You can count on them not only to get the job done, but to go above and beyond your expectations as they did for me. They are also fast paced and professional. Rex is absolutely delightful. He is quick to respond to calls/texts. He is willing to come out to your place and check on his employees work too. If something is not finished, he will make sure that it gets done. - Alia H.

Gallagher Bro Construction replaced our flat roof at our rental property. The project manager Jeremy Mills and their crew did an incredible job! They are hard-working, diligent professional, honest, and just the best quality that you can ask for from the company. Jeremy answered all the questions I had even during his vacation time. You can see how responsible and reliable they are. Jeremy is excellent in communication and easy to work with. Roof replacement is not easy to process. They kept the promise to finish the project on time! They made it easy for me. Their bid was very reasonable.
