Galaxy Builders Roofing exceeded every expectation. From start to finish, the experience was smooth, professional, and stress-free. Mike Rooff (yes, that’s really his name—and yes, he’s the real deal) was fantastic to work with. He was knowledgeable, responsive, and took the time to clearly explain the process, options, and timeline. No pressure, no fluff, just honest guidance and solid expertise. The crew showed up when they said they would, worked efficiently, and delivered top-quality results. The workmanship was excellent, the job site was kept clean, and the final product looks great. If you’re looking for a roofing company you can trust, I highly recommend Galaxy Builders Roofing and Mike Rooff. Professional, reliable, and exactly who you want protecting your home.
Galaxy Builders, Inc. did a fantastic job replacing my shingles roof! From start to finish, the process was efficient and as painless as possible. The crew was in and out within a day. Love my new roof!
Mike stepped in to finish a project we had started with a previous contractor who refused to complete the job (enclosing our patio and building a wet bar). We hoped Mike would just get it done for us, but he made suggestions at almost every stage that elevated the entire thing. We are so happy with how it turned out. Mike and his team are incredible to work with. Really thoughtful and accountable for their work they do. Great communication, prompt responses. Everything a contractor should be and more. Can't recommend Galaxy builders more highly.
Galaxy Builders replaced the old, damaged vinyl siding on our home recently. Their crew installed durable, long lasting James Hardie board and batten, and finished with a coat of Sherwin Williams Emerald acrylic latex exterior paint & primer. This is an upgrade that should last us for years and years. Thank you, Galaxy Builders! :)
I have know Mike with Galaxy Builders for quite a few years so he was my first and only call when my roof started leaking under our old pool solar panels. He came out quickly and provided a quote to remove the old solar panels and old roofing materials. The job was scheduled quickly and completed in one day. My yard was thoroughly cleaned and the only evidence of them being there is my new roof! Thank you Galaxy Builders!
