Why Choose Gateway Roofing

Built by Builders, Not Just Roofers

Gateway doesn’t just install shingles. As a full-service construction company, we assess your roof’s structure, ventilation, and drainage — not just the surface. That means problems get caught early, not after they’ve caused damage inside your home.

Fixed-Price Quotes, No Surprises

You’ll get a clear, written estimate before work begins. No add-ons, no “we found something else” charges. The price we quote is the price you pay.

Workmanship Warranty on Every Roof

Every roofing project is backed by our workmanship warranty, on top of manufacturer material warranties. If something isn’t right, we’ll make it right.

4.9★ Google Rating Across 60+ Reviews

Testimonials

Gateway Group did an amazing job replacing the shingles on my roof. The quality of work was so good, even my home inspector gave it his stamp of approval! Highly recommend them if you want it done right the first time.

Cory and the Gateway team helped me out greatly when I was in a big pickle at one of my rental properties! I needed the roof repaired and I needed it fast. They were easy to communicate with and they helped me get all the roof problems solved as well as some other odd jobs! Highly recommend and will be using their services for my own home when it’s needed in the next few years.

I needed an outdoor patio roof replaced. The original owner had cut every corner possible and we had leaks and a broken skylight pane! Cory from Gateway Group was great. He came by quickly to review the issue and provided an honest and fair quote. He and his team arrived the day they promised to arrive and got the work done on time and cleanly. Thank you, team. I know who my first call will be next time I need work done in my own home.
