Your Home. Your Priorities. Our Expertise. For more than half a century, GF Sprague has been a growing part of Boston’s architectural fabric. We began by restoring slate roofs and hand-forming copper details for some of the area’s most historic sites and city buildings. These weren’t just jobs, they were lessons in precision and pride. Slate and copper demanded true craftsmanship, the kind that can’t be rushed or faked. That craftsmanship is our foundation. As Boston grew we did too, expanding to help homeowners in the surrounding towns. We wanted to bring the same standard of excellence required on those historic projects to everyone. Today, GF Sprague adds on to our traditional roofing specialties with asphalt, rubber, and cedar. -In addition to our copperwork we can also work on chimneys, gutters, windows, and siding, Whether it’s a 100-year-old brownstone or an updated colonial home, we bring the same commitment to detail, durability, and integrity that defined us on day one. What truly sets GF Sprague apart isn’t just our skill, it’s our promise to treat every customer like family. Every roof we install is a promise: to protect a family and carry forward Boston’s tradition of homes built to last. Along with that promise is another, our Best Price Promise. This means you get the best price for your project every time. Many of our clients have trusted us for generations, passing down their loyalty just as we’ve passed down our craft. With GF Sprague, you don’t just get a contractor — you gain a lifelong, local partner in caring for your home’s exterior.

"Very impressed with Sprague, Mark was very knowledgeable and straightforward. Crew was first class closing roofing and Clean Up in four days and cold weather. Justin was terrific, personable and responsive, and was always on site or available. Crew and especially Foreman were excellent. I would recommend GF Sprague for a high quality Job, their technology and customer service."

"I had leaky roof. Of 3 contractors who came to take a look, only Ramon from NMTI pointed out an uneven surface that seemed to be good place to look for an issue. I appreciate hearing specific ideas when there’s a problem, so we chose to work with NMTI. Sure enough, underneath the shingles on that section of roof, there was some water damaged and warped plywood. The NMTI team addressed that and re-flashed some skylights at the same time. The team was all very pleasant. They scheduled the job quickly, once we agreed on details and I would work with them again. Thanks, guys!"
