Established in 1976, All Under One Roof has the experience and expertise to get the job done right the first time. Our skilled professionals use only the finest tools and materials for your residential or commercial project. We guarantee our work and your satisfaction.

"Overall it went great. John was down quickly after I first contacted him. He came out in person to give me information and confirm the online measurements. Between meeting him, reading the reviews online, and the impeccable warranty I felt very comfortable choosing him (the price was in the middle of the other quotes I got). The whole process took 3 real long days. Obviously it is loud and disruptive while they are working... but you only need a new roof once. I would suggest not parking in your driveway as there are a lot of people and trucks. At the end they cleaned up very nicely. They are a legit roofing company so they pull permits. Overall I am quite please for the job, cost, time etc."

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."

"We started out dealing with one of the sales reps John Fossetti. Great experience. He told us about the company, about the products, had samples and a huge selection of siding to choose from. He was very open and answered all of our questions. After several consultations with many companies we knew Beantown was for us. We scheduled siding replacement for our entire house as well as new window replacement for all windows - 24 of them and a new slider. They were very professional and their crew was excellent. The windows had all new construction around them and we got ProVia windows that carry a lifetime warranty. They removed all of the old siding, fixed any rotten or damaged areas, wrapped the entire house to waterproof it and hung new siding, trim, gutters and gutter guards. It turned out absolutely beautiful. Our house looks new again! Jim Ewell the project manager was great to work with. He was very supportive, professional and answered all of our questions. Both he and John were a pleasure to work with. Also, their office staff were very helpful as well. Beantown went above and beyond for us and were so reasonably priced. I highly recommend them!

FAQs for roof sealant application projects in Hamilton, MA

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
