2019 NACIA AWARD WINNER

The NACIA awards program recognizes and promotes building projects in the United States and Canada for their outstanding use of architectural copper and copper alloys.

Greater Boston’s Trusted Roofing Experts

Our approach is straightforward: do the work the right way, pay attention to the details, and build roofing systems that last.

We handle everything from same-day emergency repairs and full roof replacements to complex custom copper roofing systems designed and fabricated in our own shop. We are one of the few roofing contractors in Greater Boston with true in-house copper fabrication capability — which means tighter joints, a better fit, and work that is built specifically for your home, not adapted from a standard template. No matter the project, we bring the same level of care and commitment to doing it right.

Why Homeowners & Builders Choose Paul John and Son

Same-Day Emergency Response Roof leaking? We respond the same day. Nelson and his crew understand that a roof problem cannot wait. Whether it’s a repair or a larger project, we show up when we say we will and follow through on our commitments.

10-Year Warranty on Labor AND Materials. Most roofing warranties cover the manufacturer’s materials — but not the labor. If something goes wrong after installation, you are often left arguing about who is responsible. Our warranty covers both labor and materials for 10 full years. That means if there is ever a problem with the workmanship or the materials we used, we stand behind it.

Nelson Is on Every Job Site. When you hire Paul John and Son, Nelson is there, not a crew foreman you have never met — Nelson personally oversees every project from start to finish.

Award-Winning Craftsmanship Recipients of the NACIA Award for New Construction and featured in Builder & Architect Magazine. Our work has been recognized at the highest level in the specialty roofing industry.

People Don’t Just Hire Us — They Rely On Us. Our clients come back to us not just for roofing, but for advice on all kinds of questions — because once you work with Nelson, you trust his judgment. That is the kind of relationship you can only build by showing up, doing the work right, and standing behind it every single time.

We won in the category of New Construction for the Gap Cove House in Rockport, Massachusetts. We take great pride in all of our work and it’s an honor to be recognized with such a prestigious award.
