"True North Contacting stepped in as the replacement for a contractor that I hired and then never showed up to do the job. They were prompt, professional and are the only reason that my project was successful. The workmanship was superior, and the detailed tile work they did came out beautiful. There are so many contractors to choose from in these times, but True North is above and beyond the rest. Look no further if you want an honest professional contractor that not only shows up, but also provides amazing workmanship at a fair price."

"The crew at James & Whitney co were extremely friendly, courteous and went out of their way to make sure that we were happy with our new roof. The job was done fast and is of wonderful quality. Beyond that, this is a company that truly stands behind their work, as they have reached out to me several times in the past few months to ask how the roof is holding up. I truly couldn’t recommend James & Whitney highly enough to anyone who needs work done on their roof."

"Capital did an outstanding job riffing my house. Roof was 20 years old and had buckled in a couple places. Needed to replace 2 plywood sheets. Material used top quality. Proj mgmt (Danny H) was great, responsive, communicated well, proactive. The roofing team was great especially in the 90f temps with dew points over 70. Hard workers, quality work. Excellent cleanup. You can find someone cheaper but not with the quality. Highly recommend."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Somersworth, NH

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
