Roof Replacement in Londonderry, NH with Full Re-Decking, Spray Foam Prep & Black Sable Shingles

Project Overview

This roof replacement in Londonderry, NH was a little more involved than most—but it's a great example of doing things the right way from the start. The homeowner planned to spray foam the underside of the roof deck, which meant the existing decking had to be completely removed to allow proper application. Once we opened everything up, we prepped the structure and got it ready for a clean, high-performance install.

We completed a full tear-off down to the framing, installed brand new roof decking after spray foam prep, shingled with Owens Corning TruDefinition Duration Designer shingles in Black Sable, added metal accents on the dormers for a clean high-end finish, and installed proper underlayment and waterproofing throughout. The result is a fully rebuilt roofing system that is tight, efficient, and ready for spray foam insulation, built to handle New Hampshire weather, and finished with a sharp architectural look thanks to the Black Sable shingles and metal details. For homes in Londonderry, NH, projects like this show that roofing isn't always just a shingle swap. When insulation, ventilation, or structural components come into play, the install needs to be done with a full-system approach—or problems show up later.
