Roof + Solar Bundle Companies
in Londonderry
Londonderry is a suburban town adjacent to Manchester and Derry with strong residential growth. The town's newer housing stock — many homes built since the 1980s — features the colonial and contemporary styles with well-oriented roof lines that are ideal for solar. Londonderry's apple orchard heritage means many lots have mature trees, but most residential areas still have sufficient solar access for productive systems.

Evergreen Solar
Pawtucket, Rhode Island
<p>Evergreen Solar is our <strong>Editor's Choice</strong> pick for roof+solar bundles in New England. They created this category in the region, they've refined it over four years and hundreds of projects, and their quality standards are among the highest we've evaluated.</p> <p>The 4.9 Google rating across 300+ reviews is not marketing spin — it reflects a company that consistently delivers on its promises. In a space where roof replacements and solar installations can each generate significant customer frustration individually, Evergreen has demonstrated an ability to coordinate both simultaneously while maintaining near-perfect customer satisfaction.</p> <p>Evergreen uses Qcells panels — American-made in Dalton, Georgia — paired with Enphase microinverters and CertainTeed Landmark shingles installed by a ShingleMaster PREMIER certified contractor, which reflects a commitment to quality over cost-cutting. The SureStart PLUS 5-STAR warranty (50 years non-prorated, 30-year workmanship) and 25-year solar and workmanship warranties provide strong long-term protection for New England homeowners.</p> <p>The limitations worth noting: Evergreen's NH coverage is currently limited to the southern region, and NJ is a newer market for them — VT and ME homeowners will need to look elsewhere. Demand also means their installation calendar books up. If you're flexible on timing, that's not a concern. If you need installation by a specific date, discuss timeline early in your consultation.</p>
