HOA Roof Replacement in Stratham, NH – 55 Square Duplex with Repairs & Ventilation Fixes

Project Overview

This roof replacement in Stratham, NH was for a side-by-side duplex in an HOA—about 55 squares total—and it needed more than just new shingles. When we got up on the roof, it was pretty clear there were some underlying issues. The fascia had started to break down in spots, parts of the roof deck were compromised, and the ventilation setup wasn’t doing the roof any favors long-term.

We handled this one the right way, start to finish: Full tear-off across both sides of the duplex, replaced damaged sections of roof decking, repaired fascia where it had deteriorated, improved the ventilation to help the roof perform the way it should, and installed Owens Corning TruDefinition Duration shingles in Onyx Black. Now the entire duplex has a clean, consistent roof system that’s actually built to last—not just look good from the street. The ventilation is working properly, the weak spots are gone, and both units are protected moving forward. With HOA properties and duplexes, you can’t afford to just get by. If one side fails, it becomes everyone’s problem. A lot of roofs we replace around Stratham, NH have similar issues—ventilation shortcuts, overlooked wood rot, edge details that weren’t done right. Fixing those during the replacement is what separates a 5-year roof from a 25+ year roof.
