A 55-Square HOA Duplex Roof Done the Right Way

This Stratham, NH roof replacement was for a side-by-side duplex in an HOA — about 55 squares total — and it needed a lot more than just new shingles. With a shared roof, getting it right matters for both units and the association as a whole.

What We Found When We Got on the Roof

Once we were up there, the underlying issues were clear. The fascia had started to break down in spots, sections of the roof deck were compromised, and the ventilation setup wasn't doing the roof any favors long-term. These are the kinds of problems that quietly shorten a roof's life if a contractor just shingles over them.

What We Did

Full tear-off across both sides of the duplex
Replaced the damaged sections of roof decking
Repaired the fascia where it had deteriorated
Improved the ventilation so the roof can breathe and perform as designed
Installed Owens Corning TruDefinition® Duration® shingles in Onyx Black

How It Turned Out

Both units now share one clean, consistent roof system that's built to last — not just look good from the street. The ventilation is working properly, the weak spots are gone, and both halves of the duplex are protected going forward.

Why This Matters for HOA and Shared Properties in Stratham

With HOA properties and duplexes, you can't afford to "just get by." If one side fails, it quickly becomes everyone's problem. A lot of the roofs we replace around Stratham have the same hidden issues — ventilation shortcuts, overlooked wood rot, edge details that weren't done right. Fixing those during the replacement is the difference between a roof that struggles in a few years and one that delivers its full expected service life.

If you manage or own a shared property and you're thinking about a roof replacement in Stratham, make sure the contractor is looking past the shingles. That's where most of the real problems start. Get a free estimate or call 603-219-1523.

Stratham Asphalt Shingle Roofing — FAQs

How big was this HOA duplex roof?

About 55 squares total across the side-by-side duplex — a full tear-off and replacement on both units so the shared roof is one consistent, modern system.

What extra work goes into an HOA or duplex roof replacement?

Beyond new shingles, this job included replacing damaged roof decking, repairing deteriorated fascia, and correcting the ventilation. On shared properties those repairs are critical, because if one side fails it becomes the whole association's problem.

Why is ventilation so important on a roof replacement?

Proper attic ventilation lets the roof breathe, which helps it reach its full expected service life and reduces moisture and ice-dam problems. Ventilation shortcuts are one of the most common hidden issues we find on Stratham roofs.
