Improper Nailing Technique Linked to Recurring Roof Leaks in NH Homes

Paramount Roofing found improperly nailed shingles causing a New Hampshire home's roof leaks and replaced the system with a standing seam metal roof.

BELMONT , NH, UNITED STATES, August 28, 2026 /EINPresswire.com/ -- New Hampshire homeowners dealing with a roof that keeps leaking or shedding shingles despite repeated repairs may be facing a problem that goes deeper than the shingles themselves. According to Paramount Roofing, a Hooksett based roofing contractor, one of the most common causes of recurring shingle failure is a nailing error that isn't visible until the old roofing material is removed.

The issue came to light during a recent job in Belmont, New Hampshire, where a homeowner called Paramount Roofing after noticing an active leak along with a noticeable amount of shingles sliding out of place. The roof had already been repaired multiple times by other contractors, but the sliding kept coming back.

Once Paramount Roofing's crew removed the existing shingles, the cause became clear. The prior installation had nailed the shingles directly into the tongue and groove plywood decking rather than into proper structural framing, and the nails were only catching about a quarter of an inch of material. That shallow nail hold was not enough to keep the shingles secured, which explains why the sliding kept returning no matter how many times the roof was patched.

"When we see the same problem come back again and again on a roof, it usually means the real cause was never actually fixed," said Brandon Sullivan, owner of Paramount Roofing. "This is a mistake we see more often than people realize, and it's worth knowing about if your roof keeps having the same issue no matter how many times it gets repaired."

Rather than repeat the same repair, Paramount Roofing installed a new layer of plywood over the existing insulation to create a properly fastened base, then installed a standing seam metal roof using metal clips, a method that does not rely on face nailing through the panels.

Paramount Roofing encourages any homeowner experiencing repeated shingle problems, sliding, or leaks in the same area of their roof to have the deck and fastening method inspected before authorizing another repair.

Paramount Roofing serves homeowners throughout the Lakes Region and central New Hampshire, including Belmont, Tilton, Franklin, Gilford, and Boscawen, offering roof replacement, roof repair, and standing seam metal roofing in addition to asphalt shingle systems.
