Flat & Low-Slope Roofing work in New Hampshire, in practice

New Hampshire roofs take a specific kind of beating. In this region, ice dams at the eaves are the classic failure mode — meltwater backs up under the shingles and shows up as a ceiling stain two rooms away. That shapes what we find on inspection more than anything else: damage concentrated at the details — flashings, penetrations, valleys, ridges and the perimeter — rather than evenly across the field of the roof.

nor’easters bring sideways rain that drives into flashing joints and dormer walls On top of that, dozens of freeze-thaw cycles each winter work nails loose, open seams and crack old flashing

summer heat is milder, but UV still dries out and curls 3-tab shingles by the 18-year mark.

The housing stock matters too. Across New Hampshire, most stock was built either side of the middle of the last century, and a lot of it has had at least one re-roof already. Roofs on that stock tend to age in clusters, which is why a single storm event can produce years of concentrated roofing work in one neighbourhood and none two streets over.

Why flat roofing is not a one-size job here

Flat and low-slope roofs cover porches, additions, garages, dormers, commercial buildings and modern residential designs. Because they shed water slowly, they depend on continuous membrane, correctly lapped seams, sealed terminations and drains or scuppers that actually flow.

We install and repair TPO, EPDM, modified bitumen and self-adhered systems, and we take drainage seriously — ponding water is the single most common cause of premature failure on a low-slope roof.

What flat roofing costs in New Hampshire

Low-slope work is quoted by area and system. As a national guide, single-ply membrane replacement with insulation typically runs roughly $7 to $16 per square foot installed; repairs are quoted per occurrence and coatings by area, usually meaningfully cheaper than replacement where the membrane is still serviceable.

Insurance note for New Hampshire: Ice dam damage is often covered as a sudden event, but long-term seepage from neglected maintenance usually is not. Photographs of the ice build-up and the interior damage help establish when it happened. We will tell you honestly whether what we see looks claimable before you open a claim — and we do not charge for that assessment.

Material guidance for this climate

The two details that matter more than shingle brand here are ice-and-water shield along the eaves and valleys, and correct attic insulation and ventilation to stop ice dams forming in the first place. Architectural shingles outperform 3-tab on every metric.
