Commercial Roofing in New Hampshire

Commercial 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 commercial is not a one-size job here

Most low-slope commercial roofs fail at the same places — drains, scuppers, penetrations, unit curbs, expansion joints and terminations — long before the membrane itself reaches end of life. That is why maintenance and detailing, rather than membrane brand, dominate the cost of ownership.

We work on TPO, EPDM, modified bitumen and metal systems, handle leak investigation on occupied buildings, and produce condition reports suitable for budgeting or a property transaction.
