What the weather does to roofs in Seward

Across the 1991-2020 climate normals, Seward averages summer highs averaging 85°F, 28 in of precipitation a year, and 21 in of snow — the loads a replacement here is bought to survive.

The dominant stressor is deep winter cold. Seward’s average winter lows of 14°F sits lower than all but 6% of the 1,037 cities covered here. Winter lows averaging 14°F matter for scheduling more than for product choice. Asphalt shingles will not seal below roughly 40°F, so a Seward roof finished late in the season can sit unbonded until spring. Ask whether the crew hand-seals, and when they plan to start.

147 days a year dropping to freezing compounds it — in the 90th percentile among the same set. 147 crossings of 32°F a year work moisture into every nail hole and flashing lap, then expand it. Sealant-dependent repairs are the first thing to go, which is why flashing in Seward is better replaced than re-caulked when a roof is opened up.

The self-adhering membrane at the eave is what stops ice-dam water getting in. Code measures its depth from the exterior wall line, not the fascia — on a deep overhang that means a second course.

Does this guide cover areas near Seward?
