Longmont roofs take repeated hail strikes during summer thunderstorms that roll across Boulder County. Older asphalt shingles in Old Town and Kensington often show granule loss and cracked tabs after even moderate hail, while newer laminated shingles in Sunset can hide fractures until water finds the felt. Left Hand Creek drainage patterns mean runoff concentrates along north-facing slopes, so missed hail punctures quickly turn into attic leaks during the first snowy winter. We map impact zones by walking the entire surface and checking soft spots with a probe rather than relying on satellite photos.
Underlayment tears from hail are common on homes built before 1990 in Downtown Longmont, where original 15-pound felt has dried out. We replace damaged sections with synthetic underlayment that meets current Boulder County wind-uplift requirements instead of patching over the old layer. Metal flashings around chimneys and skylights dent easily and lose their seal; we reshape or swap these pieces before re-sealing because hail-weakened metal will leak again once temperatures swing from warm summer days to freezing nights. Every repair is photographed and documented for insurance adjusters who visit properties near Roosevelt Park and the Longmont Museum.
Edge cases include hail that skips over ridge caps yet fractures field shingles on the windward side of homes facing open fields west of Sunset. We test these areas by lifting tabs gently rather than walking the whole roof again. When granule loss reaches the mat on more than thirty percent of a slope, we recommend full slope replacement instead of spot repairs to avoid mismatched weathering that stands out from the street. Loveland crews sometimes send overflow calls our way after larger regional storms, confirming the same hail patterns cross county lines.
Technician insight
In Longmont the thing that catches most people out with Hail Damage Roof Repair is how quickly hail fractures the brittle shingles on 1970s and 1980s homes in Old Town and Kensington; those roofs look fine from the street until the first heavy snow melts into the attic because the underlayment was already punctured.
Hail Damage After July Storm in Sunset
A homeowner in Sunset noticed granules collecting in the gutters after a July hail event. We found cracked tabs on the south slope and two underlayment punctures near a skylight. We replaced the damaged shingles and underlayment section, resealed the skylight curb, and documented everything for the insurance adjuster. The roof stayed dry through the following winter.
