Roofing Contractor in Half Moon Bay, CA

Salt air, fog and fasteners on the Coastside

Ocean air carries salt inland, and on the coast it settles on every exposed metal part of a roof. Combined with near-daily summer fog, that moisture and salt shorten the life of components that last much longer over the hill.

Half Moon Bay incorporated in 1959, but its roofs range far wider than that date: older wood-frame houses and storefronts around Main Street, post-war homes on the flat coastal terrace, and newer subdivisions built under Coastal Zone rules. What they share is weather. The coast stays cool most of the year, so roofs rarely dry out between foggy mornings, and algae streaks and moss show up on slopes that would stay clean over the hill. Exposed fasteners rust from the head down, and drip edge corrodes first where it was cut. Then the winter storms arrive straight off the ocean between November and March, and every weakened part gets tested at once.

Wind-driven rain and storm damage over Highway 92

Winter storms reach the coast first and hardest. Rain driven sideways by onshore wind gets past flashing details that stay dry in calmer towns, especially at sidewalls, skylights and around chimneys. Gusts peel shingles from ridges and lift loose metal edges. After a storm we tarp what we safely can, photograph damage for your insurer, and help you document the claim. Our storm damage roof repair page describes the process in more detail.

Coastal Zone permits and how a visit works

1. We set a Coastside day, typically a week or more out, and confirm Highway 92 conditions before driving over.
2. The estimator checks fasteners, flashing and vents closely, with photos of corrosion and wear.
3. Your written estimate specifies corrosion-resistant materials for each item.
4. Building permits come from the City of Half Moon Bay. The city lies in California's Coastal Zone, so ask its Planning staff whether your project needs a coastal development permit before anything is scheduled.
5. Crews clean up daily and keep debris from blowing in the wind.

Highway 1, Main Street and the unincorporated Coastside

Half Moon Bay counted 11,795 residents at the 2020 Census. We arrive over State Route 92, which meets Highway 1 on the edge of town, and most addresses sit a short drive either way along the coast highway or off Main Street downtown. Half Moon Bay State Beach runs along the shoreline west of town, and Pillar Point Harbor and the county-owned Half Moon Bay Airport lie a few miles north near Princeton and El Granada.

• City or county: El Granada, Princeton, Miramar, Moss Beach and Montara are unincorporated; the County's Planning and Building Department issues their permits and handles their coastal development review.
• Fire service: the Coastside Fire Protection District, staffed under contract by CAL FIRE, covers the city and its unincorporated neighbors.
• Water: the Coastside County Water District supplies Half Moon Bay and El Granada.
