How do I hire a roofer for a coastal home in Pacifica or Half Moon Bay?

What does the ocean do to a coastal roof?

On the coast, salt spray and steady onshore wind attack the metal on a roof first: nails, drip edge, valley and step flashing, vent caps and gutters. Shingles in constant damp also grow algae and moss on shaded slopes. InterNACHI's life-expectancy figures assume ordinary conditions (InterNACHI); near the water, plan on metal parts wearing out sooner. Ask bidders exactly which metals they'll use and whether the product warranty has coastal conditions.

How do I check a Pacifica or Half Moon Bay roofer's license?

Search the business on the CSLB license lookup. For a reroof you want an active license with the C-39 Roofing classification (CSLB: C-39), a bond on file and, if the company has employees, a workers' compensation policy. The name on your estimate should match the CSLB record exactly.

City or county permit?

• Pacifica: City of Pacifica Planning & Building
• Half Moon Bay: City of Half Moon Bay
• Montara, Moss Beach, El Granada and other coastside communities: unincorporated, through San Mateo County

The roofer should confirm which applies to your parcel before quoting. The whole coast is in climate zone 3 (CEC), so a cool roof isn't required.

What should I ask a coastal roofer?

• Will you use stainless or coated fasteners and heavier flashing?
• Is the shingle installed to the high-wind specification, and is that in writing?
• How will you seal vents and skylights against wind-driven rain?
• Can you schedule around winter storms? See El Niño and your roof.
• What maintenance should I plan for the gutters and metal?
