Call (562) 414-1770San Pedro is part of the City of Los Angeles, set on the harbor at the southern end of the Palos Verdes Peninsula. It sits just across the water from Long Beach, about 20 minutes from our office across Terminal Island and the Vincent Thomas Bridge. The 110 ends in town at Gaffey Street.
Working here means working with wind, slopes and salt. Many homes sit on hillsides with views of the port or the ocean, and those same views mean full exposure to marine air. We pay close attention to metal parts on every San Pedro roof and choose materials that hold up near the water.
Harbor-town homes on the hillsides above the port
San Pedro has a long history as a working port town, and its housing reflects that. Older neighborhoods near downtown and the harbor have Craftsman bungalows, Spanish-style homes and small cottages from the early 1900s through the 1940s. Many have been updated over the years with shingle or tile roofs.
Post-war neighborhoods spread up the hillsides with ranch homes and split-levels, and newer homes and condos fill in the higher areas toward the coast. Flat and low-slope roofs are common on additions, garages and modern homes, and balconies and decks are everywhere to take in the views.

Roof problems we see most in San Pedro
Rusted flashing and vents
Salt air from the harbor and ocean corrodes metal flashing, nails and vent caps. Water gets in at the rusted metal long before the roofing material wears out.
Wind-driven leaks on slopes
Homes facing the ocean take rain and wind from the side during storms. Water pushes under tile, shingle edges and wall flashings.
Balcony and deck failures
View decks over living space are common and hard on waterproofing. Failed coatings and drains lead to ceiling stains below.
Old roofs on older cottages
Some early 1900s homes carry multiple layers or tired board sheathing. Re-roofing them means a full strip and deck repair.
San Pedro permits through Los Angeles and coastal conditions
Because San Pedro is part of the City of Los Angeles, re-roof permits come from the Los Angeles building department, not a separate San Pedro city office. Homes in historic areas or coastal zones may need extra review for visible changes. We check what applies and handle the permit and inspection for you.
Hillside streets can be steep and narrow, so we plan deliveries and debris removal around access. We use corrosion-resistant fasteners and flashing near the water and check metal parts closely on every inspection. San Pedro is a short drive across the bridge from our Long Beach office, so storm calls get a fast response.

Questions from San Pedro
Who issues roof permits for a San Pedro home?
San Pedro is a community within the City of Los Angeles, so the Los Angeles building department handles re-roof permits there. We file for the permit and schedule the inspection on San Pedro jobs. Some historic or coastal areas need extra review for visible changes.
Why does flashing fail so quickly on San Pedro roofs?
Salt air from the harbor and ocean corrodes metal far faster than inland air. Plain galvanized steel can rust through in a fraction of its normal life. We replace failed San Pedro flashing with corrosion-resistant metal and fasteners.
Can you waterproof a view deck on my San Pedro home?
Yes. We inspect the deck surface, drains, door thresholds and wall flashings to find where water gets in. Then we recoat or replace the waterproof layer so it holds up to sun and salt.
