Our Roof Replacement & Installation Services in San Pedro
Full Roof Replacement
Most San Pedro homes we’re called to were built between the 1920s and 1950s, and many still carry original wood skip-sheathing under aging shingles or tar-and-gravel. That sheathing was never meant to endure decades of marine-layer saturation. During a full replacement, we strip to the deck and assess every board. In the 90731 ZIP near the harbor, we routinely find rot extending past what a surface inspection would suggest. We replace with proper plywood decking, add ventilation where the original builder didn’t, and finish with materials rated for coastal exposure. Our Roof Replacement & Installation team documents every stage with photos you can review.
New Construction Roofing
New builds in San Pedro - whether a custom home on the Palos Verdes hills or an addition off Gaffey Street - need roofing specified for the local environment from day one. We design assemblies that account for the sustained wind uplift off the water and the humidity cycling that shortens shingle life. Proper underlayment, ice-and-water shield at vulnerable transitions, and hardware selected for corrosion resistance. We coordinate with your builder and pull permits through the City of Los Angeles. The price we quote is the price you pay - no surprises at final invoice.
Asphalt Shingles
Asphalt shingles remain the most common choice for San Pedro’s residential re-roofs, and we install GAF Timberline and Owens Corning Duration lines with specific adaptations for this market. Standard manufacturer warranties are tested in drier climates; here, the constant humidity cycling and salt particulates mean we specify upgraded underlayment and stainless or hot-dipped fasteners as baseline, not upgrades. In the 90731 ZIP closest to the port, we’ve learned that cutting corners on hardware leads to callbacks within three to five years. We don’t do callbacks.
Metal Roofing
Metal roofing performs exceptionally well in San Pedro’s climate when specified correctly. We install standing-seam and stone-coated steel systems from quality manufacturers, using marine-grade fasteners and separation membranes to prevent galvanic corrosion where dissimilar metals meet. The reflective properties help with summer heat, and the wind resistance exceeds what’s needed for the bluff-top gusts. For homes near the harbor, we specify aluminum or zinc-coated products over standard steel. Done right, a metal roof here outlasts three asphalt shingle cycles.
Tile Roofing
Spanish and Mediterranean tile fits the architectural character of San Pedro’s older neighborhoods, particularly the 1920s-1940s homes near Point Fermin and along Meyler Street. We install clay and concrete tile systems with proper batten spacing, corrosion-resistant fasteners, and underlayment selected for the marine environment. Tile is heavy - we verify that the existing structure can carry the load, and we reinforce where needed. Original tile can often be salvaged and reinstalled with new underlayment, preserving the home’s character while solving the waterproofing problem underneath.
Flat Roofing
Low-slope sections on San Pedro’s older homes - typically additions, porches, or garage roofs - were often finished with built-up tar-and-gravel that’s now decades past service life. Wind-driven salt spray degrades reflective coatings and accelerates cracking. We replace these with TPO or modified bitumen systems, properly sloped for drainage and sealed at all penetrations. The harbor moisture means ponding is never acceptable; we fix the substrate and the drainage before we install the membrane.

Trusted Brands We Service in San Pedro

We stock common accessories and hardware locally, so we’re not waiting on shipments when your roof is open. Fast turnaround matters when marine weather can turn in an afternoon.
Common Roof Replacement & Installation Problems We See in San Pedro Homes
- Galvanized hardware failure near the harbor. Standard drip edge and roofing nails show visible rust within 2-4 years in the 90731 ZIP. We specify stainless steel or hot-dipped galvanized as standard practice, not an upsell.
- Rotten skip-sheathing under original wood roofs. Decades of marine-layer moisture destroy the plank decking common in pre-1950 San Pedro homes. Full deck replacement is often necessary before new roofing can be installed.
- Premature cracking on low-slope built-up roofs. Wind-driven salt spray and harbor particulates degrade reflective coatings, leading to thermal cracking and ponding. These systems rarely reach half their rated lifespan here.
- Wind uplift at ridge caps and eave edges. San Pedro’s bluff topography channels southwest winds directly onto roof surfaces, stressing shingles at their most vulnerable points. We use six-nail patterns and manufacturer’s high-wind accessories in exposed locations.

San Pedro’s Unique Roofing Environment: What We’ve Learned
San Pedro sits directly above the Port of Los Angeles - the nation’s busiest container port - meaning roofs here are exposed to a double corrosive assault: open-ocean salt air from the Pacific and the industrial marine atmosphere of diesel exhaust, sulfur compounds, and harbor particulates that blanket the bluffs. This combination degrades galvanized flashing, fasteners, and reflective coatings measurably faster than in neighboring coastal cities like Redondo Beach or Torrance that lack a major working port immediately below their residential hillsides.
On a 1940s Spanish Colonial Revival near Point Fermin in the 90731 ZIP, we found that standard galvanized drip edge had rusted through after only four years. We replaced the entire roof with GAF Timberline shingles, stainless steel fasteners, and hot-dipped drip edge to withstand the double assault of salt air and harbor particulates.
This isn’t theoretical. Roofers working the streets closest to the harbor bluffs routinely see failure patterns that inland contractors wouldn’t recognize. The near-zero freeze risk is offset by constant humidity cycling that shortens the effective life of standard composition shingles compared to manufacturer ratings tested in drier climates. We factor this into every specification we write for San Pedro homes.

FAQs - Roof Replacement & Installation in San Pedro
Your roof rusts faster because San Pedro’s position above the Port of Los Angeles exposes it to both open-ocean salt air and industrial harbor emissions - diesel exhaust, sulfur compounds, and metal particulates - that accelerate corrosion of standard galvanized hardware. In the 90731 ZIP, we’ve seen drip edge and roofing nails show visible rust within 2-4 years. We specify stainless steel or hot-dipped galvanized fasteners as standard for harbor-proximity homes. Call (877) 367-1429 for a free inspection - we’ll show you exactly what your roof is facing.
Yes, in most cases. San Pedro’s pre-1950 homes commonly have skip-sheathing - spaced wood planks - that was never designed for sustained marine-layer moisture. We routinely find rot and deterioration during tear-off, particularly in the 90731 and 90732 ZIP codes. Replacing with solid plywood decking provides a proper substrate for modern underlayment and extends the new roof’s lifespan significantly. We’ll photograph the deck condition during inspection so you can see what you’re working with. Free estimates at (877) 367-1429.
No - asphalt shingles in San Pedro typically underperform their manufacturer ratings because the constant humidity cycling and salt particulates accelerate granule loss and sealant strip degradation. A shingle rated 30 years in a dry climate may deliver 18-22 years here. We compensate with upgraded underlayment, proper ventilation, and corrosion-resistant fasteners. The 90-Day Done Right Promise covers our workmanship regardless. For exact pricing on your home, call (877) 367-1429.
Aluminum or zinc-coated (Galvalume) standing-seam metal roofing performs best in San Pedro’s salt-air environment, as both materials resist the chloride corrosion that attacks standard steel. We use marine-grade fasteners and separation membranes to prevent galvanic reaction at contact points. Stone-coated steel is another strong option if you want the tile or shingle aesthetic with metal durability. We’ll walk you through the choices during a free estimate - call (877) 367-1429.
Look for rust streaks on fascia and gutters, lifted or curling shingles at eave edges, and visible rust on exposed fasteners or flashing - these are early indicators. On the roof itself, galvanized drip edge will show orange staining before it fails completely. We document all of this during our photo inspection, and we’ll show you what we find from your actual roof, not from a brochure. If you’re in the 90731 ZIP or near the harbor bluffs, we recommend inspection every 2-3 years. Schedule yours free at (877) 367-1429.
