A roof replacement in San Pedro often uncovers more history than homeowners expect. Many houses in the harbor area were built generations ago and have been re-roofed, patched and added onto several times since. Planning well means allowing time for what lies under the old roof, choosing materials that can take the ocean air, and knowing each step before the crew arrives.
What sits under an old San Pedro roof
From Vinegar Hill and the streets near the waterfront up toward the hills, San Pedro has a deep stock of Craftsman bungalows, Spanish-style homes and mid-century houses. On these homes, tearing off the covering often reveals one or more of the following:
- Multiple layers: a newer roof installed over an older one, adding weight and hiding problems.
- Skip sheathing: spaced boards originally meant for wood shingles, which cannot properly support modern shingles without new solid sheathing over or between them.
- Water-damaged boards: soft or delaminated decking around chimneys, valleys and old skylights where leaks went unnoticed.
- Abandoned penetrations: covered-over vents or flues from appliances long since removed.
If you suspect a leak is already doing damage, book a roof diagnosis online now so the scope is clear before the rainy season.
Decking: the part of a roof replacement in San Pedro you can't skip
New shingles or tile are only as sound as the surface they are fastened to. Decking that is rotted, sagging or too thin will not hold nails well, can telegraph dips through the new roof and may void a manufacturer's warranty.
How decking is evaluated
Our 4-Phase Roof Inspection includes looking from the attic for stains, daylight, sag between rafters and damaged boards. Once the old roof is off, the crew walks the whole deck and marks soft areas.
Repair or re-sheet?
Scattered damage is usually handled by replacing individual boards or panels. When the roof has skip sheathing or widespread damage, installing new solid sheathing across the whole roof is typically the more reliable choice. The choice between plywood and OSB is covered in our article on plywood vs OSB roof decking.
Framing surprises
Older homes sometimes show undersized rafters or earlier alterations that were never properly tied in. If we find a structural concern, we explain it clearly and in writing so you can decide how to proceed.
Choosing materials for the harbor air
San Pedro sits on the water, and much of the town gets steady ocean breezes and salty marine layer mornings. That affects the material choice less than the details around it.
Composition shingles
Architectural shingles suit most bungalows and ranch homes, are lighter than tile and come in colors that fit the neighborhood. Choose a product rated for high winds, since gusts can come off the water and up the hillsides.
Tile
Spanish-style homes are natural candidates for clay or concrete tile. If the house was not originally built for tile, the framing must be checked before switching to a heavier material.
Metal components
Whatever the covering, drip edge, flashing and fasteners should be corrosion-resistant and compatible with each other. We explain more in our guide to salt air roof corrosion.
Under every covering, the underlayment is felt-free: we are The No-Felt Company, and felt is never part of our roofs.
Gutters and eaves
Many older harbor homes have fascia boards and rafter tails that have taken years of wind-driven rain. A replacement is the right moment to repair them, because new drip edge and gutters need a sound board to fasten to. If the gutters are being replaced separately, we coordinate the timing so the roof edge and the gutter work fit together rather than being done twice.
The project from start to finish
Here is how a typical Rescue Roofer roof replacement runs, so you know what each day brings.
Before work day
A Roofing Advisor reviews the inspection report with you, confirms material and color, and explains how decking repairs are handled if hidden damage turns up once the old roof is off. San Pedro is part of the City of Los Angeles, so permits run through the Los Angeles Department of Building and Safety rather than an Orange County city, and the schedule is built around its inspections.
Tear-off
Landscaping, windows and walkways are protected, and old roofing comes off down to the deck. Debris goes straight into a bin or truck.
Repairs and dry-in
Damaged decking is replaced and new underlayment goes down the same day, so the house is protected overnight.
Installation
Our T.E.A.M. Certified technicians install flashing, vents, drip edge and the new covering. "Warehouse on Wheels" trucks keep materials on hand so the job keeps moving.
Inspection and cleanup
The city inspection is completed, the yard is swept for nails and you get a final walk-through.

Frequently asked questions
How do I know if I need a full replacement?
Widespread granule loss, curled or brittle shingles, repeated leaks in different places and sagging lines are common signs. The inspection report will state whether repair still makes sense.
Can a new roof go over my old one?
On older San Pedro homes, a full tear-off is usually the better route because it lets us inspect and repair the decking. Layers also add weight and hide damage.
How long will I be without a roof?
The crew plans to open only as much roof each day as it can dry-in with new underlayment before leaving, so the house stays covered overnight throughout the project.
What affects the price of a San Pedro re-roof?
Roof size and pitch, the material you choose, the number of old layers, how much decking needs replacing and how easy the site is to access all play a part. Because hidden decking damage is common on older homes, we explain up front how any repairs will be handled so nothing comes as a surprise. Book a roof diagnosis and you get a clear estimate once the roof has been inspected.
