Fast, Reliable Roof Replacement Across Santa Monica
Roof replacement in Santa Monica typically costs between $14,000 and $28,000 for a standard asphalt shingle roof on a 1,500 to 2,000 square foot home, with clay tile and flat roof systems running higher due to material and labor complexity. Barnwood Roofing serves every Santa Monica zip code, from the bluff-top streets north of Montana down to Ocean Park near the Venice border. Call (855) 382-1073 to schedule a free estimate, and we’ll give you a straight answer about whether you need a full replacement or a targeted repair.
We know Santa Monica roofs because we’ve crawled across hundreds of them. The salt-laden marine layer that rolls in most mornings does more damage than any rainstorm. Our crews work in Santa Monica weekly, not occasionally, which means we know which streets get hit hardest by the onshore breeze and which building types hide water damage until it’s already rotting the decking underneath.
Why Barnwood Roofing Is Santa Monica’s Preferred Roof Replacement Company
Ruben Calloway built Barnwood Roofing around a principle that matters more in Santa Monica than almost anywhere else: inspect first, recommend second. Too many roofing companies in the coastal zone treat every inspection as a replacement sales call. We don’t. If your roof needs $800 in flashing repair, that’s what we’ll tell you. If it truly needs replacement, we’ll show you why with photos and measurements, not pressure.
The salt air problem isn’t theoretical to us. We’ve been on roofs off San Vicente Boulevard where the galvanized flashing looked like lace after four years. That experience shapes every recommendation we make in Santa Monica. We specify stainless steel fasteners and marine-grade flashing on every coastal job, not as an upsell but as the baseline. Ruben Calloway has made that the standard for any roof we install west of the 405, because he knows what the marine layer does to cheaper hardware.
Santa Monica homeowners who call us get a response in under 48 hours for a site visit, and our quotes are line-item specific. You’ll see the exact cost per square, the exact hardware spec, the exact timeline. No vague allowances. No “we’ll see once we open it up.” A roof is too important to buy blind.

New Roof Installation in Santa Monica
New Roof Installation in Santa Monica means building from the deck up, and it’s the right call when the decking has absorbed too much moisture from years of marine fog to support another layer. In Santa Monica, a full new roof installation typically runs $15,000 to $30,000 depending on square footage, material choice, and whether the existing roof needs complete tear-off down to the rafters. Homes in the 90401 and 90402 zip codes, where 1920s and 1930s construction is common, often need decking replacement included in the scope.
What Tear-Off and Decking Replacement Involves
We strip the old roofing to expose the decking, then check every sheet for rot. In coastal Santa Monica, decking along the eaves and valleys is usually the first to go because that’s where fog moisture collects and sits. We replace damaged sheathing with CDX plywood rated for the marine moisture load, then install a synthetic underlayment that resists the wicking that destroys older felt products.
Specifying Hardware for Salt Air
The fasteners and flashing are where coastal roofs fail first. We specify hot-dip galvanized nails at minimum, and stainless steel for any home within a half mile of the bluff edge. That’s the difference between a roof that lasts 30 years and one that starts leaking at year six. The upgrade adds a few hundred dollars. Replacing corroded fasteners later costs thousands.
Reroofing in Santa Monica
Reroofing in Santa Monica means installing a new roof over an existing deck that’s still structurally sound, and it’s a route we recommend when the decking hasn’t been compromised by the persistent damp that the marine layer pushes under old shingles. In Santa Monica’s coastal climate, a reroof over a good deck typically costs $11,000 to $18,000 for asphalt shingles, with clay tile and Spanish-style profiles running $25,000 to $45,000 depending on the tile type and the complexity of the roof lines.
When the Decking Is Still Solid
Not every old roof in Santa Monica is hiding rot. If the attic is well vented and the original decking is still firm, we can strip the old shingles, replace the underlayment, and install a new roof without full deck replacement. This saves on material and labor while still giving you a completely new roof surface. Our inspection determines whether your deck qualifies, and we’ll show you the evidence either way.
Handling Roof Geometry on Older Homes
Santa Monica’s 1920s and 1930s bungalows often have complex hips, gables, and eyebrow details that make reroofing more involved than a standard suburban tract home. Our crews have reworked these geometries enough to know where the valleys collect fog moisture and where flashing needs extra attention. That’s a skill set you don’t get from a crew that only does big flat roofs inland.
Trusted Brands We Service in Santa Monica
We work with Owens Corning, CertainTeed, and IKO among our seven manufacturer relationships, which means we can match the right material to your Santa Monica home rather than pushing whatever a single-brand shop has in stock. For a bluff-top home on Adelaide Drive, we might specify an Owens Corning Duration with its thicker granule layer for salt resistance. For a Sunset Park rancher, a CertainTeed Landmark might be the better fit for its wind warranty. We stock local inventory for Santa Monica customers through our Inland Empire supply chain, so typical installations move quickly once permits clear.

AfterCommon Roof Replacement Problems We See in Santa Monica Homes
- Galvanized flashing corroding in under a decade: The salt fog along the Palisades and Ocean Avenue corridors eats standard galvanized flashing fast. We replace it with stainless steel or hot-dip galvanized hardware as a default on any coastal spec roof.
- Moss and algae lifting shingles on shaded north-facing slopes: The marine layer keeps north-facing Santa Monica roof planes damp for months. Moss roots work under shingles, lifting them and letting water reach the underlayment. We address this with proper ventilation and algae-resistant shingles.
- Rotting decking on poorly ventilated flat roofs: Mid-century apartment buildings and condo clusters in the 90411 area often have low-slope roofs with inadequate airflow. Moisture trapped between the membrane and the decking rots plywood from the inside out, and you won’t know until we open it up.
- Clay tile roofs failing at the battens: Many original Santa Monica Spanish and Mediterranean homes have clay tile, and the battens those tiles sit on degrade in the damp air. The tiles themselves last, but the support structure doesn’t. We re-lay salvaged tile with corrosion-resistant battens and stainless fasteners.
Pricing for Roof Replacement in Santa Monica, CA
Here’s what we see in Santa Monica’s current market. A full tear-off and asphalt shingle roof on a 1,500 to 2,000 square foot home runs $14,000 to $24,000. A reroof over solid decking runs $11,000 to $18,000. Clay tile roofs, which many Santa Monica homeowners need to match their home’s original Spanish or Mediterranean character, run $25,000 to $45,000 depending on tile profile and roof complexity. Flat roof replacement on a mid-century apartment building runs $12 to $18 per square foot.

FAQs About Roof Replacement in Santa Monica
Yes. Salt-laden fog and constant humidity corrode standard galvanized flashing and fasteners in three to five years on bluff-top Santa Monica homes, while inland roofs get decades from the same hardware. We specify stainless steel fasteners, hot-dip galvanized flashing, and marine-grade underlayment on every coastal-spec roof we install. That’s the difference between a roof that lasts and one that starts leaking before the warranty expires. Call (855) 382-1073 to get a quote that spells out exactly which hardware goes on your roof.
The Coastal Commission reviews re-roofing projects in the coastal zone, which covers most of Santa Monica west of Lincoln Boulevard and all bluff-edge properties. If your roof profile changes significantly in height, material, or drainage pattern, you may need a coastal development permit before work begins. We have experience navigating these reviews and can tell you early whether your project is likely to trigger one. The right material choice often avoids the permit trigger entirely. Call (855) 382-1073 for an assessment that includes a realistic permit outlook.
We work across seven manufacturers, including Owens Corning, CertainTeed, and IKO, which means we’re not pushing a single product line to meet a quota. For a Santa Monica home facing direct ocean exposure, we might lean toward an Owens Corning Duration for its thick granule surface. For a home in Sunset Park with more tree cover, moisture resistance might lead us to a CertainTeed line. The recommendation comes from your roof’s exposure and your budget, not from what’s sitting in our warehouse. Call (855) 382-1073 to talk through options with a real roofer, not a sales script.
A roofing square is 100 square feet of roof surface, and a typical Santa Monica bungalow runs 15 to 22 squares. This matters because every quote you get should be broken down per square, so you can compare apples to apples between contractors. Roof geometry, hips, valleys, and penetrations all add to the effective square count because they slow installation and increase waste. We always break our quotes down by square, with the material spec listed for each. Call (855) 382-1073 for a line-item quote you can actually compare.
Yes, and we do it often in the 90401 and 90402 zip codes where original clay tile is common. We salvage the original tiles where they’re still sound, re-lay them on corrosion-resistant battens with stainless fasteners, and replace broken pieces with matching profiles. Where the original tile is beyond saving, we source new clay tile that matches the profile and color, navigating whatever Coastal Commission review the change triggers. We’ll show you samples and explain the durability difference between salvaged and new clay. Call (855) 382-1073 to schedule a free inspection and tile match assessment.
