Fast, Reliable Roof Replacement Across Santa Monica
Roof replacement in Santa Monica typically runs $12,000 – $28,000 for a full tear-off and new architectural shingle system on an average 1,400 – 1,800 sq ft home, with flat roof membrane work landing between $9,000 and $19,000 depending on decking repairs and insulation upgrades. We’re Huntington Beach Roofers, and we’ve worked enough Santa Monica jobs – from the bungalow courts off Ocean Park Blvd to the apartment blocks lining Lincoln Blvd – to know that no two roofs here fail the same way. The marine layer changes everything. If you’re seeing water stains, curling shingles, or you’ve simply got a roof that’s past its 25-year mark, call (833) 467-4901 and we’ll start with an honest inspection, not a sales pitch.
Why Huntington Beach Roofers Is Santa Monica’s Preferred Roof Replacement Company
We carry materials from seven manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – which means the product recommendation follows your roof’s needs and your budget, not our inventory. Most Santa Monica contractors push one brand because that’s what they stock. We don’t have that problem. If a certain shingle line is backordered or simply the wrong call for your home’s exposure to salt fog and marine moisture, we move to the alternative without skipping a beat. That’s the value of a seven-brand portfolio.
Neil Stratton leads our team, and his approach is simple: we inspect first, recommend second. A roof replacement is too expensive to guess at. When we walk a Santa Monica roof, we’re looking at the underside of the decking, the condition of the flashing, whether the original underlayment is still shedding water – details a curb-level estimate misses. Our customers in Santa Monica consistently tell us the same thing: the estimate process itself told them more about their roof than any previous contractor ever had.
Response time matters when you’re dealing with a failing roof. We schedule Santa Monica inspections promptly and keep every appointment window tight. Your call reaches a person, not a call center. If you’re in the 90401 ZIP code or up near San Vicente, you’re still a direct drive for our crews, and we treat Santa Monica work as core territory – never a side trip.

Asphalt Shingle Roof Replacement in Santa Monica
Asphalt Shingle Roof Replacement in Santa Monica usually means tearing off one or two layers of old material, inspecting what’s underneath, replacing any compromised decking, then installing new underlayment, leak barriers, and architectural shingles rated for coastal wind exposure. For a typical Santa Monica bungalow, you’re looking at $13,000 – $22,000 for the complete job, with premium lines from Atlas or Tamko landing on the higher end when you factor in upgraded underlayment and ridge ventilation. Salt air and marine moisture eat ordinary fasteners quickly, which is why we spec corrosion-resistant nails and flashing on every Santa Monica job we do.
The biggest variable in any asphalt shingle replacement here isn’t the shingle itself – it’s what we find when the old roof comes off. Homes built in the 1920s through 1950s often have original wood shake underneath, which rots from the underside in Santa Monica’s damp climate. That rot spreads to the decking, and suddenly a straightforward shingle job becomes a structural repair. We plan for this in our estimates so you’re not blindsided.
Decking and Underlayment Assessment
Before we quote an asphalt shingle replacement, we check the sheathing from the attic side when access allows. Soft decking is common in Santa Monica homes near the coast, where fog drip keeps attics humid year-round. If the plywood or planks have lost integrity, the shingles won’t adhere properly and the roof won’t pass inspection.
We write decking replacement allowances into our contracts up front, so there’s a clear number attached to that work before we start. If we find more rot than expected once the tear-off happens, you approve the additional cost in writing before we proceed. No change orders you didn’t see coming.
Ventilation and Salt Corrosion Protection
The north-facing slopes of homes west of Lincoln Blvd rarely dry out fully, which makes moss and algae a constant battle. Proper ridge and soffit ventilation helps mitigate the moisture that feeds that growth, but in Santa Monica it’s never fully eliminated. We install aluminum ridge vents and corrosion-resistant fasteners as standard practice, not an upsell.
Architectural shingles from GAF and CertainTeed carry manufacturer wind ratings that matter in Santa Monica, especially during those Santa Ana events that rip through canyons and test ridge caps. We match the shingle to the roof’s actual wind exposure, not a generic recommendation.
New Roof Installation in Santa Monica
New Roof Installation in Santa Monica covers everything from new construction on infill lots in the 90410 and 90411 ZIP codes to full reroofs on 1960s apartment buildings where the original flat roof membrane has reached the end of its service life. For a new shingle roof on a typical Santa Monica home, budget $12,000 – $25,000, while flat roof installations on multifamily properties generally run $9,000 – $19,000 per building depending on square footage, insulation requirements, and drainage work. New construction jobs often carry additional costs for Title 24 compliance, including cool roof ratings and specific insulation values.
Santa Monica’s building department has its own energy requirements beyond state code, particularly for new installations. We pull permits on every job, coordinate the inspections, and make sure the final product passes without rework. That’s part of the service, not an add-on. If you’re building new or replacing a roof on a property you plan to hold for decades, the material selection conversation matters more here than anywhere else in greater LA.
New Construction Coordination
Building a new home in Santa Monica means the roofing contractor answers to a general contractor, an architect, and a building inspector – often all in the same week. We’ve worked those jobs across the 90402 ZIP code and down toward the beach, and we know the rhythm. Our team coordinates with framing crews, electricians, and stucco contractors so the roof goes on when it needs to, with the right underlayment and flashing installed before the next trade touches it.
Because we carry seven brands, we can spec exactly what the plans call for without substitution drama. If the architect specifies Boral or GAF, that’s what goes on. If the builder wants an economy option to keep the budget tight, we’ve got that too – and the final product is still installed to manufacturer spec.
Flat Roof Membrane Systems
The flat-roofed 1960s apartment blocks near the beach are a Santa Monica signature, and they fail in predictable ways. Constant fog drip plus poor drainage means ponding water, and ponding water kills membranes years early. We replace those systems with multi-ply or single-ply membranes graded properly to shed water, with attention to the parapet flashings and scuppers that often get ignored.
Salt air accelerates fastener corrosion on flat roof penetrations faster than anywhere we work. We use stainless and coated fasteners on every Santa Monica flat roof, because the alternative is callbacks for leaks that start at the mechanical screen feet and roof drains.
Trusted Brands We Service in Santa Monica
We’re authorized to install products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we keep common components for each brand in our local inventory. For Santa Monica homeowners, that means when we need to match a specific shingle color or profile on an existing roof, we aren’t waiting on a distributor shipment from Riverside. When a 1950s home in Sunset Park needs replacement shingles that blend with the original, we can pull from stock and get the job moving. Our Roof Replacement team matches the material to the roof and the budget, not the other way around. If you’re repairing instead of replacing, we use the same supplier network – no scrambling for obsolete profiles.

AfterCommon Roof Replacement Problems We See in Santa Monica Homes
- Underside rot in original wood shake. The marine layer keeps moisture trapped under shake roofs, so the top can look intact while the underside has turned to pulp. We discovered exactly this on a 1920s Spanish Colonial Revival in the 90402 ZIP code – the shake looked weathered but passable from the curb, yet the decking underneath was so soft our crew couldn’t walk it safely during tear-off.
- Clay tile cracking from bluff-side settling. Homes near the palisades sit on sandy soils that shift, and rigid clay tile doesn’t flex. Once the original underlayment degrades, cracked tile channels water straight into the attic. Replacement means addressing the tile bed and the underlayment together, not patching individual tiles.
- Membrane failure on flat-roofed apartment blocks. The 1960s beach-adjacent buildings in the 90401 ZIP code pond water constantly because fog drip never stops and original drainage was marginal. We replace those membranes with properly graded systems and rebuild the scupper details that fail first.
- Salt corrosion on flashing and fasteners. Salt-laden fog eats galvanized flashing faster than any inland climate. We replace failed flashing with aluminum or stainless and use coated fasteners that actually last near the Pacific.
Pricing for Roof Replacement in Santa Monica, CA
A typical asphalt shingle roof replacement in Santa Monica runs $12,000 – $22,000 for a bungalow or Spanish Colonial Revival home between 1,200 and 1,800 square feet.

FAQs About Roof Replacement in Santa Monica
Santa Monica’s marine layer keeps roofs damp for much of the year, so rot often starts on the underside of your wood shake or decking, not the top – a roof that looks fine from the curb can be structurally compromised underneath. The moisture means your replacement needs upgraded underlayment, corrosion-resistant fasteners, and proper ventilation. Call (833) 467-4901 and we’ll inspect your roof from the attic side before quoting so that hidden rot isn’t a surprise.
Expect that the shake has rotted from the underside at minimum, and that the decking underneath may need partial or full replacement. On a 1920s Spanish Colonial Revival in the 90402 ZIP code, our crew found that exact condition – soft decking, outdated attic wiring, and shakes that had lost their structural integrity from years of trapped marine moisture. We work through those findings with written approval before any additional repair, and we bring in licensed electricians when the permit triggers wiring upgrades. Call (833) 467-4901 for an inspection that tells you what’s actually under your roof.
Yes, roof replacement in Santa Monica requires a building permit, and the inspection process can trigger code upgrades – most commonly insulation requirements under Title 24 and, in older homes, attic wiring corrections or structural reinforcement if the inspector flags compromised framing. We pull permits on every job and price the likely upgrades into your estimate so you aren’t surprised at inspection. Call (833) 467-4901 for a line-item quote that accounts for Santa Monica’s permit realities.
We use corrosion-resistant fasteners, stainless or aluminum flashing, and underlayment rated for high-moisture environments on every Santa Monica job we do. Salt-laden fog eats standard galvanized flashing in years, not decades, so the material spec matters as much as the shingle itself. Call (833) 467-4901 to talk through what corrosion protection looks like for your specific roof.
A square is 100 square feet of roof surface, and it’s the unit most roofing contractors use to price both tear-off and installation. When your quote says 20 squares, that’s 2,000 square feet of roof surface – not the footprint of your home, though roof pitch makes those numbers differ. Understanding squares helps you compare our line-item quote to any other Santa Monica roofer’s bid, because not everyone calculates overhangs and valleys the same way. Call (833) 467-4901 for a quote that breaks down the square count, so you know exactly what you’re paying for.
