Why Crestview Roofing Is Santa Monica’s Preferred Roof Replacement Company
Santa Monica homeowners call us because we scope the job correctly the first time. That matters here more than most places. The combination of pre-war housing stock, coastal salt air, and strict city inspection requirements means a roofer who under-scopes the work will hit you with change orders once the old roof comes off. We don’t do that. Our written proposal includes the decking assessment, flashing specs, permit fees, and disposal costs before you sign anything.
Our team is led by Dylan Pace, and every technician who arrives at your Santa Monica home is background-checked and uniformed. You’ll see a name and photo before the crew pulls up. We’ve worked on bungalows near SMC, mid-century flat roofs off Wilshire, and newer construction in the Pico District, so we know how different housing types here behave during tear-off and replacement. We don’t guess. We scope it, price it, and put it in writing.
The result is a roof replacement process where you always know what’s happening, what it costs, and what comes next. That’s The Relay Visibility Guarantee, and it governs every job we do in Santa Monica.
Reroofing in Santa Monica
Reroofing in Santa Monica means stripping the existing roof down to the decking, repairing or replacing whatever is damaged underneath, and installing a new roofing system. On a standard 1,500 to 2,000 square foot single-story home, a full reroof with architectural shingles here runs $16,000 to $24,000. Most jobs take four to seven working days depending on the number of layers we’re removing and what we find beneath them.
What We Find Under Old Santa Monica Roofs
On a 1940s bungalow near Idaho Avenue and 17th Street, our crew stripped three layers of old composition shingles down to the original 1×6 skip sheathing, replaced rotted fascia, and added solid decking to meet current code. Then we installed Roof Replacement materials including GAF Timberline HDZ architectural shingles with ice and water shield in the valleys, a new drip edge, and a ridge vent. The homeowner had gotten two other bids that never mentioned the skip sheathing or the salt-air flashing issue. Our scope spelled out both, and the job passed Santa Monica’s final inspection without a single correction notice.
Why Multiple Layers Change the Math
Many pre-war Santa Monica homes have two or three layers of old roofing stacked on top of each other. That adds disposal weight, time, and dump fees, and it’s one of the most common causes of surprise change orders from roofers who didn’t check before quoting. We inspect the roof system with a core sample during the estimate so we know exactly how many layers we’re removing before we write your price.
Flat Roof Replacement in Santa Monica
Flat roof replacement in Santa Monica requires specific attention to drainage and decking condition, because mid-century and apartment-style flat roofs are common on the city’s east side and near the ocean. A typical flat roof replacement here runs $22,000 to $35,000 for a single-family home or small multi-unit building, depending on the condition of the existing decking and whether we need to add positive drainage or new insulation. Most flat roof jobs take one to two weeks.
Drainage and Ponding Water
Flat roofs in Santa Monica fail most often from ponding water, not from membrane failure. If the original roof was built without enough slope, water sits, and the membrane breaks down early at those low points. When we replace a flat roof, we check the drainage plan and, if needed, install tapered insulation or additional scuppers to move water off the roof. That’s part of a proper scope, not an add-on.
Salt Air and Fastener Corrosion
Santa Monica’s coastal salt air accelerates corrosion of roof fasteners, vents, and flashing. Galvanized steel and standard aluminum can fail within a few years this close to the ocean, so we spec stainless steel or copper flashing and fasteners on nearly every reroof and flat roof replacement here. It adds a few hundred dollars to the material cost and buys you a decade or more of extra life. We write it into the proposal because it should be standard practice, not an option.
Trusted Brands We Service in Santa Monica
We install manufacturer-backed roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Santa Monica homes, we most often recommend GAF architectural shingles for pitched roofs and Boral or Tamko systems for flat work, because they hold up well in our specific coastal environment. We keep inventory staged at our Los Angeles office and coordinate deliveries to Santa Monica by the day of install, so your materials arrive when the crew does, not days before, sitting on your driveway.
Common Roof Replacement Problems We See in Santa Monica Homes
- Salt air corrosion of flashing and fasteners. Homes within a mile of the ocean in Santa Monica show accelerated rust on galvanized metal. We specify stainless or copper on every coastal job, because standard materials corrode years earlier here than they would inland.
- Multiple old roof layers. Pre-war bungalows in Sunset Park and Mid-City often have two or three layers of composition shingle. Removing those layers adds dump fees and labor, and under-scoping that work is the number one cause of mid-job change orders.
- Skip sheathing on older homes. Homes built before the 1960s in Santa Monica frequently have 1×6 skip sheathing with gaps between boards instead of solid plywood. Current building code requires solid decking, so we include an upgrade in our scope rather than spring it on you after tear-off.
- Flat roof drainage failures. Mid-century flat roofs near Ocean Park and the Pico District often lack proper slope or have failing drains. Water ponds, the membrane breaks down, and leaks follow. A proper replacement corrects the drainage problem, not just the surface membrane.

FAQs About Roof Replacement in Santa Monica
Yes. The City of Santa Monica requires a building permit for roof replacement, and the work must pass a final inspection. We pull the permit, schedule inspections, and make sure the job passes before we call it done. That’s part of your written scope, not an extra fee.
Salt air corrodes standard galvanized flashing and fasteners much faster than inland conditions do. We use stainless steel or copper flashing and fasteners on roofs within a mile of the ocean, which extends the life of the roof by years. This upgrade is included in our Santa Monica proposals.
Most full replacements take four to seven working days for a pitched roof and one to two weeks for a flat roof. Weather, decking repairs, and inspection scheduling can add time. We’ll give you a realistic calendar in your proposal before we start.
If your home has skip sheathing or rotted decking, yes. Homes built before the 1960s often have 1×6 boards with gaps that don’t meet current code, and Santa Monica inspectors require solid decking before we install the new roof. We assess decking during the estimate so the cost is in your price from day one.
We install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For most Santa Monica homes, we recommend GAF architectural shingles for pitched roofs and Boral or Tamko for flat systems, chosen for coastal durability. You’ll see the exact product in your line-item quote.
