A new roof in Santa Monica typically runs $14,000 to $32,000 for a standard 1,600 to 2,200 square foot home, with most architectural shingle installs landing between $18,000 and $26,000 when the existing decking is sound. The job usually takes four to seven working days once permits clear. Call (325) 246-5075 to schedule a free estimate, and you’ll get a written price before any work begins.
We know Santa Monica roofing because we work it every week. The housing stock here runs from 1920s Spanish bungalows in Sunset Park to post-war ranchers off Pico Boulevard to modern builds in the Wilshire-Montana corridor, and each one presents a different decking condition, roof pitch, and attachment detail. Our crews are familiar with the city’s plan-check and inspection rhythm, and our Roof Installation team handles everything from a straightforward re-shingle to a full tear-off with re-decking on older homes. When you book with us, you get a live arrival time, a written scope of work, and before-and-after photo documentation on every single job in Santa Monica.
Why Crestview Roofing Is Santa Monica’s Preferred Roof Installation Company
The biggest complaint we hear from Santa Monica homeowners is that they got a price per square over the phone, then watched the number climb once the old roof came off. That never happens with us, because we walk the roof, inspect the decking, check the ventilation, and put the full scope in writing before anything gets torn off. The price on the page is the price on the invoice. That’s the working agreement on every roof replacement in Santa Monica we install, and it’s why homeowners in Ocean Park and North of Montana call us back when the next project comes up.
Dylan Pace runs our Santa Monica roofing operations, and he’s the person who reviews every written estimate before it goes out. When a homeowner on 23rd Street has a question about why we’re recommending ice and water shield on a low-slope section, Dylan can explain it in plain English: it’s a self-adhesive membrane that seals around nails and prevents water from backing up under the shingles, and on certain roof pitches in this coastal climate it’s worth every dollar. That level of clarity is what sets us apart from roofers who hand over a vague line item and hope you don’t ask.
We don’t post fake urgency and we don’t quote one number and bill another. What we do is answer the phone when you call, show up on the day and time we committed to, and send a digital invoice by text when the job’s done, with a 365-Day Done Right Promise in writing on every repair and every installation. For Santa Monica homeowners who’ve been burned by no-show contractors or surprise change orders, that visibility changes everything.
Roof Ventilation in Santa Monica
Roof ventilation in Santa Monica is a bigger piece of the installation than most homeowners expect, because the marine layer keeps mornings cool and damp while afternoon sun pushes attic temperatures high enough to bake shingles from beneath. The job involves balancing intake at the soffit with exhaust at or near the ridge, usually through a continuous ridge vent, box vents, or a combination depending on the roof geometry. Inadequate ventilation shortens shingle life and drives moisture into the attic sheathing, which is a problem we see regularly in older Santa Monica homes where insulation has been blown in over the eave vents.
Ventilation work in a re-roof
When we install a new roof on a Santa Monica home, we check whether the existing ventilation is actually moving air or just taking up space. On the 1940s bungalow off Franklin Street in North of Montana that we recently re-did, the original attic had three box vents and no soffit intake at all. That meant the ridge vent we installed would have pulled air from nowhere unless we added intake, so we cut in a properly sized soffit vent system while the roof was open. It’s a $1,200 to $2,800 line item depending on the linear footage and accessibility, but it’s the difference between a 20-year roof and a 12-year roof.
When ventilation drives the cost
Some homes in Santa Monica have cathedral ceilings with no attic cavity at all, which changes the ventilation strategy completely. In those cases we spec an above-deck system or a combination of intake and exhaust that follows the rafter bays, and that work runs $3,500 to $6,000 depending on the roof area and whether we’re tying into the new shingle installation or retrofitting an existing roof. The point is that ventilation isn’t an add-on you buy off a menu; it’s engineered into the roof, and the right approach depends on the home’s framing and orientation. Call (325) 246-5075 and we’ll walk your roof and tell you exactly what your attic needs.
Roof Flashing Installation in Santa Monica
Roof flashing installation in Santa Monica covers the metal strips and boots that seal the joints around chimneys, skylights, plumbing vents, dormers, and anyplace two roof planes meet. In a coastal climate where fog carries salt and morning condensation lingers, flashing failures account for a disproportionate number of the leaks we find in Santa Monica homes. A failed plumbing boot, for instance, can channel water straight down into the ceiling below the bathroom, and it often gets misdiagnosed as a shingle problem. We always replace flashing during a roof installation, never reuse it.
Chimney and skylight flashing
Chimney flashing in Santa Monica runs $450 to $1,200 per chimney when done as part of a full roof installation, depending on whether we need to cut reglet lines into the masonry and whether the existing cap is still sound. Skylight flashing is similar, running $350 to $800 per skylight for a new curb-mounted flash kit. When flashing is installed correctly on a new roof, you shouldn’t think about it for 15 to 20 years. When it’s done cheaply, a homeowner on Arizona Avenue near the Wilshire-Montana border ends up with a ceiling stain every time the first real rain of the season comes through.
Valley and sidewall flashing
Santa Monica’s older homes have a lot of intersecting roof planes and sidewall transitions, and those valleys are where we spend the most time getting flashing right on an install. Open valleys with metal flashing run $300 to $600 each depending on length, and sidewall flashing where a roof meets a stucco wall runs about $350 to $700 per wall line. On the Franklin Street bungalow, the leak the owner had been chasing for two seasons turned out to be a failed plumbing penetration boot, not the field shingles at all, so we replaced the boot and collar while the deck was open and closed everything up in one five-day window. Our flashing work is part of the written scope, covered by the 365-Day Done Right Promise, and photographed before and after so you can see exactly what was replaced.
Trusted Brands We Service in Santa Monica
We install and repair manufacturer-backed roofing systems from GAF, CertainTeed, and Owens Corning in Santa Monica, which covers the vast majority of architectural shingle work we do in the city. Many homeowners in the Ocean Park and Sunset Park neighborhoods ask specifically for GAF Timberline HDZ because they’ve seen it on neighbor roofs or read the wind ratings, and we stock those materials out of our Los Angeles warehouse so Santa Monica installs don’t wait on supply-chain gaps. We also work with Atlas and Boral when a specific profile or fire-rated assembly is called for, particularly on the northern edge of the city where the Very High Fire Hazard Severity Zone requirements apply. Material quality is never a question on a Crestview job, and if you want a specific shingle line, you’ll get it with a manufacturer warranty in writing.
Common Roof Installation Problems We See in Santa Monica Homes
- Skip sheathing on pre-1960s homes. A lot of Santa Monica’s original housing from the 1920s through the 1950s was built with 1×6 boards spaced a few inches apart, not solid plywood. Modern shingles can’t be nailed to gaps, so full re-decking is often required, which adds $4,000 to $8,000 for the average Santa Monica roof. A roofer who quotes a price per square without checking the decking is going to break that news to you after the tear-off begins, and you’ll be the one holding the change order.
- Wind-rated nailing patterns ignored. Coastal-adjacent wind exposure in Santa Monica is real, and an architectural shingle’s 130 mph rating only holds when the installation matches the manufacturer’s fastening schedule. Six nails per shingle in the right pattern matters here. We see installations from other companies where the nail count is wrong and the shingles start lifting within two seasons.
- Ventilation treated as an afterthought. Inadequate intake at the soffit combined with a ridge vent that’s blocked by blown-in insulation causes premature shingle aging and attic moisture. This is one of the most common problems we find when we strip an old roof on a Santa Monica home, and it’s also one of the cheapest to fix if it’s addressed while the roof is open rather than retrofitted later.
- Tear-off disposal and green-building rules. Santa Monica enforces construction and demolition waste diversion requirements that don’t apply to many neighboring cities. That means the tear-off material from your old roof has to go to a certified facility, and the cost of that disposal, typically $1,800 to $3,500 depending on the number of layers and the roof size, is a legitimate line item in a Santa Monica bid. If a bid looks suspiciously low, check whether it includes disposal.
Pricing for Roof Installation in Santa Monica, CA
Here’s what honest pricing looks like for a roof installation in Santa Monica. A standard architectural shingle re-roof on a 1,600 to 2,200 square foot home runs $14,000 to $32,000 total. A full tear-off with re-decking on an older Santa Monica home runs $20,000 to $40,000 or more depending on the decking condition and the number of layers being removed. Roof ventilation additions run $1,200 to $2,800 for a standard soffit-and-ridge setup, and flashing work runs $300 to $1,200 per chimney, skylight, or valley. Material choice moves the number: premium lines from CertainTeed or GAF add $1,500 to $4,000 over standard architectural shingles.

FAQs About Roof Installation in Santa Monica
Santa Monica sits in a designated Very High Fire Hazard Severity Zone in its northern hills and canyon edges, which drives Class A fire-rated assemblies and ember-resistant detailing on many roof installs you wouldn’t see in Culver City. Santa Monica also enforces its own green building and construction waste rules, so tear-off disposal costs and cool-roof reflectivity choices come into play here that don’t apply a few miles inland. The housing stock is also older, with more skip sheathing and more re-decking required on average. Call (325) 246-5075 for a Santa Monica-specific estimate.
It includes a full written scope and price before work begins, the tear-off and disposal of the existing roof, any required re-decking or framing repair, new underlayment and flashing, the shingle or roofing system installation, ventilation work, and a final cleanup with photo documentation before and after. Every job also includes the 365-Day Done Right Promise in writing. A typical Santa Monica install runs five to seven working days once permits clear. Give us a call and we’ll walk you through the full sequence for your specific roof.
Yes, most full roof installations in Santa Monica require a building permit, and the city’s plan check will review the roof assembly, fastening schedule, and fire-rated materials where applicable. We pull the permits ourselves and schedule the inspections, so you don’t have to navigate the Building and Safety office. Permit fees in Santa Monica typically run $500 to $1,200 depending on the scope. That cost is included in our written estimate.
Line them up side by side by scope, not just total price. Look for whether the bid includes tear-off disposal, permits, re-decking if needed, flashing replacement, ventilation work, and the specific shingle brand and model. A bid that’s $6,000 cheaper but omits re-decking or disposal is not cheaper. Our written estimates detail every line item, the brand and spec of materials, and the schedule, so you can compare apples to apples. Call (325) 246-5075 and we’ll send you the same format.
The honest answer is decking condition. On older Santa Monica homes with skip sheathing or water-damaged plywood, re-decking is a real cost that can’t be known until the old roof comes off, and it runs $4,000 to $8,000 for the average home. Soft rafter tails or framing repairs add more. This is why we walk the roof and inspect the attic before the estimate, and why we write the change-order process into the contract upfront: any additional work is documented in writing with a price before it’s done, never discovered after the fact. That’s the whole point of the written price.
