Get a Free Roofing Estimate From Your Trusted Roofing Company
Three bids, three different numbers, and none of the contractors will quote a price until someone climbs on your roof. That's the part of roofing that wears people down, and it's the part we rebuilt.

Every San Mateo project starts online, not with a sales visit at your kitchen table.

About 44% of the city's homes are detached single-family and roughly 39% sit in buildings with five or more units, so residential homeowners and apartment or mixed-use owners get equal attention here.
Our headline service. Your roof replacement begins with satellite measurement and an online number, and decking is confirmed with photos after tear-off rather than guessed from the driveway. Architectural asphalt shingles, underlayment and ventilation get specified before installation day, not improvised on the roof.
Not every leak means a new roof, and we'll say so. Plenty of San Mateo roof repairs come down to chimney flashing, a failed pipe boot, missing shingles after a windy stretch, or a valley that was never detailed well. Take our 30-Second Quiz if you're weighing repair against replacement.
You don't need a day off work to price a roof. Satellite measurement builds the estimate, a short drone inspection confirms it, and a Zoom call covers the rest. Routine roof inspections and seasonal maintenance follow the same path.
On the flat eastern side of San Mateo, gutters and downspouts do most of the drainage work. We handle gutter installation and replacement alongside a new roof, plus skylights when they're part of the scope.
Our commercial roofing services include TPO flat roof installations with the same photo-documented process property managers can forward to ownership. Commercial clients get the work staged around business hours.
Active leak or storm issues? Call (844) 796-5439 and we'll talk through stabilization before water damage reaches your drywall.
Credentials you can verify, a price you can see before anyone knocks, and a named project manager who keeps talking after the deposit clears. Run CSLB License #1108246 through the CSLB's public lookup and confirm we're fully licensed and insured before you hire anyone. We're an Owens Corning Platinum Preferred Contractor, Diamond Certified (CERT 2862, 4.8 stars from 28 verified phone surveys), and rated 4.9 on Google, 4.9 on Yelp and 4.8 on Thumbtack as displayed on our site.
If you've been burned before, verification beats reassurance. So does documentation: photos at every stage, written approval for anything added, and a permit we pull and close out ourselves. Quality, reliability and professionalism show up in a paper trail, which is why we leave one.
We've been in business since 2020, with over two decades of experience in the roofing industry behind our leadership, and we hold crews to high standards on every job site. We won't be the lowest bid in your inbox, and we'll say that plainly. Low numbers get made up somewhere: thinner materials, skipped ventilation, or change orders once the old roof is off. Tell us your budget and we'll show you what it buys.
As an Owens Corning Platinum Preferred Contractor, Symplify offers the Owens Corning Platinum Protection Warranty on qualifying shingle installations: 50 years of non-prorated material coverage and 25 years of workmanship coverage backed by Owens Corning, registered in your name when the job is done.
Most roof replacements take 2 to 3 days. Larger or more complex roofs can take longer. The City won't take same-day inspection requests, so we build that into the calendar up front.
San Mateo roofs vary more house to house than most Bay Area cities, so geometry and reroofing history matter more than neighborhood averages. Baywood, Aragon and San Mateo Park hold older, architecturally varied homes. Hillsdale reads suburban. Bay Meadows, built on the former racetrack south of Highway 92, is newer construction entirely.
Terrain splits the city. The east side near the Bay is essentially flat, which puts the load on gutters and drainage. Western streets rise past 20-degree slopes in places, which changes access and material handling for the roofers working the job.
Then there's weather. Marine air, summer fog, and roughly 20 inches of average annual rainfall concentrated between October and April. Hail is a non-issue here; wind and water are not. City code inputs list an 85 mph three-second-gust wind speed and roof drains sized for at least two inches of rain per hour. Wet-season work means forecast monitoring and proper dry-in, never a promise of rain-free days.
An active CSLB license you can look up, proof they're licensed, bonded and insured, a manufacturer certification that ties warranties to real training, and a written scope with a materials list instead of the word "reroof." Ask how hidden damage gets documented, which roofing professionals will be on your roof, and what your cancellation rights are before you sign.
Yes, and we handle it. Roofing permits are issued by the City of San Mateo Community Development Department, Building Division at City Hall, 330 West 20th Avenue. Reroofing is classified as an Express Building Permit, which needs no plan check when nothing else triggers review, and fees are set by property type and, for multifamily or commercial buildings, size.
Start online and you'll have a number before anyone comes out. Our instant online estimates are 95% accurate, and generally only require a short drone visit to confirm a final price. Roof geometry, material, access, existing layers and solar all move the figure, which is why the instant quote tool asks about your actual roof. It's free to use.
You see a photo and approve the change before we proceed. Nothing gets added silently, because the quality of roof installations depends on what's underneath them.

If you searched for roofing companies near me, our office area is Walnut Creek, and we say so plainly.
