Get a Free Roofing Estimate From Your Trusted Roofing Company
Almost every roofing company in San Jose, CA advertises free estimates. Almost none of the roofing contractors you call will tell you a number until someone has spent an afternoon on your roof, which means you book time off work just to learn what you're dealing with. That's the part we fixed first.
Symplify Roofing is a licensed and insured roofing company (CA CSLB License #1108246) and an Owens Corning Platinum Preferred Contractor serving homeowners, landlords and property managers with residential and commercial properties throughout San Jose, CA and all nine Bay Area counties. Our San Jose roofing services cover roof replacement, new roof installation, shingle roofing, flat and low-slope roofing, roof repairs, roof leaks, roof inspection, gutter replacement and commercial roof installation. And you can get a price for a new roof online before anyone sets foot on your property. Our instant online estimates are 95% accurate, and generally only require a short drone visit to confirm a final price.
If you've been typing "roofing companies near me" into a search bar and getting a wall of identical promises from San Jose roofing contractors, the criteria for a shortlist are simpler than they look: an active state license, manufacturer credentials that unlock a real warranty, a documented process with the City of San José for permits and inspection, and a named person who actually answers. Every outfit in the market calls itself the best roofing company in the South Bay, so the word is worth nothing on its own. Most Bay Area homeowners we meet have already collected two or three bids from San Jose roofers and still can't tell what separates them. Symplify puts all four in writing before you commit to anything.

We provide a full residential and commercial menu in San Jose, CA: roof replacement and new roof installation, shingle roofing, flat and low-slope roofing systems, roof repairs and leak work, drone roof inspection, gutter replacement, and commercial roofing services including TPO and flat roof installation, plus emergency roof services. Every one of them starts the same way, with an online estimate, a short drone confirmation, and photo documentation you keep. Roofing projects in the South Bay rarely fail because of the shingle itself. They fail at the details around it, the same details most roofing contractors compress into a single line on a one-page proposal, so that's where our scopes spend their words.
Full roof replacements are what we do most, and we scope every new roof the same way so you can compare our proposal to any other San Jose roofing company's line for line. A San Jose roof replacement from Symplify includes:
Most roof replacements take 2 to 3 days. Larger or more complex roofs can take longer. Hold that list up against what other roofing contractors hand you and the gaps tend to show themselves fast. See our roof replacement service page for the full scope.
Asphalt shingles are the most common roofing materials we replace in San Jose, and here they live a specific life. NOAA's 1991 to 2020 normal for its San Jose station is 16.14 inches of annual precipitation, with very little normal rainfall in July and August, so your shingles spend most of the year under sun rather than water. A shingle roof replacement in this climate is really a ventilation and deck project with shingles on top, which makes ventilation, deck condition and shingle color a single decision rather than three separate ones. Shingle color is as much an energy efficiency question as an aesthetic one. If your current asphalt shingles are cupping at the edges, dropping granules into the gutters, or looking noticeably worn on the south and west slopes while the north side still looks fine, that uneven aging is heat, not bad luck.
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.
Material choice in San Jose, CA is part aesthetics and part structure. Premium materials still leak without proper installation, so treat the roofing options below as systems rather than product names. Ask the roofing contractors you're talking to why they're proposing a given assembly, not just what it costs. Here's the short version of what goes where across the San Jose area and what each one asks of the project.
|
Roofing material |
Where it fits in San Jose |
What to plan for |
|
Asphalt shingles |
The majority of pitched roofs, from Willow Glen bungalows to the postwar tracts in Berryessa and Evergreen |
Ventilation and deck condition drive service life more than the shingle line you pick |
|
3-ply modified bitumen |
Flat and low-slope sections, Eichler-era rooflines, rear additions and carports |
Drainage, ponding and terminations matter more than the product name |
|
TPO |
Commercial buildings, apartment properties and HOA-managed communities |
HVAC curbs, roof access, staging and tenant notice get built into the schedule |
|
Tile |
Spanish Colonial Revival and mission-influenced homes, plus some hillside properties |
Completed assemblies over seven pounds per square foot require structural justification |
|
Metal roofing |
Porch roofs, accents and some modern rebuilds |
Panel profile, fastening and flashing transitions should be spelled out in the scope |
We replace flat and low-slope roofing across San Jose's mid-century tracts and on the mixed-slope rooflines that show up on additions, carports and rear extensions. San Jose identifies Eichler tracts in Morepark, Fairglen, Fairglen Additions, Hudson and Fairhaven, developed from 1952 through 1963, and those homes are exactly where bids tend to diverge wildly because roofing contractors propose different systems without explaining why. You may also be offered silicone roof coatings over an aging membrane. A coating can buy time on a sound assembly, but it doesn't rescue one that has already failed, and we'll show you photos of which situation you're in.
Our standard residential low-slope system is a 3-ply CertainTeed modified bitumen assembly, backed by the manufacturer's material warranty plus Symplify's workmanship warranty. Your drone report shows drainage, ponding and terminations before we quote the system, and our CertainTeed installations follow the manufacturer's written instructions for every detail the inspector will look at. CertainTeed installations also live or die at the edges, so drains, scuppers, curbs and wall terminations are itemized in your written scope rather than buried in a lump sum.
Not every leak in San Jose is a replacement, and we'll say so. San Jose treats work affecting less than 25% of the roof within a 12-month period as a repair that does not require a reroof permit, which is a useful dividing line for San Jose homeowners too: if the failure is confined to one valley, one flashing detail or one low-slope section, roof repairs are often the honest answer.
The roof repairs we're called out for most in the San Jose area follow a pattern. Cracked pipe boots around plumbing vents. Chimney and sidewall flashing that was caulked instead of counter-flashed. Skylight perimeters. Missing shingles after a windy stretch. The transition where a pitched roof dies into a flat addition, which is where two different roofing systems have to be made to agree with each other. Plenty of those roof repairs are half-day visits. We photograph the actual failure point before we recommend anything, because a leak that shows up over the dining room often starts several feet uphill, and visible roof damage from the ground is rarely the whole story.
Not sure which side you're on? Take our 30-second repair-vs-replace quiz, or start with our roof repair service and we'll document the damage before recommending anything.
A drone roof inspection gives you evidence, not a sales pitch. You receive photographs of the actual conditions on your roof, measurements taken from above rather than guessed from the driveway, and a written summary of roof condition describing what we'd do and why.
Roofing has always run on information you couldn't verify. A photo set you can open on your phone, keep, and show to a second roofing company removes most of that problem in one step. It's also what makes competing bids from different San Jose roofing contractors comparable, because everyone is finally looking at the same roof, and it turns three vague roofing estimates into three documents you can actually read side by side.
We install TPO and flat roof systems for San Jose commercial properties, apartment buildings and HOA-managed communities across the Bay Area. San Jose's 2020 housing stock was 52.5% single-family detached, 9.7% single-family attached, 34.5% multifamily and 3.3% mobile homes, so multifamily roofing projects are a real market here, not an afterthought.
Our commercial roofing and commercial roof installation scopes plan tenant notice, parking and staging, rooftop HVAC and equipment coordination, and roof access, with the same photo-documented reporting owners can forward straight to a board or an asset manager.
We handle gutter services as part of a roof replacement or on their own, respond to storm damage, and offer emergency roof services when water is already coming in. Call (844) 796-5439 and we'll triage it. If your loss involves insurance claims, we guide you through the documentation and give you photo evidence your insurance provider can actually work from; we're roofers, not adjusters, and we won't pretend otherwise.
We don't compete to be the cheapest bid in San Jose. We compete to be the San Jose roofing company you can actually verify, line by line, before you sign anything. Here is what there is to check.
Those numbers exist because someone outside this company asked homeowners about quality and customer satisfaction and wrote down the answers. Great customer service in roofing isn't a personality trait anyway. It's a system: one contact, scheduled updates, photos at each stage.
Symplify exists because the roofing industry's refusal to modernize stopped being an industry problem and became the customer's problem. Withheld pricing, estimates that require a weekday afternoon, silence after the deposit clears: those aren't quirks of the trade, they're the trade offloading its inefficiency onto you. We built the roofing company around fixing that for Bay Area homeowners.
Plenty of roofing contractors in the San Jose area do one piece of this. Someone flies a drone. Someone sends a couple of photos. What's rare is the whole chain: an online price first, a stated accuracy level, drone and satellite confirmation, a virtual consultation on your calendar, a photo-documented build, and one named point of contact from the first message to the final report. That chain is the Symplify Difference, and it's the part that survives contact with a real project.
"I got burned by a low bid once." Most people who tell us that were comparing two numbers attached to two different scopes. The low number usually assumed no decking replacement, an overlay instead of a tear off, or no permit at all. We write the scope out so the comparison is honest, even when it makes our number the higher one.
"They'll go quiet after I sign." You get a named contact, scheduled updates at each stage, and photographs as the work happens, including the deck once the old roof is off. If something changes up there, you see it in a photo before you see it on an invoice.

Want to walk your roof with us without taking a day off? Request a Virtual Estimate and we'll meet you on video.
Five steps take you from first contact to a final photo report, and you receive something concrete at each one.
1. Instant online estimate. Enter your San Jose, CA address and get a price range starting point in minutes, no phone tag, no sales visit first. Our instant online estimates are 95% accurate, and generally only require a short drone visit to confirm a final price. Start with the instant quote tool whenever it suits you, including at 11pm.
2. Virtual consultation on your schedule. If you'd rather not spend a weekday afternoon waiting for a truck, don't. We'll do the consultation by video or phone, go through your options, and answer the questions you didn't know to ask. Nobody at Symplify is trained to push. Our estimators are trained to explain.
3. Drone and satellite confirmation, plus a written scope. We confirm measurements from satellite imagery and a short drone visit, then send you a written scope covering the roof system, the deck condition we can see, flashing details, ventilation and cleanup. This is the document you should use to compare us to any other Bay Area roofing company you're considering, and it is the one part of the process the older roofing contractors in this market almost never hand over.
4. We pull the San Jose permit. Reroof permits are available through SJPermits for single-family, duplex, multifamily, commercial and industrial properties, and we handle that submission and the inspection scheduling. Most roof replacements take 2 to 3 days. Larger or more complex roofs can take longer. What shifts a calendar in San Jose is usually what happens before installation, not the installation itself: permit routing, historic review, structural justification, hidden deck damage, or solar equipment, since altering, replacing or removing solar or other rooftop equipment during a reroof can require additional electrical or mechanical permits.
5. Photo-documented roof installation, inspection, cleanup and warranty. Your crew documents the tear-off, the exposed deck, the underlayment and flashing, and the finished roof. We meet the City inspector, clear the site, sweep for nails, and register your warranty in your name. Your named contact stays the same person the whole way through.
This is the part that separates a roofing company that works here from one that only advertises here.
Permits, inspections and building codes. San Jose reroof permits are issued by the City of San José Planning, Building and Code Enforcement Department, Building Division, and the Development Services Permit Center sits in City Hall at 200 E. Santa Clara St. San Jose is the largest city in Santa Clara County, and its permit process is its own animal, which is one reason bids from roofing contractors who mostly work elsewhere in the Bay Area can miss a step. A building permit is required when 25% or more of a roof is reroofed within a 12-month period; below that threshold the City treats the work as a repair. Your permit card lists the inspections your project needs, and the inspector is checking the details the adopted building codes care about: fastener depth and installation, flashing and counter-flashing, sheathing, existing overlays, roof covering weight, minimum slope, fire rating, flue clearances, and underlayment installed per manufacturer instructions. We pull the permit, we schedule the inspection, and we're there for it. For the broader California rules that apply beyond San Jose, see our California roofing regulations guide.
Older and historic San Jose homes. Downtown San Jose and the blocks around it carry housing stock that needs a closer look before any roofing company quotes it. North Willow Glen lies south of I-280 between the Guadalupe River, Willow Street and Bird Avenue, and is mostly small-lot residential property developed during the first half of the 20th century. Naglee Park, bounded by East Santa Clara Street, South 11th Street, Coyote Creek and East William Street, is known for early-20th-century homes including bungalows and Spanish Colonial Revival residences. Market-Almaden holds late-19th- and early-20th-century Victorians and Craftsman bungalows near the Downtown core. A property on the Historic Resources Inventory requires Planning clearance before a reroof permit can be issued, and a City Landmark or a property in a City Landmark District requires a Historic Preservation Permit. The City's guidance also says replacement roof materials should be similar in scale, color and texture to historical materials, and it identifies black and dark gray as inappropriate in that review context, which is a detail worth knowing before you fall in love with a shingle sample. We confirm inventory status by address rather than assuming it by neighborhood, because the line runs parcel by parcel.
Roof weight, tile and hillside properties. Switching roofing materials in San Jose, CA is a structural question as much as a style question. The City requires structural justification if the completed roofing assembly exceeds seven pounds per square foot, which is exactly the conversation to have before, not after, you've chosen heavier tile. San Jose also maps Wildland-Urban Interface areas, and WUI properties do not qualify for some expedited reroof permit pathways. The same applies to the Los Gatos roofing work our crews handle on the western edge of the valley, where hillside access and fire-rated assemblies shape the plan from day one. If your address falls in one of those categories, the project isn't harder to build, it just needs a longer runway. We tell you that up front instead of discovering it at submission.
Climate, scheduling, and how we serve San Jose from Walnut Creek. San Jose's Mediterranean climate concentrates the weather risk into a handful of winter months, and like much of the Bay Area, that pattern means your roof ages under sun and then gets tested all at once. With NOAA's San Jose station showing a 16.14 inch annual normal and almost nothing falling in July and August, the dry stretch from late spring into early fall is the widest scheduling window most homeowners get. The first real autumn rain is when failed flashing announces itself, and it announces itself on the ceiling. Our office is in Walnut Creek, roughly 45 miles up I-680 from San Jose, and we're upfront that we don't have a San Jose storefront. What we do have is a process built so that distance costs us windshield time instead of costing you workdays: online roofing estimates, satellite measurement, video consultations, and one short drone visit rather than three appointments. We serve Alameda County (East Bay), Contra Costa County (East Bay), Marin County (North Bay), Napa County (North Bay), San Francisco County (The City), San Mateo County (The Peninsula), Santa Clara County (South Bay), Solano County (North Bay), Sonoma County (North Bay). Santa Cruz County sits just over the hill on Highway 17, and we'd rather tell you our footprint stops at those nine Bay Area counties than stretch the map to win a job. We are a Northern California company by design, we don't chase work in Orange County or anywhere else down south, and that concentration is why a San Jose, CA crew and a Concord crew build to the same written standard.
A building permit is required in San Jose once 25% or more of the roof is reroofed within a 12-month period. Work affecting less than 25% within that window is treated by the City as a repair and does not require a reroof permit. Because the clock runs over 12 months, a series of small roof repairs can add up and cross the line. We confirm which side your project falls on before any work starts, and we pull the permit when one is needed.
There is no honest citywide average, and any roofing company quoting you one over the phone is guessing. Price follows roof area, pitch, the number of existing layers, decking condition, material, access and complexity, and those vary enormously between two houses on the same street. That's the reason we built an online estimate instead of publishing a range. Start with the instant quote tool and you'll have a real starting number for your actual roof.
Our instant online estimates are 95% accurate, and generally only require a short drone visit to confirm a final price. That's possible because the tool works from satellite imagery of your specific roof rather than a neighborhood average, and because the drone visit closes the gap on the things imagery can't show, like the condition of flashing and the number of existing layers. You'll have a written scope alongside the number, which is what makes roofing estimates comparable between companies in the first place.
Bigger homes are where phone quotes go wrong most often, because the square footage of the house is not the same as the area of the roof. Pitch, dormers, valleys, multiple slopes and additions can add substantial surface area that no one can estimate from a floor plan. We measure from satellite imagery and confirm with a drone flight, so the number reflects the roof rather than the listing. Run your address through the instant estimate and we'll confirm from there.
Both. We do targeted roof repairs on flashing, valleys, pipe boots, skylights and isolated low-slope sections, and we do full roof replacements when the assembly has reached the end of its life. What we won't do is sell you the second when the first will hold. If the drone photos show a roof with years left and one bad detail, that's what the report will say.
Judge San Jose roofing contractors on things you can verify rather than on slogans: an active CSLB license, current insurance, manufacturer certification, warranty eligibility stated in writing, a documented permit and inspection process, and a named point of contact you can reach after you sign. Against that checklist, Symplify holds CA CSLB License #1108246, Owens Corning Platinum Preferred status, Diamond Certified status since April 2025 (CERT 2862), and a BBB profile. Ask every roofing company you're considering for the same five items, including us. The best roofing company for your project is simply the San Jose roofing company that can hand you all five without hedging.
We pull the San Jose permit and coordinate the City inspection; you don't file anything. Most roof replacements take 2 to 3 days. Larger or more complex roofs can take longer. Reroof permits run through SJPermits for single-family, duplex, multifamily, commercial and industrial properties. Where solar equipment or historic review is involved, that affects the calendar ahead of installation rather than the days your crew is on the roof.
Yes. We cover San Jose zip codes across the whole city and the rest of Santa Clara County, plus the other eight Bay Area counties. If you're searching for roofing companies near me from Willow Glen, Naglee Park, Berryessa, Evergreen, Almaden Valley or anywhere else in the San Jose area, you're inside our footprint, and so are Los Gatos roofing projects and the neighboring South Bay communities. We also work north and west of here, from San Mateo County on the Peninsula up through Alameda, Contra Costa, Marin, Napa, San Francisco, Solano and Sonoma counties, so a landlord with a duplex in San Jose and a fourplex in San Mateo County gets one roofing company and one point of contact instead of juggling two sets of roofing contractors.
Three easy ways to start, whichever suits you. Run your address through the instant online quote, call us at (844) 796-5439, or send a note through our contact page. Free roof estimates are the industry's standard promise among San Jose roofing contractors; ours simply arrives before anyone has to visit. Still weighing repair against replacement? The 30-second quiz is the shortest path to an answer.
One practical note on timing: San Jose's climate loads the dry-weather calendar early, and those dates fill across the Bay Area before the first real rain, so earlier conversations get better slots for Los Gatos roofing work and San Jose roofing projects alike. An estimate is a tool for your decision, not a commitment to us.
Our office is at 2815 Mitchell Dr, Ste 225 in Walnut Creek, about 45 miles up I-680, and our San Jose roofers are in the city regularly. Innovation, Simplicity, Excellence: that's the whole plan, and your roof in San Jose, CA is where we prove it.
