Short answer: As of September 2026, the five highest-scoring roofing contractors in the San Jose-Sunnyvale-Santa Clara, CA metro on The Roofing Brief Contractor Score are Master Craft Roofing (91.1), Roofs By Reveille, Inc. (84.8), Indaspec Smart Roofing, HVAC & Energy Solutions (82.4), ACME Roofing Services, Inc. (81.0), First Tier Exterior Inc (78.6). Every one holds a manufacturer certification that can be verified independently, every rating below has been corroborated against at least one source outside the certification registry, and no company paid to appear here.
The Roofing Brief scored 12 certified roofing contractors serving the San Jose metro on a published, reproducible formula, then researched each of the top five individually to confirm its record. San Jose recorded zero damaging hail in the past decade, the cleanest reading of any metro published so far. Roofs here fail from ultraviolet exposure and thermal cycling, not impact, so material choice and underlayment quality decide lifespan. California requires a Contractors State License Board licence under the C-39 classification for any roofing job over $500, backed by a trade exam, a law and business exam and four years of documented journey-level experience. Note that three of the five below also rank in our San Francisco list, because the Bay Area’s certified contractors genuinely work across both metros.

Why a San Jose roof fails slowly rather than suddenly
Silicon Valley has almost no severe weather: 35 hail reports over the decade, none reaching an inch, six severe wind reports and two weak tornadoes. The strongest gusts in the record are ridge-top readings, 90 mph on Mount Umunhum in December 2025. Nothing here justifies impact-rated shingles or a storm-damage inspection pitch. What does matter is water: winter storms arrive as sustained rain driven by wind, and the flashing, valley and penetration details are where a Bay Area roof leaks.
The energy code does bind here, which surprises people who assume the coast is exempt. For a re-roof, the prescriptive cool roof requirement for steep-slope single-family roofs covers Climate Zones 4 and 8 to 15, and San Jose sits in Zone 4. The code allows equivalent alternatives rather than a reflective shingle, including a ceiling assembly insulated to R-38 or better, a radiant barrier in the attic, having no ducts in the attic, or continuous insulation above or below the deck. Ask which compliance path the contractor intends to use, because it changes the product and the paperwork.
San Jose’s permit rule is a simple percentage: a permit is required when 25 per cent or more of the roof is re-roofed in any twelve-month period, and anything less is treated as a repair. That gives an unscrupulous contractor an obvious temptation to describe a replacement as a series of repairs. Insist on the permit when the work crosses that line, and ask for the number. In the hills of Santa Clara County, wildland-urban interface rules add a Class A assembly requirement, which is address-specific and worth confirming before you choose a covering.
California licenses roofing as Class C-39, requiring four years of journey-level experience and two examinations, and the CSLB record shows bond, workers’ compensation and any disciplinary action. In one of the most expensive housing markets in the country, the financial protections are worth knowing too: the down payment on a home improvement contract may not exceed $1,000 or 10 per cent of the price, whichever is less, and progress payments should follow completed work.

What they actually do. Residential roofing across San Jose and the South Bay.
Services we could verify: roof repair.
Why it ranks here. Holds a plumbing classification alongside roofing. Plumbing vent penetrations are among the most common leak points on a re-roofed deck, and a contractor licensed for both can correct a failing vent rather than flash around it.
Best fit for: Roofs where plumbing vent penetrations are the suspected leak source.
What we would want clarified. At 35 registry reviews this is the thinnest evidence base in the San Jose top five, so the volume-adjusted rating sits well below the raw score. We publish this because a ranking that only prints the flattering findings is an advertisement, not an assessment.

What they actually do. Roofing alongside solar, battery storage, whole-home generators, EV charger installation and HVAC.
Services we could verify: roof replacement.
Why it ranks here. Holds both an electrical and a roofing classification, which is the combination required to install solar properly rather than subcontract it. In a market where a large share of re-roofs involve removing and resetting existing solar, that matters more here than in most metros.
Best fit for: Homes with existing solar that must be removed and reset during a re-roof.

Roof replacement and repair in San Jose, CA
Short answer: For a San Jose roof, Master Craft Roofing suits leaks traced to plumbing vents, Roofs By Reveille suits Santa Clara County homeowners, Indaspec suits homes with solar to remove and reset, ACME Roofing Services covers Morgan Hill and Gilroy, and First Tier Exterior suits UV-focused replacements. The key local rule: San Jose requires a permit when 25 per cent or more of the roof is re-roofed in any twelve-month period.
San Jose roofs rarely fail from impact. Silicon Valley logged 35 hail reports over the decade, none reaching an inch and the largest 0.75 inch, plus six severe wind reports and two weak tornadoes. The strongest gust on record, 90 mph on Mount Umunhum in December 2025, was a ridge-top reading. Nothing here justifies impact-rated shingles. Replacement is usually driven by ultraviolet exposure and thermal cycling, so material choice and underlayment quality decide lifespan. Repairs are usually about water: winter storms bring sustained, wind-driven rain, and flashing, valley and penetration details are where a Bay Area roof leaks.
San Jose requires a permit when 25 per cent or more of the roof is re-roofed in any twelve-month period; anything less is treated as a repair, which tempts some contractors to describe a replacement as a series of repairs. Ask for the permit number. Statewide, any replacement roof must be torn off to the deck (CRC R908.3), so an overlay is not an option. Replacing more than 50 percent in a year outside fire hazard severity zones requires at least a Class C covering, and in Wildland-Urban Interface areas, including the hills of Santa Clara County, the roof must meet new-construction Class A standards. San Jose sits in Climate Zone 4, where the cool roof requirement applies unless an equivalent path such as R-38 ceiling insulation or an attic radiant barrier is used.
California regulations require that, under replacement cost policies, when replaced items do not match in quality, color or size, the insurer replace all items in the damaged area to a reasonably uniform appearance (Cal. Code Regs. tit. 10, section 2695.9(a)(2)). On the contract side, the down payment on a home improvement contract may not exceed $1,000 or 10 per cent of the price, whichever is less, and progress payments should follow completed work. A Contractors State License Board licence is needed for any job of $1,000 or more, and a stand-alone reroof needs a C-39 roofing licence or a licensed roofing subcontractor.
For leaks, Master Craft Roofing holds roofing and plumbing licences and can correct a failing plumbing vent rather than flash around it. Indaspec holds electrical and roofing classifications and suits re-roofs where existing solar must be removed and reset. First Tier Exterior focuses on roof replacement, is also CertainTeed and Malarkey certified, and states it uses in-house crews with no subcontracting, with Malarkey’s polymer-modified asphalt marketed for UV and heat resistance. Roofs By Reveille holds a 5.0 rating across 74 reviews for Santa Clara County homeowners, and ACME Roofing Services handles residential and commercial roofing in Morgan Hill, Gilroy and southern Santa Clara County.

8 severe weather reports in a decade, and why that matters in San Jose
Aggregate hail counts tell you very little about a specific roof. These are the individual events: every severe-weather report logged by the National Weather Service across the 2 counties of the San Jose-Sunnyvale-Santa Clara, CA statistical area over ten years, with the dates, the stone sizes and the towns they landed on. Over that decade the metro logged 35 hail reports, 6 severe thunderstorm and high wind reports and 2 tornadoes. Reported property damage from hail, severe wind and tornado over that decade totalled $10.0 million; flood and winter-storm losses are counted separately and are not included.
The biggest hail to fall on San Jose in a decade
| Date | Stone size | Reported near | County |
|---|---|---|---|
| 6 April 2020 | 0.75 in | Evergreen | Santa Clara |
| 25 January 2018 | 0.75 in | Gilroy | Santa Clara |
| 25 March 2020 | 0.38 in | Los Gatos | Santa Clara |
| 25 March 2020 | 0.35 in | Mountain View | Santa Clara |
| 2 March 2018 | 0.25 in | San Jose | Santa Clara |
| 5 March 2017 | 0.25 in | Los Gatos | Santa Clara |
The largest stone on record for this metro fell on 6 April 2020 near Evergreen, measured at 0.75 inches. That is below the size at which hail normally damages a shingle roof.
Wind. The strongest thunderstorm gust logged in the metro was 78 knots, about 90 mph, near Holy City on 25 December 2025. Asphalt shingles begin lifting at roughly 67 mph when they are correctly nailed, and considerably below that when they are not.
Tornadoes. 2 tornadoes touched down in these counties over the decade, the strongest rated EF0 near Dunneville Corners on 6 January 2016.
What the National Weather Service wrote about it
The NWS logs a written account of each severe-weather episode. This is its description of the 5 March 2017 event near Los Gatos, reproduced verbatim:
A cold front moved through the MTR CWA the night of Saturday March 4th producing steady rain and isolated thunderstorms into Sunday. This system resulted in minor roadway flooding, a debris flow, and pea sized hail.
A roof in this metro is built against events like that one, as recorded by the agency that recorded it rather than by a contractor selling the repair.
When it happens. Severe weather reports cluster in March (19), January (12), April (4). The worst years on record were 2020 (14), 2018 (11), 2017 (5). If you are scheduling non-urgent work in San Jose, the months outside that window are when crews are least stretched and least likely to be triaging emergency callouts ahead of your job.
Source: NOAA National Centers for Environmental Information, Storm Events Database, county-level detail files 2016 to 2025, filtered to the counties of this statistical area by The Roofing Brief. Damage figures are as reported to the NWS and undercount insured losses.
What to do with this. Hail is not the governing risk in San Jose. Weight your decision toward wind rating, ventilation and flashing detail rather than paying extra for impact-rated shingles.
Before you sign anything in San Jose
Licensing is required in CA. California requires a Contractors State License Board licence for any job where labour and materials combined reach $1,000 or more, a threshold raised from $500 by Assembly Bill 2622 on 1 January 2025. The exemption never covers a reroof: under Business and Professions Code 7048 it applies only to minor work under $1,000 that needs no building permit, and is lost if the person employs anyone or advertises as a contractor. Roofing is the C-39 classification. A B General Building contractor may include roofing in a multi-trade project, but a stand-alone reroof needs a C-39 licence or a licensed roofing subcontractor (B&P 7057).
A C-39 qualifier must document at least four years of journey-level experience and normally passes both a trade examination and a law and business examination unless a statutory waiver applies. Every active licence carries a $25,000 contractor’s bond, and C-39 roofing licensees must carry workers’ compensation whether or not they have employees: roofing is one of the few classifications that cannot file the no-employee exemption.
Check here: CSLB Check a License. The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
For what a full replacement costs across California, including state labor rates and permit rules, see our California roof replacement cost guide.
Four checks to run before you sign anything, in any state.
- Verify certification at the source. Use the GAF verification tool rather than trusting a badge image on a company website.
- Get the certificate of insurance from the insurer, not the contractor, and confirm general liability and workers compensation are both active on the day work starts.
- Confirm who pulls the permit. If a contractor asks you to pull it as the homeowner, that moves liability onto you. Decline.
- Get warranty terms in writing before any deposit, and check the manufacturer warranty being promised actually requires the certification tier the contractor holds.
The San Jose market behind this ranking
12 certified roofing contractors serve the principal cities of the San Jose-Sunnyvale-Santa Clara, CA statistical area, of which 2 hold the top President’s Club tier. The pool carries 672 customer reviews between them at a mean rating of 4.875. The statistical area had a 2024 population of 1,995,484, a change of -0.25% against the 2020 census base, per the U.S. Census Bureau Vintage 2024 estimates.
How these San Jose rankings were produced
Every contractor in the San Jose-Sunnyvale-Santa Clara, CA pool was scored out of 100 on four published components: certification tier, a Bayesian adjusted rating, review depth and distance from the metro centre. In this metro that meant scoring 12 certified contractors, of whom 2 hold President’s Club standing and 10 Master Elite, against a metro mean rating of 4.875. The top five were then researched individually against Better Business Bureau records, state licence registers and manufacturer directories. Where that research turned up something awkward it is on the page, and no placement was paid for.
The full method, the weightings, what the GAF certification tiers actually mean, who is eligible to be ranked and what we do not claim are all set out on our roofer ranking methodology page. Last updated: September 2026. Scoring run: 2026-09-15. Corrections go to the editor and are actioned on verification.
San Jose roofing questions, answered
Who is the best roofer in San Jose, CA?
Master Craft Roofing of San Jose, CA scores highest in the San Jose metro on The Roofing Brief Contractor Score, at 91.1 out of 100 as of September 2026. It holds President’s Club certification with a 4.9 rating across 35 reviews. Highest-scoring is not the same as best fit for your specific job, and the four companies behind it score within 12.5 points.
What is the 25% rule for roofing in California?
California has no 25 percent rule; its statewide trigger is 50 percent. Replacing more than 50 percent of roof area within one year requires at least a Class C covering outside fire hazard severity zones, and Class A new-construction standards inside Fire Hazard Severity Zones or WUI areas. Separately, San Jose’s own permit rule applies at 25 per cent or more re-roofed in any twelve-month period.
Do I need a permit to replace a roof in San Jose?
Yes, if 25 per cent or more of the roof is re-roofed in any twelve-month period; less is treated as a repair. Insist on the permit when work crosses that line and ask for the number. In the hills of Santa Clara County, wildland-urban interface rules may add a Class A requirement, which is address-specific.
Who does roof repair in San Jose?
Master Craft Roofing, based in San Jose, holds both roofing and plumbing licences and suits leaks where plumbing vent penetrations are the suspected source. In San Jose, leaks most often occur at flashing, valley and penetration details during wind-driven winter rain.
Can a roofer install new shingles over my old roof in California?
No. Under CRC R908.3, any replacement roof in California must be torn off to the deck. Many cities also adopt stricter local amendments, so check with your city or county building department.
How many certified roofing contractors serve San Jose?
12 contractors on the GAF certification registry serve the principal cities of the San Jose-Sunnyvale-Santa Clara, CA statistical area as of September 2026, of which 2 hold President’s Club status.
How much damaging hail does San Jose get?
The San Jose-Sunnyvale-Santa Clara, CA statistical area recorded 0 hail reports of 1 inch or larger and 0 of 2 inches or larger between 2016 and 2025 in the NOAA Storm Events Database. The largest hailstone reported measured 0.75 inches.
Did any contractor pay to appear on this list?
No. The Roofing Brief takes no placement fees, no lead fees and no affiliate commission from any roofing contractor. Ranking comes entirely from the published formula applied to public registry data, followed by an individual research pass on the top five.
What was the worst hailstorm in San Jose in the last ten years?
The largest hailstone logged by the National Weather Service in the San Jose-Sunnyvale-Santa Clara, CA statistical area between 2016 and 2025 measured 0.75 inches, reported near Evergreen on 6 April 2020. That is below the size at which hail normally damages a shingle roof. Across the decade the metro recorded 35 hail reports. Reported property damage from hail, severe wind and tornado over that decade totalled $10.0 million; flood and winter-storm losses are counted separately and are not included.
When is the worst time of year for roof damage in San Jose?
Severe-weather reports in the San Jose-Sunnyvale-Santa Clara, CA statistical area cluster in March, January, April, on the NOAA record for 2016 to 2025. Outside those months local crews are not triaging storm damage, so lead times are shorter and scheduling is easier.
Do roofers need a licence in CA?
California requires a Contractors State License Board licence for any job where labour and materials combined reach $1,000 or more, a threshold raised from $500 by Assembly Bill 2622 on 1 January 2025. The exemption never covers a reroof: under Business and Professions Code 7048 it applies only to minor work under $1,000 that needs no building permit, and is lost if the person employs anyone or advertises as a contractor. Roofing is the C-39 classification. A B General Building contractor may include roofing in a multi-trade project, but a stand-alone reroof needs a C-39 licence or a licensed roofing subcontractor (B&P 7057). A C-39 qualifier must document at least four years of journey-level experience and normally passes both a trade examination and a law and business examination unless a statutory waiver applies. Every active licence carries a $25,000 contractor’s bond, and C-39 roofing licensees must carry workers’ compensation whether or not they have employees: roofing is one of the few classifications that cannot file the no-employee exemption.
What should I check before hiring a roofer in San Jose?
The CSLB record also shows complaint and disciplinary history, including citations and accusations. Treat any status other than Active as disqualifying.
Is San Jose a hard market to find a good roofer in?
San Jose recorded zero damaging hail in the past decade, the cleanest reading of any metro published so far. Roofs here fail from ultraviolet exposure and thermal cycling, not impact, so material choice and underlayment quality decide lifespan. California requires a Contractors State License Board licence under the C-39 classification for any roofing job over $500, backed by a trade exam, a law and business exam and four years of documented journey-level experience. Note that three of the five below also rank in our San Francisco list, because the Bay Area’s certified contractors genuinely work across both metros.
Is wind or hail the bigger risk to a roof in San Jose?
Wind, by a wide margin. The San Jose-Sunnyvale-Santa Clara, CA statistical area logged 6 severe thunderstorm and high wind reports against 0 hail reports of an inch or more between 2016 and 2025. Wind damage shows up at the rake, ridge and edge rather than across the field of the roof, so the fastening schedule and edge detail matter more here than the impact rating of the shingle.
