Fast, Reliable Roof Repair Across Napa
Roof repair in Napa typically runs $250-$1,800 depending on scope, and our crews can usually be on your roof within 24 hours of your call. We know the difference between a valley-floor ranch in 94558 and a steep-pitch Victorian off First Street in 94559, and we bring the right materials and the right crew for whichever roof you’ve got. Call (877) 367-1429 any time, day or night - a live person answers, never a machine.
We’ve been climbing Napa roofs since 1984. That means we’ve seen what the 2014 earthquake left behind, what the valley’s wet-then-bake summers do to shingles, and why a flashing job in the hills above Silverado Trail isn’t the same as one on the flatlands near the Napa River. Our Roof Repair team doesn’t guess. We inspect, photograph what we find, and tell you exactly what needs fixing and what doesn’t.

Our Roof Repair Services in Napa
Flashing Repair
Flashing is where most Napa roofs fail first, and for three different reasons depending on where you live. In the hillside neighborhoods above the valley floor - areas that fall under Cal Fire’s Very High Fire Hazard Severity Zone - the 2014 South Napa earthquake shifted chimney counter-flashing and cracked masonry caps in ways that still let water in a decade later. On the 1950s-1970s ranch homes in 94558, extreme thermal cycling between 100°F summers and rainy winters causes metal flashing to expand, contract, and eventually separate from the decking. And in downtown 94559, multiple layers of old roofing on Victorian and Craftsman homes often bury original flashing under generations of patchwork. We remove it all, install new step flashing and counter-flashing to code, and seal it with proper underlayment - not caulk over the problem.
Leak Repair
A leak never comes from nowhere. In Napa’s Mediterranean climate, with 25-30 inches of rain packed into November through April, a small entry point becomes a ceiling stain fast. We trace the water path from the interior damage back to its source - often finding earthquake-displaced underlayment from 2014 that the homeowner never connected to their current problem. Our crews work wet or dry, and we carry common repair materials so most leak repairs finish in a single visit. The number on our estimate is the number on your invoice.
Shingle Replacement
Napa’s inland UV is brutal on asphalt shingles. While coastal Bay Area cities 30 miles southwest stay moderated by marine layer, our valley regularly exceeds 100°F for prolonged stretches. That heat bakes shingles, accelerates granule loss, and turns 3-tab products brittle long before their rated lifespan. We replaced a low-slope ranch roof on a 1950s home in Napa’s 94558 valley floor near the Napa River where 30 years of wet-dry cycling had turned the 3-tab shingles brittle and caused granule loss. Our crew stripped two layers, replaced deteriorated pipe-boot flashings with Owens Corning boots, and applied a full GAF Timberline HDZ shingle system, ensuring tight seals against the November rains. We match existing shingles where possible, or recommend full-system replacement when patching would be throwing good money after bad.
Flat Roof Patch
Flat and low-slope roofs in Napa serve a niche most neighboring counties don’t have: winery barrel rooms, crush pads, and tasting-room pavilions throughout the valley require Specialty Roofing in Napa - modified bitumen, TPO, standing-seam metal. Residential ranch homes in 94558 also carry low-slope sections over garages and additions. We patch with materials rated for the application, not whatever’s in the truck. Proper slope, proper drainage, proper membrane - done right, and if it’s not, we make it right.

Trusted Brands We Service in Napa
We stock repair materials from GAF, CertainTeed, and Owens Corning - three of the seven manufacturer lines we’re authorized to install - so Napa customers aren’t waiting on a parts run to Sacramento. For a typical shingle repair, that means same-day completion. For flashing and underlayment work, we carry ice-and-water shield, synthetic felt, and proper vent boots in our Napa-area warehouse, not on a “we’ll come back next week” basis. We don’t substitute materials without telling you. The brand specified is the brand installed.
Common Roof Repair Problems We See in Napa Homes
- Cracked chimney caps and shifted roof decks from the 2014 South Napa earthquake. The M6.0 event was the Bay Area’s largest since 1989 Loma Prieta, and it damaged roofing assemblies across entire neighborhoods simultaneously. We still find earthquake-displaced underlayment and failed chimney counter-flashing on homes whose owners never connected the damage to the quake - often not until a leak appears years later.
- Failed pipe-boot flashings on 1950s-1970s ranch homes in 94558. The extreme thermal cycling between 100°F summers and rainy winters causes rubber and neoprene boots to crack and separate. It’s one of the most common calls we get from the valley-floor tracts, and it’s preventable with proper replacement before the November rains start.
- Worn underlayment on steep-pitch Victorians in downtown 94559. Many of these homes carry multiple layers of previous roofing, and local codes require full tear-off before re-roofing. The original underlayment, often felt saturated with decades of trapped moisture, fails at the valleys and eaves first.
- Granule loss and brittle shingles from Napa’s intense inland UV. Unlike coastal cities, our valley sees prolonged dry heat that bakes asphalt shingles far beyond their design stress. We regularly find 20-year shingles failing at 12-15 years on south- and west-facing slopes.

FAQs - Roof Repair in Napa
Yes - the M6.0 South Napa earthquake cracked chimney caps, shifted roof decks, and displaced underlayment across entire neighborhoods, and much of that damage was not visible from the ground. We regularly find failed chimney counter-flashing and separated underlayment on homes whose owners never connected their current leaks to the 2014 event. If your home was built before 2014 and you’ve noticed new staining, drafts, or mortar cracking at the chimney, call (877) 367-1429 for a free inspection - we’ll photograph what we find and show you exactly what’s happening.
For any re-roofing permit in Cal Fire’s Very High Fire Hazard Severity Zone - which includes hillside neighborhoods above the Napa valley floor - Class A fire-rated roofing assemblies are essentially mandatory, and this requirement shapes nearly every estimate we write in those zip codes. A minor repair may not trigger full re-roofing requirements, but if your repair involves significant decking or underlayment replacement, the code compliance path matters. We handle the permit research and specify compliant materials upfront so there are no surprises at inspection. Call us to review your specific location and scope.
The 1950s-1970s ranch homes in 94558 experience extreme thermal cycling: 100°F-plus summer days cause rubber and neoprene boots to expand and degrade, then winter rain finds the cracks. We also install and repair Gutters & Accessories in Napa to manage that runoff. Napa’s inland UV is far more aggressive than coastal Bay Area cities just 30 miles southwest where marine layer moderates temperatures. We replace failed boots with Owens Corning or CertainTeed vent boots rated for this climate, properly flashed and sealed - not the hardware-store generic that’ll crack again in three years. Most pipe-boot replacements run $180-$340 and finish in under two hours.
Often yes, if the damage is localized and the existing roofing layers haven’t exceeded code limits - downtown 94559 Victorians and Craftsman bungalows frequently carry multiple old layers that must be torn off before re-roofing per local requirements. We repair isolated shingle damage, valley leaks, and flashing failures on steep pitches up to 12:12, matching existing materials where possible. Our photo-documented inspection will tell you whether repair or full replacement is the square deal. Estimates are free - call (877) 367-1429.
Yes - the valley’s wine industry generates a commercial roofing niche that pure residential shops in Sonoma or Marin rarely see. Barrel rooms, crush pads, and tasting-room pavilions require large-span low-slope expertise in modified bitumen, TPO, and standing-seam metal. Our crews are trained and equipped for both residential and light commercial flat roof repair throughout the Napa Valley floor. We specify the right membrane for the application, ensure proper drainage, and back it with our 90-Day Done Right Promise. Call for a free assessment of your facility’s roof condition.
