Call (877) 367-1429 any time, day or night - a live person answers, never a machine.
Why Napa Homes Are Different
Napa sits in a pressure cooker of its own making. The marine layer that cools coastal Marin rarely pushes past the Mayacamas, leaving our valley to bake under inland sun that regularly tops 100°F from June through September. That UV intensity strips granules from asphalt shingles far faster than in coastal zones just thirty miles away. Then the Mediterranean wet season arrives, concentrating roughly 25-30 inches of rain into November through April. Shingles already thinned by summer heat absorb that moisture, swell, and contract through freeze-thaw cycles that coastal roofs barely experience.
The August 2014 South Napa earthquake cracked chimney caps, shifted roof decks, and blew out flashing across entire neighborhoods simultaneously - damage we still uncover on homes whose owners never connected their current leaks to the quake. Downtown’s 94559 core holds Victorians and Craftsman bungalows built between the 1880s and 1920s, many with original steep pitches and multiple roofing layers hiding deteriorated skip-sheathing. Valley-floor tracts in 94558 are dominated by 1950s-1970s ranch homes with low-slope designs where failed pipe-boot flashings and worn 3-tab shingles are routine. And hillside neighborhoods above the valley floor fall under Cal Fire’s Very High Fire Hazard Severity Zone, making Class A fire-rated assemblies essentially mandatory on re-roofing permits.
Roof Repair in Napa
Most of our Napa repair calls trace back to three forces: earthquake legacy, thermal cycling, and concentrated winter rain. The 2014 quake displaced underlayment and cracked chimney counter-flashing that still lets water in a decade later. Summer heat exceeding 100°F bakes shingles brittle, then winter storms find the cracks. We carry common repair materials on every truck so most jobs finish in a single visit, and we photo-document every inspection from your actual roof - not the driveway. Roof Repair is our most called-for service in Napa, and we’ve built our stock and crew training around the problems this valley creates.
Flashing Repair
Flashing fails first on Napa roofs, and for different reasons depending on where you live. In hillside neighborhoods under Cal Fire’s Very High Fire Hazard Severity Zone, the 2014 earthquake shifted chimney counter-flashing and cracked masonry caps in ways that still admit water. On 1950s-1970s ranch homes in 94558, extreme thermal cycling between 100°F summers and rainy winters causes metal flashing to expand, contract, and separate from decking. Chimney flashing repair typically runs $450-$950, and post-earthquake chimney cap and flashing rebuilds range $800-$1,800.
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 interior damage back to its source - often finding earthquake-displaced underlayment from 2014 that the homeowner never connected to their current problem. Most minor leak repairs run $250-$550. Our crews work wet or dry, and the number on our estimate is the number on your invoice.
Can the 2014 earthquake still be causing my roof to leak?
Yes - the M6.0 South Napa earthquake cracked chimney caps, shifted roof decks, and displaced underlayment across entire neighborhoods, much of it invisible 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 or drafts, call (877) 367-1429 for a free inspection.
Roof Replacement & Installation in Napa
A full roof replacement in Napa typically runs $12,000-$28,000 for residential homes, with most asphalt shingle jobs completed in 2-3 days during dry weather. Our crews serve Napa from our San Francisco Bay Area office, close enough to reach the valley within the hour. We carry Class A fire-rated materials for hillside properties and stock GAF and CertainTeed architectural shingles rated for the inland UV that granule-strips lesser products in eight to ten years. Roof Replacement & Installation estimates are free and include full tear-off inspection for hidden earthquake damage.
Asphalt Shingle Replacement
Asphalt remains the practical choice for most Napa valley-floor homes, but the wet-then-bake cycle here is brutal on cheap shingles. We install GAF and CertainTeed architectural lines rated for the inland UV exposure that destroys standard products. In 94558 tract neighborhoods, we regularly find 20-year-old 3-tab shingles cooked to bare fiberglass - replacement with proper architectural shingles typically costs $12,000-$18,000 for a 2,000-square-foot home.
Tile Roofing
Clay and concrete tile suit Napa’s Mediterranean aesthetic and perform well in our climate, but tile roofs are heavy and unforgiving of deck movement. The 2014 earthquake shifted substrate framing on hillside homes that owners never realized was compromised. We inspect the deck thoroughly before setting new tile, and we carry Boral products that match the Spanish Colonial profiles common in older neighborhoods. Tile replacement typically runs $22,000-$35,000.
Do I need a Class A fire-rated roof for my hillside property in Napa?
Yes. Hillside neighborhoods above the valley floor fall under Cal Fire’s Very High Fire Hazard Severity Zone, and re-roofing permits in these areas require Class A fire-rated assemblies. We specify rated shingles, tile, or metal on every Napa hills estimate and carry documentation to satisfy inspection. Unsure if your property is in the zone? Call (877) 367-1429 and we’ll check during your free estimate.
Specialty Roofing in Napa
Specialty roofing in Napa, CA typically costs between $8,500 and $28,000 depending on system type, with most commercial low-slope jobs running $12-$18 per square foot. The valley’s wine industry generates a roofing niche that pure residential shops in Sonoma or Marin rarely need: barrel rooms, crush pads, and tasting-room pavilions throughout the 94558 and 94559 zip codes require large-span low-slope expertise in modified bitumen, TPO, and standing-seam metal. Specialty Roofing crews carry both residential and light commercial training, and we specify stainless-steel fastening hardware to resist the salt-air corrosion that pushes through the Carquinez Strait.
TPO Roofing
TPO single-ply membrane has become the workhorse for Napa’s commercial and agricultural buildings. The white reflective surface cuts cooling loads during July and August stretches when valley temperatures spike past 105°F. For winery barrel rooms and crush pads, we specify GAF EverGuard TPO with stainless-steel fastening plates. TPO installation in Napa typically runs $12-$16 per square foot.
Modified Bitumen Roofing
Modified bitumen remains the trusted choice for low-slope winery buildings and commercial flat roofs throughout Napa Valley. The APP-modified sheets handle thermal cycling better than built-up roofing in our climate, and torch-applied or self-adhered seams create a monolithic barrier against concentrated winter rains. We see aging mod-bit on tasting-room pavilions along Highway 29 and the Silverado Trail - replacement with modern systems typically runs $10-$15 per square foot.
Does my hillside Napa home need Class A fire-rated specialty roofing?
Probably, if you’re above the valley floor - Cal Fire maps classify most hillside neighborhoods in Napa as Very High Fire Hazard Severity Zone, making Class A fire-rated assemblies essentially mandatory on re-roofing permits. This code reality shapes nearly every specialty roofing estimate we write in 94558 and 94559 zip codes. We handle the compliance documentation as part of our standard process. Call (877) 367-1429 for specifics on your property.
Gutters & Accessories in Napa
Gutter installation and repair in Napa typically runs $1,200-$3,800 for most residential jobs, with same-week scheduling available throughout the 94558, 94559, and 94581 zip codes. Napa’s acreage properties, detached workshops, and valley-oak canopies demand heavier-duty systems than standard suburban installations. The combination of heavy debris from valley oaks and eucalyptus, longer roof runs on outbuildings, and intense winter rain overwhelms lighter 5-inch gutters. Gutters & Accessories work includes seamless gutter formation on-site, gutter guard systems, and fascia repair - all with upfront pricing and our 90-Day Done Right Promise.
Seamless Gutter Installation
On Napa’s acreage properties, standard 5-inch gutters often fail. We install 6-inch seamless gutters formed on-site to exact length, eliminating leak-prone seams. For a workshop off Hagen Road in 94558, we replaced a failed 5-inch K-style with 6-inch seamless, heavy-duty hidden hangers, and dedicated 4-inch downspouts to underground drains. Seamless gutters in Napa typically run $8-$14 per linear foot installed.
Gutter Guard Systems
Napa’s Mediterranean climate creates a unique debris cycle: winter rains pack oak leaves and eucalyptus bark into gutters, then summer heat bakes the residue into a dense mat. We install proven systems that handle heavy organic load without creating damming at the roof edge. Gutter guard installation generally costs $6-$12 per linear foot, or $900-$2,200 for a typical home. For properties under heavy canopy cover, we recommend micro-mesh over foam inserts.
Why do gutters on my Napa acreage property need larger downspouts?
Valley oaks and eucalyptus drop debris that standard 2×3-inch downspouts cannot pass, causing backup and overflow during November-through-April rains. We install 3×4-inch or 4-inch round downspouts on Napa acreage properties as standard practice, not an upgrade. Call (877) 367-1429 and we’ll size your system for the actual debris load your property sees.
Emergency & Storm Damage in Napa
When a winter storm tears through Napa, you don’t have time to wait on a contractor from Sacramento or a voicemail tree that sends you in circles. Our phones are answered by a live person 24 hours a day, including nights, weekends, and the middle of a storm. We carry emergency tarps, GAF WeatherWatch leak barrier, and specialized flashing stock to handle the earthquake-legacy damage that still fails when rain hits. Emergency & Storm Damage response includes full photo documentation for your insurance file.
Storm Damage Repair
Napa’s climate delivers punishment in two acts: five months of concentrated winter rain, then months of 100°F-plus dry heat that cooks whatever the rain compromised. We see the results every November - granule-stripped shingles on valley-floor ranches, lifted flashing on hillside homes, and hidden earthquake damage the 2014 quake left behind. Wind damage repair typically runs $450-$1,200, and partial roof repair runs $450-$750 per square.
Emergency Tarp
When a redwood limb comes down on a roof off Coombsville Road or wind peels back a ridge cap on a Trancas Street ranch, water doesn’t wait for business hours. Our emergency tarp service runs around the clock because we’ve seen what forty-eight hours of unprotected decking does to a home’s interior. We use anchored, weighted tarp systems that won’t turn into sails in the next gust. A typical emergency tarp in Napa costs $350-$650.
How long can I wait before repairing a leaking chimney cap in Napa’s wet-dry cycle?
Not past the next rain. Napa’s concentrated winter wet season delivers nearly all annual rainfall in sustained storms, and even a small chimney leak in October becomes saturated decking, mold, and interior damage by January. Summer bakes compromised mortar and flashing, making the next failure worse. If your chimney cap is cracked or flashing is lifting, call (877) 367-1429 now - emergency tarp buys time, but permanent repair is the only fix.

What Napa Customers Say
"Added a ridge vent and cleared the blocked soffit vents. The attic temperature dropped noticeably and the upstairs is livable in summer now."
- Simone Grant"Three cracked tiles and one that had slipped. Matched the tile, no color mismatch, half a day of work."
- Darius Prince"The flashing where the roof meets the chimney had never been done right by the original builder. He rebuilt it with proper step flashing instead of running a bead of caulk over it like the last two people did."
- Maurice Boyd
