Roofers in St. Helena, CA
Roofing in St. Helena, CA means working on homes that range from 1890s Victorians to modern wine-country estates, nearly all of them under Napa County’s wildfire safety codes. Most jobs here involve replacing aging wood shake with Class A fire-rated assemblies that still look right on a historic street. If you’re pricing a roof in St. Helena, expect the work to cost more than a typical suburban re-roof because of fire-resistant underlayments, ember-rated vents, and the care required around original trim and detailing. Call Brennan Roofing at (361) 320-9467 and we’ll put a written price in your hand before any work starts.
Why St. Helena Homes Are Different
St. Helena sits in the middle of Napa Valley, and the housing stock reflects a century and a half of building. Downtown has original Victorian-era farmhouses with redwood or cedar shingle roofs. The surrounding hills hold early 1900s bungalows and newer estates, many built to mimic older wine-country styles with clay tile or composite shingles. The common thread is fire. Much of St. Helena is wildland-urban interface, which means Napa County requires Class A fire-rated roof assemblies on most re-roofs. That includes ember-resistant ridge and eave vents, non-combustible underlayment, and careful flashing around every penetration. The 2020 Glass Fire pushed those requirements further, and any roofer working in St. Helena has to know the current code chapter and verse.
The climate adds another layer. Hot, dry summers bake roofing materials with intense UV exposure, while wet winters test flashing and drainage. High winds during fire season can carry embers a mile ahead of a flame front, so the smallest gap in a roof assembly is a real liability. Homes here are not interchangeable with tract housing in the Central Valley. A roofer who treats a St. Helena Victorian like a standard suburban split-level will miss the details that matter.
Our Main St. Helena Services
Most St. Helena homeowners call us for one of three things: a full roof replacement, a targeted repair, or an inspection before buying, selling, or heading into fire season. Each service has its own page with pricing and details.
Roofing Company in St. Helena
Full roof installation and replacement in St. Helena means tearing off the old material, inspecting the decking, and building a fire-rated assembly from the deck up. On historic homes, we often work with homeowners who want the fire performance of a modern system without losing the character of their original rooflines. We install materials from GAF, Atlas, and Boral, and we explain the trade-offs in plain language before you choose. See the full breakdown on our Roofing Company in St. Helena page.

Roof Repair in St. Helena
Roof repair in St. Helena usually comes down to three things: wind damage from fall and winter storms, leaks around old flashing, and ember-intrusion points discovered after a fire-season inspection. We replace damaged flashing, repair or replace underlayment at penetrations, and seal gaps that would let embers in. Repairs are priced in writing before work begins, and the 365-Day Done Right Promise applies. Details are on the Roof Repair in St. Helena page.

Roof Inspection in St. Helena
A roof inspection in St. Helena is not a drive-by glance. We walk the roof, check every flashing point, examine the underlayment at roof-to-wall intersections, and verify that vents meet current Napa County ember-resistance standards. Homeowners selling a property here often need documentation that the roof is fire-compliant, and buyers want the same before closing. The full process and what the report includes is on our Roof Inspection in St. Helena page.

Pricing for Roofers in St. Helena, CA
These are the price ranges we see most often for roofing work in St. Helena. Every job is different, so use these as a starting point, not a bid.
| Service | Typical range in St. Helena |
|---|---|
| Full roof replacement (asphalt shingle) | $12,000 – $22,000 |
| Full roof replacement (composite/synthetic shake) | $18,000 – $34,000 |
| Full roof replacement (clay or concrete tile) | $28,000 – $48,000 |
| Wood shake to Class A composite conversion | $20,000 – $38,000 |
| Roof repair (minor, flashing or shingle) | $350 – $800 |
| Roof repair (moderate, underlayment or decking) | $800 – $2,500 |
| Ember-resistant vent replacement (per vent) | $75 – $180 |
| Roof inspection (visual, written report) | $200 – $450 |
| Skylight replacement or re-flashing | $900 – $2,200 |
| Gutter replacement (seamless aluminum, per linear foot) | $9 – $16 |
Prices in St. Helena run higher than the state average for two reasons: fire-rated materials and labor. A Class A assembly adds cost to the underlayment, vents, and sometimes the decking itself. And historic homes rarely have a simple roofline, so crews move slower around dormers, cupolas, and original trim. What does not change is our pricing model: the number goes on paper before any work starts, and it does not move at the door.

FAQs About Roofers in St. Helena
We schedule St. Helena work on a route basis, so most estimates happen within three to five business days of your call. Inspections can often be scheduled sooner. Call (361) 320-9467 and the person who answers will give you a specific window, not a callback promise.
Yes. The city of St. Helena and Napa County both require permits for full re-roofs, and the permit process includes fire code review. We handle the permit application and coordinate inspections as part of the job. The permit is part of your written price before work starts.
No, but it depends on material choice. Composite shake and certain tile profiles match the original look of redwood or cedar shingles closely, and they carry the Class A fire rating that wood shake cannot. We walk you through the options before you choose. Call (361) 320-9467 for a free estimate.
