Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Larkfield-Wikiup
If you own a surviving pre-2017 home in Larkfield-Wikiup, your roof is now sitting inside a mapped CAL FIRE High Fire Hazard Severity Zone, and that changes what a new roof actually costs and requires. Most residential roof repairs in Larkfield-Wikiup run between $450 and $1,800, while a full Class A fire-rated replacement on a typical 1,800 to 2,400 square foot home lands between $14,000 and $22,000. Birchbark Roofing handles that conversion with a written price before any work starts, shoe covers at the door, drop cloths through the hallway, and a photo of the completed clean-up before the crew leaves. Call (424) 766-4937 to schedule a roof inspection and get your exact number in writing.
Why Birchbark Roofing Is Larkfield-Wikiup’s Preferred Roofing Company
Erik Lindgren and our crew have worked on more Tubbs Fire survivor homes across Larkfield-Wikiup than we can count, and we know what insurers and Sonoma County inspectors look for before they sign off on a roof. Customers in the Mark West area and the streets off Old Redwood Highway tell us the same thing: the insurer sent a cancellation notice, the inspector flagged open-mesh ridge vents, and the window to comply is short. We handle that by documenting every step of the compliance conversion, from ember-resistant soffit screening to the Class A underlayment, so the renewal paperwork matches the roof that is actually on the house.
Every job starts with a written price in dollars, not a verbal estimate. That means you see the allowance structure for hidden decking damage, fascia repair, and any framing fixes before tear-off begins. Our technicians are background-checked and uniformed, and we work with GAF and CertainTeed materials that meet Sonoma County’s HFHSZ standards. A live person answers our phone 24 hours a day, seven days a week, including nights and weekends, so when your insurer sends a 30-day renewal notice, you are not leaving a voicemail.
Birchbark Roofing is part of the Cedarwell family of independent roofing businesses, and every job carries the 365-Day Done Right Promise and the Cedarwell Care Promise. That means if the work isn’t right, we make it right. For families with kids and pets, it also means we ask before we move anything, respect quiet hours, explain the price before the work, and clean up like it is our own home.
Roofing Contractor in Larkfield-Wikiup
A roofing contractor in Larkfield-Wikiup has to understand something most roofers outside Sonoma County never deal with: the same street can have a post-2017 rebuild with a five-year-old Class A roof sitting next to a survivor home from the 1980s with a 30-year-old wood shake roof that insurers are now flagging. When a homeowner needs a roofing contractor here, the job usually starts with a compliance question, not a leak. We begin with a full inspection, verify the parcel’s HFHSZ status, and write the scope to satisfy both the county and the insurance renewal conditions.
Class A Fire-Rated Conversion Scope
A Class A conversion on a surviving Larkfield-Wikiup home goes beyond swapping shingles. We pull the old shake, inspect the decking for split or pulled boards, replace damaged sections, and lay a fire-rated underlayment with ice and water shield in the valleys. Open-mesh ridge vents and unscreened box vents get replaced or screened because ember intrusion through those vents was a primary ignition pathway during the Tubbs event. This portion of the work typically runs $9,000 to $15,000 on top of the base re-roof cost, depending on decking condition and vent count.
Structural Repair and Decking Replacement
On older Larkfield-Wikiup homes, decking damage is common. Decades of Diablo-wind cycling stress eaves and rake edges, and we regularly find boards pulled free or split at the fasteners once the old roofing comes off. Our written price includes an allowance for decking replacement, usually structured at $3.50 to $4.50 per square foot for areas that need new plywood or OSB, so the number is in the contract before anyone climbs on the roof. If the damage exceeds the allowance, we price the additional scope in writing and get your approval before we touch it.
Roof Inspection in Larkfield-Wikiup
A roof inspection in Larkfield-Wikiup is different from a roof inspection in Santa Rosa or Windsor because the inspector has to look at the roof through two lenses at once: the physical condition of the materials and the parcel’s fire-zone compliance status. Most standard roof inspections run between $250 and $450 in Larkfield-Wikiup. If you are preparing for an insurance renewal, we document the assembly in the format insurers expect, including photos of the vents, soffits, underlayment, and any Class A components, so the paperwork matches what the adjuster will see during a re-inspection.
Post-Purchase and Pre-Listing Roof Condition Reports
If you are buying or selling a Larkfield-Wikiup home, the roof inspection should answer one question early: does this roof meet the current HFHSZ requirements at this specific parcel, or will the buyer be looking at a five-figure conversion after closing? We provide a written report with line-item findings and dollar ranges for any remediation, which keeps that conversation on the table before it becomes a surprise at the escrow desk.
Annual Maintenance Walk-Through
We aim to catch issues while they are still in the $500 range: a piece of flashing pulling loose where a valley meets a wall, moss taking hold on the north slope, a vent screen with ember-sized openings. Wet Sonoma County winters averaging 35 to 40 inches of rain stress flashing and encourage moss growth, and spring is the right time in Larkfield-Wikiup to walk the roof before the dry Diablo-wind season arrives.
Trusted Brands We Service in Larkfield-Wikiup
Our Roofing Company team works with materials from GAF, CertainTeed, and Owens Corning, and we keep the components most often needed for post-Tubbs compliance work available for fast turnaround in Larkfield-Wikiup. That includes Class A-rated underlayment, ember-resistant ridge vent systems, and sealed attic vent assemblies that meet CAL FIRE’s ventilation requirements for High Fire Hazard Severity Zone parcels. Whether we are matching a post-2017 rebuild’s architectural shingle profile or converting a survivor home from shake to a CertainTeed Presidential system, we source materials that satisfy both the county’s code and the insurer’s renewal conditions.
Common Roofing Company Problems We See in Larkfield-Wikiup Homes
- Insurer-flagged wood shake roofs on surviving pre-2017 homes. Insurers no longer accept open-mesh ridge vents and wood shake assemblies in mapped High Fire Hazard Severity Zones, and cancellation notices usually carry a short compliance window.
- Decking damage at eaves and rake edges from decades of Diablo-wind cycling. We routinely find split or pulled boards once the old roof comes off, which is why our written price includes a decking replacement allowance rather than waiting for a surprise mid-job.
- Flashing fatigue and moss growth from wet Sonoma County winters. The same roofs that face 35 to 40 inches of annual rain also face hot dry northeast winds in the autumn, and the two-season cycle fails flashings faster than homeowners expect.
- Mismatched repair work from previous storm or leak patches. On some Larkfield-Wikiup streets, older patched asphalt over original wood shake indicates a prior repair done without checking the parcel’s fire-zone status, which can leave the whole assembly out of compliance.

FAQs About Roofing Company in Larkfield-Wikiup
Your insurer is responding to post-Tubbs underwriting rules, not the visual condition of the shake. Larkfield-Wikiup sits inside a mapped CAL FIRE High Fire Hazard Severity Zone, and wood shake roofs cannot legally be re-installed in that designation, so insurers are requiring Class A fire-rated assemblies as a condition of renewal. Call (424) 766-4937 and we will document exactly what your insurer is asking for and put a written price on the compliance conversion.
Once the old shake or composition comes off, the decking, fascia, and flashing are exposed, and on pre-2017 survivor homes we commonly find split decking at the eaves, failed valley flashing, and unscreened vents that let embers into the attic. That is why our written contract includes a decking allowance and an allowance structure for fascia and flashing work, so any hidden condition is priced and approved in writing rather than becoming a surprise.
We start with the parcel’s HFHSZ status and the insurer’s specific renewal conditions, then we tear off and inspect the decking before any new material goes down. The sequence is decking and structural repair first, then the Class A fire-rated underlayment with ice and water shield in valleys, then the sealed ridge vent and ember-resistant soffit and gable vent screening, and finally the Class A roofing system itself. Each step is documented so the insurer’s file matches the roof.
Yes. We provide a written scope of work, material certifications, installation photos of the underlayment and vent configurations, and a final inspection report that corresponds to the insurer’s renewal checklist. In our experience, this documentation shortens re-inspection timelines and eliminates most disputes about whether the roof was actually brought to Class A standards. Call (424) 766-4937 if you have questions about your specific renewal.
Compare the written allowance structure, not just the bottom-line number. One bid may be lower because it assumes the decking is fine and reuses the original vents, while another includes decking replacement allowances and ember-resistant ventilation in the base scope. Ask each bidder whether their price assumes a Class A assembly that will pass a Sonoma County inspection and your insurer’s renewal review, and whether hidden damage triggers a written change order or a vague conversation mid-job.
