We know Kentfield’s streets, its rainfall patterns, and what the redwoods and oaks drop onto your roof all winter.

Why Birchbark Roofing Is Kentfield’s Preferred Roofing Company
Our Roofing Company crews work Kentfield every week, which means we don’t have to study a map before showing up. We know that the stretch along College Avenue holds 1920s Craftsman bungalows with original skip sheathing, that Kent Woodlands lots climb steeply enough to change how we stage tear-off, and that the canopy along Sir Francis Drake Boulevard keeps roofs wet long after the rain stops. That local pattern recognition means our bids account for what’s actually under the old shingles, not just what’s visible from the driveway.
Erik Lindgren, who leads Birchbark Roofing, started contracting on Bay Area hillside homes where the difference between a good roofer and a great one shows up in the valleys, the eaves, and the flashing. We carry that same standard into every Kentfield job. Homeowners here tell us the same thing: the crew showed up in uniform, laid drop cloths through the hallway, kept the gate closed so the dog didn’t wander, and sent a photo of the cleaned-up yard before the truck pulled away. That’s not a bonus. That’s the baseline.
Every Kentfield project gets a written price before tear-off starts, and every repair and replacement carries the 365-Day Done Right Promise. If our work isn’t right, we make it right. No fine print, no phone tag.
Commercial Roofing in Kentfield
Commercial Roofing in Kentfield means low-slope and flat systems on small professional buildings, boutique offices, and the occasional mixed-use property near the College of Marin corridor. Flat roofs here carry a heavier moss and debris load than the pitched residential roofs around them, and the winter damp that settles over Kentfield accelerates membrane wear at seams and penetrations. Most commercial flat roof repairs in Kentfield run $1,400-$5,500 depending on the membrane type and how many layers we’re cutting through, while a full commercial tear-off and recover typically lands between $14,000 and $38,000.
What a Commercial Roof Check Covers
We start with the drains and scuppers, because a clogged drain on a flat Kentfield roof sends water sideways into the parapet and the interior. Then we map every penetration, HVAC curb, and seam, looking for the alligator cracking and membrane shrinkage that sustained moisture causes here. If it’s a foam or coating roof that’s reached the end of its life, we talk straight about whether patching is still reasonable or if you’re better off recovering now.
Permits and Code Compliance
A commercial re-roof in Kentfield triggers a Marin County permit, and we pull it ourselves, including any Wildland-Urban Interface material checks if your building sits in a mapped hazard zone. We don’t ask you to navigate the county’s requirements. Erik Lindgren’s crew handles the paperwork and confirms the assembly meets current code before the first square of membrane leaves the truck. You get a written price for the full scope, including permit, before we start.
Metal Roof Installation in Kentfield
Metal Roof Installation in Kentfield is one of the smartest moves a homeowner here can make, specifically because this town stays wet for months at a time. Standing seam and metal shingle systems shed moss and organic debris far better than composition, and they carry Class A fire ratings that satisfy Marin County’s Wildland-Urban Interface requirements on the hillside lots where wood shake is no longer legal. A full standing seam replacement on a typical Kentfield home runs $28,000-$55,000, while a metal roof over a smaller ranch or carriage house usually lands between $19,000 and $32,000.
Why Metal Works in a Rain Shadow
Kentfield’s position against Mount Tamalpais pushes rainfall to 50 to 60-plus inches a year, roughly double what San Rafael sees a few miles east. That persistent moisture is hard on asphalt, but metal’s interlocking panels and concealed fasteners give water fewer places to sit and fewer ways in. We also flash every valley, chimney, and skylight with the assumption that water will pool and flow heavily for months, because it will.
What Actually Goes On the Roof
We don’t lay metal over rotted decking. On a Kentfield metal job, we inspect what’s underneath, replace any saturated or sistered sheathing, and put a high-temp ice and water shield across the valleys and eaves before the panels go down. You see the decking report and the line-item decking allowance in your written price before anyone climbs the ladder. If the old roof was shake, the WUI designation means the new assembly must be Class A, and metal checks that box outright.
Trusted Brands We Service in Kentfield
We work with materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we carry a strong selection of GAF, Atlas, and Tamko product lines for Kentfield jobs because they hold up well under this town’s moss pressure and damp winters. If a Kentfield homeowner has a warranty claim or needs a matching shingle after a repair, we can usually get the right product from our local stock without a multi-week wait. You’ll know exactly which brand and line we’re quoting, and why, before you sign anything.
Common Roofing Company Problems We See in Kentfield Homes
- Moss and lichen loading under the redwood canopy. Kentfield’s dense redwoods, bay laurels, and oaks drop organic debris constantly, and 50 to 60 inches of annual rain keeps it damp. We treat moss as a standing condition here, not a cosmetic issue, because it traps water against the shingle and rots the decking underneath.
- Saturated skip sheathing on pre-1970 homes. Many Kentfield Craftsman bungalows and early ranches still carry original 1x skip sheathing under old shake or early composition. Once the old roof is off, we routinely find sections too waterlogged to hold a fastener, and that decking must be replaced before anything new goes on.
- Rotted eave and valley framing you can’t see from the ground. The combination of heavy rain and tree shade means water sits at the eaves and valleys for months. We’ve opened up Kent Woodlands roofs and found rafter tails sistered with rot that no driveway inspection would ever reveal.
- Wood shake on Wildland-Urban Interface lots. Much of Kentfield’s hillside is mapped as WUI, which legally bars a like-for-like shake replacement. Homeowners sometimes assume they can put the same material back, but Marin County requires a Class A fire-rated assembly, and we handle that permit and material compliance from day one.

FAQs About Roofing Company in Kentfield
No, in most of Kentfield you cannot. Large portions of the hillside are mapped as Marin County Wildland-Urban Interface, which legally requires a Class A fire-rated assembly on re-roofs, and wood shake does not meet that rating without expensive, often impractical treatment. If your home sits in a WUI zone, we’ll pull the county permit and confirm the required assembly before quoting, so you’re not surprised later. Call (424) 766-4937 and we’ll check your specific lot.
Because Kentfield sits in an orographic rainfall shadow against Mount Tamalpais and receives roughly double San Rafael’s annual rainfall, with 50 to 60-plus inches a year, plus a dense redwood and bay laurel canopy that keeps roofs shaded and damp for months. That combination of constant moisture and organic debris loading means moss here is a near-annual condition, not a one-time fix. We treat it as a maintenance issue and can set you up on a clearing schedule that matches your roof’s actual load. Call (424) 766-4937 to talk through what your roof needs.
Usually one of three things: saturated skip sheathing from decades of trapped moisture, rotted eave or valley framing that only shows up once the old roof is off, or a WUI material upgrade the county requires. On a 1940s Craftsman in Kent Woodlands, our tech pulled failed shake off a valley and found all three plus rusted-through flashing. We price a decking and framing allowance into the written quote, and if we find more damage, you get a change order in writing, priced and signed, before we touch it. Call (424) 766-4937 and we’ll show you exactly how we contract for what’s under the old roof.
The valleys, the eaves, and every penetration through the roof are the most vulnerable on Kentfield homes, because they collect debris from the canopy and hold moisture longer than the open field of shingles. We routinely find flashing corrosion and rot concentrated where a valley meets a dormer or where the eave overhangs a shaded north side. Those are the spots we inspect first, and the spots we reinforce with ice and water shield when we re-roof. Call (424) 766-4937 to have us look at yours.
Yes, we install standing seam and metal shingle roofing in Kentfield, and yes, it helps significantly with the wet because metal sheds moss and organic debris far better than composition, with no granule loss from the constant damp. Metal also carries the Class A fire rating Kentfield’s WUI hillside lots require. If you’re weighing a metal roof, call (424) 766-4937 and we’ll quote it with the decking and underlayment work included, in writing.
Living with a Kentfield roof means living with rain, canopy, and fire-code rules that most towns don’t juggle at once. We contract for what’s under the old roof before we bid it, we write the price down, and we leave the yard cleaner than we found it. Call (424) 766-4937 to schedule your free estimate.
