Why Birchbark Roofing Fresno Is Los Banos’s Preferred Roof Repair Company
We’ve repaired enough roofs in Los Banos to know what this climate does to them. The summer sun sits above 95°F for weeks at a stretch, cooking asphalt shingles until they curl and crack, and the winter rains find every seam that heat opened up. When we walk a roof here, we’re looking for the failures this specific weather creates, not running through a generic checklist.
Our crews arrive with shoe covers at the door, drop cloths through the hallway, and a written price before any tool comes off the truck. That matters when you’ve got kids doing homework at the kitchen table and a dog who doesn’t understand why strangers are on the roof. Every Los Banos job gets the same treatment: a clean-up photo before we leave, and the 365-Day Done Right Promise in writing. If it’s not right, we make it right. Erik Lindgren built this company around that rule, and it’s stamped on every repair we do.
We’re part of the Cedarwell family of roofing businesses, which has been holding independent roofers to the Cedarwell Care Promise since 2000. That means your Los Banos roof gets the full protection of a national standard, with a local crew that knows this city.

Shingle Roof Repair in Los Banos
Shingle roof repair in Los Banos is the most common call we get, and for good reason: the Central Valley sun bakes asphalt shingles until the adhesive strips fail and the edges curl, then the winter wind rips them off. We replace individual shingles, full slopes, or patch areas of granule loss depending on what we find. In Los Banos, a typical shingle replacement on a newer tract home runs $450 to $950. On an older home near downtown, that number climbs fast because the shingles are often sitting on original 1×6 sheathing that has dry-rotted from decades of heat. We inspect before we quote, so the number you see on the written estimate is the number you pay.
Replacing 1×6 decking under older shingles
On a 1952 bungalow off 6th Street near Henry Miller Park, our crew lifted a corner of the old shingles and found the original 1×6 decking had turned to powder. The drip edge was rusted through, and the felt underlayment crumbled when touched. We wrote the decking replacement into a change order before touching anything, then installed new plywood decking, CertainTeed Landmark architectural shingles with starter strip, and a continuous ridge vent. We pulled a permit so the finished roof met current wind and fire codes. That’s how we work: the surprise gets priced and approved in writing before we move forward, never after.
Nail pops and heat-damaged underlayment
When old underlayment gets brittle from Los Banos heat, new shingles nailed over it tear the paper and leave gaps. Nail pops follow within a season, and so do leaks. We strip back to sound decking whenever it’s needed and explain what we found before we proceed. No guessing, no “we’ll figure it out up there.” You get a line item and a photo.
Storm Damage Roof Repair in Los Banos
Storm damage roof repair in Los Banos usually means wind-lifted shingles after a winter front, or water that got past old flashing during a heavy rain. We respond quickly when a storm passes through, and we document everything with photos for your insurance claim. A common storm repair here runs $600 to $1,400, depending on how many slopes took damage and whether the underlayment stayed intact. If your insurance adjuster needs to see it, we’ll be there with notes and photographs.
Wind damage and missing shingles
Los Banos sits in a flat valley where storm winds roll through without much to slow them down. Older roofs lose shingles first at the eaves and ridges, where uplift is strongest. We replace what’s gone, re-seat what’s lifting, and check the drip edge for rust that could let water wick into the fascia during the next storm.
Leaks after winter rain
When the first real rain of the season hits a Los Banos roof that baked all summer, leaks show up at the valleys and around vent boots. We trace the water back to its entry point, not just its exit, and repair the actual source. Patching a ceiling stain without fixing the roof above it is a waste of your money, and we won’t do it.
Trusted Brands We Service in Los Banos
We work with shingle and tile from CertainTeed, GAF, and Tamko, all of which hold up well under the Los Banos sun when installed correctly over sound decking. For older homes where you want to match a 1950s architectural look without the maintenance of a real shake roof, CertainTeed Landmark and GAF Timberline give the shadow-line appearance with a modern warranty. We stock common trim and flashing locally so a typical repair doesn’t wait on a parts truck from the Bay Area.

AfterCommon Roof Repair Problems We See in Los Banos Homes
- Dry-rotted 1×6 sheathing on pre-1970 homes. The original decking around Henry Miller Park and the older streets downtown has spent 60-plus summers cooking under asphalt. When it crumbles, a simple shingle repair becomes a decking replacement, and that changes the scope and the permit path.
- Rusted or missing drip edge on 1950s bungalows. Skipping drip edge replacement on an older Los Banos home lets rainwater wick straight into the fascia boards. Two winters later, you’re paying for fascia repair on top of the roof work.
- Brittle underlayment that tears under new shingles. Homes with minimal attic insulation bake the roof from both sides, and the felt underlayment turns to parchment. Nailing new shingles over it creates leaks that weren’t there before.
- Valley and vent boot failures after summer heat cycles. Expansion and contraction from Los Banos temperature swings loosen flashing at valleys and around plumbing vent boots. These are small, cheap fixes when caught early and expensive water damage when ignored.

FAQs About Roof Repair in Los Banos
Because when you open up a 1950s-era roof and touch the sheathing, decking, or structural framing, the City of Los Banos wants to inspect the work against current codes. Newer subdivisions typically have plywood decking that’s still sound, so a shingle overlay doesn’t trigger structural review. The permit protects you: it means a city inspector signs off that the decking, underlayment, and fastening meet today’s wind and fire standards, not 1952’s. We pull the permit, schedule the inspection, and pass it before we consider the job done. If you’re wondering whether your specific repair needs one, call (559) 785-9461 and we’ll tell you straight.
1×6 sheathing means the roof deck is made of boards, usually pine, that are roughly one inch thick and six inches wide, laid with gaps between them instead of solid plywood sheets. It was the standard way to build a roof deck in the 1940s through the early 1960s, so it shows up constantly in the older Los Banos neighborhoods like the streets around Henry Miller Park. It matters because those boards dry out, split, and rot under the Central Valley heat, and modern shingles need a flat, solid surface to fasten to. If your repair opens up old 1×6 decking, we’ll show you what we found and price the replacement before we go further.
Yes. We typically use architectural shingles from CertainTeed or GAF with a dimensional, shadow-line profile that mimics the look of old shake or shingle without the maintenance or fire risk. The original shake roofs on Los Banos homes near Henry Miller Park haven’t survived well, but the look is part of the house’s character. A high-definition architectural shingle in a weathered wood tone gets you close, and it meets current fire codes, which old cedar never did. We’ll show you physical samples before you commit.
If a named storm passed through and you’re seeing missing shingles, lifted edges, or interior water stains, document what you can and call us within a week. Insurance adjusters want evidence that the damage came from a specific storm event, not general wear. We photograph everything at the start, mark the damage areas, and provide a written repair scope you can hand to your adjuster. We’ll be on site when the adjuster arrives if you want us there. The estimate is free, and if the claim is denied, that’s your call on whether to proceed anyway. Call (559) 785-9461 and we’ll start the documentation.
Because homes from that era were built before radiant barrier became standard in California, and your attic is turning that summer heat into a convection oven under your roof deck. A radiant barrier, stapled to the underside of the rafters, reflects a large share of that radiant heat before it cooks your shingles from below and drives your cooling bill up. It’s a small addition while the roof is open that pays back every summer after. We’ll include it as an optional line item on your written estimate, not a surprise add-on.
