Fast, Reliable Roof Replacement Across Big Bear Lake
Roof replacement in Big Bear Lake typically runs $14,000-$28,000 for a standard asphalt shingle tear-off on a mid-size cabin, with architectural shingles and upgraded snow-and-fire assemblies pushing toward the higher end. Most full replacements take 3-7 working days once materials are staged, weather permitting. We schedule Big Bear Lake work around mountain snow windows, not against them, and every job starts with a written price before any material is ordered.

What makes Big Bear Lake different from every down-the-hill roof we replace is the dual code burden: California high-elevation snow-load requirements on top of Wildland-Urban Interface Class A fire mandates. Your roof has to hold heavy snow all winter and resist ember intrusion during fire season. That is a different job than a Riverside or Redlands reroof, and it is the reason we treat every Big Bear Lake replacement as its own mountain project rather than a standard tear-off.
Why Birchbark Roofing Is Big Bear Lake’s Preferred Roof Replacement Company
We are the crew that shows up with shoe covers at the door, drop cloths through the hallway, and a clean-up photo before we pull out of the driveway. Families in Big Bear Lake with kids and pets tell us that is what they remember, more than the shingle color. A live person answers our phones 24 hours a day, including weekends, so when a guest calls from your rental on a Saturday morning with a ceiling stain, someone is on it before checkout.
Our technicians are background-checked and uniformed, so you know exactly who is walking onto your property before a ladder goes up. We are part of the Cedarwell family of independent roofing businesses, operating since 2000, and every replacement carries the 365-Day Done Right Promise: if the work is not right, we make it right. That promise is stamped on every Big Bear Lake job. Erik Lindgren, our owner, holds every project in this mountain market to the same written standard: inspection first, allowance written into the contract, and no change order priced after the fact.
And because we know this mountain, we schedule around the freeze-thaw cycle. We will not strip a roof the day before a storm front rolls in off the Pacific and turns your decking into a skating rink. Big Bear Lake weather dictates when we work, and we plan tear-offs in sequence so your home is dried in before snow or rain arrives.
Reroofing in Big Bear Lake
Reroofing in Big Bear Lake means stripping the existing shingles, inspecting the decking, upgrading to code-mandated ice and water shield at the eaves and valleys, and replacing with a Class A fire-rated system that also holds up under 60-100+ inches of annual snowfall. A typical reroof on a 1940s-1970s cabin runs $14,000-$22,000 depending on square count, decking condition, and whether we are also addressing rotted rafter tails discovered after tear-off. The written price we give before any work starts includes the tear-off, hauling, underlayment, flashing, and shingle installation.
What tear-off reveals on older cabins
On homes near Big Bear Boulevard and in the Boulder Bay area, tear-off regularly uncovers what the shingles were hiding: compressed rafter tails, rusty flashing at plumbing penetrations, and decking that has been wet for years from ice damming. We sister soft framing, replace bad decking, and install full ice and water shield. That is not a surprise upgrade, it is an allowance written into the contract so the cost is pre-approved before we order material.
Shingle systems sized for snow
A reroof here is not the same shingle stack we install in the Inland Empire. We specify architectural shingles from GAF, CertainTeed, or Owens Corning laid over a full-width ice and water barrier at eaves, valleys, and around penetrations. The combination is what lets your roof survive the melt-and-refreeze cycle that kills lesser assemblies from the inside out.
Flat Roof Replacement in Big Bear Lake
Flat roof replacement in Big Bear Lake is most common on the additions, porches, carports, and low-slope sections tied to the original mid-century cabins. A flat or low-slope section on a mountain home needs a system built for ponding snowmelt and freeze-thaw cycling, not a membrane spec from a coastal job file. Expect $9,000-$16,000 for a typical single-story flat roof replacement on a Big Bear Lake cabin, including tear-off to the deck, new tapered insulation where needed, and a Class A fire-rated membrane system. We use Boral and Tamko single-ply and modified bitumen products where the slope allows.
Ice dam failure on low-slope sections
Flat and low-slope roofs here collect snow in ways a pitched roof never does. When meltwater cannot drain because the edge is frozen solid, water backs up and finds its way through seams, flashing laps, and even nail penetrations. We see this every spring on cabins where the porch roof joins the main A-frame. The fix is not patching the surface, it is a properly flashed drain path and a membrane that handles repeated freeze stress.
Class A rating on flat sections
Any flat roof replacement in Big Bear Lake must carry a Class A fire-resistance rating to meet WUI codes. That is non-negotiable here. The cedar shake and lightweight composition roofs that were common in the 1960s fail that test, which is exactly why we replace them with rated systems and document the rating for your permit record.
Trusted Brands We Service in Big Bear Lake
Birchbark Roofing works with materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and our Big Bear Lake crews stock local parts for the most common mountain roof assemblies. If your A-frame is wearing a GAF architectural shingle that is no longer in standard production, we match the profile rather than telling you the whole roof needs to come off early. We also service and replace Atlas and Boral systems on the flat and low-slope sections we see throughout Big Bear Lake.
Common Roof Replacement Problems We See in Big Bear Lake Homes
- Ice damming at the eaves. Meltwater refreezes at the cold roof edge, forcing water backward under the shingles and into rafter bays. By the time a homeowner notices a brown stain on a bedroom ceiling, the soffit, fascia, and insulation behind it are often saturated and rotted.
- Undersized framing from the 1940s-1970s cabin era. Many of these original vacation cabins were never engineered for California’s high-elevation snow-load requirements. Rafters deflect, valleys compress, and the roof sags under annual accumulation until the decking itself needs to be sistered or replaced when we get it open.
- High-altitude UV granule loss on asphalt shingles. Intense UV at nearly 7,000 feet strips granules faster than down the hill, and because many homes are absentee-owned, the roof can be bare by late summer and nobody notices until the next meltwater event exposes it.
- Wood-shake and lightweight composition roofs out of compliance with fire codes. Original shake roofs that once looked right on a mountain cabin now fail WUI Class A requirements. We carry the replacement systems and documentation to bring the property into compliance, and we handle the permit paperwork as part of the job.
Pricing for Roof Replacement in Big Bear Lake, CA
Here is honest Big Bear Lake money. A reroof on a standard mid-size cabin runs $14,000-$22,000. A full replacement on a larger A-frame with architectural shingles, full ice and water shield, and decking repairs lands between $18,000 and $28,000. Flat roof sections run $9,000-$16,000. The two biggest cost drivers are decking condition after tear-off and the snow-and-fire upgrades the permit triggers, both of which we write into your contract as allowances.

FAQs About Roof Replacement in Big Bear Lake
Yes, it often does. Once we open a roof in Big Bear Lake, the building inspector looks at the framing the way it actually is, not the way it was drawn in 1955. If the rafter tails are rotted or the existing decking does not meet current snow-load standards, the permit will require repair or replacement before the roof can be closed. That is why we write framing and decking allowances into your contract before tear-off, and why no code upgrade is ordered without your written approval. Call (424) 766-4937 and we will walk you through exactly how we handle permit-triggered repairs so none of it is a surprise.
A square is 100 square feet of roof surface, and it is the unit every legitimate Big Bear Lake bid uses. Comparing bids by total job price only works if the measured square count is the same, because material, tear-off labor, and underlayment are all priced per square. If one bidder measures 28 squares and another measures 24, someone is wrong, and the one who is wrong will either ask for more money mid-job or under-build your ice and water shield. We show you the square count on the written estimate, so you can compare line by line. Call (424) 766-4937 for a precise square measurement of your roof.
Your roof needs a Class A fire-resistance rating under WUI code and a structural assembly that meets San Bernardino County’s high-elevation snow-load requirements. That means Class A rated shingles or membrane, full ice and water shield at eaves and valleys, and decking and framing that will not deflect under 60-100+ inches of annual snowfall. A standard down-the-hill assembly does not meet that bar. We spec every Big Bear Lake replacement to satisfy both code requirements and document it for your permit record. Call (424) 766-4937 if you are not sure what your current roof is rated for.
We do both. Many Big Bear Lake cabins have a pitched main roof and a flat or low-slope section over the porch, carport, or addition, and we replace those flat sections as part of the same job. Boral and Tamko membranes are our go-to for low-slope mountain work because they hold up to ponding snowmelt and repeated freeze cycles. We will give you one written price for the whole roof, pitched and flat sections included. Call (424) 766-4937 to schedule a look at your flat roof section.
You get the clean-up photo before the crew leaves, every day of the job. Since many Big Bear Lake roofs are on vacation rentals managed from Los Angeles or Orange County, we build communication into the work: photos of the tear-off, photos of any framing found after the deck is exposed, written change-order pricing before any additional work is ordered, and a final clean-up photo showing the property back to guest-ready condition. You will never hear about a problem after it has already been fixed without your sign-off. Call (424) 766-4937 and we will set the communication schedule that works for you and your property manager.
