Why Mercer Roofing Is Big Bear City’s Preferred Roofing Company Company
Grant Whitlock leads our Big Bear City work personally, and he knows what a mountain roof has to survive. Homeowners here don’t call because a shingle blew off in a mild Santa Ana. They call because three feet of wet snow is sitting on a 1960s A-frame and the ceiling is staining. Our Roofing Company team shows up in marked trucks, badged and uniformed, and we send the technician’s name and photo to your phone before arrival. No stranger at the door guessing. That’s the Threshold Standard every Mercer location is held to, and it’s written into how we operate.
Big Bear City homeowners tell us the same thing: they’ve had valley roofers drive up, look at the roof, give a verbal number, and disappear when the permit office asked for a snow-load calculation. That’s why they call Mercer Roofing for Big Bear City Roof Repair that starts with the structural check first. We do the structural check first, put every number in writing, and show up when we say we will. Our 365-Day Done Right Promise covers every repair for a full year, in writing, on every job. If a repair fails, the second visit is free.
Free Roof Estimate in Big Bear City
A Free Roof Estimate in Big Bear City means one of our roofers gets on the roof, checks the decking, flashing, underlayment, and eaves, and gives you a written line-item price before any work starts. For older cabins built in the 1950s through 1970s, that inspection often finds what the last roofer skipped: rotted eaves from decades of ice dams, missing ice and water shield, or undersized rafters that won’t pass a county snow-load review. Most Big Bear City estimates take 45 to 90 minutes, and the price we write is the price you pay.
What We Check During a Big Bear City Estimate
We look at the condition of what’s under the shingles, not just the shingles themselves. On an A-frame near the Big Bear City airport, our crew tore off failing wood shake and found rafters undersized for the 100 psf snow-load requirement that San Bernardino County enforces. The homeowner had no idea the roof couldn’t support a code-compliant re-roof without framing work. We documented it, priced it, and got written approval before we touched a single rafter. That’s what an estimate is for.
written Estimate, Not a Verbal Guess
Every estimate includes the exact scope, materials, permit work, and any structural allowances we see coming. No change orders show up later. No “we didn’t know it was that bad.” If the county requires something after we open the roof, we handle it with a written allowance we agreed on before demo started.
Roofing Contractor in Big Bear City
When you hire a Roofing Contractor in Big Bear City, you’re hiring someone who understands that San Bernardino County reviews the existing roof structure’s snow-load rating before re-roofing older cabin-era homes. Undersized rafters or missing ice and water shield at the eaves get flagged. A contractor who only works downhill in the Inland Empire won’t expect that, and it’ll cost you time and money when the inspector stops the job. Mercer Roofing plans for it from day one.
We pull permits, coordinate the structural review, and schedule the inspection so the job doesn’t stall. We replace rotted decking, install ice and water shield at the eaves, and use nailing patterns rated for mountain wind loads. The inspector sees a roof built to Big Bear conditions, not Valley shortcuts.
Permits and Structural Work Included
San Bernardino County ground snow loads in the Big Bear Valley can exceed 100 psf. On older homes, that often means sistering rafters or adding collar ties before new decking goes on. We write that into the contract as a visible allowance, with the actual work priced and approved in writing before we touch any framing.
On that 1968 A-frame near the airport, we tore off the failed wood shake and found rafters undersized for the 100 psf requirement. We added ice and water shield at the eaves, installed a ridge vent, replaced the fascia and drip edge, and laid GAF architectural shingles with a 130 mph wind rating. We photographed every rafter repair for the inspector. The permit closed with zero correction notices.
Trusted Brands We Service in Big Bear City
Mercer Roofing installs and repairs GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral shingle systems. In Big Bear City, we stock the materials that actually hold up at altitude. Atlas StormMaster and GAF Timberline architectural shingles are common choices here because their wind ratings and UV resistance match what mountain weather demands. We keep flashing, ice and water shield, and underlayment on hand so a repair doesn’t wait on a supply run down the mountain.
Common Roofing Company Problems We See in Big Bear City Homes
- Ice dams at the eaves on 1960s and 1970s cabins. Daily freeze-thaw cycles in fall and spring push meltwater up under the shingles, and homes built as seasonal retreats often have no ice and water shield installed. Rotted eaves and decking follow within a few years.
- Undersized rafters on older A-frames and wood-frame cabins. Many of these homes were built before modern snow-load standards were enforced. The county now requires a structural check before re-roofing, and older rafters frequently fail the review.
- High-altitude UV degradation. Shingles at 6,752 feet take far more ultraviolet radiation than roofs at valley elevations. Granule loss, curling, and cracking arrive years earlier than a typical manufacturer’s warranty assumes, so we select materials accordingly.
- Re-roofing over failed underlayment. The old wood shake and early composition roofs on Big Bear City’s 1950s-70s housing stock were never engineered for sustained snow loads. Laying new shingles over a failed underlayment just traps moisture behind the new roof and guarantees another failure within a few freeze-thaw seasons.

FAQs About Roofing Company in Big Bear City
San Bernardino County requires a permit review of the existing roof structure’s snow-load rating before re-roofing older cabin-era homes in Big Bear City. Ground snow loads here can exceed 100 psf, and many 1950s-70s cabins were built before that standard existed. Valley roofers don’t encounter this because their jurisdictions don’t see annual snow loads. If the rafters fail the review, the inspector won’t approve the re-roof until framing is corrected. We include this check in our estimate so it doesn’t blindside you mid-project. Call (743) 200-8347 and we’ll explain what your specific home needs.
Without ice and water shield at the eaves, meltwater from snow and ice dams seeps under the shingles and rots the decking and fascia. On Big Bear City homes built as seasonal cabins in the 1960s, this is common because the original roofs weren’t engineered for year-round freeze-thaw cycles. We replace the rotted wood, install ice and water shield, and then lay the new roof so meltwater can’t back up under it. This is one of the most frequent repair jobs we do up here.
For a typical A-frame in Big Bear City, expect $16,000 to $28,000 for a full re-roof including structural corrections, depending on roof size and how many rafters need sistering or upgrading. The structural work alone usually adds $3,000 to $11,000. We write the structural allowance into the contract up front, and every dollar is approved in writing before we start that work. No surprise invoices. Call (743) 200-8347 for a written quote on your cabin.
Altitude and UV. At 6,752 feet, Big Bear City roofs take significantly more ultraviolet radiation than roofs at valley elevation, and the daily freeze-thaw cycles in fall and spring stress the shingle granules and adhesive strips. A 25-year shingle may last 15 to 18 years up here. That’s why our Roofing Company team recommends brands like Atlas and GAF architectural shingles rated for high wind and extended UV exposure.
A “square” is 100 square feet of roof area. So 28 squares means 2,800 square feet of roofing surface. In Big Bear City, that’s a common size for a mid-century cabin or A-frame with steep pitches. When we quote by the square, we include all materials, labor, underlayment, flashing, ice and water shield at the eaves, and permit work. If a quote seems low, ask what’s excluded. Usually it’s the structural check or the ice and water shield, and those are exactly what Big Bear homes can’t skip. Call (743) 200-8347 and we’ll walk you through a square-by-square comparison.
