Twin Peaks homes often date from the mid-20th century with wood-frame construction on steep slopes above Lake Arrowhead and Crestline. After fire, load-bearing walls and roof trusses suffer hidden charring that only reveals itself once finishes are stripped. Crews must evaluate for San Bernardino County seismic and snow-load requirements before any framing begins, because replacing members without upgrading connections can leave the structure vulnerable during the next heavy winter.
Winter conditions complicate every phase. Snow accumulation adds dead load to already compromised roofs, and freeze-thaw cycles can widen cracks in remaining timbers. Access roads narrow quickly after storms, so material staging happens from the 26100 CA-189 yard with smaller loads hauled up CA-189. Summer work brings its own issues: rapid drying of exposed sheathing can cause additional checking if temporary moisture barriers are not installed promptly.
Repairs frequently involve sistering joists with pressure-treated lumber rated for exterior exposure, installing new hurricane ties, and sheathing with fire-retardant plywood where code triggers apply. Hidden damage behind stucco or log siding is common in Twin Peaks cabins; infrared scans and selective demolition are standard before any bid is finalized. Homeowners who attempt cosmetic fixes without addressing these concealed members usually face repeat failures once snow returns.
Technician insight
In Twin Peaks, the thing that catches most people out with Structural repair after fire is the extra dead load from winter snow sitting on a roof whose trusses were already heat-weakened. Homeowners clear the visible debris but miss how quickly a few inches of wet snow on compromised rafters turns into a collapse before we can get temporary bracing up from the CA-189 yard.
Compromised Ridge Beam on Steep Lot
Fire reached the ridge in a 1960s cabin above Twin Peaks. We found deep char on the ridge beam and rafters already sagging under early snow. Temporary posts were set from the road, damaged members were sistered with engineered lumber, and new hurricane ties were added to meet current county snow-load specs. The roof held through the rest of the winter without further movement.
How it works
- 1
Initial Assessment
Technicians inspect framing, foundations, and roof systems for char depth and structural compromise while documenting San Bernardino County code triggers.
- 2
Stabilization
Temporary shoring and weather protection are installed to prevent snow-load collapse and further water intrusion from mountain storms.
- 3
Selective Demolition and Repair
Damaged members are removed, new framing is sistered or replaced, and connections are upgraded to current snow-load and seismic standards.
- 4
Final Inspection and Weatherproofing
Completed work is verified against county requirements, then the structure is sealed against Twin Peaks freeze-thaw cycles before finishes return.
Pricing
Costs depend on extent of hidden damage, roof pitch, and whether snow-load upgrades are required.
