Fast, Reliable Roof Replacement Across Crestline
Roof replacement in Crestline runs $11,000 – $28,000 for a typical tear-off and new roof on an older mountain home, with steep-pitch and snow-load upgrades pushing the higher end. That’s the honest range for this market, and it reflects the reality of working at 4,000 – 5,000+ feet, where winter access, fire-rated assemblies, and structural surprises are part of the job. Orange County Roofing Co knows Crestline’s roofs differently than a flatland crew from down the hill. We’ve worked the San Bernardino Mountains long enough to know that a cabin roof isn’t just a cover – it’s a snow-shedding, ember-blocking, freeze-thaw-resistant assembly that either works or fails spectacularly. If you’re planning a Roof Replacement and want straight answers about what your older Crestline roof will need, call us at (866) 942-4187. We’ll walk you through it before you spend a dime.
Why Orange County Roofing Co Is Crestline’s Preferred Roof Replacement Company
Mountain roofing demands a different skill set, and we built our approach around it. Our crews understand that Crestline homes aren’t like tract housing in San Bernardino or Highland. They’re steep, wood-framed cabins and A-frames with limited attic ventilation and original decking that’s been through forty winters of freeze-thaw. That’s not a problem we’re surprised by – it’s the reason we start every Crestline replacement with a tear-down inspection of the existing assembly, not a quick glance from a ladder.
Crestline homeowners call us because we explain what they’re actually buying. Kurt Hensley has built our reputation on the simple fact that we carry seven major shingle brands – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral – so the recommendation you get is based on what your roof actually needs at this elevation, not what’s easiest for us to stock. When a Lake Gregory-area homeowner asks whether they should pay more for a Class A impact-resistant shingle, we can show them the trade-off against what their current roof is doing. That’s the difference between a roofer and a specialist.
We also handle the full lifecycle: inspection, repair, and full replacement under one team. So if you’re not sure whether you need a reroof or a targeted repair, we can tell you without a sales pitch attached. Our roof inspections in Crestline are a standalone service, not a foot-in-the-door. If your roof is fine, we’ll say so.
Styles & brands we work with






Reroofing in Crestline
Reroofing in Crestline usually means a full tear-off, not an overlay, because the older cabins up here were built with original wood decking that fails under today’s snow-load and uplift requirements. When a homeowner asks us if we can just lay new shingles over the old roof, the honest answer is usually no – a straight overlay is rarely a legal shortcut at this elevation, and it hides exactly the problems you’re paying to fix. A typical tear-off reroof in Crestline runs $11,000 – $22,000 depending on pitch, square footage, and how much decking needs replacement once we open it up.
Full Tear-Off and Re-Deck
We remove the existing roofing down to the framing, inspect every inch of decking, and replace any soft or rotted sections before the new assembly goes on. This is where Crestline houses differ from flatland homes – the pine needles behind chimneys and in valleys have often been holding moisture for years, and the wood underneath tells the story. We write the change order before we touch the damaged decking, so you know exactly what the added cost is before we proceed.
Snow-Load and Fire-Rated Assembly
At 4,000 – 5,000+ feet, your replacement roof has to be built for snow accumulation and wildfire exposure, not just rainwater shedding. We install ice and water shield through valleys and eaves, upgrade flashing at penetrations, and spec Class A fire-rated shingles as the baseline for Crestline work. The assembly matters more than the shingle brand, which is why we explain the underlayment and flashing details up front rather than burying them in the fine print.
Flat Roof Replacement in Crestline
Flat roof replacement in Crestline is less common than steep-slope work, but plenty of older mountain homes and additions have low-slope or flat sections – porches, dormers, garages, and the occasional 1970s contemporary. A typical flat roof replacement here runs $8,500 – $16,000 for a full tear-off and new membrane system, depending on the size and whether the underlying decking has water damage. Flat roofs at this elevation face a specific problem: snow sits on them, pine needles pile up, and any ponding water becomes an ice dam in winter.
Tear-Off and Membrane Replacement
We strip the old membrane down to the decking, check the substrate for rot and deflection, and install a new membrane system selected for Crestline’s snow and debris conditions. Because flat surfaces collect pine needles and hold snow longer than pitched roofs, proper drainage and seam detailing matter more here than anywhere else on the house. We’ll tell you if your existing flat section has been failing because of clogged drains rather than membrane age, and fix both in one pass.
Decking and Structural Repair
Older flat roof sections on Crestline cabins often have plywood decking that’s been wet for years. We don’t cover over it – we replace it. The change order comes to you in writing before we cut anything, so there’s no surprise at the end. That’s how we handle every Crestline job: the inspection tells you what’s actually there, and the contract reflects it.
Trusted Brands We Service in Crestline
We install Atlas, Tamko, and GAF products up here, along with the rest of our seven-brand lineup, and we stock the specific accessories Crestline homes need: ice and water shield, ridge vents sized for mountain attics, and ember-resistant flashing details. Because we’re material-agnostic, we’ll tell you which shingle actually performs best on a steep gable at 5,000 feet with pine overstory – not just the one with the biggest marketing budget. We carry the parts for Crestline jobs, which means less waiting and fewer trips up and down the mountain.

AfterCommon Roof Replacement Problems We See in Crestline Homes
- Pine needle rot in valleys and behind chimneys. Dense pine overstory drops needles that collect in roof valleys and behind chimney crickets, holding moisture against the sheathing for years. By the time the roof comes off, the decking underneath is often soft and needs replacement, which is exactly what happened on a chalet-style cabin off the Lake Gregory village side we recently re-roofed.
- Original wood decking that no longer meets code. Many Crestline cabins were built as weekend places in the 1960s – 1980s with 3/8″ plywood or skip sheathing that doesn’t meet current uplift or snow-load requirements. Tearing off the old roof routinely exposes framing that has to be upgraded before the new assembly can pass inspection.
- Failed ice and water shield at eaves and valleys. Freeze-thaw cycles and winter rain get behind thin flashing at penetrations, and once the underlayment fails, water moves into the framing. We re-lay ice and water shield through every valley and eave, not just the minimum code strip.
- Inadequate attic ventilation. Older Crestline cabins often have minimal or no ridge venting, which cooks the underside of the roof deck in summer and traps moisture in winter. We size ridge vents for the actual attic volume, which most flatland crews never bother to calculate.
Pricing for Roof Replacement in Crestline, CA
A full roof replacement in Crestline typically runs $11,000 – $28,000 for a tear-off, decking repair, and new shingle or metal assembly. Flat roof sections run $8,500 – $16,000. What pushes a Crestline quote toward the higher end: steep pitch (anything over 8/12 requires staging and safety equipment), snow-load upgrades to the framing, extensive decking replacement, and Class A fire-rated materials. What brings it down: a simple gable roof with sound decking and normal access. We give written line-item quotes, and any decking or framing surprise gets a written change order before we touch it.

FAQs About Roof Replacement in Crestline
Your quote can change if we find hidden decking rot or framing damage that we couldn’t see before the tear-off, and we handle that by writing a change order for your approval before we do the extra work. This is common on older Crestline cabins where pine needle rot has been hiding behind valleys and chimneys. You’ll get a written line-item quote up front, and any surprise gets priced and approved in writing before we proceed – not after the fact.
A Crestline reroof costs more because mountain roofing requires snow-load-rated assemblies, Class A fire-rated materials, ice and water shield through valleys and eaves, and often significant decking replacement once the old roof comes off – none of which a flatland quote typically includes. Contractors 20 minutes away in San Bernardino are pricing for a different set of code requirements and a different failure profile. When you compare quotes, ask whether the San Bernardino number includes re-decking, snow-load upgrades, and the mountain-access logistics; if it doesn’t, you’re not comparing the same roof.
Yes, roof replacement in Crestline requires a permit, and the inspection process is what catches undersized framing and inadequate ventilation that a casual overlay would hide. We pull the permit, schedule the inspections, and make sure the finished assembly passes. For older cabins, expect the inspector to verify the decking, nailing pattern, and underlayment before we close it up.
You should almost always replace, not overlay, an old Crestline cabin roof, because the original wood decking and undersized framing don’t meet current snow-load and uplift requirements, and overlaying hides exactly the problems you need to fix. A straight overlay is rarely a legal shortcut at this elevation, and it leaves the underlying rot in place. If your roof is old enough that you’re considering an overlay, it’s old enough that the decking underneath needs to be inspected – and in our experience, it usually needs work.
For Crestline homes, we recommend a Class A fire-rated architectural shingle with a debris-shedding profile and proper valley protection, not a flat-tile look that collects pine needles. We also spec metal valleys, ember-resistant flashing, and a ridge vent sized to actually vent the attic. The brand gets selected after we’ve looked at your specific roof – GAF, Atlas, or Tamko each have products that fit mountain conditions, and since we carry all three, we’ll tell you which one earns its price on your roof. Call (866) 942-4187 for an exact recommendation and quote – the estimate is free.
