Fast, Reliable Roof Replacement Across Crestline
Roof replacement in Crestline usually runs $12,000 – $28,000 for a typical mountain cabin, depending on size, pitch, decking condition, and whether you need a Class A fire-rated assembly. Most homes here were built between 1950 and 1980, so what’s under the shingles is rarely clean. If your roof is at or past 20 years, has ice-dam staining at the eaves, or lost granules after last winter, call us at (877) 588-7942 and we’ll schedule a structured inspection before you commit to anything.
We work in Crestline weekly, from the lake side of Lake Gregory Drive up to the ridge lots off Highway 138. This is snow-country roofing, not Inland Empire flatland work, and we approach it that way: ice and water shield, snow-shedding details, and WUI fire clearance on every replacement.
Why Ridgeway Roof Repair Is Crestline’s Preferred Roof Replacement Company
We only do roofing. Every crew member who works in Crestline does roofing every day, not plumbing on Tuesday and siding on Thursday. That focus matters when you’re opening a 1960s cabin and finding skip sheathing, valley rot, or framing that was never built to current snow-load standards. Our crews have seen those conditions enough times on Crestline homes that they don’t slow the job down, and they don’t write surprises into the invoice after the fact.
Roland Cifuentes runs the company with a simple rule: document what’s found, price it in writing, and get your approval before we touch it. That’s how we handle every decking allowance, framing repair, and membrane upgrade on a Crestline replacement. We also carry materials from seven manufacturers, so when we recommend a shingle for your roof, it’s because it fits your snow load, fire zone, and budget. Not because it’s what we happen to stock.
Our customers in Crestline often tell us the inspection was the most useful part of the process. You get photos, measurements, and a straight answer about remaining roof life, so you’re deciding based on evidence, not a sales pitch.
Styles & brands we work with
Flat Roof Replacement in Crestline
Flat roof replacement in Crestline tends to run $9,000 – $18,000 on cabins and additions with low-pitch or built-up sections over porches, dormers, or mid-century flat-roof additions. These sections fail differently than pitched roofs here: snow sits on them longer, ice dams form around the drains and scuppers, and the freeze-thaw cycle at 4,600 feet separates membrane seams faster than the same roof would degrade in San Bernardino below.
When we replace a flat section in Crestline, we’re looking at three things before we quote: the condition of the decking under the membrane, whether the drains and scuppers are actually shedding water, and whether the original roof has any ice and water shield at all. Most 1960s and 1970s flat sections in Crestline have none.
Membrane Options for Mountain Conditions
We install multi-brand membrane systems rather than pushing one manufacturer. For Crestline flat sections, we typically discuss modified bitumen and TPO, because both handle standing snow and high-UV exposure better than older built-up roofs. The right membrane depends on how much foot traffic your roof gets, how long snow sits on it, and whether you have rooftop equipment.
When Resurfacing Isn’t Enough
If the decking below the membrane is soft or the insulation is waterlogged, resurfacing is a waste of your money. We’ll open the section up enough to verify what’s underneath, document what we find, and price any decking replacement as a written change order before work continues.
Roof Installation in Crestline
Roof installation in Crestline on a full replacement typically lands between $12,000 and $28,000 for the average mountain home, with new-construction installation on custom mountain builds running higher depending on roof complexity. The elevation here changes the installation standard: shingles must be rated for snow load, underlayment has to extend far enough up the eaves to stop ice dams, and ridge venting has to work with a roof that may hold snow for weeks at a time.
The biggest variable in a Crestline installation isn’t the shingle brand. It’s what’s underneath. Roofs from the 1950s through the 1970s often have 1×6 skip sheathing instead of solid plywood, and that sheathing is frequently soft at the valleys and eaves. Snowmelt sits in those low spots, and over 50 or 60 years, the wood goes. We inspect for that before we quote.
Decking Replacement and Structural Work
When a Crestline roof needs new decking, we write it into the contract as an allowance. You’ll know the per-sheet price before we start, and we’ll photograph and document every sheet we replace. If we find framing that needs attention, you get photos, a specific repair scope, and a signed change order before we touch the structure.
Snow-Country Installation Details
Every pitched roof we install in Crestline gets ice and water shield at the eave line, starter strip, and proper ridge venting as standard. We don’t treat those as upgrades. In this climate, they’re code-minimum practicalities, and skipping them is how you get ice damming and premature shingle failure on a mountain home.
Trusted Brands We Service in Crestline
We install and service products from GAF, Atlas, CertainTeed, Owens Corning, IKO, Tamko, and Boral, which means your material recommendation comes from what your roof actually needs. For Crestline’s snow and fire conditions, we often recommend GAF or CertainTeed architectural lines for steep cabin roofs, Atlas for fire-rated assemblies where WUI clearance is the priority, and Boral when homeowners want a stone-coated steel or tile profile that sheds snow differently than asphalt. We don’t stock one brand and push it on every house. We order materials for your specific roof, and our supply chain keeps Crestline jobs moving without long waits.

AfterCommon Roof Replacement Problems We See in Crestline Homes
- Ice damming at the eaves: Steep cabin roofs without ice and water shield let snowmelt back up under the shingles and into the decking. We see this on nearly every original 1960s and 70s roof in Crestline, and it’s the single biggest reason a cheap replacement fails early.
- Soft skip sheathing under old shingles: The original 1×6 sheathing on many Crestline cabins has rotten spots at the valleys and eave lines. It can’t hold new nailing patterns, so it has to come out before new shingles go down.
- Fire-damaged or undersized framing: Homes that survived past burns or were rebuilt on older framing sometimes have rafters that were never sized for current snow-load standards. When that shows up, the structural repair is a written change order, not an after-the-fact invoice.
- WUI fire-zone conflicts with snow detailing: Fire clearance rules on roof covering and eave venting sometimes push toward details that trap snow and ice at the fascia. We assemble roofs to satisfy Class A fire rating and snow-shedding at the same time, which flatland roofers often don’t have to think about.
Pricing for Roof Replacement in Crestline, CA
A full roof replacement in Crestline generally runs $12,000 – $28,000, with flat or low-pitch sections landing between $9,000 and $18,000. What moves your number: roof size and pitch, whether decking needs replacement, the fire-rating requirement on your specific lot, and whether we’re tearing off one layer or two. A 1,500-square-foot cabin with a 6/12 pitch and clean decking is a very different job from a 2,800-square-foot multi-gable home with valley rot and no ice and water shield.
We write decking and framing allowances into every Crestline contract, so you know the per-unit cost before we start. If we find something under the old shingles, you approve the price in writing before we proceed. Call (877) 588-7942 for a free estimate, and we’ll give you a line-item quote, not a lump-sum guess.

FAQs About Roof Replacement in Crestline
Because most initial quotes assume the decking and framing under the old shingles are sound, and on Crestline homes built between the 1950s and 1970s, they often aren’t. Ice damming, valley rot, and skip sheathing show up once the old roof comes off, and those are conditions no one can see from the top. We handle this by writing decking and framing allowances into the contract up front, so you know exactly what each additional repair costs before we start. If you want certainty before you commit, call (877) 588-7942 and we’ll do a structured inspection first.
Yes. Architectural shingles shed water, but they don’t stop ice damming. Ice and water shield is a membrane installed at the eave line and in the valleys that seals around nail penetrations and prevents backed-up snowmelt from reaching the decking. Every pitched roof we replace in Crestline gets it as standard, regardless of shingle brand or quality.
Your lot inside the San Bernardino National Forest Wildland-Urban Interface requires a Class A fire-rated roof assembly, which affects shingle choice, eave detailing, and venting. But because Crestline is also a snow-load zone, the fire-compliant details have to work with ice and water shield and snow-shedding, not against them. We install to both standards, because a roof that satisfies one and ignores the other fails at the margin. Call us at (877) 588-7942 for an exact assessment of your property.
Yes. Many Crestline cabins have flat or low-pitch sections over porches, dormers, or mid-century additions, and those sections fail differently than the pitched roof. We replace them with membrane systems rated for standing snow and high-altitude UV, and we inspect the decking below the membrane before we quote. If the decking is soft or the drains are damaged, you’ll know before any money changes hands.
We price the visible scope, then write an allowance into the contract for decking replacement at a fixed per-sheet rate, plus a separate framing allowance for structural issues. If we find soft sheathing or undersized rafters once the roof is open, we photograph it, document it, and get your signature on a change order before work continues. You’re never billed for something you didn’t approve in writing. For a line-item quote on your Crestline roof, call (877) 588-7942.
Ridgeway Roof Repair started with a simple idea: know what’s on the roof and under it before you ask a homeowner to spend five figures. In Crestline, that means inspecting for ice-dam damage, skip sheathing, and fire-zone code requirements before we ever write a quote. If you suspect your roof is failing, don’t wait until the snow loads hit. Call (877) 588-7942 and schedule a free inspection. From inspection to repair to full Roof Replacement, one company handles the whole job.
