Fast, Reliable Roofing Company Across Crestline
Roof replacement in Crestline runs $14,000 to $32,000 on average, and the biggest driver isn’t shingle brand – it’s what’s hiding under your old roof. A 1950s A-frame off Lake Gregory Drive presents very different framing questions than a 1980s conventional home near Crestline Drive. Our Roofing Company team works the mountain every week, so we know what freeze-thaw does to eaves up here and what the fire marshal is going to ask about. If you’re reading this from a cabin that’s been in the family since before anyone talked about snow load, call (743) 200-8347. We’ll walk the roof with you and tell you exactly what you’re looking at.
Why Mercer Roofing Is Crestline’s Preferred Roofing Company
Grant Whitlock leads our Crestline work personally, and he’s the one who answers your questions before any crew shows up. Around Crestline, homeowners tell us the same thing: they want to know who’s walking up the driveway. We send the technician’s name and photo before the visit. They arrive in a marked uniform and present a photo ID badge at the door. No guessing. No wondering.
Our customers in the San Bernardino Mountains consistently mention two things in reviews: the written price before work starts, and the fact that a live person answers the phone at 2 a.m. when a storm just blew a section of flashing loose. Dispatch is coordinated from our Inland Empire office, but the crews live here and service Crestline directly. We’re not routing a truck up from the valley and hoping the driver knows what an ice dam looks like.
Every repair includes a written guarantee, and we back it with our 365-Day Done Right Promise. If the work we did isn’t right within a year, we make it right. It’s written down, not implied.
Metal Roof Installation in Crestline
Metal Roof Installation in Crestline makes more sense than almost anywhere in Southern California, because standing-seam and stone-coated steel panels give you a Class A fire-rated assembly and a smooth surface that sheds snow instead of holding it. A 1,200-square-foot cabin roof in Crestline typically runs $16,000 to $28,000 for metal, depending on panel profile, insulation, and what we find when the old roof comes off. Unlike asphalt shingles, metal won’t host moss from the ponderosa canopy, and it won’t crack under freeze-thaw the way tile can.
What Goes Under the Metal
On a Crestline metal roof, what’s underneath matters more than the panel itself. We install a high-temperature ice and water shield at the eaves, new underlayment, and verify the decking is solid before the first panel goes down. If the cabin framing can’t carry the snow load, adding a metal roof won’t fix that – and we’ll tell you before you’re paying for tear-off twice.
Fire Code and Snow Load Together
Here’s the thing most valley roofers don’t deal with: Crestline sits in a state-designated Very High Fire Hazard Severity Zone, so your roof assembly must meet Class A fire-rated material standards. But you also sit at 4,500 feet, where 3 to 5 feet of snow in a season is normal. If the original cabin rafters were never engineered for that weight, the metal roof you’re picturing needs structural work first. We check before we quote, not after.
Residential Roofing in Crestline
Residential Roofing in Crestline starts with an honest look at what your specific house needs, not a generic sales pitch. Most homes here fall into two camps: mid-century cabins with aging decking and questionable framing, and newer builds where the original roof was done quickly and cheaply. A full residential roof replacement on a typical 1,200 to 1,800-square-foot Crestline home runs $13,500 to $26,000 for architectural shingles. Every job gets a written, line-item price before we touch anything.
When It’s Time to Replace
If your roof is over 20 years old and you see granule loss in the rain gutters or daylight peeking through the attic planking, get an inspection. In Crestline, the pine canopy keeps roofs damp, which means shingles can fail from underneath even when the top layer still looks acceptable. Waiting usually drives up the cost, because saturated decking is a near-standard line item on older cabins rather than an occasional surprise.
Shingle Brands We Install Up Here
We install Atlas, Tamko, and GAF shingles on Crestline homes, all manufacturer-recognized and Class A rated when installed over the right assembly. We’ll show you the difference in granule retention and wind resistance for a mountain elevation like this, and we’ll tell you which one we’d put on our own place up here. The answer changes depending on whether your roof faces the lake or sits under heavy tree cover.
Trusted Brands We Service in Crestline
Our crews work weekly with GAF, Atlas, and Tamko systems, all of which hold up under Crestline’s particular combination of snow and shade. Because we service the mountain regularly, we keep common flashing, underlayment, and ridge materials in local stock, so a repair doesn’t stall waiting on a valley delivery. We also service existing CertainTeed, Owens Corning, IKO, and Boral roofs, and we’ll match your existing system when a partial replacement makes sense.
Common Roofing Company Problems We See in Crestline Homes
- Saturated decking on part-time cabins: A roof that sat through last winter’s snow and spring melt without anyone checking it often has fully saturated decking by the time we get there. On a 1962 A-frame off Lake Gregory Drive, our crew tore off legacy wood shake to find 4×8 sheets of sheathing that came apart in our hands.
- Undersized rafters under Class A assemblies: Many original A-frames and mid-century cabins were framed with 2×4 rafters that never anticipated the weight of modern fire-rated roofing materials. When we add architectural shingles or metal over new sheathing, that framing sometimes needs sistering, and the permit forces the conversation we’d want to have anyway.
- Ice damming at the eaves: Freeze-thaw cycles in a Crestline winter push meltwater under the shingle edge, where it refreezes and lifts everything above it. Without ice and water shield installed at the eaves, that’s a leak by spring.
- Legacy wood shake non-compliance: Many original Crestline roofs are wood shake or composition that no longer meets the Very High Fire Hazard Severity Zone material requirements. Selling the cabin, getting insurance, or doing any permitted work triggers the need to bring the roof to a Class A assembly.
Pricing for Roofing Company in Crestline, CA
A straight re-roof with architectural shingles on a standard 1,200-square-foot Crestline cabin runs $13,500 to $20,000. Metal runs $16,000 to $28,000. Flat or low-slope sections common on A-frames run $14 to $22 per square foot. What moves the number here is structural: if the decking is saturated or the rafters need sistering for snow load, expect another $3,000 to $9,000 depending on how much framing we’re replacing. You’ll see every allowance in writing before work begins, and if we uncover something structural after tear-off, we stop, document it, price it, and get your written approval before we proceed. Estimates in Crestline are free. Call (743) 200-8347 and we’ll give you a real number, not a range we hope you’ll accept.

FAQs About Roofing Company in Crestline
A Crestline roof replacement typically runs 25-40% more than the same footprint in San Bernardino, and the reason is structural: San Bernardino doesn’t require a Class A fire-rated assembly or snow-load engineering. In Crestline, we often have to sister undersized cabin rafters, replace saturated decking, and install ice and water shield at the eaves before the first shingle goes down. Valley roofs skip all of that. Call (743) 200-8347 for a line-item quote on your specific roof.
We inspect before we quote, and we write structural allowances into the contract for the things we know are common in 1940s to 1970s Crestline cabins: undersized rafters, rotted decking, and non-compliant fire assemblies. If we find something after tear-off that we didn’t anticipate, we stop work, show you photos, give you a written price, and get your signature before we proceed. No change orders that you didn’t approve. Estimates are free – call (743) 200-8347.
Yes. Every Crestline roof we install gets ice and water shield at the eaves and in any valley, because freeze-thaw cycling here creates ice damming that standard underlayment doesn’t stop. It’s the first line of defense against the leak that shows up in March after a heavy snow year. We include it in every replacement quote.
An unmonitored Crestline cabin roof can fail through an entire winter before anyone notices. When we finally get on the roof, we commonly find saturated decking or collapsed sheathing that a quick spring inspection would have caught early. If you can’t be up here during storm season, have us do an honest inspection now and again in late fall. The repair we do today is cheaper than the decking replacement we’ll do next June.
Yes, we install metal on A-frames in Crestline regularly, and standing-seam or stone-coated steel meets the Class A fire-rated assembly requirement for the Very High Fire Hazard Severity Zone. The honest part is that many old A-frame rafters need structural reinforcement before the metal goes on, because they were never sized for snow load plus a metal roof. We’ll tell you if yours does, and we’ll give you the framing number in writing before you commit to anything. Call (743) 200-8347 for a free estimate.
