Roofers in Crestline, CA
Crestline sits at 4,600 feet in the San Bernardino Mountains, and the roofs up here work harder than most. Steep pitches shed heavy snow, ice dams test every flashing seam, and mountain winds find every loose shingle. Homeowners in Crestline need roofers who understand snow load, ice and water shield, and the county’s specific mountain code requirements, not a crew running valley standards at altitude. If you’re looking for a roofer in Crestline, CA who writes the price down before any work starts and puts the guarantee in writing for a full year, call Brennan Roofing at (341) 208-3988.
Why Crestline Homes Are Different
Most of the housing stock in Crestline is mountain cabins, chalets, and custom homes that range from 1930s-era bungalows to newer construction. Steep slopes and attic spaces are common, which means roof framing and decking need a close look before any replacement goes on. A 1930s cabin often has plank decking with gaps that valley homes never see, and those gaps matter when snow sits on the roof for weeks at a time.
The climate drives most of what we do differently here. Crestline sees significant winter snowfall and high winds, and freeze-thaw cycles at this elevation band are brutal on metal flashings. Ice dams form under flashings after a warm day followed by a hard freeze, and water works its way into places it never reaches at lower elevations. Many Crestline roofs need snow brackets or snow guards to hold snow in place and let it melt gradually instead of sliding in a sheet. The county enforces strict mountain-area code requirements for snow load and ice dam protection, and those requirements differ from valley cities like Highland or Fontana. The roof has to be framed and underlayed for the mountain, not for the flatlands.
Styles & brands we work with






Our Main Crestline Services
Most calls we get from Crestline homeowners come down to three things: a roof that needs replacement, a leak that needs repair, or an inspection before winter or after a storm. Each has its own page below with local pricing and specifics.
Roofing Company in Crestline
A roof installation or replacement in Crestline starts with an assessment of the decking, framing, and snow load requirements for your specific elevation and exposure. Steep-pitch composition and metal roofs are the norm here, because both shed snow well when installed correctly. We write the full price on paper before any work starts, including any decking repair the job uncovers, and the 365-Day Done Right Promise covers it in writing for a full year. Learn about Roofing Company in Crestline.

Roof Repair in Crestline
Roof repair in Crestline usually involves ice dam damage, flashing failures from freeze-thaw cycles, or wind damage to shingles and ridge caps. Small leaks at altitude become structural problems fast, because water that gets under a shingle freezes and expands. We repair the leak, replace damaged flashing, and document what we found so you can plan ahead. The price goes on paper before we start, and if the repair fails within the year, we come back free. See Roof Repair in Crestline.

Roof Inspection in Crestline
An inspection in Crestline is most useful in late fall before snow arrives, and again in spring after melt. We check for ice dam damage, loose or missing shingles, failed sealant at flashing points, and whether snow guards are still anchored properly. You get a written report with photos and specific findings, so you know whether the roof is ready for winter or needs work first. The full inspection process is covered at Roof Inspection in Crestline.

AfterPricing for Roofers in Crestline, CA
These are typical ranges for Crestline work based on current mountain-area material and labor costs. Every job still gets a written, line-item price before any work starts, so these figures are for budgeting, not a bid.
| Service | Typical range in Crestline |
|---|---|
| Roof inspection | $200 – $375 |
| Minor roof repair (flashing, small patch) | $275 – $600 |
| Moderate roof repair (ice dam damage, multiple shingles) | $600 – $1,500 |
| Major roof repair (structural, decking, large section) | $1,500 – $4,500 |
| Full roof replacement (composition shingle) | $8,500 – $18,000 |
| Full roof replacement (standing seam metal) | $18,500 – $42,000 |
| Snow guard and snow bracket installation | $800 – $2,500 |
| Ice and water shield upgrade | $1,200 – $3,800 |
What pushes a Crestline price up is access, decking condition, and snow load requirements. A steep roof with limited staging room or a 1930s cabin with failed plank decking costs more than a straightforward tear-off on a gentle pitch. Regardless of where the number lands, it goes on paper before we start and it does not move at the door.

FAQs About Roofers in Crestline
We schedule Crestline estimates within a few business days, and repair work is typically completed inside one to two weeks depending on material availability and mountain road conditions. In winter, heavy snow can delay roof access, and we do not cut corners to beat a calendar. Call (341) 208-3988 and a live person will give you the next available window.
Many do, especially on steeper pitches and north-facing slopes where snow melts slowly and then releases in sheets. Snow guards and snow brackets hold the snow in place so it melts gradually instead of tearing off gutters and flashing. We assess this during any inspection or replacement and include it in the written price if it’s needed.
San Bernardino County enforces mountain-area code requirements for snow load, ice dam protection, and roof framing, and most full replacements in Crestline require a permit. We pull the permit, coordinate the inspection, and the final price includes permit fees. No permit costs get added later, because the price is on paper before work begins.
