Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Lake Arrowhead
Lake Arrowhead roofing is not like roofing in Riverside or San Bernardino. At 5,100 to 5,800 feet, the homes here face snow, ice, wildfire embers, and UV exposure that valley roofs never see. If you need a Roofing Company that actually understands mountain conditions, Mercer Roofing coordinates local crews that serve Lake Arrowhead directly, with dispatch from the Inland Empire office. A typical roof repair in Lake Arrowhead runs $450 – $1,600, and a full re-roof on a cabin-style home generally falls between $14,000 and $32,000 depending on decking condition. Call (743) 200-8347 and a live person answers, day or night.
Why Mercer Roofing Is Lake Arrowhead’s Preferred Roofing Company
Homeowners in Lake Arrowhead tell us the same thing: they’ve had valley contractors come up the mountain, miss the ice and water shield at the eaves, and disappear when the first winter leaks appear. We don’t do that. Every Mercer technician is background-checked, identity-verified, and arrives in a marked uniform with a photo ID badge at the door. Before they arrive, we send their name and photo. That’s the Threshold Verified standard, and it matters when you’re opening your door to someone at a mountain home that may sit empty for weeks at a time.
Grant Whitlock leads our team, and he holds every job to the same standard: a written price before any work starts, and a written guarantee on every repair. If a repair fails within 365 days, we return and make it right at no charge. That’s the 365-Day Done Right Promise, and it applies to every job. Lake Arrowhead homeowners regularly mention the badge-at-the-door practice as the reason they called us instead of the lowest bid.
Residential Roofing in Lake Arrowhead
Residential Roofing in Lake Arrowhead almost always means one of two things: a repair on an aging cabin roof, or a full replacement that brings a 1920s-to-1970s home up to current fire and snow code. The difference from down the hill is structural. These steep pitches were designed to shed snow, not just look alpine. That means decking, underlayment, and fastener patterns all have to be specified for snow load and ice cycling, not just cosmetic wear.
Full Re-Roofs on Mountain Cabins
A full re-roof on a Lake Arrowhead cabin typically runs $16,000 – $30,000. The range depends on what the tear-off reveals. Many of these homes still have original 1×6 skip-sheathing that has been wet for decades. If we have to replace decking with 5/8-inch plywood, that’s material and labor that a bidder who hasn’t inspected the roof will miss. We write the price after inspection, not before, and it stays fixed.
Repairs That Actually Hold
Most repairs we do in Lake Arrowhead are $450 – $1,600. That covers everything from ice-dam leaks at the eaves to flashing failures around a chimney or skylight. The key here is cold-climate detailing. A valley crew will caulk a leak and leave. We trace the water path, replace the failed flashing or underlayment, and write the guarantee. If it leaks again within 365 days, the second visit is free.
Roof Maintenance in Lake Arrowhead
Roof Maintenance in Lake Arrowhead is not optional. Between snow season and wildfire season, a mountain roof takes more abuse in five years than a valley roof takes in twenty. We recommend an inspection every two years for most homes, and annually for cabins built before 1980. A maintenance visit runs $250 – $500 depending on what we find and what needs sealing, tightening, or clearing.
Seasonal Inspections
We look at the things that fail quietly: valley metal, step flashing, pipe boots, and the eave line where ice dams form. In this snow zone, San Bernardino County code requires ice and water shield at the eaves. Older cabins built before that code often have none, and we can usually identify the problem before the ceiling stain appears. That’s the whole point of maintenance up here.
Clearing Debris and Ember-Ready Upkeep
Pine needles and duff collect on Lake Arrowhead roofs faster than anywhere in the basin. That buildup holds moisture against shingles and becomes a fire hazard during red flag days. A maintenance visit includes clearing debris, checking gutter fasteners, and confirming the roof assembly still meets Class A requirements. Simple work, but it prevents expensive water damage and keeps the home defensible against ember cast.
Trusted Brands We Service in Lake Arrowhead
We install and repair GAF, CertainTeed, and Owens Corning shingle systems, and we keep common architectural shingle stock accessible for Lake Arrowhead jobs so a small repair doesn’t wait on supply chain delays. On re-roofs, we typically specify GAF Timberline HDZ or comparable CertainTeed Landmark systems assembled to Class A fire standards. The brand matters, but the assembly matters more here; a premium shingle over missing ice and water shield is still a leaking roof. We get both right.
Common Roofing Problems We See in Lake Arrowhead Homes
- Relatively new asphalt roofs leaking at the eaves. A valley contractor installed shingles without ice and water shield at the eave line, which San Bernardino County code requires in this snow zone. The shingles look fine; the underlayment detail was never there.
- Original wood shake roofs that are now non-compliant. Hundreds of 1920s – 1970s cabins in Lake Arrowhead still have wood shake or shingle roofs that are functionally banned under the Very High Fire Hazard Severity Zone mandate. Tear-off and Class A replacement is often the only legal path.
- Rot and hidden water damage in the decking. Freeze-thaw cycles at this elevation force water into any gap, and a shake roof that has been leaking for years has usually wrecked the skip-sheathing underneath. You won’t know until the tear-off, which is why a fixed price written before inspection is a trap.
- Improvized flashing around chimneys and skylights. On architect-specified homes, the chimney and skylight detailing has to be coordinated before dry-in. When it’s not, the crew improvises, and the details get torn back out to match spec. That’s wasted money that a written scope prevents.
Pricing for Roofing Company in Lake Arrowhead, CA
Roof repairs in Lake Arrowhead run $450 – $1,600 for most jobs. A full re-roof on a typical cabin or mountain home runs $16,000 – $30,000, with the higher end reflecting plywood decking replacement and complex flashing work. Metal roofing and specialty tile systems run higher, often $22,000 – $45,000 depending on profile and the condition of the existing structure. What changes the number fastest is decking condition, ice and water shield coverage, and access. Steep pitches and snow country drive time both add real cost. What doesn’t change is this: we write the price before work starts, and it stays fixed. No change orders unless you approve a scope change in writing first. Call (743) 200-8347 for a free estimate.

FAQs About Roofing Company in Lake Arrowhead
Because San Bernardino County code and California’s Very High Fire Hazard Severity Zone standards don’t allow a Class A shingle to be installed over a combustible wood shake base, and the uneven shake surface creates voids that compromise the new roof’s wind and fire rating. The shake must come off, the decking inspected and usually replaced, and the new assembly installed from scratch. Call (743) 200-8347 and we’ll walk you through what your specific roof needs.
Ice and water shield is a self-adhering underlayment membrane that seals around fasteners and prevents water from backing up under shingles when ice dams form at the eaves. It’s required in Lake Arrowhead’s snow zone because freeze-thaw cycles create those dams routinely, while valley roofs never see them. If your newer asphalt roof is leaking at the eaves, this is the most likely missing detail. Estimates are free at (743) 200-8347.
For GAF, CertainTeed, or Owens Corning architectural shingles, most orders are ready within 7 – 14 days, but specialty profiles or tile systems can run 4 – 8 weeks. The real scheduling variable isn’t the shingle order; it’s the decking inspection after tear-off. If we find rotted plywood, that material gets ordered the day it’s discovered. We build that into the schedule up front so you’re not surprised.
A roofing square is 100 square feet of roof area, and every legitimate quote is built on square count plus material spec plus decking allowance. A cabin roof with 22 squares at $650 – $900 per square for architectural shingle replacement lands around $14,000 – $20,000 before decking. The quotes that look cheap usually omit plywood replacement or ice and water shield. We’ll show you the line items so you can compare honestly. Call (743) 200-8347 for a written quote.
Almost always, the original installer skipped the ice and water shield at the eaves, and the first cold winter created an ice dam that backed water under the shingles. The shingles themselves are fine, but the cold-climate underlayment was never installed, so the leak returns every freeze-thaw cycle. We see this constantly on Lake Arrowhead re-roofs done by valley crews. The fix is local: we remove the lower courses, install ice and water shield properly, and re-lay the shingles. Call (743) 200-8347 for an exact quote.
