Fast, Reliable Roof Inspection Across Lake Arrowhead
A roof inspection in Lake Arrowhead is a detailed walk of your roof and attic that tells you exactly what’s failing, what’s holding up, and what it costs to fix. Up here at 5,100 feet, that answer matters more than in the valley. Snow, ice, and high-altitude sun damage roofs faster than most homeowners expect, and you need an inspector who understands alpine conditions. When problems are found, Roof Repair in Lake Arrowhead needs to be handled by someone familiar with these mountain conditions.
Brennan Roofing Co Riverside runs inspections throughout Lake Arrowhead under the Garrison Standard: a written price before any work starts, uniformed and background-checked technicians on your property, and a 365-day guarantee on any repair we recommend and perform. Call (341) 208-3988 to schedule your Roof Inspection.
Why Brennan Roofing Co Riverside Is Lake Arrowhead’s Preferred Roof Inspection Company
What we find on Lake Arrowhead roofs is rarely what a generic inspector from down the hill would catch. We look at how your roof handles over 100 inches of annual snowfall, freeze-thaw cycles that split shingles, and UV exposure that bakes older cedar shakes into brittle kindling.
Lake Arrowhead homeowners call us because we show up inside the promised window. We don’t make you wait around guessing. Our technicians wear uniforms, pass background checks, and treat your property like someone accountable will be checking their work. Travis Oakley oversees operations and holds every inspection to the same standard, whether it’s a 1920s lakefront cabin near Blue Jay Bay or a 1980s A-frame off Highway 173.
Every inspection report tells you what we found, what it costs, and what can wait. No vague warnings, no pressure. The number goes on paper before you commit to anything.
Styles & brands we work with






Roof Inspection Companies in Lake Arrowhead
Roof Inspection Companies in Lake Arrowhead range from national chains that send whoever’s available to local crews who actually know mountain roofing. The difference shows up fast. A proper inspection up here means going into the attic, walking the decking, and checking valleys, dormers, and north-facing slopes where moss and rot hide.
A standard residential Roof Inspection in Lake Arrowhead runs $250 to $450. If you add a drone pass for steep pitches or thermal imaging for hidden moisture, expect $450 to $800. That’s the honest range before anyone asks you to commit to repairs.
Attic and Decking Evaluation
We go into the attic on every inspection. That’s where the truth lives. Spongy plywood under original cedar shakes, rusted nail heads, daylight coming through the sheathing, all of it visible before the shingles ever come off. In Lake Arrowhead’s older cabins, skipped attic checks are the single most common way homeowners get surprised by a quote that doubles once the roof is open.
Valley, Dormer, and Flashing Check
Lake Arrowhead’s mixture of lakefront cabins, A-frames, and custom timber homes creates lots of valleys and dormers. These are the highest-risk points on any mountain roof. Ice dams form in valleys every winter. Pipe penetrations around dormers get worked loose by snow load. We check each one and photograph what we find.
Commercial Roof Inspection in Lake Arrowhead
Commercial Roof Inspection in Lake Arrowhead carries a different set of demands than residential work. Lodges, restaurants, and lakefront retail properties often have low-slope or modified bitumen roofs that hold snow differently than a steep residential pitch. Standing water, ice weight, and drainage are the big three.
Commercial inspections in the Lake Arrowhead area typically run $450 to $1,200 depending on square footage and roof type. We photograph every problem area, mark penetrations, and produce a written report your insurance company or lender can actually use.
Flat and Low-Slope Roof Checks
Low-slope roofs on commercial buildings around Lake Arrowhead Village and Blue Jay accumulate snow that most residential pitches shed naturally. We check for ponding water, membrane cracks, and seam failures before spring melt finds its way inside.
Multi-Building and HOA Properties
For condo associations and multi-building properties, we schedule inspections in a single day and deliver one consolidated report. Pricing is per building, with volume rates applied when we inspect three or more structures in the same visit.
Trusted Brands We Service in Lake Arrowhead
We inspect and repair roofs built with GAF, CertainTeed, and Atlas materials most often in Lake Arrowhead, because those manufacturers dominate the mountain market here. We also work on roofs using Boral and Tamko products. We know the failure modes for each brand at altitude, and we can source local parts fast when an inspection turns up damaged flashing or failing underlayment. For older cabins with original cedar shakes, the conversation usually starts with what’s salvageable and what needs a full component swap.

AfterCommon Roof Inspection Problems We See in Lake Arrowhead Homes
- Ice-damaged original cedar shakes on north slopes. The north-facing roof gets almost no winter sun, so snow sits, melts, refreezes, and works water under the shakes. By the time you see a stain on the ceiling, the decking underneath is often far gone.
- Rotted plywood decking under moss-covered shakes. Moss holds moisture against wood for months. We’ve poked a finger through decking on more than one Lake Arrowhead cabin where the shingles looked fine from the ground.
- Failed valley flashing from freeze-thaw cycling. Old metal flashing expands and contracts through a hundred freeze-thaw days per season, eventually cracking or pulling away from the roof plane. Valleys are where most leaks start.
- Inadequate or nonexistent attic ventilation. Many 1960s and 1970s lakefront cabins and A-frames here were built with minimal ventilation. That trapped heat melts snow unevenly, which is precisely what creates ice dams.

FAQs About Roof Inspection in Lake Arrowhead
We walk the decking from inside the attic, not just from the top side. In a 1960s cabin, plywood decking that’s been wet repeatedly will feel soft, show dark staining, and may have nail heads that have pulled through. If the decking is compromised, we tell you before any shingles go on, and we write the replacement cost into your quote as a line item, not a surprise add-on. Call (341) 208-3988 to schedule the attic check.
The north-facing slope gets the least direct sunlight, so it stays damp longer. Moss takes hold there and never dries out. It does concern us, because moss holds moisture against the roofing material year-round, which accelerates rot on cedar shakes and shortens the life of asphalt shingles. We recommend treating the moss and addressing the underlying drainage before it costs you a decking replacement.
Yes, if you’re re-roofing in Lake Arrowhead, the building department expects ice and water shield on eaves, valleys, and around penetrations to current code. It’s not optional up here, and for good reason: at 5,100 feet with over 100 inches of annual snow, the membrane is what keeps meltwater out of your decking. We include it in every quote for mountain homes. No surprises later.
We check every dormer for failed pipe boot seals, cracked caulk at the transition, and nail pops that create gaps. Valleys get checked for torn or lifted flashing, shingle granule loss, and evidence that water has been running under the valley channel. On older cabins near Grass Valley and along the north shore, dormer leaks are one of the most common things we document. You’ll see it in the photos, not just in a summary line.
Ask every bidder to put the number on paper before the inspection happens, and ask what the square-foot price includes. Does it include the attic check, the valley and dormer evaluation, and written photo documentation? If a crew won’t give you a number until after they walk the roof, you’re not getting a bid, you’re getting a sales pitch. Brennan Roofing gives you a written number before any work starts, every time.
