Fast, Reliable Roof Repair Across Highlands
Roof repair in Highlands, CA runs $350 to $1,800 for most jobs, depending on what’s failing. A basic shingle replacement off Highway 330 costs less than a leak repair that requires pulling damaged decking near Lake Gregory. If you’re in Highlands and water is getting in, call us at (361) 320-9467 and we’ll get a technician up there the same day. We know Highlands roofs because we’ve worked on the older cabins and the post-2003 rebuilds, and we know which one you have just by looking at the street.
Why Brennan Roofing Is Highlands’s Preferred Roof Repair Company
Highlands homeowners call us because we show up. Not just that, but the same uniformed, background-checked technician you spoke to on the phone is the one who steps onto your roof. The Garrison Standard means we hand you a written price before any work starts, and that number does not move at the door. A roof repair in Highlands starts with an inspection, then a number on paper, then the work. Nothing else.
We answer the phone with a live person, around the clock. No voicemail, no callback queue. When you’re looking at water coming through the ceiling on a January night at 5,000 feet, that matters. Our Highlands reviews mention the same things repeatedly: we showed up when we said we would, the price stayed where we said it would, and we left the job site cleaner than we found it. Travis Oakley holds every technician to that standard on every single call.
Dispatch for Highlands is coordinated from our Los Angeles office, but the crews serving Highlands work this area regularly. They know which roads ice over first, which permits the fire code triggers, and which neighborhoods still have original mid-century shake under the reroofs.
Commercial Roof Repair in Highlands
Commercial Roof Repair in Highlands usually means low-slope or flat surfaces on the small retail and storage buildings scattered along the mountain roads, plus a handful of church and community structures. These roofs fail differently than residential. Standing water after snowmelt, failed membrane seams, and flashing separations at rooftop equipment are the big three. In Highlands, a commercial roof repair typically runs $900 to $3,500 depending on the membrane type and how much of the field needs attention.
Flat Roof Patch and Membrane Repair
Older modified bitumen or TPO on flat roofs in Highlands takes a beating from UV at elevation. Seams open, water pools, and the freeze-thaw cycle turns small cracks into active leaks. We cut out the failed section, inspect the insulation below, and patch with compatible material so the repair holds.
Drainage and Scupper Repair
Snowmelt has to go somewhere. When the drains or scuppers on a Highlands commercial roof are clogged or improperly flashed, water backs up under the membrane and leaks show up far from the source. We clear the path, re-flash the penetration, and make sure water leaves the roof instead of sitting on it.
Roof Leak Repair in Highlands
Roof Leak Repair in Highlands is the call we get most often between November and April, when snow sits on roofs and meltwater finds every weak point. A leak repair here costs $450 to $1,600 on average. The job means locating the actual entry point, which is rarely where the ceiling stain is. Water travels along rafters, follows the decking, and drips ten feet from where it got in. Our leak repair starts with tracing the path, not just caulking the first crack we see.
Flashing and Vent Boot Repair
Flashing around chimneys, skylights, and roof-to-wall transitions is where most Highlands leaks start. High winds at elevation work the metal loose, and UV bakes the sealant until it cracks. We pull the old flashing, inspect the underlayment below, and re-install with proper lap and sealant.
Vent boots are another common culprit. The rubber collar around plumbing vents degrades from sun exposure at 5,000 feet faster than it does in the valley. When it splits, water follows the pipe straight into the attic. A vent boot replacement is one of the cheaper roof repairs in Highlands, usually $175 to $400, and it stops a surprising percentage of active leaks.
Valley and Drip Edge Repair
Roof valleys channel a lot of water. When the metal valley flashing corrodes or the shingles along the valley develop cracks from snow load, leaks show up along interior walls. In Highlands, valley repair often means replacing failed ice and water shield underneath, not just re-shingling the surface. Drip edge comes loose from wind and expansion, and water wicks back under the fascia and behind the gutter. We re-secure or replace it before it causes rot.
Trusted Brands We Service in Highlands
We install and repair materials from GAF, CertainTeed, and Owens Corning, and we stock common components locally so Highlands repairs don’t wait on a parts truck from down the hill. Whether your home has architectural shingles that need matched replacement or you’re weighing a full repair on a post-fire rebuild, we’ll walk through the options plainly. Shingle selection matters up here: Class A fire rating and wind rating are not optional at this elevation. We’ll show you what’s on your roof, what we recommend, and what it costs before you commit.
Common Roof Repair Problems We See in Highlands Homes
- Ember-resistant vent violations. The Highlands fire code requires Class A roofing and ember-resistant vents. Out-of-area crews often reuse the old ridge vent or skip vent screens entirely, and the repair fails inspection. We see this on both old cabins and the mid-2000s rebuilds.
- Snow-damaged tiles on post-2003 rebuilds. Many homes rebuilt after the Old Fire used lightweight concrete or clay tile. Snow load and freeze-thaw cycles crack those tiles, and the crack often gets mistaken for a shingle problem. The real fix is tile replacement plus underlayment repair.
- UV-cooked sealant and lifted drip edge on original cabins. Mid-century cabins in Highlands sit fully exposed to high-elevation sun. Sealant dries out, drip edge pulls loose in high wind, and water wicks behind the flashing instead of showing up as an obvious leak. Homeowners see a small water stain and don’t realize the flashing has been failing for a season.
- Improperly flashed roof penetrations. Chimneys, plumbing vents, and exhaust fans on Highlands homes take direct hits from wind-driven rain and snow. When the flashing is underlapped or uses the wrong sealant for mountain temperatures, leaks follow. We re-flash every penetration we touch, even if it’s not the primary repair.
Pricing for Roof Repair in Highlands, CA
Here’s what Highlands homeowners can expect. Shingle replacement runs $350 to $900 for a typical repair area. Flashing repair runs $400 to $1,100 depending on the penetration. Vent boot replacement runs $175 to $400. Valley repair runs $600 to $1,400 when it includes new ice and water shield. Flat roof patching runs $900 to $2,500. Full leak repair runs $450 to $1,600. What moves the price is what we find when we open the roof: rotted decking, failed underlayment, or a fire-code violation that needs correction. On a repair call off the steep-pitch rebuilds near Lake Gregory, our crew opened a ridge section on a mid-2000s Class A asphalt roof and found the plywood decking soft where a previous valley roofer had reused the old ridge vent instead of installing an ember-resistant one. We pulled the damaged decking, replaced the failed ice and water shield at the valley, re-flashed the penetrations, and set new ridge vent with a proper starter strip. The homeowners had a written scope and approved price before we cut anything, which is the only way a job like that stays predictable.

FAQs About Roof Repair in Highlands
Yes. Highlands sits in the San Bernardino Mountains, and the local fire code mandates Class A roofing and ember-resistant vents on any roof work that touches the field, ridge, or venting. If your repair involves replacing shingles, ridge vent, or vent screens, those components must meet the code. We handle this as standard practice, not an upsell. Call (361) 320-9467 for a written quote that includes code-compliant materials.
The rebuilds that went up after the Old Fire and bark beetle losses are now 18 to 22 years old, and many used lightweight concrete or clay tile that cracks under snow load and freeze-thaw cycles. The tile itself might look fine from the ground, but the underlayment below can be failing. A roof that age at 5,000 feet is due for real inspection. We give you a straight answer on what’s left in the roof, not a scare tactic.
Yes. Original mid-century cabins in Highlands often still have wood shake or partial shake under later repairs. Wood shake behaves differently under snow, dries differently, and has different fire-code implications than architectural asphalt. Repairing a wood shake roof safely usually means replacing individual shakes and checking the flashing courses, which takes more time. We’ll tell you what’s actually on your roof and what the repair involves before we quote it.
We inspect first, then write the scope and the price on paper before we touch anything. If we open the roof and find rotted decking, failed underlayment, or a fire-code violation the previous roofer skipped, we stop, show you photos, and get written approval on the change before we continue. No one on a Brennan Roofing job proceeds on a handshake. That’s the Garrison Code, and it’s the same on every repair in Highlands. Call (361) 320-9467 to schedule your free estimate.
Most Highlands callers get a technician on site the same day or next morning, depending on weather and road conditions. Snow and ice on Highway 330 or the roads near Lake Gregory can slow response in winter, but we’ll give you a realistic window when you call. Live person, real answer, no script.
