Fast, Reliable Roof Repair Across Highlands
A roof leak in Highlands rarely announces itself politely. It shows up as a brown stain on the ceiling after a Santa Ana wind event, or as shingle granules piling up in the gutter after a hot summer. When that happens, you need a roofer who knows Highlands, not a dispatcher three counties away. Mercer Roofing has been repairing roofs since 2000, and our crews work Highlands regularly, from the mid-century tracts off Greenspot Road to the newer builds near the foothills. Call (743) 200-8347 and you’ll get a live person, not a voicemail. We send a background-checked, photo-badged technician whose name and photo you’ll have before they arrive. In Highlands, most repairs run $350 to $1,800 depending on what we find. Some jobs are smaller. Some are bigger. We never start work without a written price.
Key Takeaways:
- Most Highlands roof repairs run $350 – $1,800; the written quote is free and fixed before any work starts.
- Every repair carries a 365-Day Done Right Promise with a written guarantee and a free second visit if the repair fails.
- We document your roof’s fire rating before we touch it, because Highlands WUI codes and insurer reassessments make that step essential.
- The technician who shows up is the same person whose name and photo we sent you, badged and in uniform.
Why Mercer Roofing Is Highlands’s Preferred Roof Repair Company
Highlands homeowners deal with a specific set of roof problems that valley-floor cities never see. The WUI fire-rating rules, the Santa Ana wind shear, the thermal cycling off the San Bernardino Mountain evenings. Our Roof Repair team walks every Highlands job with those conditions in mind. We see the same recurring failure points: ridge caps sheared off by October winds, cracked shingle mats from triple-digit days and cool nights, ponding edges on low-slope built-up roofs after heavy rain. Knowing these patterns means we can often tell you what’s happening from your first phone call and give you an honest expectation of cost before we even climb up.
Grant Whitlock leads our crews. When he dispatches to Highlands, he sends the assigned technician’s name and photo ahead of every visit. You open the door with confidence because you already know who’s standing there. Every technician is background-checked, identity-verified, and badged under the Threshold Verified standard. That’s not a gimmick. It’s the reason homeowners who worry about who they let in the house call Mercer. Our customers in Highlands consistently tell us the same thing: they appreciated knowing exactly who was coming, seeing the photo ID at the door, and having every price in writing before a single nail went in.
Metal Roof Repair in Highlands
Metal Roof Repair in Highlands usually means fixing a standing-seam or screw-down metal roof that’s been compromised at the seams, fasteners, or flashing points. On older Highlands homes, we often find corrosion around the fastener heads, worn neoprene washers, or panels that have lifted at the ridge from Santa Ana gusts. The repair involves removing the failed fasteners, inspecting the underlying underlayment, replacing seam tape or sealant where panels lap, and re-fixing the metal with fresh fasteners rated for uplift. In Highlands, expect to pay $450 – $1,900 for a typical metal roof repair. A loose seam that just needs re-sealing runs toward the bottom of the range. A section that’s creased, corroded, or pulled free of the decking runs higher.
Fastener and Seam Failures
Metal roofs fail at the connections before they fail in the panel. We check every fastener in the repair area, not just the one that backed out. If the neoprene washers are cracking high on the ridge, we replace the full run so you aren’t back up there in six months for the same leak one bay over.
Ridge and Flashing Repairs
On Highlands metal roofs, ridge caps and Z-flashing take the worst of the wind. We re-secure them with foam closures and new fasteners, and we re-tape the laps with a product rated for the mountain heat cycles we get up here. The repair is done to stay through the next wind season.
Commercial Roof Repair in Highlands
Commercial Roof Repair in Highlands usually targets flat or low-slope built-up, modified bitumen, or TPO systems on small commercial buildings: offices, churches, strip centers. Here in Highlands, we see a lot of older built-up roofs with original tar-and-gravel that’s now well past its service life. The repair typically involves finding the compromised point, removing the failed membrane or ballast, patching the substrate, and applying a new Class A-rated membrane layer that ties into the surrounding field. Expect commercial roof repair in Highlands to run $800 – $3,500 depending on the size of the repair area and the complexity of the membrane system. A simple penetration leak or seam repair sits at the lower end. A larger membrane section with wet insulation will sit higher.
Penetration and Curb Sealing
HVAC curbs, vent pipes, and drains are where most commercial roofs leak. We inspect the sealant, the pitch pockets, and the counterflashing around every penetration in the repair zone. We replace the sealant with a product suited to the freeze-thaw and heat-cycle swings Highlands gets, then we re-wrap the flashing so water can’t chase the bolts down.
Matching Class A Assemblies
This matters more in Highlands than almost anywhere else we work. A commercial roof here that gets patched with a non-Class-A product can trigger the same insurer flag that’s forcing so many re-roofs in the foothills. We always match the repair assembly to the existing fire rating, and we document it in your written scope.
Trusted Brands We Service in Highlands
Our Highlands crews work on roofs built with every major shingle brand, and we’re equipped to repair them all without improvised mismatches. We regularly service GAF and Owens Corning shingle systems, and we keep the common matching colors and accessories in stock for Highlands jobs so you’re not waiting on a special-order ridge cap while a patch sits open. We also work with CertainTeed products when the roof calls for them. The point is this: the repair should look like it belongs to your roof, not like a salvage yard found a close-enough bundle. We write the brand and the color into your quote, and the written price covers it.
Common Roof Repair Problems We See in Highlands Homes
- Wind-sheared ridge caps and starter strip. Santa Anas funnel straight down the passes above Highlands, and shingles installed in the 1960s and 70s weren’t rated for those gusts. We find ridge caps missing, lifted, or cracked along the windward sides of homes off Greenspot and the parallel streets.
- Thermal cracking on aging shingle mats. Triple-digit days followed by cooler mountain nights bake and then contract the asphalt, which cracks the shingle mat faster than valley-floor roofs. A patch that only replaces the visibly torn shingle usually leaves adjacent fatigued ones to fail within a season.
- Ponding edges on low-slope and built-up roofs. Foothill rain events shed fine sediment into gutters, clogging them and holding water against the roof edge on shallow-pitch tract homes. The repair has to clear the drainage path and re-flash the edge, or the same edge gets re-soaked in the next downpour.
- Deteriorating flashing at valleys and penetrations. The original valley metal and pipe boots on 1950s – 70s Highlands homes are aging out. We typically find cracked boots, separated valley seams, and sealant that’s lost its bond. This work is part of the repair, not an add-on.
Pricing for Roof Repair in Highlands, CA
A fair range for roof repair in Highlands is $350 – $1,800 for most single-family homes. Small leaks and pipe boot replacements sit around $350 – $500. Valley re-flashing or a ridge-cap section runs $600 – $1,200. A larger repair that involves decking replacement, drainage correction, or a Class A assembly match can reach $1,800 or beyond. What pushes a Highlands quote higher than a valley-floor city is the added cost of managing tight access and the extra material steps required by WUI fire codes. We give you the written price before any work starts, and that number doesn’t change unless you ask for additional work. Call (743) 200-8347 for a free estimate, and we’ll send someone to Highlands to look at the roof and write the number down on paper for you.

FAQs About Roof Repair in Highlands
Because Highlands sits in the Wildland-Urban Interface at the base of the San Bernardino Mountains, and that changes the materials, the documentation, and the access. WUI fire codes require Class A-rated repair assemblies, which cost more than standard patch materials. The paperwork we generate to document your roof’s fire rating is an extra step valley-floor roofers skip. And the tight lot access on Highlands streets means we often hand-carry materials to the roof instead of running a conveyor, which adds labor time. Call (743) 200-8347 for a free estimate, and we’ll show you exactly where the cost goes on the written quote.
Yes, in many cases you can repair just the damaged section, but only if we document the existing roof’s fire rating and match the repair assembly to it. Here’s the Highlands-specific part: a torn-off patch that exposes or mixes with a non-Class-A field can trigger the insurer flag that makes the whole roof uninsurable, not just the damaged square. That’s why we photograph and document your roof’s rating before we touch it, then write the scope so your insurer sees a Class A-matched repair, not a bare patch. Call (743) 200-8347 and we’ll walk through what your specific insurer is looking for.
We treat shared walls and party-wall boundaries as part of the repair scope, not an afterthought. On attached or closely-spaced Highlands homes, we protect the neighbor’s roof side with felt and edge protection, keep our ladders and materials off their property, and work during standard construction hours. We stage materials in the driveway or street-side, not in a side yard that crosses a property line. And the written quote reflects any access limitation, so you aren’t surprised by a change order later. Call (743) 200-8347 to schedule a free estimate and we’ll note the site conditions in the written scope.
Expect the repair to address drainage, not just the visible membrane damage. On Highlands low-slope built-up roofs, ponding at the edge is almost always tied to clogged gutters and sediment from the foothill slopes. We clear the drain path, re-check the edge flashing, and repair the membrane where the water has been sitting. Then we slope or re-ballast the repair so water can’t pool back in the same spot. A patch without the drainage work just gets re-soaked from the same edge in the next rain event. Call (743) 200-8347 and we’ll give you a written price that covers both steps.
Yes. We use uplift-rated fasteners and a nail pattern that’s designed for the gust loads that funnel down the mountain passes above Highlands. That means more nails per shingle and additional sealant at the ridge, not the standard valley-floor pattern. The windward side of your roof takes the worst of the force, so we inspect and reinforce the full run, not just the loose section. If the existing ridge cap or starter strip is already wind-damaged, we re-fasten or replace it as part of the repair rather than leaving a known failure point for next Santa Ana season. Call (743) 200-8347 and we’ll write the fastening spec into your quote.
