Fast, Reliable Roof Repair Across Highland

Roof repair in Highland usually runs between $425 and $1,800 depending on what’s failing, with most leak repairs landing in the $425 – $750 range. The bigger variable here isn’t labor, it’s code: homes in the foothill neighborhoods east of Webster Street sit in CAL FIRE Very High Fire Hazard Severity Zones, which means a repair that looks simple from the curb can legally require Class A materials and compliant underlayment before the county signs off. Mercer Roofing has been handling that reality since 2000. Call (743) 200-8347 and we’ll walk you through exactly what your roof needs and what it will cost, in writing, before you commit.

Why Mercer Roofing Is Highland’s Preferred Roof Repair Company

Highland homeowners call us because they want to know who’s walking up the driveway. Every Mercer technician is background-checked, identity-verified, and arrives in a marked uniform with a photo ID badge at the door. Before they come, we send their name and photo to your phone. That’s the Threshold Verified standard, and it’s contractually required for every independently owned location in the Threshold Group family. No other roofer serving Highland’s eastside foothills does that as a matter of policy.

We also put every price in writing before work starts. No verbal estimates, no surprise add-ons after the tear-off. If you need a valley repair near Greenspot Road or a vent boot replacement off 5th Street, you’ll know the full number before our crew sets a ladder. And every repair carries a written 365-Day Done Right Promise: if the fix doesn’t hold within a year, we come back and make it right at no charge. That’s not a marketing line. It’s in the paperwork you sign.

Grant Whitlock, who leads our Highland service area, personally reviews every job file before dispatch. He’s the one who reads the inspection notes, checks the VHFHSZ map layer for your parcel, and confirms the material list matches what the permit requires. That level of local oversight is rare.

Emergency Roof Repair in Highland

Emergency Roof Repair in Highland is what you need when a Santa Ana wind event off the Cajon Pass tears shingles loose, or a branch from a foothill oak punches through a roof plane. These are not “wait until Tuesday” situations. Water is coming in, insulation is soaking, and drywall is next. Call (743) 200-8347. A live person answers, day or night. We’ll walk you through a temporary tarp if the weather’s still active and schedule a technician for the earliest available slot.

Most Highland emergency repairs run $500 – $1,100. That covers securing the breach, replacing damaged decking if the wet zone is small, installing new underlayment, and matching the shingle or tile as closely as the available stock allows. If the damage crosses into a VHFHSZ parcel, the permit may require Class A-rated material even for a patch. We tell you that on the phone, before anyone shows up.

Storm and Wind Damage Response

Highland’s position at the mouth of the Cajon Pass means wind gusts hit differently here than in San Bernardino or Loma Linda. We see shingle tabs lifted, ridge caps peeled, and occasional full sections torn off on south-facing slopes. Our crew starts with a full plane-by-plane inspection, not just the visible damage, because wind can unseal shingles twenty feet away from the obvious tear.

After any storm, we recommend photographing everything before cleanup. Your insurance adjuster will want that. We’ll help you document what we find and give you a written repair scope you can submit directly.

Leak Containment and Tarping

When a roof is actively leaking, the first step is stopping the water. In Highland’s winter rain pattern, which is heavier than the flat western Inland Empire, that sometimes means a temporary tarp secured with furring strips before any permanent repair can be attempted. Tarps hold, but they’re not a roof. We schedule the actual repair as soon as the surface is dry enough to work safely.

Flat Roof Repair in Highland

Flat Roof Repair in Highland typically costs $600 – $1,500 depending on the membrane type and how far the damage extends. Highland has a surprising number of flat and low-slope roof sections, especially on 1970s and 1980s tract homes with attached patios, carports, and room additions that were permitted under looser building codes than we have now. Those aging torch-down and rolled asphalt membranes crack, blister, and separate at the seams after decades of 105°F summers and cool mountain nights.

The issue on most Highland flat roofs is sealed-in moisture. Once water gets between the membrane and the decking, it moves sideways, so the visible crack is rarely the whole story. We probe the wet zone, open the membrane back to dry decking, and patch with compatible material, not just a can of roof cement over the bubble. If the decking is soft, we tell you before we replace it and get your written approval on the added cost.

Low-Slope Section Repair

Low-slope sections on Highland homes, typically over patios and additions, need different materials than the pitched field. Standard shingles don’t work below a 2:12 pitch. We use self-adhered modified bitumen or a compatible single-ply patch, depending on what’s already installed. Merging a low-slope patch into the shingled field correctly takes care, and we set the transition flashing so water never ponds at the seam.

Ponding and Drainage Fixes

Ponding water after rain is the quiet killer of flat roof sections on East Highland Boulevard-area homes. If water stands for more than 48 hours, the membrane degrades faster. Sometimes the fix is a tapered cricket to redirect flow to the drain. Sometimes it’s clearing debris from scuppers or replacing a crushed drain basket. We’ll tell you what’s needed and quote it plainly.

Trusted Brands We Service in Highland

We repair and install the brands Highland homes already carry: GAF, CertainTeed, Owens Corning, Atlas, and Tamko. The foothill tracts off Base Line Road have a heavy concentration of original 3-tab GAF fields and replaced CertainTeed architectural roofs. The custom hillside homes lean toward Atlas and Tamko Timberline-style profiles. Our crews are trained on each manufacturer’s installation specs, and we stock common trim, caps, and starter strips locally, so we don’t lose days ordering from a warehouse across the county. That means faster turnaround for Highland homeowners waiting on a leak fix. If your roofline uses a discontinued color, we’ll match it as closely as current inventory allows and show you the comparison before ordering.

Common Roof Repair Problems We See in Highland Homes

• Thermal-cycling shingle failure on 1960s – 1990s tract homes. Original 3-tab shingles exposed to Highland’s extreme swings, 105°F days against cool mountain nights, lose their adhesive bond and start cracking. Patching one tab usually means another fails next season. We’ll show you the difference between a localized fix and a field that’s already past its useful life.
• Valley leaks on sloped foothill lots. The custom and semi-custom homes east of Highway 330 have multiple roof planes meeting at steep valleys. Many were built before ice and water shield was standard practice, so when the underlayment paper finally breaks down, the leak shows up on the ceiling below the valley, nowhere near the damaged shingles.
• Vent boot and pipe collar failures. The rubber gaskets on plumbing vent boots crack after 12 – 15 years in Highland’s UV-heavy summers. This is one of the least expensive fixes we do, usually $350 – $500, but it’s also one of the most common causes of “mystery” leaks that only show during the winter rain months.
• VHFHSZ non-compliance discovered at inspection. We regularly repair roofs in Highland’s foothill fire zones where a previous handyman or out-of-area contractor used standard materials instead of the Class A-rated products San Bernardino County requires. The repair holds, but it’s illegal, and it gets flagged the next time a permit is pulled. We fix it right the first time, with the right materials and the paperwork to prove it.
