We’ve been climbing Chino Hills roofs since 1984. We know the terraced hillside lots off Grand Avenue, the wind-exposed ridge lines near Chino Hills State Park, and the concrete tile roofs that look fine from the driveway while the underlayment beneath them turns to dust. Pete Navarro built Ridgeline Roofing Co. on the idea that a roof should be fixed once and fixed right - no runaround, no paperwork battles, no contractor who disappears before the warranty matters. When you call us, a live person answers. Day or night. Weekend or holiday. That’s how we’ve operated for over 42 years, and it’s not changing.
Why Ridgeline Roofing Co. Is Chino Hills’s Preferred Roof Repair Company
Chino Hills homeowners remember who shows up and who doesn’t. We’ve earned our reputation here one roof at a time - from the master-planned communities built during the 1985-2005 boom to the custom homes on the steepest grades near the state park boundary. Our technicians are background-checked, uniformed, and trained to document every inspection with photos from your actual roof, not a sales pitch in your driveway.
Our 90-Day Done Right Promise means exactly what it says: if it’s not right, we come back and make it right. No forms to fill out, no arguing, no runaround. The number on your estimate is the number on your invoice. We don’t believe in surprises.
Phones are staffed by a live person 24 hours a day, seven days a week - including the middle of a storm when a dislodged ridge cap is letting water into your attic. Most repairs are completed in a single visit because we stock parts for the seven manufacturer lines we install: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral.
We hire local crews and train apprentices into journeymen. We’re not storm chasers in unmarked trucks. We’re the company that plans to be here in thirty years, standing behind the work we did today.
Our Roof Repair Services in Chino Hills
Leak Repair in Chino Hills
Leaks in Chino Hills rarely come from broken concrete tiles. The real culprit, in home after home, is the original 30-lb felt underlayment installed between 1985 and 2005 - now brittle, cracked, and wicking moisture into the sheathing while the tiles above it look perfectly intact. We’ve inspected hundreds of these roofs across Los Serranos and Vellano. Homeowners point to a water stain on the ceiling and expect a quick tile swap. What we find is underlayment that crumbles at the touch. Our leak repair starts with honest diagnosis: we photograph the damage, show you what we’re seeing, and explain whether a targeted repair or full underlayment replacement is the actual fix.

Flashing Repair
Chino Hills funnels Santa Ana wind events across exposed hilltop homes, and the damage shows up first in the flashing. Ridge caps lift. Valley flashing peels back. The metal components that channel water away from joints and penetrations take the brunt of 60-plus mph gusts. We repair and replace flashing with proper overlap and fastening that holds against these wind loads. On homes near Chino Hills State Park, we also ensure all materials meet Class A fire ratings required by San Bernardino County’s WUI code. It’s extra work. It’s necessary work. We don’t cut corners on it.

Underlayment Replacement
This is the repair Chino Hills homeowners don’t see coming. The field vignette we encounter regularly: a steep hillside home in Los Serranos, a leak reported, intact concrete tiles overhead, and underlayment beneath them that has turned to brittle shards. We remove the tiles carefully, replace the failed 30-lb felt with synthetic underlayment, apply Class A fire-rated material where WUI codes require it, and reinstall the original tiles. The job is larger than expected. The alternative - leaving brittle underlayment in place - means the leak returns, probably worse, and the sheathing beneath it rots. We walk you through what we’re finding before we proceed. No surprises.

Shingle Replacement
While concrete tile dominates Chino Hills, some homes in the area - particularly additions and outbuildings - carry asphalt shingles. Our shingle replacement uses matching materials from GAF, CertainTeed, or Owens Corning, installed to manufacturer specifications that preserve your existing warranty coverage. We match color and texture to the extent possible, and we always inspect the decking beneath for moisture damage before laying new shingles. A proper shingle job in Chino Hills’s 100°F summer heat requires attention to ventilation and underlayment that cheaper crews often skip.

Flat Roof Patch
Flat and low-slope roofs on Chino Hills patio covers, casitas, and modern home additions require different materials and techniques than pitched tile roofs. We patch with compatible membranes - TPO, modified bitumen, or built-up roofing - sealed at edges and penetrations to handle the thermal expansion that inland heat creates. Every flat roof patch includes inspection of the underlying slope and drainage, because standing water in Chino Hills’s occasional winter storms will find any weakness.

Vent Boot Repair
Plumbing vent boots crack and separate from pipe penetrations over time, accelerated by UV exposure on Chino Hills’s south-facing slopes. We replace failed boots with properly sized, weather-tight units that match your roof material - never the one-size-fits-all rubber caps that last two seasons. Each repair includes inspection of surrounding underlayment, since vent areas concentrate both heat and moisture.

Valley Repair
Valleys channel the most water on any roof, and on Chino Hills’s multi-pitch hillside homes, they do it under the most stress. Original valley metal from the 1990s often shows corrosion where coastal salt air has reached inland, and Santa Ana winds lift improperly secured valley flashing at the edges. Our valley repair removes damaged material, inspects the underlayment beneath, and installs new valley metal with proper width, overlap, and fastening for your roof’s pitch and exposure.

Common Roof Repair Problems We See in Chino Hills Homes
- Silent underlayment failure on 1985-2005 concrete tile roofs. The tiles look fine. The 30-lb felt beneath them doesn’t. UV and thermal cycling have turned it brittle, and it’s wicking moisture into sheathing. This is the most common misdiagnosed problem we encounter in Chino Hills.
- Santa Ana wind damage to ridge caps and valley flashing. Exposed hilltop homes near Chino Hills State Park see repeated wind events that lift and dislodge these critical components. The damage is often progressive - one loose ridge cap becomes ten.
- Corrosion of metal fasteners and flashings from coastal salt air. Chino Hills sits far enough inland that homeowners don’t think salt air reaches them, but prevailing winds carry corrosive moisture that attacks metal roof components years faster than in Ontario or Pomona.
- Complex multi-pitch geometries on terraced hillside lots. Steep grades, multiple roof planes, and limited staging access make even straightforward repairs more labor-intensive than comparable work in flat Inland Empire cities. Safety rigging and skilled crew coordination are essential.

What moves you within these ranges: roof pitch and accessibility, the extent of hidden damage we find after tile removal, and whether WUI fire-rated materials are required for your location. Steep hillside lots with limited staging - common in Vellano and the upper reaches of Los Serranos - add labor hours for safety setup. We quote upfront, before work begins. The number we give you is the number you pay. Call (844) 563-1816 for a free estimate - we’ll inspect, photograph, and explain exactly what your roof needs.

FAQs - Roof Repair in Chino Hills
Yes, and in Chino Hills it’s the most likely cause. Concrete tiles installed during the 1985-2005 building boom typically outlast the 30-lb felt underlayment beneath them by decades. We’ve inspected countless homes in Los Serranos and Oak Tree Downs where tiles looked perfect from the street while the underlayment had turned brittle and was wicking water into the sheathing. The only way to confirm is a physical inspection with tile removal in the leak area. Call (844) 563-1816 - estimates are free, and we’ll show you photos of what we’re finding.
Yes, for homes in zones bordering Chino Hills State Park and other WUI-designated areas. San Bernardino County code requires Class A fire-rated roof assemblies in these locations, which affects both full re-roofing and substantial repairs involving underlayment replacement. We specify and install Class A materials where required, and we handle permit documentation as part of the job. Not every Chino Hills home falls under WUI rules - we verify your property’s designation during our initial inspection. Call (844) 563-1816 and we’ll check your address.
Santa Ana winds funnel through Chino Hills with particular intensity on exposed hilltop and ridgeline homes, dislodging ridge caps, lifting valley flashing, and driving debris that cracks tiles. Wind damage is often cumulative - one season loosens a component, the next tears it free. We inspect for wind damage even on calls that start as leak complaints, because the real source is often lifted flashing that water follows inward. Our flashing repair includes fastening methods rated for these wind loads. Call (844) 563-1816 after any major wind event - we’ll check for damage before the next rain turns it into a leak.
Chino Hills sits in an inland bowl, but prevailing winds still carry salt-laden moisture from the coast - enough to accelerate corrosion on metal components including garage-door springs, hinges, and fasteners compared to drier inland cities like Ontario or Pomona. The effect is real but less dramatic than at the beach. If you’re seeing premature spring failure, it’s worth checking whether your garage faces the prevailing wind direction or sits in a canyon that funnels marine air. For your roof, the same salt air attacks metal flashings and fasteners, which is why we inspect these components carefully during every Chino Hills repair. Call (844) 563-1816 for a full roof and garage-door hardware inspection.
Yes. Chino Hills’s terraced hillside lots create complex multi-pitch roof geometries that demand more labor, specialized safety rigging, and careful staging than comparable work on flat terrain. A repair that takes three hours in Ontario can take five or six on a steep Vellano lot with limited access. We account for this in our upfront pricing - no surprise add-ons after we’re on site. The complexity also means we spend more time on proper underlayment installation at valleys and pitch transitions, where water concentrates and leaks start. Call (844) 563-1816 for an exact quote based on your roof’s specific configuration.
