Call (877) 367-1429 and a live person will answer, any hour.
Pomona sits in a tough spot for roofs. That inland valley bowl at the base of the San Gabriel Mountains traps heat that coastal cities never see, while the northern foothills fall inside LA County’s High Fire Hazard Severity Zones. Your neighbor in Ontario might get away with standard shingles. You might not. We’ve been climbing Pomona roofs since 1984, and we know which codes apply to which slope, which neighborhood, which ZIP.
Why Ridgeline Roofing Co. of California Is Pomona’s Preferred Roof Replacement & Installation Company
We’ve replaced roofs on Pomona homes in 91767, 91768, 91769, and 91797 for over four decades. Not from a satellite office in Phoenix. Not chasing the last storm. Our trucks roll from Los Angeles County yards, and our journeymen have worked the same Pomona streets long enough to remember which houses on Via Verde had the original ’80s low-slope membranes fail in the same El Niño year.
Our reviews from Pomona homeowners mention the same things: we show up when we say, the estimate matches the invoice, and Cole Drummond’s 90-Day Done Right Promise means something. One homeowner on North Garey Avenue put it plain - “They didn’t try to sell me what I didn’t need, and when the inspector flagged a vent detail, they were back the next morning. No argument, no paperwork.”
Live phones, 24/7. Background-checked, uniformed technicians. Photo-documented inspections from your actual roof, not the driveway. That’s the standard we hold for work done in our own mother’s home, and it’s the standard we bring to yours.
Our Roof Replacement & Installation Services in Pomona
Tile Roofing
Pomona’s northern foothills and historic districts are thick with clay and concrete tile roofs - original Spanish Revival installations on 1920s bungalows, mid-century Mediterranean revivals, and newer concrete tile on hillside builds. Here’s the local reality: many of those original tiles were fastened before Santa Ana wind standards existed, and decades of 105°F thermal cycling have opened hairline cracks you can’t spot from the street.
We recently replaced an original 1940s Spanish Revival roof on a property near Lincoln Park Historic District where the old clay tiles had been improperly fastened; we installed new Class A fire-rated Boral concrete tiles with heavy-duty fasteners to meet fire code and withstand Santa Ana wind uplift. In Pomona’s foothills neighborhoods, LA County Fire Hazard Severity Zone designations mandate Class A fire-rated roofing on all permitted re-roofs, a requirement that does not apply to many neighboring valley-floor cities like Ontario or La Puente. We handle the permit pull, the fire marshal coordination, and the structural load verification - because a tile swap without code compliance is a failed inspection waiting to happen.

Asphalt Shingles
Standard 3-tab asphalt shingles blister and curl prematurely under Pomona’s extreme 105-110°F summer heat, leading to leaks within 5-7 years - a degradation rate noticeably faster than coastal LA. We see this constantly in south Pomona and Phillips Ranch, where tract homes from the ’70s and ’80s got economical shingles that simply weren’t spec’d for inland valley UV exposure.
We install GAF and Atlas architectural shingles rated for extended high-temperature performance, with proper attic ventilation designed for Pomona’s thermal load. The price on your estimate is the price on your invoice. No surprises, no substitutions.

Metal Roofing
For Pomona’s acreage properties and foothills homes with detached workshops, metal roofing solves two problems at once: Class A fire rating for code compliance, and reflective surface performance that cuts cooling loads during those 110°F August stretches. We install standing seam and concealed-fastener systems from Tamko and GAF, properly flashed for the wind-driven rain that comes with mountain-pass Santa Anas.
Metal’s not cheap. In Pomona, a full metal replacement typically starts around $22,000 and can reach $40,000+ for complex hillside architecture. But for homeowners who intend to stay - and our typical Pomona customer has been in their house twenty-plus years - it’s a once-and-done solution that outlasts three shingle cycles.

Full Roof Replacement
When the decking’s compromised, the underlayment’s failed, or you’re looking at a second layer that needs stripping, we handle complete tear-off and replacement. In Pomona, this means accounting for heavier tile loads on historic homes, low-slope transitions on Phillips Ranch additions, and the fire-code overlays that foothills properties require. Our Roof Replacement & Installation team manages permits, inspections, and haul-off - you don’t coordinate subs, and you don’t chase paperwork.

New Construction
Building new in Pomona’s northern reaches? We spec from the truss up, with sheathing, underlayment, and finish materials selected for your specific zone - standard wind exposure for valley floor, enhanced fastening patterns and Class A assembly for foothills fire zones. We work directly with your builder or architect, and we document every phase for the final inspection.

Flat Roofing
Low-slope garage or addition sections on 1970s-80s tract homes in Phillips Ranch use aged single-ply or built-up membranes that reach end-of-life unnoticed, causing hidden interior water damage. We replace with modern TPO or modified bitumen systems, properly tapered for drainage and sealed at all penetrations. Pomona’s thermal expansion demands detail work that cheaper crews skip.

For foothills tile jobs, we keep Boral’s Class A concrete tile and matching trim in regional supply, so your color match doesn’t wait on a freight line from Texas.

We don’t substitute without your written approval, and we don’t promise what we can’t source.
Common Roof Replacement & Installation Problems We See in Pomona Homes
- Heat-blistered shingles failing in 5-7 years instead of 15-20. Pomona’s sustained 105-110°F summer temperatures cook standard asphalt. We see this most on south- and west-facing slopes in Phillips Ranch and central Pomona, where attic ventilation was never upgraded from 1970s standards.
- Original clay tiles cracked from decades of thermal cycling, with Santa Ana wind uplift finishing the job. The mountain passes north of Pomona accelerate fall and winter wind events. Improperly fastened tiles lift, break, and create cascade failures across the slope.
- Hidden low-slope membrane failure on garage additions and patio covers. Single-ply and built-up roofs from the ’80s reach end-of-life quietly. Water migrates to walls and soffits before you see a ceiling stain. We find this constantly in south Pomona tract neighborhoods.
- Fire-code surprises mid-project in foothills zones. Homeowners expecting a like-for-like shingle re-roof discover their property falls within LA County’s High Fire Hazard Severity Zone, requiring Class A assembly. We catch this in initial inspection, not at permit counter.

FAQs - Roof Replacement & Installation in Pomona
If your property is in Pomona’s northern foothills within LA County’s High Fire Hazard Severity Zone, yes - Class A fire-rated roofing is mandatory on all permitted re-roofs. Valley-floor neighborhoods in south Pomona and Phillips Ranch generally fall outside these zones and can use standard Class C materials, though many homeowners still upgrade for insurance benefits and resale value. We verify your specific parcel’s zone designation during our free inspection and spec materials accordingly. Call (877) 367-1429 and we’ll check it before you commit to anything.
Pomona’s inland valley location subjects roofs to sustained summer heat of 105-110°F, which accelerates the asphalt oxidation and fiberglass mat degradation that causes blistering, curling, and granule loss. Standard 3-tab shingles rated for 20-25 years in moderate climates often fail in 10-12 years here, especially on south-facing slopes with poor attic ventilation. We specify architectural shingles with enhanced UV stabilizers and design ventilation systems for Pomona’s thermal load, which typically extends service life to 18-22 years. For a specific assessment of your roof’s condition, call (877) 367-1429 - estimates are free.
You can, but you may not want to - and in foothills fire zones, you may not be allowed to. Shingle roofs are lighter and cheaper upfront, but they don’t meet Class A fire requirements for High Fire Hazard Severity Zone properties, and their lifespan in Pomona’s heat is roughly half that of concrete tile. We also find that stucco homes in Lincoln Park Historic District and similar neighborhoods lose significant aesthetic value with shingle substitution. If you’re considering a material change, we’ll walk the actual trade-offs for your specific property and zone. Call (877) 367-1429 to schedule a consultation.
Many Pomona homes built before 1960, including the Craftsman bungalows and Spanish Revival properties in central and north Pomona, were framed for lighter clay tile or even wood shingle loads. Modern concrete tile from Boral or equivalent can weigh 900-1,200 pounds per square - significantly more than original materials. We always verify rafter spacing, span, and existing load capacity before quoting tile replacement. If reinforcement is needed, we engineer it to current LA County standards and include it as a line item in your upfront estimate, not a mid-project surprise. Call (877) 367-1429 for structural evaluation.
Santa Ana winds funneled through the San Gabriel Mountain passes directly north of Pomona create sustained high-velocity events every fall and winter, with localized gusts that test every fastener on your roof. We specify enhanced fastening patterns for all Pomona installations - six nails per shingle in wind zones, heavy-duty tile clips and screws instead of old-style wire ties, and reinforced perimeter fastening on low-slope membranes. Our tile work includes upgraded underlayment and proper headlap to prevent wind-driven rain intrusion. This isn’t coastal LA. We install for the mountain winds that actually hit your roof. For wind-rated installation specifics on your property, call (877) 367-1429.
