If your roof is leaking, has missing tiles after a wind event, or you’re seeing daylight through the decking, we can usually get an estimator to your Fontana home same-day or next-day. Call (877) 367-1429 - a live person answers, even at 10 PM on a Sunday.
We’ve been climbing Fontana roofs since 1984. We know the Kaiser Steel tract homes south of the 10 Freeway with their original low-slope sections, the north Fontana master-planned communities where 1990s tile roofs are hiding powder underlayment, and the way the Cajon Pass funnels Santa Ana winds straight down Sierra Avenue. That local knowledge changes what we look for during inspection, what materials we recommend, and how we detail the edges so your roof holds when the next Diablo event hits.
Why Ridgeline Roofing Co. of California Is Fontana’s Preferred Roof Replacement & Installation Company
We’re not storm chasers with out-of-state plates and a rented mailbox. Ridgeline Roofing Co. has been rooted in Southern California for over 42 years, and our crews include journeymen who live in the Inland Empire, shop at the same Fontana hardware suppliers, and understand that a roof here faces different tests than one in Orange County or the Valley.
Our reputation in Fontana is built on showing up when we say, documenting what we find with photos from your actual roof, and standing behind the work with our written 90-Day Done Right Promise. No paperwork to file, no runaround - if it’s not right, we come back and make it right.
When you call (877) 367-1429, a live person answers. Not a voicemail tree, not a callback promise that evaporates. We’ve had Fontana homeowners tell us they called three other contractors before us, left messages, and never heard back. We think that’s no way to treat someone whose ceiling is staining.
Our technicians are background-checked, uniformed, and trained to inspect for the specific failure patterns we see in Fontana: wind-lifted shingles from Cajon Pass funneled gusts, thermal-cycling fatigue on south-facing slopes, and that deceptive north Fontana tile scenario where everything looks fine until it doesn’t.
Our Roof Replacement & Installation Services in Fontana
Full Roof Replacement
Most Fontana homeowners who call us for Roof Replacement & Installation are dealing with roofs that have reached the end of honest service life. In south Fontana’s 92335 ZIP code, we regularly strip off multiple layers of built-up roofing from 1960s Kaiser-era homes, finding deck rot where trapped moisture has been eating plywood for years. In the 92336 subdivisions north of Summit Avenue, we’re replacing tile roofs where the concrete S-tiles still look presentable but the original 15-lb felt underneath has turned to dust. We handle complete tear-off, deck repair, proper ventilation upgrades, and installation of your chosen material - with permits pulled and inspections scheduled so you don’t have to chase the city.
Tile Roofing
Concrete and clay tile is the standard across north Fontana’s 1990s-2000s developments, and when installed correctly with modern underlayment, it handles our heat and UV better than almost anything. The problem we encounter is original underlayment failure. That 15-lb felt installed in 1995 was never meant to bake under Fontana’s 105°F summer peaks for thirty years. We’ve opened tile roofs in the Heritage Village area where the felt crumbled like chalk - the tiles were fine, the protection underneath was gone. We install Boral and Eagle-compatible systems with upgraded synthetic underlayment, proper bird stops, and wind-resistant fastening that meets the standards Fontana’s location demands.
Asphalt Shingles
For Fontana homeowners replacing a shingle roof, we specify architectural-grade products with the highest wind ratings available, because standard three-tab shingles don’t survive our Santa Ana events. GAF Timberline HDZ and CertainTeed Landmark PRO both carry 130-mph wind warranties when installed to manufacturer spec, and we nail to that spec, not to the minimum. The daily thermal cycling here - 105°F afternoons dropping to 60°F nights during shoulder seasons - accelerates granule loss and seal-tab fatigue. We see this especially on south and west exposures in the Sierra Lakes area. We factor exposure into our material recommendation and ventilation design.
Flat and Low-Slope Roofing
Fontana’s older housing stock includes more flat and low-slope sections than many Inland Empire cities realize. Those 1950s-1970s Kaiser tract homes on Merrill Avenue and south of Foothill Boulevard often have rear additions or carport roofs with minimal pitch that were originally done in hot-mop built-up roofing. After sixty years, that tar and gravel is a liability. We install GAF Liberty SBS-modified bitumen systems, TPO, or PVC depending on the application, always with proper insulation and drainage detail. In the 92335 ZIP code, we replaced a 1960s low-slope built-up roof on a Kaiser tract home where multiple layers of old tar and gravel had trapped moisture, causing deck rot. We stripped it to the deck, installed GAF Liberty SBS-modified bitumen, and added a wind-resistant drip edge per Fontana’s high-wind standards.
New Construction Roofing
If you’re building in Fontana’s newer developments or adding an ADU, we coordinate with your framer and general contractor to spec the right system from the start. Fontana’s combination of extreme UV, thermal cycling, and wind exposure means the cheapest specification is never the most economical over a twenty-year horizon. We install to manufacturer requirements with no corners cut, because we intend to be here when that roof needs its first honest inspection.
Metal Roofing
Standing seam and metal shingle systems are gaining traction in Fontana for their durability and reflective properties. We install Tamko’s metal shingle line and custom standing seam in galvalume or painted finishes that carry 40-year paint warranties. Metal handles our thermal cycling without the granule loss that plagues asphalt, and when detailed correctly at valleys and penetrations, it sheds the hard, wind-driven rains that come off Cajon Pass. Not every Fontana home’s structure is suited for metal’s weight or profile, so we assess honestly rather than sell what’s easy.

Trusted Brands We Service in Fontana
We’re authorized installers for seven manufacturer lines - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we stock common repair materials and color-matched accessories for Fontana customers rather than ordering everything from a distant warehouse. That means when we find a problem, we can often fix it without a two-week wait for matching shingles or tile. For Fontana’s climate, we typically lean on GAF and CertainTeed for asphalt shingle durability, Boral for concrete tile systems, and Tamko for metal applications where heat reflectance matters. We don’t substitute materials without your knowledge. The brand on your contract is the brand on your roof.
Common Roof Replacement & Installation Problems We See in Fontana Homes
- Underlayment failure in north Fontana tile roofs. The concrete tiles look intact from the street, but the original 15-lb felt installed in the 1990s has baked to powder underneath. We’ve found this in subdivisions off Summit Avenue and north of Sierra Lakes Parkway. The roof appears fine until a hard rain finds the one gap.
- Wind-lifted shingles and displaced tiles during Santa Ana events. Fontana’s position at the base of Cajon Pass creates wind acceleration that neighboring Rialto and Ontario don’t experience to the same degree. Unseated shingles lift and tear. Concrete tiles on older homes with corroded fastening systems slide or crack.
- Thermal cycling fatigue on asphalt shingles. Fontana’s 105°F summer peaks followed by rapid overnight cooling from the mountains creates more daily expansion-contraction stress than coastal or even valley markets. Granule loss accelerates, seal tabs fatigue, and the effective lifespan drops below manufacturer projections.
- Multiple-layer built-up roof failure in south Fontana’s 1950s-1970s housing. Those Kaiser-era homes near Merrill Avenue and south of Foothill often carry two or three layers of tar and gravel. The weight stresses structure, and trapped moisture between layers rots decking that could have lasted decades longer.

FAQs - Roof Replacement & Installation in Fontana
The concrete tiles are likely fine, but the original 15-lb felt underlayment installed in the 1990s has probably degraded to powder under them. This is the most common hidden failure we find in north Fontana subdivisions like Sierra Lakes and Heritage Village. The tiles shed most water, but wind-driven rain finds the gaps in disintegrated felt. We recommend a lift-and-inspect to assess underlayment condition before you have an interior leak. Call (877) 367-1429 - estimates are free, and we’ll show you photos of what we’re seeing.
Fontana sits where the San Gabriel and San Bernardino ranges funnel Santa Ana and Diablo winds directly into the city, creating measurably higher wind exposure than Rialto or Ontario to the west. Every Fontana installation we do includes wind-resistant edge detailing, proper shingle fastening patterns, and material specifications rated for the wind speeds this geography produces. We don’t install to minimum code here. We install to what the mountain gap actually delivers.
If your south Fontana home still carries original built-up roofing from the Kaiser Steel era, replacement is almost always the honest recommendation. These roofs are sixty-plus years old, often hide multiple layers that trap moisture, and the repair materials compatible with old tar-and-gravel systems are increasingly unavailable. A quality flat roof replacement with modern modified bitumen or TPO runs $9,500-$17,000 in Fontana and gives you a system designed for current wind and thermal loads. Call (877) 367-1429 and we’ll assess whether any portion is salvageable - but we’ll tell you straight if it’s time to strip it.
Concrete tile with modern synthetic underlayment handles Fontana’s 105°F peaks and intense UV better than any other residential system, which is why it’s the standard across north Fontana’s 1990s-2000s developments. For pitched roofs where tile isn’t suitable, architectural asphalt shingles from GAF or CertainTeed with cool-roof granule technology perform well when paired with proper ventilation. Metal roofing in lighter reflective colors is increasingly popular for its durability and heat reflectance. We match the material to your structure, exposure, and budget - no generic recommendations.
Look for cracked or sliding tiles, visible underlayment where tiles have shifted, and any interior ceiling stains after previous rains. But the critical warning sign you can’t see from the ground: original felt underlayment that has turned to powder. We find this routinely in north Fontana’s 92336 ZIP code. If your tile roof is 25-30 years old and has never had underlayment replacement, schedule an inspection before the next Santa Ana event. Call (877) 367-1429 - we’ll lift a few tiles, photograph the underlayment condition, and give you a straight answer on timeline.
