Fast, Reliable Roof Replacement Across Fontana
A full roof replacement in Fontana typically costs between $11,000 and $22,000 for a standard asphalt shingle roof on a 1,500 – 2,200 square foot home, with architectural shingles running $4.75 – $7.25 per square foot installed. Flat roof replacement in Fontana runs $9 – $14 per square foot depending on the system. That’s the honest range before we walk your roof, because the wind corridor off the Cajon Pass changes what your roof actually needs.
Bedrock Roof Repair works throughout Fontana: from the 1970s tract homes north of Summit Avenue to the newer developments pushing toward Etiwanda and the warehouse-adjacent neighborhoods off the 10. We’re based in Anaheim, but we’re in Fontana weekly. Alan Cofield runs our crews, and he’s walked enough Fontana roofs to know exactly what the Santa Anas do to a west-facing slope. Call (833) 589-7850 and we’ll set up a free inspection.
Why Bedrock Roof Repair Is Fontana’s Preferred Roof Replacement Company
Our repair-first name tells you how we operate. When a Fontana homeowner calls about replacing a roof, we start with an inspection and tell you what the roof actually needs – repair, replacement, or nothing yet. That sequence matters here because the wind damage we see in Fontana often looks worse than it is: creased shingle tabs on one slope don’t always mean the whole roof is done. But when replacement is the right call, we say so plainly and we stand behind the work.
Our team works with seven roofing material brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means the recommendation you get is calibrated to your roof and your budget, not to whichever supplier we happen to favor. We don’t have a single-supplier relationship pushing us toward one product line. For a Fontana roof that takes Cajon Pass wind, that brand-agnostic position matters, because we can specify the exact shingle and fastener combination the job requires. One honest recommendation, backed by access to every major line.
Reputation is earned through specifics. We’ve rebuilt roofs in Fontana neighborhoods from Southridge to West End to the Etiwanda foothill tracts. Same team from inspection to final nail – no handoffs, no surprises.

Flat Roof Replacement in Fontana
Flat roof replacement in Fontana addresses a different set of problems than shingle work. Many 1960s and 1970s homes in south Fontana and some commercial buildings along Valley Boulevard have built-up or modified bitumen roofs that were never designed for 100°F inland summers and the thermal cycling that comes with them. We see membrane splits, failed lap seams, and drainage issues that let ponding water sit after the winter storms roll through.
What the Job Involves
We tear off the old membrane, expose the decking, and check for dry rot around penetrations and drains. Then we install a new system: single-ply TPO or PVC, or a two-ply modified bitumen assembly, depending on the roof’s use and the building’s insulation strategy. Flat roof replacement in Fontana runs $9 – $14 per square foot installed, including tear-off and disposal.
When a Fontana Homeowner Needs It
If your flat roof is 15 – 20 years old and you’re seeing blisters, exposed fiberglass, or recurring patches that fail, replacement costs less than repeated repairs over the next five years. Our inspection crew will measure the actual square footage, check the drainage slope, and give you a written line-item price before any work starts.
Roof Installation in Fontana
Roof installation in Fontana on new construction or a full tear-off follows the same fastening rules every time: pass-wind spec or nothing. For homes in the 92337 and 92336 zip codes, especially the foothill tracts near the Cajon Pass, we specify stainless-steel ring-shank nails and a six-nail pattern on every shingle. The extra cost is real but modest, and it’s the difference between a roof that holds through the next Santa Ana event and one that starts shedding tabs in five years.
New Construction and Additions
We install roofs on new builds and room additions from Bloomington to Etiwanda. Roof installation in Fontana for new construction runs $5 – $8 per square foot for architectural shingles, with the final number driven by roof pitch, valley count, and access.
Full Tear-Off and Re-Deck
On older Fontana homes with original mid-century shingles, we usually find decking that’s been cooked and dried out by inland heat. We replace rotted or wind-damaged sheathing with OSB, upgrade the drip edge, and install a high-temperature underlayment before the shingles go down. This is the full-lifecycle approach: the roof system gets rebuilt, not just covered over.
Trusted Brands We Service in Fontana
We install and service products from GAF, Owens Corning, and CertainTeed. For Fontana’s wind-and-sun exposure, we often recommend architectural shingles with a high wind rating, like GAF Timberline HDZ or Owens Corning Duration, paired with stainless fasteners and a reinforced ridge line. We keep stock for common Fontana roof types on hand, so when we tear off a roof and find three extra sheets of rotted decking, we don’t wait on a supplier. We’re in Fontana the same week we quote it, and we finish the job without orbiting suppliers.
Common Roof Replacement Problems We See in Fontana Homes
- Wind-creased and lifted shingle tabs on west-facing slopes. Santa Ana winds funnel through the Cajon Pass and pull at the shingles on the exposed side of the house. The damage often stays above the eave line and hides until rain reaches the decking.
- Premature granule loss from inland UV exposure. Fontana summers routinely break 100°F, and the smog doesn’t help. Asphalt shingles shed granules fast here, which exposes the fiberglass mat and shortens the roof’s life well below the manufacturer’s nominal rating.
- Rusted or under-driven fasteners. The original construction on many 1970s and 1980s Fontana tract homes used electroplated nails that corrode from decades of heat and occasional winter rain. A corroded nail loses its hold, and the first big wind event lifts the shingle.
- Debris-damaged ridge caps from the pass. Wind-driven sand, branches, and loose trash from the 15 and 10 corridors end up on Fontana roofs. Cracked ridge caps and missing hip shingles are common, and they leak slowly at the seam instead of blowing off dramatically.

FAQs About Roof Replacement in Fontana
Stainless-steel nails resist the corrosion and heat cycles that inland Fontana roofs take year after year. A galvanized nail eventually rusts at the shank, especially after decades of 100°F summers and occasional wet winters. Once a nail loses its hold, the first Santa Ana event lifts the shingle. We specify stainless ring-shank nails on every Fontana replacement because the wind corridor off the Cajon Pass exploits any weak fastener. Call (833) 589-7850 and we’ll show you what your current roof was nailed with.
Look at the west-facing slope, especially if you live near the foothill tracts in Etiwanda or north Fontana. Wind-creased shingle tabs have a permanent fold line where the tab was lifted and bent backward. You’ll also see cracked ridge caps and missing hip shingles before any water reaches the decking. These are warning signs that the roof is losing its fastening, not just its looks. If you see granule loss in your gutters after a Santa Ana event, call us. The inspection is free.
Yes. We use a high-temperature synthetic underlayment with a stronger tear rating on Fontana roofs, especially in the north foothill tracts. Standard felt can tear or peel under sustained pass winds during installation and it degrades faster in inland heat. A high-temp synthetic also resists UV degradation when the roofing is exposed during the job. The cost difference is about $150 – $400 on a typical Fontana home, and it’s not the place to save money.
A coastal-spec roof uses ordinary electroplated nails, a four-nail pattern, and standard underlayment. It works in the LA basin where rain comes steady and winds stay mild. It fails in Fontana. An inland-spec roof uses stainless fasteners, a six-nail pattern, high-temp underlayment, and a reinforced ridge line designed for pass-wind uplift. The inland-spec version costs about $800 – $1,600 more on a typical home and lasts a decade longer here. We specify the inland spec on every Fontana quote.
A square is 100 square feet of roof area. A typical 1,700-square-foot Fontana ranch has a roof between 22 and 26 squares, depending on pitch and overhangs. Bids that don’t list the square count are hiding something. When you compare quotes, divide the total price by the number of squares to get the per-square price, then check that both bids include the same fasteners, underlayment, and decking. A $300-per-square bid with standard galvanized nails will cost more within a decade than a $330-per-square bid with stainless ring-shanks. We list the square count on every written estimate.
