Free roof inspection with deck photos before we talk money - GAF and Owens Corning certified installation
Fast, Reliable Roofing Company Across Fresno
If your Fresno roof is leaking, shedding granules into the gutter, or simply past its useful life, a full replacement on a typical 1,800-square-foot ranch runs $9,500 – $15,500 depending on pitch, decking condition, and shingle grade. A targeted repair usually lands between $450 and $1,900. That’s the honest range, and we put it in writing before a single nail comes out of the box. Mercer Roofing serves the entire Fresno metro, from the 1950s tract homes west of Highway 99 to the 1990s tile-roof subdivisions along the Shaw and Herndon corridors. We’re here because Fresno roofs fail differently than roofs anywhere else in California. Call (743) 200-8347 and we’ll send a background-checked, photo-badged technician whose name you’ll know before he rings the bell.
Why Mercer Roofing Is Fresno’s Preferred Roofing Company
Fresno homeowners call us because we treat the stranger-at-the-door problem as seriously as the roof problem. Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. You get the technician’s name and photo before the visit. When he arrives, he’s in a clean, marked uniform with a photo ID badge. You know exactly who is stepping onto your property. That matters more here than people admit until they’ve had a bad experience.
We’re part of the Threshold Group family of home-service companies, founded in 2000. Each location is independently owned and operated, held to the Threshold Verified standard on every visit. Our crews know the specific failure patterns of Fresno’s housing stock because they see them weekly. Granule loss on south-facing slopes in Sunnyside. Flashing failures where Tule fog sits for weeks in the Tower District. Rotted decking under tile on 1990s tract homes out past Fig Garden. This is not generic roofing knowledge. It’s what you learn when you actually work here.
Every repair we make in Fresno carries a written 365-Day Done Right Promise. If it’s not right within a year, we make it right. Every repair comes with a free second visit if it fails. And a live person answers our phone 24/7. Not a voicemail. Not a call-back form. A human being, any hour you call.
Free Roof Estimate in Fresno
Free Roof Estimate: a Mercer technician walks your entire Fresno roof, photographs every problem area, and hands you a written line-item price before any work begins. No estimate means more work because we charge by what we find, not by what we guess. On a Fresno ranch home, expect about an hour on site and a written quote in hand the same day.
What the walkthrough covers
We inspect shingles or tile, flashing at chimneys and valleys, drip edge, gutters, pipe boots, and attic ventilation. On homes in the Shaw-to-Herndon corridor, we specifically check hip caps and underlayment because that’s where 1990s tile roofs hide their rot. The estimate is free. The information is yours either way.
What happens after
You’ll get a written price with materials, labor, and any decking replacement specified separately. No change orders later unless you decide to add scope. If two roofs in Fresno look identical from the street but one needs $2,400 in decking work, you’ll know that before we start, not after we tear off.
Roofing Contractor in Fresno
Roofing Contractor: when you need a full roof replacement or a major structural repair in Fresno, you need a contractor who works in Climate Zone 13 every day, not someone driving in from the coast who’s never dealt with Title 24 cool-roof compliance. Mercer Roofing handles permit-pulled, inspection-passed re-roofs throughout Fresno, with written pricing and no surprises on the invoice.
Full replacements and structural work
A full tear-off and replacement on a Fresno home typically runs $8,000 – $14,500 for asphalt shingle systems. Concrete tile re-roofs start around $14,000 and can exceed $22,000 once hidden decking and underlayment are addressed. We specify materials that meet Fresno’s specific thermal and moisture demands, not whatever is cheapest at the supplier that week.
Materials we specify
We install GAF, CertainTeed, Owens Corning, and IKO shingle lines, and we match cool-roof-compliant colors for Title 24. For underlayment, we spec synthetic products on re-roofs where old felt has failed. Fresno’s heat bakes cheap felt into dust. The right material choice is a compliance decision, not an aesthetic preference.
Trusted Brands We Service in Fresno
We install and repair GAF, CertainTeed, and Owens Corning shingle systems across Fresno, and we keep common flashings, underlayment, and accessory parts stocked locally so we don’t wait on a distributor in Sacramento or the Bay Area when your roof needs a repair. Manufacturer-recognized installation means warranties stay intact. We also service existing IKO, Atlas, Tamko, and Boral roofs. If you’re not sure what’s on your roof, the free estimate walkthrough settles it.
Common Roofing Problems We See in Fresno Homes
- Desiccated underlayment under 1990s tile roofs. Nearly every tile roof built in northwest Fresno between 1990 and 2005 was set over single-layer 30-lb felt. That felt is now dust. The tile looks fine from the street, but moisture gets through to rotted OSB decking beneath.
- Failed hip caps on tile roofs. Thermal expansion cycles crack the mortar and fasteners at the hips first. Once a hip cap lifts, water follows. By the time you see a stain on the ceiling, the decking under that hip is usually gone.
- Granule loss and adhesive failure on south-facing slopes. A Fresno summer delivers 100+ consecutive hours above 100°F. Asphalt shingles on south and west exposures bake first. Granules shed into gutters, adhesive strips release, and the shingle loses its waterproofing years before the warranty suggests it should.
- Tule fog moisture intrusion. Eight dry months hide small flashing gaps and cracked tile. Then the Valley floor fog settles in for weeks and holds moisture against every seam. Flashing that survived summer fails in December. We see this pattern every year across central Fresno, from the Tower District to Roosevelt.
Pricing for Roofing Company in Fresno, CA
A typical asphalt shingle replacement in Fresno runs $9,500 – $15,500. Tile re-roofs run higher, commonly $14,000 – $22,000, because tile work almost always includes hidden decking replacement, felt tear-off, and Title 24 compliance on the reflectivity of the tile itself. Repairs in Fresno range from $450 for a small flashing fix to $1,900 for valley rebuilds or decking patches. What changes the final number: roof pitch, accessibility, whether the decking under your existing roof is solid, and the shingle or tile product you choose. We give you a written price before work starts, every time. No exceptions. Call (743) 200-8347 for a free estimate with real numbers.

FAQs About Roofing Company in Fresno
Yes, almost certainly. Fresno sits squarely in California’s CEC Climate Zone 13, which means re-roofing projects must meet Title 24 cool-roof requirements for solar reflectance and thermal emittance unless the roof qualifies for a specific exemption. This affects shingle color and, for tile or metal, the specific product you choose. We handle the compliance paperwork and spec materials that pass on the first inspection. Call (743) 200-8347 and we’ll check your specific roof against current code before you spend a dollar.
Because the failure is in the underlayment, not the tile. Builders in the 1990s Shaw-to-Herndon corridor set concrete tile over a single layer of 30-lb felt, which desiccates into dust after 25 years of Fresno heat. The tile looks fine from the street. Water passes through the dried felt, rots the OSB decking at the hips and valleys, and your roof is failing invisibly. A free estimate walkthrough from Mercer Roofing includes an on-roof inspection, not a driveway glance. Call (743) 200-8347 to schedule one.
Fresno’s sustained 105°F-plus summer weeks bake standard galvanized flashing, thin-mil underlayment, and low-grade adhesive strips far faster than coastal conditions do. We specify synthetic underlayment with higher temperature ratings, heavier gauge flashing at valleys and penetrations, and shingle products tested for high-heat granule retention. The material upcharge is usually 8 – 15% over a budget spec. Not spending it means you’re paying again in a decade.
Tule fog holds moisture against roof surfaces for weeks at a time. Any cracked tile, open flashing seam, or loose pipe boot that stayed dry all summer becomes a water path in December and January. The decking rots from the inside. That’s why we check flashing and tile adhesion as part of every free estimate in Fresno, not just the shingle count. Call (743) 200-8347 if you haven’t had an on-roof inspection in over a year.
Put them side by side on four lines: underlayment type, decking replacement scope, flashing spec, and cool-roof compliance. If one Fresno bid is $3,000 cheaper and doesn’t mention decking on a 1990s tile roof, it’s not cheaper. It’s an incomplete estimate that becomes a change order the day we find the rot. Every Mercer Roofing bid specifies all four lines in writing before work starts. That’s a big part of why our Roofing Company team writes every Fresno estimate line by line.
