Grandmark Service Company — Fresno Roofing
(559) 272-7495 · CSLB #1030917
The roofers Fresno homeowners call back
Grandmark Service Company (CSLB #1030917) is a family-owned roofing company built on in-house crews — our own roofers, never subcontractors. We work on tile, shingle, flat and metal roofs across Fresno County, remove and reinstall solar panels for reroofing projects, and document every inspection and repair on video. Roofing in Fresno has a trust problem, and it’s earned: too many homeowners have paid for work they could never verify. That’s the whole reason we record it.

The Valley heat doesn’t ask permission
Fresno summers push roof surface temperatures well past 160°F for months at a time. Combined with older clay tile stock and dust-storm debris, that’s the pattern our roofers see on repair calls across the 93701–93730 zips. Most roofs here don’t fail from one dramatic event — they fail slowly, from the same three stresses repeating every summer until something finally gives.
UV & heat cycling
Repeated expansion and contraction cracks shingle seals and clay tile years before a coastal climate would show the same wear. A roof rated for 25 years often shows granule loss and seal failure in Fresno by year 15–18.
Attic & duct heat load
A failing roof deck and leaking ducts compound each other — your AC works harder while the energy bill climbs. See attic ventilation →
Dust storm debris
Valley wind events drive debris into flashing and gutters, the most common cause of small leaks that become big ones. See gutters & gutter guards →

Why this saves you money →Full-scope roofing in Fresno
Beyond repair and replacement — the material-specific and supporting work Fresno homes and commercial buildings actually need.
Four steps. Documented at every one.
Free inspection
A licensed estimator walks your roof and records the pre-job video with you, pointing out exactly what’s failing and why.
Written scope
One clear estimate, financing shown up front, and a specific timeline instead of a vague “few days.”
Job, documented
Our roofers record every penetration and seal before it’s covered, so nothing about the finished roof is a mystery.
Post video handoff
You get the completion video the same day. No proof, no invoice — that rule doesn’t bend for scope size.
What a Fresno roof actually costs
We publish ranges instead of making you call for a number. See the Fresno roof replacement cost guide → for a breakdown by material and roof size, or Fresno roofing financing → for terms.
Down, every project
No money down on approved roofing work, with same-day approval and no early payoff penalty.
Insurance claims
Storm or hail damage is often a covered claim. We document the damage on video the same visit. See claims help →

What the video proof actually feels like
Most of our new calls come from a neighbor or a past customer who showed someone their completion video. Read Fresno roofing reviews → or see reviews from every Grandmark location →
Two other Fresno roofers wanted to sell a full replacement. Grandmark’s video showed the real problem was a repair — saved thousands.
They replaced our tile roof and the ducts at the same time — didn’t know that was even possible. Video proof of every step.
Storm hit on a Friday. Crew was there same day and documented everything on video for the insurance claim.
Fresno roofing FAQ
More detail on the full Fresno roofing FAQ →
How do I choose a roofer in Fresno?
Check the CSLB license number against the state database, confirm the crew is in-house rather than subcontracted, and ask what documentation you get when the job is finished. Any roofer can promise quality work; far fewer will hand you video of every penetration and seal before it was covered. Ours is #1030917 and you can verify it in about thirty seconds.
How fast can you get to a leak?
Same-day service is available in most Fresno-area zip codes. Call and we’ll confirm a window before we hang up — during a storm we prioritize by severity, not by order of the call.
What does “video proof” actually cover?
A pre-job walkthrough showing the existing condition, and a post-job video showing every completed penetration, seal, and repair before we invoice. You keep both — useful if you sell the home or file a warranty claim later.
Do you really replace ducts during a re-roof?
Yes. With the deck open it’s the cleanest time to reach ductwork — no ceiling cuts, no contamination inside the home, and typically less than doing the two jobs separately. See roof + duct combo.
How long does a full roof replacement take?
Most single-family Fresno homes are a one-to-two day job once materials are on site, weather permitting. Tile and multi-story homes run longer — your estimator gives you a real timeline during the inspection, not a generic range.
Are you licensed and insured in Fresno?
Yes — CSLB #1030917, fully licensed and insured, GAF Master Elite certified and BBB A+ rated.
