Roofing and HVAC, from the same company
Most homeowners end up hiring a roofer and an HVAC company separately, coordinating two crews, two estimates, and two timelines. Grandmark Service Company runs both trades under one roof — literally, since roof and duct work often happen on the same job — so you get one point of contact, one video-proof standard, and one company standing behind both. That matters most when something breaks in both systems at once, which happens more often than people expect: a failing roof deck and leaking ductwork tend to show up together, not separately, especially in older Central Valley homes.
Roofing
Repair, full replacement, and specialty roof systems across Fresno, Visalia, Sacramento, and Bakersfield. GAF Master Elite certified.
HVAC
AC and furnace repair, replacement, and duct work in Fresno and Visalia, backed by our X-Ray diagnostic process.
Roof + Duct Combo
Replace ductwork through the same access point as a re-roof — sealed, contaminant-free, no ceiling cuts, and typically less expensive than doing both separately.
What 28 years actually buys you
Longevity alone doesn’t mean much — plenty of companies stick around by cutting corners, changing names, or getting bought out and rebranded until the original reputation is unrecognizable. We’re still run by the same people, answering the same number, holding ourselves to the same standard we started with. Here’s what ours actually translates to for a homeowner deciding who to call.
A number you can call back
Same company, same phone number, same crew standard whether it’s your first call or your fifth job with us over a decade.
Proof instead of a promise
You don’t have to trust that the work was done right — you have the video showing it was, before it ever got covered up.
One company, both trades
No finger-pointing between a roofer and an HVAC company when a problem touches both systems — we own the whole job.

Two other Fresno roofers wanted to sell a full replacement. Our video showed the real problem was a repair — saved thousands.
AC went out at 9pm, 104 degrees outside. Crew was out by 8am, diagnosed on video, fixed same visit.

Common questions before you call
Do you actually do both roofing and HVAC, or is one a referral?
Both are done in-house by our own licensed crews — we don’t subcontract either trade out. Availability varies slightly by location; Sacramento and Bakersfield are roofing-only today, while Fresno and Visalia run both trades.
What does the free inspection actually involve?
A licensed estimator walks the property, records a pre-job video with you narrating what they find, and gives you a written scope and price before any work is scheduled — no pressure to decide on the spot.
Do you offer financing?
Yes, for both roofing and HVAC projects, including combined roof-and-duct jobs. Options are discussed during your free inspection so you know what qualifies before you commit.
How do I know which location serves my address?
Check our full service area list, or just call — we’ll tell you immediately whether we cover your address and which crew handles it.
What makes the video-proof standard different from a normal warranty?
A warranty tells you what’s covered if something goes wrong later. The pre/post video shows you exactly what was done the day of the job — the condition before, the actual repair, and the finished result — so you’re not relying on paperwork alone if a question ever comes up.
