Roofing and HVAC services, all backed by the same standard
Whatever brought you here — a leak, a dead AC unit, or a full remodel — every service below starts with a free inspection and ends with a video showing exactly what we did. We’d rather you know exactly what you’re paying for than trust a stranger’s word on it. Browse by trade below, or call and describe the problem and we’ll point you to the right one ourselves.
Every roof service, one standard
From a single active leak to a full tear-off replacement, our roofing crews are GAF Master Elite certified and document every job with pre and post video. Available in Fresno, Visalia, Sacramento, and Bakersfield. Most homeowners call us for one of three reasons: an active leak that needs a same-day answer, a roof that’s clearly past its useful life and needs replacing before it fails outright, or a pre-sale inspection where a clean roof report matters as much as the roof itself.
Roof Repair
Leak diagnosis, flashing repair, and shingle or tile patching. Same-day service available in most areas.
See roofing hub →Full Replacement
Complete tear-off, deck inspection, and GAF Master Elite shingle or tile install with manufacturer warranty.
See roofing hub →Metal, Flat & Tile
Specialty roof systems for commercial buildings and older Central Valley homes, repaired and installed to code.
See roofing hub →Emergency Repair
Active leak during a storm? We prioritize by severity, not by order of the call.

Our HVAC crews use a video diagnostic process before quoting any repair, so you know exactly what’s failing before you spend a dollar. Available across all 5 California markets. The most common calls we get are a system that’s no longer cooling effectively during Valley summers, a furnace that fails right before the first cold snap, and homeowners who suspect — correctly, more often than not — that their ductwork is leaking conditioned air into an attic instead of into their rooms.
AC Repair & Installation
Diagnostics, repair, and full system replacement for residential and light commercial properties.
See HVAC hub →Furnace Service
Repair and installation ahead of Central Valley winters, when a failed furnace can’t wait.
See HVAC hub →Duct Replacement
Sealed, contaminant-free duct replacement — on its own, or paired with a roof job through the same access point.
See HVAC hub →Roof + Duct Combo
Our signature cross-trade service. One crew, one invoice, typically less expensive than hiring two separate companies.

Why roofing and HVAC often get done together
If your roof deck needs to come off anyway, that’s also the easiest and least invasive time to access and replace failing ductwork — no ceiling cuts, no drywall repair, no separate mobilization for a second crew. We see this most often on homes over 20 years old, where both systems tend to be reaching end-of-life around the same time, often for related reasons — a failing roof deck and leaking ductwork tend to compound each other rather than fail independently. It’s not a package we push on every job; it’s simply the option we walk you through if your roof and duct condition both point the same direction during inspection.
Every service above follows the same four steps
Free inspection
A licensed estimator documents the existing condition with you, on video, before any work is quoted.
Written scope
One clear estimate covering roofing, HVAC, or both — no hidden line items, financing shown up front.
Job, documented
Every repair or install is recorded before it’s covered up or closed in.
Post video handoff
You get the completion video the same day the work finishes. No proof, no invoice.
This isn’t a special process reserved for larger jobs — a single shingle repair gets the same four steps as a full replacement or an AC install. Read the full explanation on The Grandmark Standard →
Questions we get about our services
Do I have to choose between repair and replacement myself?
No — that’s what the free inspection is for. Our estimator will tell you honestly which one makes sense for your situation, including cases where a repair now genuinely buys you several more years before replacement is worth it.
Is HVAC available everywhere Grandmark works?
HVAC service is currently available in Fresno and Visalia. Sacramento and Bakersfield offer roofing (and AC in Bakersfield’s case) — check our service area page for the current list by city.
How fast can someone come out?
Same-day service is available in most areas for active leaks or a fully non-functional AC or furnace. Non-urgent inspections are typically scheduled within a few days.
Is the free inspection actually free, no strings attached?
Yes. You get a written scope and price whether or not you move forward with the work.
What if I only need one trade, not both?
That’s most of our calls. There’s no pressure to bundle roofing and HVAC — we quote exactly the scope you need, and only mention the combo option if your roof and duct condition both genuinely point that direction during inspection.
Financing available for both trades
Roofing and HVAC projects — including combined roof-and-duct jobs — qualify for financing, discussed during your free inspection so you know your options before committing to a scope. We’d rather walk you through real numbers up front than have cost be the reason you delay a repair that’s only going to get more expensive the longer it waits. See financing details →
Not sure which service you need?
