Why roofing and HVAC jobs usually fail to fix anything
The deck is wide open. The ducts are right there. But your roofer isn’t an HVAC tech, so they do nothing — you get a new Fresno roof with a contaminated, leaking duct system underneath it. Or the AC gets replaced, but the roof penetrations get patched by someone who doesn’t roof for a living. Six months later: water damage, callbacks, and nobody taking responsibility.
A roofer who won’t touch ducts
Your deck is open — the easiest access point your ductwork will ever have. A roofing-only crew has no reason to look, so a leaking, contaminated duct system goes right back under the new roof, untouched.
An AC tech who doesn’t roof
New system installed, but the roof penetrations get sealed with caulk by someone who installs equipment for a living, not roofs. It looks fine until the next storm season proves otherwise.
Two invoices, zero accountability
When something fails at the seam between the two systems, each contractor blames the other. Neither documented the handoff, so neither owns the callback.
Full diagnostic. One clear scope. Nothing left to guesswork.
Full diagnostic
Roof, attic, ductwork, and HVAC system inspected together, on video, before any scope is written.
HVAC work through the open deck
Duct replacement or repair completed through the same access point your roof crew already opened — no ceiling cuts, no second mobilization.
Roofer-sealed penetrations
Every duct and vent penetration sealed by a licensed roofer — not caulked by whoever installed the HVAC equipment.
Every job documented from first inspection to final seal — roof, ducts, penetrations, all on camera, all yours to keep. Pre and post video report included, no exceptions.
One mobilization instead of two
Hiring a Fresno roofer and an HVAC company separately means two estimates, two crews, two mobilization fees, and two separate cleanup passes — often for work that could have happened in a single visit. Combining the job through the same open access point is typically less expensive than doing both separately, and it removes the coordination risk entirely.

They replaced our roof and the ducts at the same time — didn’t know that was even possible. House is cooler than it’s been in years and I have video proof of every step.
Grandmark did an amazing job fixing our roof and duct work together — recommend them 10/10. Thank you for making our home look great.
Our house is finally comfortable in the summer. They did the roof and the ducts at the same time — best decision we’ve made as homeowners.

Roof + Duct Combo FAQ — Fresno
Is the combo job actually cheaper than hiring separately?
In most cases, yes. You avoid a second mobilization fee, a second cleanup pass, and the scheduling gap between two separate companies. The exact savings depend on your specific scope.
Do I need both a new roof and new ductwork to qualify?
No. We combine the jobs when it makes sense — if your roof and duct condition both point the same direction during inspection. If only one system genuinely needs work, we tell you that honestly.
Who actually seals the roof penetrations — the roofer or the HVAC tech?
A licensed roofer, always. Every penetration on every job we do is sealed by someone who roofs for a living, not caulked by an HVAC technician on the way out.
Do you offer financing for combo jobs in Fresno?
Yes — combined roof-and-duct jobs qualify for financing the same way either trade does on its own, with $0 down and same-day approval in most cases. See our Fresno HVAC financing options →.
