The Fan on the Curb, and the Roof Under It
The rooftop fan is the piece most often skipped and the one carrying the most grease. An upblast fan sits on a curb over the duct riser and belongs on a hinge so it tilts clear of the opening. Once it is up, the wheel, the underside of the housing, and the top of the riser are reachable, and those are the surfaces condensed grease has been draining onto all along. The fan also needs a drain running into a containment cup rather than onto the roof, because grease on a membrane softens it and holds standing water, which turns a housekeeping item into a roofing repair.
On a low-slope roof in the region that matters more than it sounds, because wet-season rain arrives fast and heavy, and the softened patch is exactly where it stops draining. Reassembly counts too: a fan set back out of line, or a belt left slack, moves less air, and less air means a heavier deposit next cycle.
Air balance is worth a thought while someone is up there. A hood removes a large volume, and a makeup air unit is supposed to return it. When it does not, the kitchen sits negative and pulls replacement air down whatever opening it can find. If that opening is a flue, over a wood-fired oven or a dining room fireplace, its draft reverses whenever the hood runs. That is a hood balance problem disguised as a chimney complaint.
How Often Depends on What You Cook
Frequency is not annual by default. The schedule follows cooking volume and fuel. Solid fuel, a wood-fired oven or a charcoal grill, sits at the short end at monthly, and has to exhaust through its own dedicated system rather than share with the gas appliances. High-volume cooking, meaning round-the-clock service, charbroiling, or wok work, runs quarterly. Moderate volume, where most sit-down restaurants land, is twice a year. Low volume, a seasonal kitchen, a church hall, a camp dining room, is annual. Two kitchens on the same block with identical hoods can be a year apart, and what decides it is the menu.
Which of These Duct Services You Need
Three services here clean something people call a duct, and the fuel sorts them out. If your run begins over a cooking line and a motor pulls it, the deposit is grease and this is the page. If it begins over a fire lit for heat or for atmosphere, a lobby fireplace or a dining room hearth, the deposit is creosote and the flue works on temperature difference rather than a fan, which puts you on commercial chimney cleaning. If it begins behind a dryer, the deposit is lint. No interval transfers between them.
Length, existing openings, and roof access move the size of a grease duct job, so the free estimate visit follows the walk-through.

How commercial grease duct cleaning pricing works in your area
Commercial Grease Duct Cleaning does not have one fixed sitewide price. These are the property-specific factors that can change an estimate:
- the appliance, fuel, flue configuration, and requested service
- chimney height, roof pitch, access, and conditions at the property
- the amount and condition of residue or debris found during the assessment
- whether an obstruction, animal activity, or damaged component changes the proposed scope
- any additional service that is separately described and approved in writing
A technician can look at the chimney or fireplace and give you a free estimate for the requested service.

Commercial Grease Duct Cleaning for your area's varied housing stock
Masonry chimneys, framed chases, and factory-built systems do not share one cleaning scope. The appropriate commercial grease duct cleaning scope depends on the actual appliance, flue, access, and condition rather than the home's age alone.
Choosing a commercial grease duct cleaning contractor
When comparing commercial grease duct cleaning companies or contractors, ask what the estimate visit includes, what condition the recommendation addresses, and what happens before paid work is scheduled.
