Rooftop Exhaust Fan Cleaning in Houston, TX
Houston Quality Hood Cleaning cleans rooftop kitchen exhaust fans for restaurants and commercial kitchens in Houston, TX. The fan is the last stop for every bit of grease your hood and duct don’t catch, and it sits on the roof where nobody checks it until something drips or squeals.
- Housing and blades degreased; belts and motor looked over
- Roof containment mats and drain covers on every job
- Most single-hood kitchens pay $150–$500 for a full-system visit
We clean the housing and blades, look over the belts and motor, and test the fan for normal speed and airflow before we leave. Containment mats and drain covers protect your roof during the job. Outside the city, we clean rooftop exhaust fans in surrounding cities as well, including Baytown, League City, Pasadena, Humble and Kingwood.

Rooftop Exhaust Fan Cleaning Services
The fan is the engine of your exhaust system. If it’s coated in grease or slipping a belt, the hood below can’t pull smoke away from the line, no matter how clean it is. Here’s what we cover on the roof, usually in the same visit as your hood and duct.
Upblast Fan Cleaning
The mushroom-shaped upblast fan is what most Houston restaurants have on the roof. It throws exhaust straight up, and grease collects on the wheel, the inside of the hood and around the base.
If needed, we tip the fan open or disconnect it to reach the blades and the inside of the housing. A wipe of the outside isn’t enough.
Fan Blade and Housing Degreasing
Grease on a fan wheel builds up unevenly. Think of a ceiling fan with dust caked on two blades and not the others: it wobbles, gets loud and wears out faster.
We scrape and degrease each blade and the housing interior. That cuts down on fire risk and puts less strain on the motor.
Belt and Motor Check
Grease and heat are hard on belts and bearings. While the fan is open, we look at the belt, pulleys and motor and note anything worn, loose or cracked.
Once the fan is back together, we test it to confirm normal speed and airflow. A weak fan lets smoke and grease hang in your kitchen.
Rooftop Grease Containment
Grease that escapes the fan can eat into a roof membrane and lead to leaks you’ll pay a roofer to fix. Wash water from a cleaning can do the same if nobody catches it.
We lay protective mats under access points, put barriers around the fan and cover drains. Collected grease and wastewater are disposed of properly.
Rooftop Fan Cleaning Process
Step 1: Lock Out and Set Up
We power the fan down, confirm it can’t restart, and lay containment around the base and drains.
Step 2: Open the Fan
The fan is tipped open or disconnected so we can reach the wheel, housing interior and the duct below it.
Step 3: Clean and Inspect
Blades and housing are scraped, degreased and washed. We look over belts, pulleys and the motor as we go.
Step 4: Reconnect and Test
The fan goes back together and gets run. Speed and airflow are checked, and the results go on your service report with photos.

On the same schedule as the hood and duct it serves. NFPA 96 sets that by cooking volume: monthly for solid fuel, quarterly for high-volume lines, twice a year for most restaurants and once a year for light use.
We usually clean hood, duct and fan in one visit, since grease moves through all three. If your hood was cleaned recently but the fan was skipped, we can come out for the fan alone. Ask us when you call.
It usually means the fan and duct are carrying more grease than they should, or the containment around the fan is full or missing. A cleaning removes the source. Tell us about any roof staining and we'll note it on your report.
Sometimes. A wheel with uneven grease buildup gets out of balance and rattles. If the noise comes from a worn belt or bearing, we’ll write it up so you can get it repaired.
Yes. Let us know whether access is by interior hatch, fixed ladder or an extension ladder, and whether we need a key or a landlord’s okay. Roof access is one of the factors in your quote.
In a full-system visit, yes. Most single-hood kitchens in Houston pay $150–$500 per cleaning. Fans that are hard to reach, or several fans on one roof, cost more.
