Rooftop Grease Containment in Houston, TX

Houston Quality Hood Cleaning handles rooftop grease containment in Houston, TX on every kitchen exhaust cleaning we do. Grease that escapes an upblast fan, along with the wash water from cleaning it, can soak into a roof membrane and turn into leaks. We catch it at the fan and keep it off your roof.

Houston heat and humidity are hard on rooftop equipment, and a roof stained around the fan is often the first thing a landlord or roofer points out. Houston Quality Hood Cleaning provides rooftop grease containment to Houston and surrounding cities, including Baytown, La Porte, Deer Park and Channelview.

Rooftop Grease Containment That Protects the Membrane

Set Up Before the Fan Opens

Mats, barriers and drain covers go down first. Nothing loosened during the cleaning runs across the roof or into a drain.

The Source Gets Cleaned

Grease on a roof starts in the hood, duct and fan below it. Cleaning the whole system in one visit cuts down how much grease reaches the fan between visits.

Roof Conditions on the Report

If we find staining around a fan, a full or missing collection unit, or anything else that needs follow-up, it goes on your report with photos.

Rooftop Grease Containment and NFPA 96

NFPA 96 calls for grease at a rooftop fan to drain into a closed, noncombustible, rainproof collection container, and it recognizes grease collection systems listed to UL 710A. Fire inspectors and roofers both look at whether that container is doing its job.

Upblast Fan Discharge

Most restaurant roofs have mushroom-shaped upblast fans. Grease vapor that the hood and duct don't catch condenses inside the fan and drains out at the base.

When the collection container is full or missing, that grease lands on the roof. More on rooftop exhaust fan cleaning.

Containment During Cleaning

Cleaning a fan and duct sends degreaser, hot water and loosened grease downward. Without containment, all of it ends up on the membrane or in a roof drain.

We catch the grease and wastewater on the roof and dispose of it properly instead of leaving it behind.

Roof Membrane Damage

Untreated grease breaks down many roofing materials over time and can lead to leaks and costly repairs. Long Houston summers speed that up.

We don't repair roofs. If the membrane around a fan looks stained or soft, we photograph it and note it so you can bring in your roofer early.

Roofs With Several Fans

Strip centers, hotels and large kitchens can have several fans on one roof, each tied to a different hood. Each fan gets its own containment and its own line on the report.
