(SERVICE OVERVIEW)

Certified Roof Grease Containment Installations

Rooftop upblast exhaust fans discharge grease vapors vertically. However, some grease condenses and drains out of the fan housing. Without a containment system, this highly acidic grease spills directly onto the roof surface, causing severe roofing membrane decay, water leaks, and structural fire hazards.

Crossaire installs professional rooftop grease containment systems. We place hydrophobic filter barriers around the fan base that allow rainwater to pass through while capturing and trapping kitchen grease. This keeps your roof clean, prevents fire risks, and preserves your roof warranty.

(CRITICAL HYGIENE & SAFETY)

Why Roof Grease Containment is Vital

Allowing kitchen grease to drain onto your roof causes structural damage and code violations. Here is why containment is essential:

Protect Roof Membrane

Kitchen grease contains acids that break down asphalt shingles, TPO, and EPDM roofing membranes, leading to costly water leaks.

Reduce Fire Risk

A grease-soaked roof is a severe fire hazard. Fire can spread across grease-saturated roofing materials. Containment isolates this risk.

Protect Roof Warranties

Most commercial roofing warranties explicitly exclude grease damage. Installing a certified containment system protects your building warranty.

(SYSTEM WARNING SIGNS)

Signs Your Roof Needs Grease Containment

Inspect your roof regular. If you notice any of these signs of grease drainage, schedule containment installation immediately:

Puddles of Grease on Roof

Pooling oil or grease around the base of your upblast fan is a clear sign of system failure.

Warped Roofing Material

Roofing membrane that looks bubbled, soft, or spongy has been degraded by grease acids.

Clogged Rooftop Drains

Grease runoff washing into roof drains causes blockages, pooling water, and leaks.

Empty Grease Drain Port

An open drain port on the fan housing with no collection system allows oil to drip directly onto the roof.

Health & Fire Violations

Inspectors issuing warnings regarding rooftop grease accumulation and environmental safety.

Active Water Leaks

Water dripping into the kitchen ceiling directly below the rooftop exhaust fan point to membrane rot.

(SERVICE SCOPE)

What Is Included
in Our Service?

Roof Grease Containment Systems Installations Showcase

Hydrophobic Filter Installation

Fitting specialized filters that repel water but trap oil and grease molecules.

Grease Collection Boxes

Mounting heavy-gauge steel collection boxes directly to the upblast fan drain spout.

Protective Roof Mats

Installing multi-layered grease mats under the fan base to protect the roof surface.

Exhaust Fan Drain Cleanout

Clearing out grease drain lines and spouts on the upblast fan to prevent blockage.

Containment Frame Mounts

Securing metal containment frames around the fan curb to keep filter mats in place.

NFPA 96 Compliance Review

Ensuring your rooftop grease collection conforms to fire and environmental safety codes.

(BUSINESS VALUE)

Benefits of Regular Maintenance

Keeping grease off your roof prevents structural damage, fire hazards, and regulatory issues:

Prevent Roof Rot

Eliminates grease-driven chemical decay of TPO, EPDM, and asphalt roofing membranes.

Rainwater Separation

Hydrophobic filters let rain run off cleanly while locking grease inside the collection mats.

Reduced Fire Spread

Eliminates grease trails on the roof that can feed and spread fires across the building.

Lower Leak Risk

Preserves the roof's waterproofing seal, preventing water leaks into the kitchen below.

Compliance Ready

Satisfies fire code NFPA 96 and environmental codes prohibiting grease runoff into stormwater systems.

Avoid Costly Repairs

Saves thousands of dollars in commercial roof repairs and structural membrane patches.

(HOW WE WORK)

Our Step-by-Step Process

We employ a meticulous, structured process to ensure safety, efficiency, and zero mess left behind:

Rooftop Grease Cleaning

We scrape and degrease the roof surface around the fan base, restoring a clean surface for installation.

Drain Pipe Clearance

We clean the exhaust fan drain port and pipe to ensure grease drains freely without clogging.

Base Mat Placement

We lay down a multi-layered, fire-resistant grease-absorbing mat base around the exhaust curb.

Metal Frame Mounting

We secure a stainless steel containment frame over the mat base, keeping filters locked in place.

Hydrophobic Filter Install

We fit specialized hydrophobic grease-retentive filter layers into the metal frame.

Spout Box Attachment

We attach a grease box to the fan drain spout, adding grease-absorbing pads to catch dripping oil.

Final Inspection

We verify the system allows water runoff, secure all components, and take completion photos.

Frequently Asked Questions

Got questions about Roof Grease Containment Systems Installations schedules, compliance, or logistics? Find detailed answers below:

NFPA 96 mandates that commercial exhaust systems drain grease safely into approved containers. Grease cannot drain directly onto the roof. Containment systems are required to prevent fire risks and roof rot.

Commercial kitchen grease contains animal fats, vegetable oils, and acids. When it touches membranes like TPO, EPDM, or tar-and-gravel, it chemically degrades the material, causing it to swell, blister, and rot.

Hydrophobic filters repel water but absorb oils. Rainwater passes through the filter cleanly, but fats, oils, and grease are captured and trapped within the filter media, preventing roof pollution.

Yes. Most commercial roof manufacturers (like GAF, Johns Manville, Carlisle) exclude damage caused by animal fats or grease from their warranties. Installing containment protects your roof warranty.

Filters and mats should be inspected and replaced every 3 to 6 months. High-volume kitchens (fast food, charbroiling) require quarterly service, while low-volume kitchens may only need semi-annual changes.

Yes. We scrape and degrease the roofing area around the exhaust curb before installation to ensure the new containment system sits on a clean, solid surface.
