Rooftop Grease Containment

Rooftop Grease Containment for Arizona Restaurants — Protect the Roof Before It Costs You One

In Arizona, what happens to grease on the roof is a bigger problem than almost anywhere else. UV and 160°F surface temperatures break exhaust grease down into an acidic sludge that dissolves roof membranes, then monsoon storms wash it across the roof and down scuppers into parking lots and storm drains — a municipal stormwater violation. We install and service containment systems that catch grease before it costs you a roof.

What's Included

  • Grease boxes and catch pans matched to your fan
  • Absorbent pillow and pad systems around the fan base
  • Perimeter guards for problem runoff areas
  • Media swaps synced to your hood-cleaning schedule
  • Roof-condition and runoff assessment
  • Documentation for landlords and property managers

What Happens to Grease on an Arizona Roof

Exhaust grease that reaches the roof doesn't just sit there. Arizona sun and heat oxidize it into an acidic sludge that attacks single-ply roof membranes and asphalt alike. Then the monsoon arrives: heavy seasonal storms sheet water across the roof, carrying that grease into scuppers, down the building, across parking lots, and into the storm drain system.

Roof Damage, Odor, and Stormwater Violations

No containment means three bills waiting to happen: premature roof membrane failure (a five-figure repair), persistent rancid odor around the building, and potential stormwater-runoff violations when grease enters municipal drains. Containment is a few hundred dollars of media a year against any one of those outcomes.

Containment Options

We match the system to your fan type and duct penetration: grease cups and catch boxes at the discharge, absorbent-pillow systems around the fan base, and perimeter guards where runoff already stains the roof. The goal is to capture grease at the source and keep the surrounding roof surface clean and dry.

NFPA 96 and Grease on the Roof

Fire inspectors look up, not just in. Heavy grease accumulation on the roof around a fan is both a fire-spread path and a red flag that the system isn't being maintained. Keeping the roof clean supports the same compliance story your interior cleaning and documentation tell.

Ongoing Service Synced to Your Cleaning Schedule

Containment media only works if it's swapped before it saturates. We change pads, pillows, and cups on the same cycle as your hood cleaning, so it's one schedule, one vendor, and one invoice. During monsoon season we can tighten the interval on high-output kitchens.

What Landlords and Property Managers Require

Most commercial leases put roof protection squarely on the restaurant tenant, and property managers increasingly require documented grease containment. We provide the service records that satisfy your landlord and keep your roof — and your security deposit — intact at lease turnover.

Rooftop Grease Containment — Common Questions

Intense UV and rooftop heat turn exhaust grease into an acidic sludge that degrades roof membranes faster, and monsoon storms then wash it into storm drains — creating both roof-damage and stormwater-violation risk that milder climates don't face as sharply.
It depends on your kitchen's output, but we sync media swaps to your hood-cleaning frequency and tighten the interval during monsoon season for high-volume kitchens so pads never saturate and overflow.
Yes. Fire inspectors treat heavy rooftop grease as both a fire-spread path and evidence the system isn't maintained, and grease entering storm drains can trigger municipal stormwater penalties.
