Grease on the Roof: The Damage Nobody Budgets For

Grease on the Roof: The Damage Nobody Budgets For

Ask a roofer what kills restaurant roofs and the answer comes fast: grease. The fan throws it, the roof catches it, and the damage compounds quietly between inspections of a part of the building nobody visits.

What grease does to a roof

Cooking grease attacks single-ply membranes chemically β€” softening, swelling and separating seams. Ponded grease around the fan curb is also a slip hazard for every technician who services the roof, and grease washing off in rain heads for the storm drain, which several DMV jurisdictions treat as an illicit discharge.

Who ends up paying

Usually, the tenant. Restaurant leases commonly make the tenant responsible for grease damage from their exhaust system, roofing warranties commonly exclude it, and landlords photograph roof condition at lease events. The argument is always the same and the tenant rarely wins it.

The cheap fix

Grease containment β€” a fitted system at the fan curb with absorbent media that captures the discharge before it reaches the membrane β€” costs a fraction of one roof repair. Serviced on the same rhythm as your hood cleaning, with the media changed before it saturates, it converts a five-figure liability into a line item. Our containment service includes photographic records of the fan area at each visit: your evidence that the roof was protected, dated and continuous.
