Grease-rated at the hood
Membrane specified to survive grease discharge instead of dissolving around the exhaust fan.
Capital planningRestaurant Roofing, at a glance
Kitchen exhaust puts grease on a roof, and grease destroys most membranes from the surface down. John Beal Roofing specs grease-resistant PVC around hood zones, rebuilds the curbs, and schedules work between service hours. Call (314) 429-6000.
What we look at on a restaurant roof
- Membrane degradation around the kitchen exhaust fan, the number one restaurant failure
- Grease containment so a new roof does not fail the same way
- Make-up air and hood curb flashing
- Scheduling around service, with hot work kept clear of exhaust
How We Work It
Built Around Your Operation
Containment corrected
Hood discharge captured properly so the new roof does not fail the same way the old one did.
Between services
Work timed to the gap between lunch and dinner, or overnight, so you keep serving.

Roofing Around A Kitchen That Cannot Close
Restaurant roofs fail in one predictable place. Grease-laden vapor from the kitchen hood discharges onto the roof surface, and over years it degrades the membrane around the exhaust fan until the area is saturated and soft.
A membrane has to be grease-resistant in that zone, and the hood needs proper containment so discharge is captured rather than running across the field. Replacing the roof without fixing that just restarts the clock.
The other constraint is service. There is no good time, but there is a least-bad one, and it is usually between lunch and dinner or overnight. Rooftop grease, hot work near exhaust and fire-suppression coordination all get planned before crews arrive.
Common Questions
Can you work after hours or on weekends?
Yes, and for restaurants that is usually the only workable option. We work overnight or between lunch and dinner service.
How do you protect what is underneath?
Only as much roof is opened as the crew can dry in that day, and we keep debris and fumes away from kitchen intakes and the dining room.
Do you handle the rooftop mechanical units?
We coordinate lifts and disconnects with your mechanical contractor and rebuild the curbs around hood exhaust and make-up air units.
What is the lead time on a project this size?
It depends on the system and material availability. Grease-rated membranes can run longer, and we tell you at scope.
Do you offer maintenance after the install?
Yes. Twice-yearly inspections with the grease discharge zone checked specifically, because that is where the next failure starts.
