Best Roofing Options for Restaurants and Commercial Kitchens
Running a restaurant is demanding. From staff management to food safety, there’s no shortage of challenges. But one area many owners and property managers overlook is the roof.
Unlike standard commercial buildings, restaurants and commercial kitchens put unique stress on their roofing systems. Grease, heat, and constant rooftop equipment maintenance all combine to make roofing a critical part of the operation. Choosing the right system, and maintaining it properly, can prevent leaks, health code issues, and costly downtime.
Here’s what you need to know about the best roofing options for restaurants and commercial kitchens in California.
Why Restaurant Roofs Are Different
- Grease Exhaust: Kitchen vents release grease particles that settle on the roof, breaking down membranes.
- Heat: Exhaust fans and rooftop units create hot spots that speed up wear.
- Foot Traffic: Frequent service calls for HVAC and kitchen equipment mean more wear and tear.
- Moisture & Cleaning Chemicals: Water and cleaners from exhaust hoods can accelerate roof degradation.
Because of these factors, not all roofing systems are suitable for restaurants.
Top Roofing Options for Restaurants and Commercial Kitchens
Modified Bitumen Roofing
- Why it works: Durable and resistant to foot traffic. Multiple layers provide extra protection against leaks.
- Pros: Affordable, proven track record, easy to repair.
- Cons: More vulnerable to grease without protective coatings.
EPDM Roofing (Rubber Roofing)
- Why it works: Flexible, long-lasting, and relatively easy to install and repair.
- Pros: Resistant to UV damage, performs well in California’s sun.
- Cons: Black surface can absorb heat unless coated; not as grease-resistant without protection.
PVC Roofing (Polyvinyl Chloride)
- Why it works: Highly resistant to grease and chemicals, making it one of the best choices for restaurants.
- Pros: Long lifespan, reflective surface for energy savings, excellent grease resistance.
- Cons: Higher upfront cost than EPDM or modified bitumen.
Protective Roof Coatings
- Why it works: Adds a reflective, protective layer on top of existing systems. Helps guard against grease, UV, and heat.
- Pros: Extends roof life, improves energy efficiency, cost-effective upgrade.
- Cons: Not a solution for severely damaged roofs; must be applied to a sound system.
Key Features to Look For in a Restaurant Roof
- Grease Resistance
- PVC is the strongest option; coatings can add extra protection.
- Durability Against Foot Traffic
- Choose reinforced systems and add walkway pads near equipment.
- Easy to Maintain
- Repairs should be straightforward and minimally disruptive.
- Energy Efficiency
- Reflective surfaces help reduce cooling costs in hot kitchens.
Maintenance Tips for Restaurant Roofs
- Install Grease Containment Systems: Prevents grease from spreading across the roof.
- Schedule Quarterly Inspections: Restaurants need more frequent inspections than standard commercial roofs.
- Add Walk Pads: Protects the roof from constant technician foot traffic.
- Clean Regularly: Remove grease, debris, and standing water quickly.
Final Thoughts
For restaurants and commercial kitchens, the roof is more than just shelter... it’s part of the operation. A failing roof can mean leaks in dining areas, health code violations, or even forced closures.
Choosing the right system, PVC, EPDM, or modified bitumen, and protecting it with coatings and maintenance ensures your restaurant stays safe, compliant, and profitable.
