Rooftop Grease Buildup: Causes, Risks, and How to Prevent It
Rooftop grease buildup is a common (and often overlooked!) issue in commercial kitchens. If your commercial kitchen exhaust hood system isn’t properly maintained, grease can escape through the system and accumulate on your roof, leading to safety hazards, code violations, and costly damage.
Here’s what causes it, and how to prevent it.
What Causes Rooftop Grease Buildup?
Your restaurant hood system is designed to capture grease-laden vapors during cooking. However, not all grease is contained. Over time, excess grease travels through:
• Hood filters
• Ductwork
• Exhaust fans
Eventually, this grease can reach the rooftop, especially if there are system inefficiencies or maintenance gaps.
How Grease Escapes Your Exhaust System

Common causes include:
• Filter Inefficiency: Dirty or clogged filters allow grease to bypass capture
• Duct Accumulation: Grease builds up and moves through the system over time
• Fan Base Overflow: Excess grease collects and spills onto the roof
