Protect Your Building. Prevent Water Damage. Ensure Proper Drainage for Commercial & Industrial Roofs.
For commercial buildings, proper drainage isn’t optional—it’s essential. A failing gutter or drainage system can lead to roof leaks, foundation damage, mold growth, structural issues, and costly repairs. With Ohio’s heavy rainfall, snowmelt, and severe weather, businesses need a reliable system that moves water away quickly and efficiently.
At Sentry Roofing, we specialize in commercial gutter systems, downspouts, internal drains, scuppers, and custom drainage solutions designed specifically for flat and low-slope commercial roofing. We ensure your building stays protected no matter the season.
