36” X 30” Waterproof Aluminum Roof Access Hatch - Bilco
Can you install a roof hatch on a green roof? Yes, you can! Access Doors and Panels recommends Bilco’s S-50VM Waterproof Aluminum Roof Hatch as a great solution for green roof access due to its weathertight, corrosion-resistant properties and waterproof gasketing. Use this innovative model on flat or sloping roofs – just make sure the hinge side runs parallel to the slope. If there’s already a damaged roof hatch in place, that’s okay too – Bilco’s S-50VM roof access hatch allows you to replace a damaged roof hatch without re-roofing. The low-profile VersaMount curb features a built-in flange and apron and an innovative anchor clip system to ensure a fast, secure, and weather-tight installation over an existing curb. See it in action!
Why is S-50VM a Good Choice for Green Roofs?
Energy Efficient: S-50VM’s overlapping cover design, full welded corners, EPDM rubber gasket, and fully insulated cover and curb ensure weather tightness and energy efficiency.
Corrosion-Resistant: S-50VM has a waterproof EPDM rubber gasket and is corrosion-resistant aluminum which would work for a green roof where moisture is a concern. Even the hardware is corrosion-resistant!
Waterproof: EPDM rubber gaskets remain waterproof in harsh environments and maintain flexibility at low temperatures. EPDM gaskets also resist ozone, wear, and aging. EPDM's waterproof nature and all-weather resistance make it an ideal material for sealing the seams.
Fits Over an Existing Curb: Use S-50VM as a replacement roof hatch cover; Simply remove the cover from the damaged hatch and place the Versamount hatch on top of the existing curb.
Weathertight: The low-profile curb features a built-in flange and apron and an innovative anchor clip system to ensure a fast, secure, and weathertight installation. 
Easy to Operate: S-50VM is engineered with compression spring operators to provide smooth, easy, one-hand operation, regardless of size. The automatic hold-open arm locks the cover in the open position to ensure safe egress.
Secure: The aluminum construction includes an 11-gauge aluminum frame, a cover with fully welded corners, and an 18-gauge corrosion-resistant aluminum cover liner. Heavy gauge construction and positive latching mechanism maintain building security.
