Allproof’s Sureflow drainage grate options include a flat, dome or overflow attachment in black ASA plastic or 316 stainless steel.

Sureflow flat-roof drainage

The Sureflow roof drain from Allproof provides a drainage option for flat residential and commercial roofs.

The drain’s base is injection-moulded from PVC using a thick-gauge wall, meaning it is fully compatible with roofing membranes that are liquid, solvent and heat-applied.

The large diameter flange provides ample surface area for bonding roofing membranes, ensuring a watertight connection. The grate can be easily removed for inspection and maintenance.
