Internal Flat Roof Drain: questions answered by Forti Nova
What is Internal Flat Roof Drain used for?
Match 68mm, 100mm or 110mm to the designed rainwater pipe and drainage capacity. The roof must fall to the drain, and the EPDM must be formed into the flange with compatible detailing products.
What should I measure before ordering?
Check every listed diameter, opening, pipe connection, roof build-up, outlet direction and available depth.
Does the roof need a fall?
Yes. The deck must direct water to the outlet and the downstream rainwater route must remain clear.
How is EPDM sealed around it?
Use the approved flange, primer, flashing or patch detail. Do not rely on general sealant alone.
Will an outlet stop ponding?
Only with correctly formed falls, adequate capacity and regular maintenance. The component cannot correct a backfall.
How should it be maintained?
Inspect regularly and after severe weather. Clear debris and check the surrounding membrane detail.
Can Forti Nova check compatibility?
Yes. Send dimensions, roof build-up and photographs before ordering.
