Rubber Roof Drainage Outlet – Rear Duct

Rubber Roof Drainage Outlet – Rear Duct (25cm x 8cm)

Effective Drainage for Flat and Pent Roof Cabins

Ensure efficient water drainage on your flat or pent roof garden buildings with the Rubber Roof Drainage Outlet – Rear Duct. Designed specifically for use with EPDM and Easy Roof Membrane, this outlet enables a concealed drainage system by directing rainwater away from your roof structure via the rear or side panels.

This drainage outlet is ideal when wrapping roofing material up all four sides of the roof to create a “bowl” effect, allowing water to exit through a downpipe installed beneath. For roofs with a span greater than 5 metres, we recommend installing multiple outlets for optimal performance.

Key Features:

• Material: EPDM Rubber and Plastic

• Colour: Anthracite

• Length: 25cm

• Width: 8cm

• Installation: Glues directly to EPDM or Easy Roof Membrane

• Function: Discreet drainage for hidden water exit points

• Use Case: Ideal for flat roofs, pent roofs, or dished roofing configurations

• Drainage Recommendation: One outlet per side on larger roofs over 5m span

Installation Options:

• Four-Sided Bowl Method:
  Wrap membrane over all sides, cut drainage hole, and install outlet to divert water through a downpipe.

• Three-Sided Method:
  Wrap the membrane only around three sides and under the rear overhang—no outlet required in this setup.
