Flat Roof Drain Outlet 60x80 - length 30cm

For draining water on a flat roof, you have 2 choices, namely to feed this through the roof (with a roof gutter) or through the roof edge into a gutter. For the latter, you use a Flat Roof Drain Outlet. Draining water on a flat roof is a must, as otherwise the water will remain standing, which is not desirable.

The Flat Roof Drain Outlet with dimensions of 60 mm x 80 mm has an HDPE pipe of 60 cm and an EPDM bib (for a waterproof finish) of 300 mm x 300 mm. This EPDM bib needs to be glued with EPDM contact adhesive to guarantee a waterproof seal. The colour of this Flat Roof Drain Outlet (both pipe and bib) is Black.

Fabricating Flat Roof Drain Outlet

First of all, you before ll need to determine the location of the roof drain outlet before installing the EPDM. This is usually made in the corners of the roof edge or centred.

Next, start laying the EPDM strips until you get to the strip where you want to place this grommet. At this strip start laying until you reach the predetermined location, carefully lay the EPDM and mark with a white marker where you want to place this grommet. Then cut a hole in the EPDM at the right location with a good Snap-off knife, this is where the grommet will be placed.

Then use a good reciprocating saw to make a hole slightly larger than the diameter of the roof edge so that the pipe fits.

To install the roof drain outlet, use our EPDM contact adhesive, which you apply to both the EPDM roof drain outlet and the bib of the roof drain. You smear this over the bib (at the bottom) up to 1 cm from the edges, then press the pipe of the grommet into the hole you have just made and press the bib on. This gives you an extra business discount and a useful order overview. For more EPDM articles, also check out our category EPDM.
