Leaf catcher flat roof

When you plan to cover a flat roof with high-quality EPDM or roof leather from Wovar, you also need to take drainage into account, for this purpose Wovar has both Flat Roof Drain Outlets and roof penetrations in its range. The most commonly chosen rainwater drain at Wovar is the Round EPDM roof drain outlet, which is suitable for both an EPDM or roofing membrane and is easy to install. Of course when you drain the water you want to prevent leaves, pebbles or gravel from getting into the gutter. To prevent this, Wovar has the leaf trap flat roof in its range.

This Plastic Universal leaf trap is suitable for all round roof penetrations with a diameter between 75 - 160 mm. You can easily place it without fasteners, you only need to place the gutter first (which we explain below) and gently press the feet after which you can place it in the gutter, because these feet go back to the original position it will clamp in the pipe and stay in place. This quickly and easily prevents leaves, gravel or pebbles from entering your roof drain outlet.

Roof drain installation step-by-step

First of all, you before ve already determined the location of the EPDM roof drain outlet. The most common locations are in one of the corners of the roof or in the middle of the sides next to the roof edge. Keep a minimum distance from the roof edge of 30 cm.

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 use a white marker pen to indicate the location, this can be done by drawing a cross,

  where you want to place this grommet.

Then finish laying the EPDM. After this, you place the EPDM cuff, you can easily glue this to the location with our EPDM contact adhesive. Next, use a hole saw (or a Snap-off knife) and use the punch marks on the cuff to make the hole with a Snap-off knife, then use a good TCT hole saw that is slightly larger than the roof grommet to cut a perfect hole. This is where the roof drain outlet comes through, thanks to the thin cuff which is perfectly placed, the EPDM is completely waterproof and the roof drain outlet is perfectly seamless finished after installation.

To install the roof drain outlet, use our EPDM contact adhesive, apply it to both the EPDM roofing and the bib of the roof drain outlet. 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. Use a pressure roller to press the bib well onto the EPDM for a perfect and waterproof seal.

To install your Universal leaf trap, simply press the feet, gently push it into the HWA pipe, release it and it will clamp into the pipe and sit in place.
