If you’re hoping to route a vent or flue through your roof, Seldek metal flashing is a one-stop solution that’s watertight and easy to install. The Seldek Aluminium will not stain or corrode gutters and roofs. When fitted to steeper pitches the design allows for a twisted cone.
Suitable for a range of pitches and temperatures
Out of the packet, the flashing has a built-in 20-degree pitch – but the black EPDM cone is flexible – allowing for the huge range of angles that more steeply pitched roofs can create – up to 45-degrees. As well as being extremely flexible, the EPDM also allows for a range of temperatures – suitable for pipes between -50°C to 115°C constant and 150°C intermittent.
Trim to fit
The EPDM cone is designed to be trimmed to fit your paperwork on site – and is suitable for pipes with a diameter of between 50mm and 170mm.
The Seldek metal flashing can be easily installed – assuming you have the necessary equipment needed to safely access your roof and some basic roofing knowledge.
To complete the job, you’ll need some tin snips, a sand hammer, and a marker.
First, measure and cut the rubber cone according to the size of the pipe you’re working with. Remember, the rubber will stretch slightly so it’s better be slightly under. You’ll need to remove the tile that the pipe will pass through – then slide the flashing over the pipe when it’s in place. You may need to apply water to help it slide – but avoid using any lubricant as it could cause the rubber to perish.
You should snip 40mm wide vertical tabs in the sheet to tuck under tiles either side of the gap you’ve created, then use the sand hammer to make sure the profile of the aluminium matches the surrounding roof. With the upper part of the metal flashing apron tucked under the tiles above when they’re replaced, you’ll create a watertight flashing that seals around your pipe perfectly.
