Fitting a flue through a flat roof.

An easy way to mark the hole you need to cut is by using the flashing as a stencil and spray painting the inside on the roof shingles. The structure of the flat roof is wood combustible and the covering is single ply pvc.

I would need to pass a twin wall flue for the stove through a flat roof that covers a single storey section of the house. Instead of having to cut flashing materials yourself you can buy a fitting boot for your chimney pipe. Take your adjustable roof flashing and center that on the screw you ran through the roof deck. Most installers or roofing contractors will use a slate piece or a metal or lead piece that fits onto a flat or pitched roof with a gromit where the flue pipe goes through.

I and thinking about putting a woodburning stove into my new house which is currently being built. However depending on your type of roof a flat roof for example your engineer may also get a roofing contractor to check everything is properly sealed. Stovesonline can design plan specify supply and support fitting i wide range of lead nu lead alu based or epdm flashing to enable leak proof and watertight joins between your flue system chimney and roof. Once the hole is marked use your sawzall and cut the hole through the roof.

Firstly you ll want to know your chosen engineer is fully competent and experienced at fitting flues through roofs. A different type of flashing is a chimney pipe boot. Especially if it s not sealed properly.
