ToughButterCup Posted October 19, 2018 Share Posted October 19, 2018 I have a small flat roof to build. Nearly sorted everything out - one last detail niggles, though. The roof abutment ventilator. There are lots tof choose from. But the ones I have seen require a lead flashing. Is there any way I can avoid fitting a lead flashing? Link to comment Share on other sites More sharing options...

' ... Fix lead or Wakaflex Rapid Flashing in lengths not exceeding 1.5 metres, laying it into the trays and ensuring that it is firmly engaged into the channel on the leading edge of the tray...' Thanks @the_r_sole : the issue is keeping the flat roof as low as possible The end in mind is to avoid the use of lead if I can. Why? I don't really know. I will be DIYing it, so there's a good reason to keep things simple. I've never handled lead before: don't get me wrong I'm up for the challenge, but there are many others competing for my attention.

There are tube videos on how to use it, very informative and easy to use. Edited October 19, 2018 by Triassic Link to comment Share on other sites More sharing options...

Russell griffiths Posted October 19, 2018 Share Posted October 19, 2018 If that is timber cladding in your pic then why use lead, you could get a flashing pre folded and dress it into a cut in your durosol wall and batten and clad down to it.

From a sheet metal company, zinc coated, folded to your design imagine you had a metal roof and needed a flashing bent to a certain size shape you could probably get a fibreglass one also that is made to look like lead, just like they use on the fibreglass roofs. What is your flat roof covering. Link to comment Share on other sites More sharing options...
