Flat roof: abutment ventilation


ToughButterCup

Recommended Posts

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?

I appreciate the response.... looking at the product details, I see the following....

' ... 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.

The Wakeflex is an EDPM/Ali composite lead replacement product. There are tube videos on how to use it, very informative and easy to use.

Yes, Russ it is timber : but whats a pre-folded flashing?

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.
