EPDM flashing?

[Aragorn84]

Hi all,

I've built a small lean-to shed against the side of my house and planned to install an EPDM roof covering.

I'm trying to figure out the detail between the EPDM and the wall. The EPDM company supplied some sort of glue which seems to be intended to stick the EPDM to brickwork, however my wall is roughcast/dry-dash rendered, i'm not entirely convinced this glue is going to work...

I'm envisaging some sort of flashing required, but not really sure on the details. Can anyone advise on the best thing to use for this? Should i be looking at some old-school lead, or is there some other option? Should i try to lap the EPDM onto the wall at all? Or just keep it on the timber deck and use the flashing to cover the gap?

Thanks

cut the rough cast back for a start . the rubber should have an upstand before any flashing

Ordinarily, you would remove a slice of render and fit the lead against the masonry and chase it into a joint. Not sure I'd go to the trouble for a shed though. Gluing the EPDM sounds appealing, for a shed, in any case.

You need EPDM flashing trims.

Cut a slot along the render and stick the trim in with polymer adhesive.

I found the trims quite expensive so made my own from some square downpipe.
