EPDM Kerb Edge Trim

[Mulberry View]

We're in the process of detailing our whole house roof with a Sika single-ply membrane. We'd like a nice kerb-edge trim (ideally Zinc/Alu), but how would this be detailed if fitted after the membrane? Is this a normal thing to do? I've not approached an installer yet, maybe they'll know the answer, but asking you good chaps!

 

 

If anyone has done similar, pics would be welcome.

those fillet strip details look fiddly. 

the plastic kurb edge trim just gets nailed on with poly top nails and looks kind of naff. I guess you could nail it along the top edge so you dont see the fixings.

I'm not experienced at all with this type of roof, so any/all feedback is appreciated.

 

I guess the drip edge could be turned back up on the inside and fixed to the underneath of the 40x70 timber, they're used to that detail with Zinc roofing if I was to get trims done by a Zinc installer. But how to seal it to the Single-Ply on top? Architect seems to show another membrane.

ive only done 2 epdm roofs so am far from an expert. it looks like your epdm is set to somehow go over the top of the edge trim. with the plastic stuff the edge trim goes on last then you pull the epdm downwards and trim it with a stanley knife.

 

theres loads of videos on it by a youtube guy called oakwood garden rooms, thats how i learned it.

We had a Sika single-ply membrane installed on a small extension a couple of months ago. The edge trim upstand is a steel profile covered with a membrane. The profiles were fitted first, then the underlay and then the roof membrane was welded to the profile. The edge of the roof was just a double layer of 18mm OSB.

Thanks for this. Helpful. So the steel profile is seen from the ground I assume? Don't suppose you took any pics of it in progress?

I'll have a look, probably not from close to.

These are the best I've got, sorry.

Ours look very similar to the above, if your desperate I can nip up and take some pictures.

Shouldn't be an issue if they have welded it correctly but that up-stand should be on top of the base layer.
