Total and utter garbage...use at your own peril as it actually becomes hygroscopic after time plus has shocking UV protection.
By the time you have bought insulation and decking it starts to make the £33 per square meter insulated box profile look very cheap. It would probably outlast any of the roof coverings.

how do you seal the bottom edge where it meets the gutter? so the insulation isn't exposed?
need a new roof here soon and want to use those insulated sheets..... but there's a place at the other end of the road and their insulated roof is full of rats :-o
it's a garage and they don't really care... but can't have that happening here
I'm struggling to think of something that'll seal the ends and won't trap water
I want the sheets that are flat on the inside and corrugated outside...
my only real idea is cut them so the outside is an inch longer than the inside then have some trim laser cut and then bent at 90' so it overlaps the inside of the roof covers the insulation and fits around the profile of the outer sheets.... seams like a lot of faff tho

I am amazed to find that the factory is just up the road from me, so I may be paying them a visit. I may be doing my kitchen roof in those. It seems to offer the extra insulation that I want together with a durable finish. I must be missing something important, but it looks like the ultimate answer.

its a foam trim back at the front edge
then left as is
but i prefer a trimed to profile angle plate that the insulation sits upon and butts up too then silicone the underside of the trimed to the roof edge
as it looks better
then run a thick bead of silicone under the roof sheets as they will stop blowback and cause a drip edge under the sheets
seal your cut edges and you should be fine

I had steel roofing on my previous garage lasted me 26 years with no problem and no signs of corrosion, I also cut a hole in it and welded in a flu for a wood burner

For anyone else considering an EPDM roof, do NOT try and save money by using PVA raher than the proper glue. The correct adhesive is a 1K PU which means that it will stay stuck down and not start lifting in the wind. The proper stuff is about twice the price of PVA, but when compared with the overall cost of the roof, any joy at the saving made by using PVA will disappear faster than my beer on a hot day when you realise you have to re-do your roof...

It stays sticky for ages too, i used a paint roller to put mine down and you can still stick the roller to the wall over six months on.

Yes and what can happen is the rubber stretches across the roof area and forms a ridge just before the solvent glue on gutter side stopping water getting off the roof as you lose more than half of that 4" under the trim (depending on type).. 9" and its stuck further back from edge stopping the stretch ridge forming.

grp is not the type you should be walking on after its done
never mind storing on it
if you continue to do so put torch on felt at least with the sun it will remelt and seal itself
