I've ordered a full kit for our shed roof which I've covered in vent3 breathable membrane. The shed roof is 12mm structural plywood, will I need to add purlins to attach the sheeting to(if so what size/spacing etc?), or can this be attached directly to the roof without purlins?
The kit comes with spacers that go under the roof at the eaves, maybe these will dictate if it does....?
I suppose to minimise contact with the roof itself it should but seems a bit OTT for a shed- I was hoping to tinker with the spacings so I could catch the A frames below supporting the roof so it's got a good hold rather than just in the ply itself....
Any advice welcome and appreciated....
