Shed roof - felt or rubber

[clockworks]

I went for rubber for my 16' x 8' shed. Single piece, online order. Cost about £200.

Not that much more expensive than decent felt.

Are there any rubber roofing products that can be ended to felt?
My shed had a felt roof that is stuck on with bitumen making it a pig to remove, so would like to use EPDM over the felt but I think that needs to be bonded to the timber?

Knock the whole roof of, sheet it out in OSB, and stick the EPMD down to that?

That's a reasonable suggestion actually.

Yes, classicbond pro is fleece backed and can go over felt. Costs as much as my shed though.

You're right, it's not cheap is it.

I did rubber last summer and it was a breeze, managed to get it in a large single piece so no joins, easy to cut and handle. Should last longer, can't see myself using felt again.

I agree with this.

What are the advantages of felt over rubber?Is it a great deal cheaper?

I used rubber on my garage roof. A single sheet with no joins feels inherently less leaky.

Felt is cheaper….but we have now done 2 sheds with EPDM: easy to put on and feels like it will happily outlast me: gets my vote every time.

If you nail through it it leaks. Maybe not yet, but it does.

EPDM to felt is Ford Focus to horse.

Indeed

But only for a shed

I managed to obtain some Sarna from a job a few years back. Stapled it to my shed and the shed rotted well before the Sarna waned.

That looks like the stuff I did my garage with many years back, if you scroll down to "Frequently Bought Together" it also has the underlay and the primer linked. I also had tubes of mastic to use where 2 rolls joined, and where I nailed it under the edges.

So at least £275 for 12 square meters (2 rolls of each and a can of primer) compared to:

For about the same area

Although presumably you also need some kind of primer/glue to hold the rubber down?

My builder, who fitted the rubber, already had half a tin of glue from a previous job, so didn't charge me. I think he said it was about £30 a tin.
