Rated 5 out of 5 by from Gavin High quality roofing felt. It’s going to be on the roof for many years so it’s worth fitting a high quality durable product Why when writing a review do you need a nick name? Not at school now

Rated 3 out of 5 by from Membrane This seems like a good membrane, is tough and doesn't tear easily but beads water well and cuts with a Stanley knife nice and easy. Can't comment on longevity yet. My only complaint is that the first roll I bought was grey on the underside but the second is black so it doesn't look uniform and I'm half way through the project, mainly a cosmetic thing but a bit annoying that it's no longer the same as in the picture.

Joint tape

Is there an appropriate tape for taping the joints?
Asked by: DIYDicky

Can this also be used as a vapour barrier on walls as well as underlay on roof?

Asked by: Sparrows
I've used it on my garden room/shed/workshop it's the same as the more expensive Tyvek paper building wrap, it's quite thick, difficult to tear. Same thing as a roof, keep the wind and rain out being waterproof but allows moisture out of the roof/building.

Is this a replacement for the felt under roof tiles?

Asked by: Aid1473
Hello Aid1473, Yes, this breathable membrane would be installed under the roof tiles in place of a traditional felt. If you are in any doubt about which membrane is right for your job, we would recommend consulting a roofing professional. Thank you for using Q&A
