Rated 5 out of 5 by from Easy / clean to use Only just installed this, so can't vouch for reliability/performance yet (so have given it 5 sars, will amend if I have any problems). Nice clean, light weight and very easy to use, now I've used it I'm disappointed that I didn't have it for the last shed I built, but retro fitting would be too difficult.

Rated 5 out of 5 by from Does what it says Easy to handle, cuts cleanly and most importantly strong breathable and waterproof. Does what it says on the tin.

I am re-roofing a flat roof (very little slope) and want to use a breathable membrane beneath the cap-sheet, but need to know how to fix it. Thanks.

Hello Shed1Brum,

You could possibly use some Double Sided Membrane Tape.

Hi Daz,

Unfortunately we wouldn't know whether it is able to be used with shingle roofing or not, however if you contact our supplier Glidevale Ltd on 0161 9055700 they may be able to assist you further. We'd also recommend contacting a suitably qualified tradesperson for advice.

Hope this helps.
