Rated 4 out of 5 by from Great product The felt under my roof tiles had disintegrated and had large holes so wanted a cost-effective replacement. As the roof is three storeys up, carrying and fitting this lightweight roll was a doddle. Can't comment on durability but it certainly is easy to install.

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.

Hi, can i use this felt under a natural slate roof?

Asked by: Anonymous

My garage roof currently has felt shingle tiles and leaks slightly (more so in the wind). Would this product work as an underlay as well as or better/worse than underlaying with normal felt?

Asked by: Anonymous

Which Adhesive?

Need to cut in around a dormer window on a timber summerhouse then use shingles too finish. Would need to use an adhesive/ bitumen based product to rejoin all the cuts etc to prevent water ingress. Which product is suitable please.
