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.

Can I use this to replace the roofing felt that has been blown off my shed roof please?

Asked by: Janere
Hello Janere, This cannot be used as roofing as it is just the insulation and will not provide a permanent seal. Thank you for using Q and A.
