Heavy duty Bought this to cover a dormer roof temporary and was surprised how light weight but thick it was. Roofer did not turn up for a week and it chucked it down but never got a drop inside. 9 Mar 2015
Excellent quality Needed some roofing felt to line the inside of my roof space to stop everything getting covered with dust and dirt. This fits the bill perfectly. It's excellent value for money, it's easy to cut but is thick and strong enough to provide excellent cover. Very pleased. 15 Jan 2015
Hundreds of uses This material was designed to replace bitumen roofing felt but it is so much more versatile than the old felt. It can protect a roof without any other covering for 6 months at least. I use a piece in the back of my estate car to protect the carpet and cover tools from view, it has been in there 5 years and still going strong. Excellent product would thoroughly recommend. 9 Dec 2014
Liner Easy to use. Although in high winds it can be a lot of fun! 20 Nov 2014
