Protect A1 Roofing Underlay 1 x 15m 4.5 5 17 17
Good value roofing material Easy to handle without tearing. Easy to cut and seems robust. Fixes easily with clout nails and stiff enough to look good without wrinkles or sagging without spending too much time on alignment. Recommended. 9 May 2015
Roof fix I bought one pack of this underlay as a trial to repair rips in the existing felt. It was so easy to work with that I decided to buy more packs and do the whole roof. An excellent product. 21 Apr 2015
Worked well I had to replace some torn underlay on my roof. As i had some faulty tiles and found the rain was coming through. It worked well and was easy to work with. Would definitely use again 6 Apr 2015
Protect A1 Roofing Underlay 1 What can I say, this does exactly what it says. The underlay was easy to cut and lay out, once the battens were in place it does the job of stopping any water breaching the tiles getting inside the roof. 27 Mar 2015
