Protect A1 Roofing Underlay 1 x 15m 4.5 5 15 15
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
roofing underlay This was a cheaper and more practical method of repairing the inside linings of my roof. i found the material very pliable and easy to use, no mess and is extremely strong and does the job as well as or even better than the heavy duty material. i am really pleased with the product 25 Mar 2015
Great value Easy to handle, easy to cut but tough and a good size roll for repair work. Just guessing at the performance and reliability at this stage but it seems fine so far. 12 Mar 2015
