hello ben,
well i'll start by saying that you need to forget about the felt thats
sort of like the vcr compared to dvd
have a new grp roof it lasts forever its not effected by the change in
weather and with the felt you can almost rest assure you'll be paying
out again.
many people are having garage roofs,flat roofs
asbestos roofs replaced with grp roofs.
if you need more advice on where to look for this service contact me
