Four 5m lengths of used roofing felt (Strathkinness KY16)
Don’t know if this is of use to anyone. The felt has been on a shed for over 10 years but seems in reasonable condition (makes me wonder why I changed it) and still has a few more years life in it. No cracks. Little moss. The 5m (15 ft) lengths are intact.
This offer has been gifted to someone and is no longer available.
