Been home from uni less than 24 hours and mum's already got me peeling back the shed roof. There's a bit of rotten wood to chop out and replace, easy peasy, but I don't really know what I'm doing with regards to the felt. In the past I've just nailed it down but I'm aware you can glue it or use a blowtorch which I assume is the preferable to banging nail holes thorough my nice new waterproof surface. Can someone tell me what to buy? It's about an 8' by 16' roof sloping a few degrees to one side if that matters. The plan is to order it all tonight and get it done as soon as possible before our bikes get wet.
