I've had an L shaped extension built around my house and the roof has a 9-10 degree pitch
I've had leaks coming through and had the work done again both times OSB boarded
counter battens and also double up on breathable membrane. with the slates having a
bigger overlap. This was in December 2014 I'm still waiting to move in and have had many
problems. The builder has re-roofed this section and used permavent easy slate strips
this has got rid of most of the leaks but I still notice damp patches during heavy rain.
One possible solution ive been thinking and been told about is to strip down to the OSB
board and use torch on felt underlay a high quality one like Icopal Torch Safe T.A
and then felt over with Icopal tecnatorch sand. Then counterbatten and use torch on felt
over the vertical battens for further protection and then batten again and fix the sales again as
just for aesthetics the primary roof would be the torch on felt.
Would this help. This has been a big stress for me. Any advice appreciated.
Thanks
