Hi
My garage has a metal roof leaks eveywhere, it's a 6.5 by 5.5 metres sigle biulding. There are only four 5.5 metres wood beams and I can see mushroom on them, so think I need a whole new roof, joists deck boards waterproof layer....
I've done a lot of search and am confused about felt GRP and EPDM
felt won't last long time
GRP cracks and it's too cold now
EPDM needs adhesive and there is a fox family around, have no idea if they dig this, they dig a few holes in my garden
Some roofer told me 4 joists are not strong enough, should be 9 so the spacing between joists will be 600mm(now it's 1.2m) and they can biuld the GRP roof,
Is this necessary for all kind roof or only for GRP, what size joists do I need? how about the deck boards? plywood or OSB3? what thickness is needed?
I prefer EPDM but still havn't make my decision. please give me a rough price I should expect to pay, felt GRP or EPM whatever you say may help
Thanks
