Hi All, My garage roof is made up of 8 by 4 plywood 18m then coverd with roofing felt which has been on for about 12 years and is now leeking. I would like to put some 12" by 24" plastic type tiles on this time instead of felt, After removing the old felt can i fix the tiles directley onto the plywood or do i have to battern it out with 2" by 1" then nail the tiles on
Regards Bob.
