Hi Im new here so any help appreciated,
old (at least 12yrs) north facing 8'x12' felt flat roof cracked in places not yet leaked inside?this 'summer'
My plan is to lay 100/ 120 pir foil faced insul over the ex felt, osb over this, then epdm waterproofing. My questions are:
is it ok to use ex felt as vapor check?
can i fix osb through pir into ex deck joists thinking about any probs with restricted expansion? also plan to fill any gaps from top of bwk to underside of warm deck,
Thanks in anticipation jg61
ps sorry if answers in older posts i did do a search first, honest
