Hi:
I would appreciate some advice on handling my attic situation. I have a multi-level townhouse. I have attached a drawing to show what I found up there.
I get frost all the time. I have had to have the shingles replaced because of leaks that were not due to obvious holes. Snow melts along the line of the wall before the rest of the roof.
The spaces between the rafters has been blocked with 1/4" plywood and against the wall, right up to the roof sheathing, 10" yellow batts have been placed. I assume these were placed by a 'handy-man' as the rest of the house uses pink. I found that some of the yellow was frozen to the sheathing when I pulled them down.
What I need to know is should I just cut back the yellow so I doesn't reach the roof or should I also remove the 1/4" plywood? I'm thinking the plywood/yellow insulation is preventing air from moving to the vent at the roof peak and this is the major issue causing the frost.
The unit was built in 1979 during the Alberta oil-boom so who knows how good the builder was, but I can't tell if the plywood is original or placed later.
Thanks
