I am having some trouble with the roof on the rear of this house.

The rear roof is standard 3-Tab Shingle over 15# Paper and OSB,
probably about 4 Years Old.

I was up in the attic the other day towards the rear pitch and the
OSB is saturated with water to the point that it is dripping on the
insulation below(Snow piled on the roof). There is sufficient
venting in the attic. I want to fix the problem on the rear roof but
am not sure how to keep the water from penetrating given the gentle
slope:
1. Tearoff, new osb, ice guard over all the sheathing, 30-Year
Shingles. 2. Tearoff, new osb, Rubber Roof?

Thanks in Advance,

My guess is the flashing at the top where it meets the wall has a
problem or is totally missing.

Dia duit

I agree with Joseph, the flashing is probably done poorly or missing.
