I have a home that goes from a 5:12 to a 3:12 pitch on a small extension room. It currently has about a 17 year old EPDM roof on it.
Can you apply shingles on a 3:12?
The contractor is using malarkey Vista shingles (there middle tier) and Henry Ice and Water / Synthetic, he can also use Grace Ice and Water. His idea was to double ice and water over the epdm and put shingles on, though after doing some research ice and water won’t stick well on epdm.
Would you advise ripping off the epdm and applying shingles to osb on a 3:12?
I am in MN where we get snow and cold weather in the winters.
