I'm new here me and the wife just bought our first home we have lived here for about three months .
Yesterday I was cleaning the gutters and noticed that the bathroom roof looked funny as I inspected it further I seen that the roll out had a dip and the plywood is rotten under it .
The roof measures out to four sq the pitch is roughly 4 . Question is do I have to use roll out again or can I just shingle it ? Reason I ask is because this roof meets with the main roof and that part is a 10/12 pitch and it surrounds the flat roof on two sides
