Felt over Waterproofing underlayments?
I just added a 26 x 40 garage on our new house, and I plan to shingle this roof myself. The main house was to complicated for me to tackle. On the garage their is 3 dormers, I plan on using Owens Corning wetherlock on the eves, ridge, cover the whole roof on the dormers, up the rake wall on the dormers and the fronts were the walls come out of the roof. But I am not sure if I should cover the wetherlock with felt after or just over lap the edges of the wether lock.
