water and ice barrier question
My parents are in their late 80's and have a roof that has very little slant to it,. plus it a vaulted ceiling inside. They had a new roof put on and because of the pitch of the roof the contractor installed a water and ice barrier product on the Whole Roof.. This spring they had very bad roof leaks from what look like the peak area and below. My question is..If a conctractor installed this water and ice barrier on the Whole Roof, from what I read it shouldn't leak? No matter what? Ice damn, snow and rain?
\
and is it important or not that if you have a water and ice barrier install should they also install the felt too?
Thank you
