It seems like enclosed valley will trap all the debri and ice, this will allow shingles to rust.I can think of few different designs that are more practical.
@@dishapatel365 The #1 Thing you need to do is get the CDX clean (meaning flat with nothing sticking up) then use a good Ice and Heat underlayment out to the edge of all the trim. Then add the roof. Solves all you potential unseen issues for future leaks. Nip it in the bud early and the roof will last forever.
