The valley of a roof is the area that gets the most impact from rain. The result is that these areas are more high risk for leaks. Ice & water shield rather than just felt should be placed inside the valley to add extra protection.

In a woven valley like this one, each shingle should extend past the center of the valley 8-12 inches and never terminate a shingle in the valley as seen here. Nails should also be placed 8 -12 inches outside of the valley allowing no penetration in the valley itself. This will minimize opportunity roof leaks in your danger zone!
