Anyone else struggling with the best solution for blocking ice dams when using gutters? Best practice has been recommending wrapping the Ice and Water Shield down over the fascia, while Manufacturer instructions and warranties want the Ice and Water installed on top of the drip edge. I think I have a solution and would like to share and hear your thoughts on it. For anyone that can’t see the photo I will describe it:
It’s an extra layer of flashing (gutter apron) before the starter strip. First, as usual, a drip edge, but custom made with an extended 3” leg to block ice. Then ice/water shield as usual. Then, before shingles go on, a second gutter apron with a 2” leg, then shingles. The gutter will get installed OVER the 3" leg of the drip edge and UNDER the 2" leg of the gutter apron. This will direct rain water into the gutter, it will allow the gutter to have up to 1.5" of pitch while staying behind the apron flashing, and it will block ice dams from the possibility of reaching wood.
