The back of the chimney without a cricket does not have ice and water shield before laying in shingles and the aluminum flashing? This is where explanation could have been more detailed. Did I understand correctly that you recommended Ice & water shield on the top most part of the flashing?
edge of lower metal meets old brick wall installer is OOB. Intersection of metal/brick is leaking inside. (We used inspection camera inside. Can't see it on outside.) Which method should we use?
How would I go about doing this if our home has stucco exterior walls...? Our dormers are awful and water runoff is getting underneath or in between, not running into the gutters as it should!
Flashing should be applied before stucco is applied. Water penetration will always happen with stucco, even when painted. There should be a rubber membrane layer on the wall, a metal lathe on the bottom of the wall and that should be filled with mortar and will allow water to fall onto roof vs inside home.
