Avoid repairing roof leaks yourself. The goal is to find the leak before the entire roof goes bad. And in our experience when a single piece of flashing extends only a few inches under the shingles especially on a long roof slope and worse on a roof that happens to slope slightly towards rather than away from the abutting vertical building wall the accumulated roof drainage water near the bottom end of the roof wall intersection will overwhelm the width of the flashing and because it is not directed back out on top of successive shingle courses it leaks into the building or building. Four inches of the metal laps over the shingles and the remaining four inches extends up the wall.

If the roof is longer than ten feet where it butts up against the house two or more pieces of flashing are overlapped and soldered to make one large continuous flashing.

Finding the actual spot where the roof leaks is difficult because water can enter the roof in one place and run down to another before it starts soaking into the ceiling. A roof leak is extremely aggravating. You know the roof is bad if shingles are missing or obviously damaged or when water stains the ceiling or walls. An ice dam occurs when snow melts and the water freezes when it hits the colder edges of your roof.

In the photo you can still see signs of an ice dam. Check for power lines or electrical wires attached to your roof near the dormer. This roof leaks during the snowy part of winter and during storms in the summer certainly due to poor flashing.
