Roof Leak where sloped roof meets siding

Hi all,

We have been in our house for exactly 1 year and 1 day, and sure enough I noticed a roof leak today!

The picture below shows the problem area where the roof slopes into the siding. Snow/ice buildup has caused water to get in either over the flashing or between the flashing and shingles. The water enters through the attic pictured (not into the wall), and runs down the wall into the garage below.

There were no leaks in the summer, so rain doesn't seem to be a problem.The house is 8 years old, and I can tell by the water marks that it had leaked in the past.



What is the best solution to this, obviously, flawed roof design? Since snow and ice is an issue, I was thinking about installing some of that heated wire that gets clipped to the shingles. This would keep the area clear of snow. I am concerned that this is only a temporary solution for a problem that is going to continually reappear. What is the permanent fix? Larger flashing? Tar the area like you would a flat roof?

Thanks for your help,

- Grant

I would try to find a way to extend the roof so it meets the other roof below.

its hard to tell without a closeup but is there a counter flashing cut into the stone?

Pulpo, I don't think I am interested in such a drastic solution. Or should I say, I am hoping this problem can be solved without resorting to that.

Jsepps,

There is a flashing that comes vertically off the roof about 6" and angles horizontally towards the stone wall about 1". There is caulking between the flashing and the stone. There is nothing cut into the stone. The mortar holding the stones is cracking because the snow piles higher than the flashing and then freezes against the stone. This is occurring on the front face of the house (just above where the eves trough is visible in the picture).

In the valley where the roof slopes into the wall, the wall is constructed of vinyl siding (not stone) and there is no flashing. The shingles butt up to the vinyl siding.

I can try to get up on the roof and post a better picture if it would make what I am describing more clear?

Thanks again,

- Grant

if there is no flashing tucked behind the siding I'm sure that's the problem. In snow country where I am I would probably put finished metal there if possible, forget the siding if its not visible
