We have had a problem in our 3 year old home for some time. Our home
has a brick front, with two bay windows, each covered with an extruded
metal roof. During windy, driving rain, the roofs would leak,
eventually causing water to enter the residence.
The metal bay window roofs are attached to the house with roofing
cement. There was not line cut into the mortar, and the roofs /
flashing were not tucked into this line.
We cut drywall inside the house, allowing us to see the inside of the
bay roofs. We can now water test and see where the water enters.
The brick wall just above the left bay window has weepholes installed
directly above the bay roofline. The brick wall above the right bay
window had no weepholes installed (although the flashing was there).
We notified the builder, who had the mason come and insert weepholes.
These weepholes were placed a full course above the bay roofline (as
that's where the flashing was).
The roofer has tried putting new roofing cement on, etc., but when it
rains "just right" or when I water test it with a hose, we still have
some water coming in.
He said that he could cut a line in the mortar above the right bay
window, and tuck the flashing / roof into it, then put roofing cement
on. But, he can't do this over the left, because the flashing /
weepholes are right above the roofline.
So, my first question is should the weepholes / flashing be directly
above the bay window roof? Or, should they be one (or more) courses
Any suggestions for dealing with this problem?
Thank you very much.
