Walls below a valley

I know we're all a bunch of seasoned veterans here but just in case someone with only a few years experience is trolling around here is what NOT to do on a bi-level house where an upper valley is dumping water onto the wall of the lower level.

Put the little pieces "Away" from the wall. Not up against it and as much of a whole shingle as you can get up against the wall. There is just too much water congregating in one place.

A run or two of I/W shield or storm guard installed vertically is also very helpful.

OS, The lady had contracted with another "company" and they put that silicone on the wall in an effort to stop the leak. :laugh:

It wasn't leaking at the flashing though.

There is just a massive amount of water that comes flying out of the upper valley, combines with the water accumulating on the lower roof near the wall and then all that water runs down about a foot away from the wall.

When the house was roofed, they added to the problem by putting the short pieces of shingle up against the wall instead of away from it.

So now, all that water runs down and over the places where two pieces of shingles butt together within two feet of the wall.

During the hard rains some of that "river" of water enters where the shingles butt together and especially if combined with the slightest unlevelness will track horizontally across the shingle until it reaches nails and/or butt joints.

Someone had done a shoddy repair job on the other side where yet another valley dumps on the wall. lol

I tore out both walls, removed the old flashing, installed one row of gaf storm guard vertically turning it up the wall and sticking it down, installed new flashing on top of that and re-shingled it putting the small pieces of shingle away from the walls and a long shingle into the wall.

So now there are NO butt joints under the river!

That's water that ran out from under the shingle when I lifted it up.

4 yr. old roof.
