More about drip edges
This article expands on what I wrote here:
Old rock lath and plaster ceiling is supported by a two by four and tape. This ceiling was in good shape before the roof was replaced.
The rake board (the fascia board on a gable is called a rake board). The metal wrap that covers the rake boards creates a water funnel, like here in question 8303. This can be corrected by covering the top with a drip edge. This practice of the aluminum water funnel is widespread and it needs to stop. It may take a few years before the ceiling starts collapsing like here.
Edges of shingles are curled down, running water into the fascia board. To make matters worse, the fascia is covered with an aluminum wrap, deflecting water into the ceiling. A drip edge, known as a gutter apron, would have prevented this leak.
Ceiling is sagging around the fireplace. The counter flashing isn't stair-stepped into the brick joints, and the flashing on the back isn't angled into the brick joint. After 10 years or so of drip, drip, drip, the nice lath and plaster ceiling is failing. This is another common practice these days that has to stop. Sticking on a strip of sheet metal and gobbing on caulking at the top isn't adequate.
What is going to happen with this house ?
The homeowners filed a claim on their insurance. I doubt the insurance company will pay. Insurance doesn't cover gradual damage. I need about 20 grand to replace the ceiling. In the event of sudden damage, like an ice dam, the insurance is liable for the damage. Some of these companies fight tooth and nail not to pay. In the event the insurance admits liability, usually they try to substitute cheap drywall.
Thanks so much dear readers, for reading all these years, and for all the comments.
