Drip and damage to end rafter tails

[Pablo]

This has been a thing on some of my exposed end rafter tails over the years at various houses.

There is one troublesome exposed tail on this current house. It may be peculiarity of the lower cost/spec/middle houses we poor folks end up in. Basically the builder/roofer and naked homeowner depend on the piece of shingle overhanging enough to keep the brunt of the rain water off the painted wood.

Anyway I have peeled the loose paint, allowing to dry now that our dry season is near. Will sand, then treat, primer and repaint in the summer.

I had some kind of chemical idear on helping. With both extending the drip and preventing growth by nailing a small pure zinc sheet metal square under that small shingle tab portion. We shall see!

The leading edge of that metal work is missing the the drip edge. A drip edge is a little crease which forces water to drip off the edge of the sheet metal rather than crawl underneath back towards the wood.

Repair could be sawing off the rot and replacing it with a section of PVC trim.

What metal work? There was no metal there to start, just composite shingle. You mean the piece of zinc I added? It sticks out pretty far and is at a good angle, but I could bend it down.

Ya the piece of zinc.

Some examples of what I'm talking about. Notice how the bottom edge is creased away from.

Capping

 

[Pablo]

All fixed. Power sanded, dried all summer, cleaned, treated with copper wood preservative, primed painted and capped with pure zinc sheet metal.

Fix one year later is awesome.

I guess they went for a cottage style aesthetic back then?

The standard design would have had that end cut back to the adjoining fascia board and the whole thing "bird boxed" in with aluminum capping. Having vinyl or some type of engineered wood for that fascia would be a great maintenance free solution.

Below is an ugly example of a bird box corner clad in aluminum from my house just before I had my electrical service done.

I think it is a west coast thing. House was built in 2014

In regards to the drip edge mentioned above, I would thing that 1"x1" board in contact with the shingles, where the shingles overlap in your first and last pic takes a beating without having drip edge protecting the top of it. I would suspect that wood would rot away first. Water will wick from under the shingles and onto that wood.
