So I have an ongoing leak that we're having trouble figuring out. Here's the deal... The dormer walls on the second floor of my house meet up with a roof at the bottom. The walls of the dormer are wood shake. We can go a few months with some pretty hard rain and no leaks in the pitched ceiling that the dormer meets, but then all of a sudden, it leaks randomly during a heavy rain storm. I went on the roof, sprayed the hose and was able to recreate the leak, however, all gaps seem to be secured and I can't see any visible gaps for water to leak in. In addition, I noticed a lot of the wood shake along the bottom half of the dormer seem soft and easily torn when wet and brittle when dry. Also there is no visible flashing where the roof and dormer meet. Is it possible the shake is soaking up water when soaked really good and seeping the water down the wall behind them?

Can anyone offer any thoughts?

When you say moisture barrier, do you mean what is under the cedar shake? If that is whay you mean, I belive it is tar paper. I have not removed more than a few shake since purchasing the house but from what I can tell that is what is under the shake.

If your asking what is on the shake itself, the only thing I can see is an old coat of paint... probably latex.

Any thoughts?

Tar paper would be the moisture barrier.

Then yes... tar paper is what is currently the moisture barrier. Would that eliminate the possibility of the shake absorbing the rain and coming down the wall?

The thing here is that I'm trying to solve this leak for enough time until I can afford to side the house and replace the roffing on the roof overhang that is on the side of the dormer.

Any suggestions? I there any water proofing that I can conduct on the existing shake or do you think the shake is not a real problem here?

You allready did the water test with the hose. It must be the tarpaper or flashing.
