This week we are working on a hand-scribed home that has a log cantilevered deck. This style of deck is supported by log joists that come through from the inside of the home and support a deck on the outside.
As you can see from these photos, log rot can be a real problem when the logs are allowed to get wet in a situation like this. The middle logs on this prow deck were the worse offenders.
We were hoping to be able to save these logs supports and make the deck into a flat roof, covering the supports but unfortunately, the middle few supports were too rotten to be able to do this.
After consulting with the owner, the decision was made to cut back the old support logs and cover these with a doubled 2×10 treated member. This will allow for a conventional deck to be built in the future.
It’s amazing what a problem these cantilevered decks can present. Any log left outside the drip line (eves of the roof) will rot…it’s just a matter of time.
Look for an update on this project as we progress…
