Floating flashing or sinking roof

You have probably called for further evaluation, which is about all you can do in a normal home inspection anyway.

Hi John,

The roof is all log and hand hewn beams with mortise and tenon joints pegged togather. There was one beam about 14' away that had a check possibly even a split all the way down the middle of the 8" beam. I think this one was too far away to affect the area in question, but I do think the roof has dropped in the last 17 years.

Brian, I think the flashing was a pretty good job, they reflashed when they rebuilt the chimney and daylight was not visible from the attic space (seen that plenty of times).

Anyway, I did call for further evaluation, I just wasn't comfortable with it.

Thanks to all for your input.
