House inspection and repair

We got call from lady who own 30 years old famous design Cedar home. She said house is shifting so I went down to inspected. There are few design failure, roof beam were exposed but not serious damage from weather are affected yet. Main issue was that Purlin (roof beam) were spliced in middle that has no compression beam to prevent beam to push towards in middle, also beam were sitting on post with few nails only. Timber were used in green boxed heart so it twisted as much as the beam wanted. Steel plate were added sometime later after its build that is bended.  At same time tension rod was place in between the roof beam but it was wrong, it needed compression beam or rod.

We will be placing middle compression beam and push back a roof a bid.

This example shows how important to get the structure engineer and understand how wood react down the road.
