Yesterday I inspected a home in a high risk termite area when in noticed property next door and could not resist taking a picture. Why? A very large roof line dip was screaming “something is wrong”

What could it be? What has caused this roof to sag so badly? There are three possible explanations:

The first one is that the owner has interfered with the roof structural support. This is not all that uncommon. People do cut rafters or remove props.

The second is that the roof frame was built with a defect and the roof has simply sagged

Third and the most likely is termite damage to roof frame

If I was the owner I would be getting professional building and timber pest inspection
