Can someone post a picture or describe this process

What is 'sistering a rafter'. Please explain

Tick

You put another rafter up along side and nail them together. A couple of nails about every two feet.

Thanks hk for explaining. Is that done if the proper size of rafter isn't available ?

Tick

No, it is usually done to replace or repair defective or damaged structural member.
