My daughter is in the process of buying a house. Upon an inspection she was told that new knee walls had been built in the attic. The inspector also told her the roof is being supported by inner walls. What kind of problems could she expect and is there danger in having inner walls supporting the roof?

Cherokee,

You usually find knee walls where adjoining rooms are different heights. For example; you have an 8' ceiling on one side and a 10' ceiling on the other side. A knee wall is also called a pony wall (ever heard the term "pony up"? ; it is added to support the ends of the 10' high ceiling joists. The knee wall should also have insulation batting in it.

Roof bracing to interior "load bearing" walls and beams is required. Examples of braces are braces to; ridges, hips, valleys, and purlins. You should be concerned if the braces were missing.

Unless the inspector had specific concerns; I am not sure why your daughter was given this information without an explaination of the specific problem.

Hope this helps.
