Champia Inspector Finds Home’s Rafters Get Little Support

Undersized purlins support rafters in this attic.
Georgia Home Inspector Talks About Support!
You just never know what you will find in houses.  This house has undersized purlins supporting the rafters in the attic, according to Andrew Binosa of Champia Real Estate Inspections.

purlin: (noun) a longitudinal member in a roof frame, usually for supporting common rafters or the like between the plate and the ridge.

Not only they are undersized, to further exacerbate the situation, someone added 2×6 to it to make it appear as if they were sized properly, the ASHI associate inspector said. They thought that by adding the 2×6 to make it look like it’s not undersized would fool someone to thinking that the purlins are OK.  The 2×6 they added is only nailed to the 2×4 and not to the bracing.  In essence, it’s just adding more load to the 2×4 purlins.  Not only that, some on the purlins do not even have any bracing support.
