05 Feb Champia Inspector Atlanta Finds Home’s Rafters Get Little Support
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.
- Purlins shall be sized no less than the required size of the rafters that they support.
- Purlins shall be continuous and shall be supported by 2×4 braces installed to bearing walls at a slope not less than 45 degrees from the horizontal.
- The braces shall be spaced not more than 4 feet on center and the unbraced length of braces shall not exceed 8 feet.
