How much weight can a 2x8 support?

A 2×8 will adequately support a dead load of 20 psf and a live load of 40 psf depending on some factors, including allowable span. This equates to a total load of 60 psf. Therefore, for a 2x8x10, the total load would equal 600 pounds per lineal foot.

Why do roofers use nails instead of screws?
