Roof is covering small 11x13 outbuilding. Slope is 4:12. Using 2x8 ridge
board and 2x6 rafters.
No problems with the rafter trig - got that covered. No problem with the
span of the 2x6 rafters either. A mere 11 ft / 2 = 5.5 feet (roughly) - all
to code. Overkill, but I want an R-19 roof.
My question is this: I've looked at a bunch of codes, and I can't seem to
find anything that covers the span of the *ridgeboard*
, especially as it
applies to the roof slope. I'm certain the ridgeboard can not span as far
on a 4:12 as it could on a 6:12, for example.
I'm probably overkill like the rest of the roof, but I'd like to know for
100% certain. Snow and 100 mph wind load codes apply at this location.
I know a steeper roof would be more bomber, but I want to match the house.
