Normally you won't see 2x4s as rafters unless in small enclosures.
As you pointed out, your 2x4s may not fail for strength by code but
may or may not meet the code for deflection. Just for others benefit,
usually 2 criteria are involved in designing a structure.... strength
and deflection. They are independent of each other and specified by
I too own other houses but haven't noted any roof problems when I
owner financed them to others. None of them had 2x4's as rafters.
Now if it happens it's their worry <grin>.
It would only take a couple of minutes per post to do. I suppose that if
those few minutes of time were that precious then you could omit the bevels,
but I like doing the job right. I have some rental property that every
corner that could be cut was cut and fixing things there always is a
surprise taking more time than it should, so I tend not to cut corners,
especially if doing it right only takes a short amount of time more.
About the time I had mastered getting the toothpaste back in the tube, then
Chill, Rog...see that smiley? :)
But, depends on what is your perception of "right" to a certain degree
at least...in a really arid climate the amount of rainfall is so slight
the difference in lifetime over a slanted post top vis a vis a flat will
be indiscernible. Now, if it were an aesthetics question or in a damp
locale, I'd never have mentioned it...
But, it was, after all, only a jest, remember... :)
