Rainscreens: a definitive checklist?
Is there a definitive, authoritative checklist one can use to determine if a rainscreen is needed?
Nobody uses rainscreens in fiber cement siding houses where I live. I’m in mixed-humid Climate Zone 4. My area gets 55-60” of rain a year. Half of that rain can come in just 3 months. My area is humid and often wet…. like “I’m sick of this rain, where is the sun” wet.
Assuming roof overhangs are pretty standard, how necessary is a rainscreen? Yes, I know it can be a “good idea”, but is it enough of a good idea to insist on one?
Also, having a large front porch that will protect a large section of siding from 99% of typical rain, is it possible to do a rainscreen on more exposed walls, then turn the corner into the porch and skip the rain screen?
