Does anyone have any clear understanding on when and how many downspouts should be used? Is there a rule, like if a gutter is under 3' long then only 1 downspout is required vs. needing 2 (1 on either end of the gutter)?
Also if we have a situation where the gutters meet at the corner, does NCARB read the 2 separate gutters as 1 and therefore only 1 downspout is required as shown in the image below?
