Giải thích
Manufacturers and the code call for clearance at the bottom of fiber-cement (and most) siding, commonly about 6 inches to earth and roughly 1 to 2 inches above roof surfaces, to keep the siding out of standing water and splash that would wick moisture. No clearance, 12 inches above a roof, or burying the siding are incorrect.
