The benefits of a front door overhang are protecting doors and windows, protecting building foundation, providing shade and keeping rain away from siding. A porch overhang keeps door knobs from freezing in the winter, and an all-around overhang protects an entire building structure.
Properly angled overhangs keep weather elements, such as rain and snow, away from doors and windows, providing lower energy and heating costs. Moisture from rain is kept away from building foundations with overhangs, saving the foundation from crumbling or being exposed to potential mold. Porch overhangs and awnings provide shade in the summertime, keeping buildings from overheating and creating comfortable spaces for leisure or guests.
