Lap Siding: What Every PA Homeowner Should Know

Lap siding (also called clapboard or horizontal siding) is the most popular siding style in America. Each board overlaps the one below by about 1.25 inches, creating a shadow line that adds depth and dimension to the facade. Available in vinyl, fiber cement (James Hardie), wood, and engineered wood. The overlap design naturally sheds water downward. Lap siding is the classic choice for colonial, craftsman, and contemporary PA homes. Board widths range from 4" to 8"—wider boards create a more modern look, narrower boards suit traditional styles.

Understanding lap siding is important for homeowners in the Poconos and Lehigh Valley because Pennsylvania's climate puts unique demands on your home's exterior. With heavy snowfall, ice storms, and 80-120+ freeze-thaw cycles annually, the quality of your siding directly impacts your home's protection and your family's comfort.
