Wondering what in the world lap siding is? It is actually an extremely popular siding option.

What is lap siding?

Lap siding is a flat siding composed of long boards that overlap each other, hence “lap” siding. This design is often called clapboard, even though lap siding has larger boards than clapboard siding.

You’ve probably seen this style of siding on a lot of new homes and remodeled exteriors due to it’s clean and charming appearance. Lap siding does a fantastic job highlighting stucco, stone, and brick on a home.

Lap siding options

Lap siding was commonly wood siding, but nowadays there are more lap siding styles available including fiber cement, engineered wood, and vinyl siding. Lap siding can be easy to repair because you only need to remove the damaged plank (unless moisture has crept in and the siding is compromised). LP® Smartside® and Hardie Board® are popular lap siding providers. LP® lap siding offers engineered wood and James Hardie® offers fiber cement siding options.

Lap Siding Installation

When lap siding is installed the smaller top part of the board is wedged under the piece above it. The wedging causes pieces to overlap and form a protective barrier around your house while creating a tidy appearance.
