What Is Lap Siding?
Lap siding refers to a type of horizontal siding where long boards are installed to overlap one another, creating a tight seal that effectively sheds water. This design is both functional and decorative, and its popularity spans centuries from colonial times to contemporary homes.
Lap siding is a key option among the types of house siding that homeowners can choose from today.
Brief History and Usage
Lap siding traces its roots back to early American settlers, who used hand-sawn wood boards to protect their homes from the elements. Over time, its design evolved to incorporate more styles and materials, but the fundamental concept remains the same: staggered boards laid horizontally to form a durable and attractive cladding.
Where Is It Used?
- Residential homes (traditional and modern)
- Coastal and humid regions (e.g., the Southern U.S.)
- Renovation projects seeking historical accuracy
- New constructions looking for timeless curb appeal
This siding style not only improves insulation but also boosts resale value, making it a practical and aesthetic upgrade.
Types of Lap Siding
There are several variations of lap siding, each with unique visual and structural properties. Understanding the differences can help you match the style to your home’s architecture.
1. Clapboard (Traditional Lap Siding)
This is the most common form. Clapboard siding features boards that are thicker at the bottom than the top, creating a wedge shape that overlaps cleanly.
- Look: Classic and symmetrical
- Best for: Colonial, Cape Cod, and traditional homes
2. Dutch Lap
Dutch lap has a distinct groove at the top of each board, adding shadow lines that create more visual depth.
- Look: Slightly more decorative than clapboard
- Best for: Colonial Revival homes, mid-century homes
3. Shiplap
Shiplap boards feature rabbeted edges that allow them to fit together tightly, resulting in a flush surface.
- Look: Smooth, modern, seamless
- Best for: Farmhouse exteriors and interiors
4. Beaded Lap
This style includes a rounded bead at the bottom of each board for added ornamentation.
- Look: Decorative and refined
- Best for: Southern-style homes, Victorian facades
