Clapboard siding is one of the most recognizable and historically popular forms of home siding in North America, distinguished by its long, narrow planks installed horizontally in an overlapping pattern. This classic exterior not only provides a beautiful, familiar aesthetic but also offers superior weather protection for a clapboard house when properly installed.
The design relies on simple physics: each wedge shaped board laps over the board beneath it, creating an angle that effectively directs or sheds water away from the wall structure. For homeowners looking at siding options, understanding what is clapboard siding? remains the essential first step toward choosing a durable and beautiful finish for their house.
Understanding Clapboard Siding
To define clapboard siding, you must look at its shape and its function. Historically known as lap siding or weatherboard, clapboard refers to the horizontal installation method where the top edge of one board overlaps the bottom edge of the board above it.
The unique look of a clapboard house comes from the subtle shadow lines created by this overlap. When the sun hits the wall, the thickness of the bottom edge casts a shadow, which adds texture and depth to the entire facade.
The Origins of Wood Clapboard
The technique of splitting and tapering boards originated in New England, where its design was crucial for defending homes against harsh coastal weather. The name itself is thought to come from the Dutch word “klappen,” meaning “to split,” referencing the original process of splitting wood clapboard into thin, tapered strips.
Traditional materials were often wood clapboard siding made from naturally decay-resistant woods like cedar siding or pine. While traditional clapboard siding remains a popular choice for its authentic aesthetic, modern clapboards are now made from a variety of durable materials.
Types of Clapboard Siding Styles
Wood Clapboard Siding
Wood clapboard remains the gold standard for authentic appearance. Cedar siding is the most common choice because it naturally resists rot and insects. Traditional wood offers rich texture and can be painted or stained in any color you choose.
Real wood requires regular maintenance. You’ll need to repaint or restain every 5-7 years depending on your climate. However, many homeowners find the authentic look worth the extra effort. Wood clapboard typically costs between $6-12 per square foot installed.
Vinyl Clapboard Siding
Vinyl clapboard has become extremely popular for good reason. This durable material mimics the look of traditional clapboard siding without the maintenance headaches. Modern vinyl products feature realistic wood grain textures and come in dozens of colors.
The biggest advantage is minimal upkeep. Vinyl never needs painting and cleans easily with soap and water. It costs less than wood at $3-8 per square foot installed. While it won’t last quite as long as fiber cement, quality vinyl can serve your home well for 20-30 years with proper installation.
Fiber Cement Siding
Fiber cement represents the best of both worlds. This durable material looks like wood but stands up to weather better than any other option. Made from cement, sand, and cellulose fibers, it resists fire, termites, and rot.
Fiber cement clapboard offers excellent weather resistance and can last 50 years or more. It holds paint exceptionally well, often going 15 years between repainting. The main downside is higher initial cost at $8-15 per square foot installed. Professional installation is essential because the material is heavy and requires special cutting tools.
Engineered Wood Clapboard
Engineered wood combines wood fibers with resins and waxes for better moisture resistance than solid wood. These products look nearly identical to traditional wood clapboard but resist swelling and rot more effectively.
This option typically costs $5-9 per square foot installed. It needs painting like real wood but may go longer between maintenance cycles. High quality engineered products carry warranties of 25-50 years when properly maintained.
What are Clapboards Made Of? A Material Breakdown
The durable material used for your clapboard siding dramatically affects the cost, maintenance, and lifespan of your exterior. The search query “what are clapboards” often leads to a comparison of modern options.
Material | Initial Cost (Installed per sq. ft.) | Lifespan | Maintenance Needs | Key Benefit |
Wood Clapboard | $5 – $15 | 20 – 40 years | High (Requires scraping, painting/staining) | Authentic, natural look and feel. |
Vinyl Clapboard | $3 – $10 | 20 – 40 years | Low (Requires only periodic cleaning) | Most affordable and easiest to install. |
Fiber Cement Siding | $6 – $14 | 50+ years | Low-Medium (Repainting every 10-15 years) | Superior durability, fire, and pest weather resistance. |
Modern Clapboards: Fiber Cement and Vinyl
For modern homeowners, the choice usually comes down to vinyl clapboard or fiber cement siding:
- Vinyl Siding: This is the most budget-friendly option. It offers excellent weather resistance against moisture and does not require painting. However, it can fade over time and may crack in extreme cold or upon heavy impact.
- Fiber Cement: Products like James Hardie offer high quality fiber cement clapboard. It is significantly heavier, more expensive to install, but boasts superior durability, is fire-resistant, and can closely mimic the look and texture of real wood clapboard. This material provides the greatest long-term value.
Clapboard Siding Pros and Cons
Choosing the right material means weighing the benefits against the drawbacks. Your decision will depend on the material you select.
Advantages (Pros)
- Time-Tested Design: The horizontal, overlapping installation is proven to shed water effectively and protect the wall structure.
- Versatility and Curb Appeal: Clapboard offers a classic, clean look that suits almost every architectural style, adding immediate curb appeal.
- Variety of Materials: You are not limited to traditional wood; you can achieve the same look with low-maintenance, durable material options like vinyl and fiber cement.
- Clear Aesthetic: The clear shadow lines add dimension to the home siding, preventing a flat or dull appearance.
Disadvantages (Cons)
- Gaps for Pests: The overlapping design can create tiny gaps. These small spaces can be appealing to insects or collect dust and debris, requiring regular cleaning.
- Maintenance of Wood: If you choose wood clapboard, you must commit to a schedule of painting or staining every few years to prevent rot, warping, and water damage.
- Installation Difficulty: While the process is straightforward, achieving a perfectly level, uniform run of boards requires precision, especially with the heavy weight of fiber cement siding. Professional installation is recommended.
Installation and Maintenance Basics
Regardless of the siding options you choose, the basic installation of clapboard remains the same: the planks are installed horizontally from the bottom of the wall upwards. Each plank must be perfectly level to ensure a consistent look and proper water drainage. The overlap must be sufficient to allow for expansion and contraction, especially with wood clapboard.
For modern clapboards, maintenance is simple: periodic power washing with low pressure is often enough to keep the surface clean. For traditional clapboard siding, annual inspections for loose paint, cracks, or rot are necessary to preserve the life of the wood clapboard.

Frequently Asked Questions
Is clapboard siding a good choice for a house?
Yes. Clapboard is an excellent home siding choice due to its proven weather resistance and classic aesthetic. Its simple, overlapping design is a popular choice globally.
What is the difference between clapboard and shiplap?
Clapboard is characterized by its tapered, wedge shaped boards that overlap to shed water. Shiplap consists of boards with a distinct rabbet (or groove) cut into the edges so the boards fit together tightly, creating a flush or slight gap but not a tapered overlap.
Is clapboard more expensive than other siding options?
The cost of clapboard siding varies. Vinyl clapboard is one of the most affordable materials. Wood clapboard is mid-range, and fiber cement siding is often slightly more expensive initially but offers a better long-term return on investment due to its durability.
