What Is Clapboard Siding?

Clapboard siding, also referred to as lap siding or bevel siding, is a traditional exterior cladding style where long, narrow boards overlap horizontally. Each board is thicker on the bottom edge and thinner at the top, creating a subtle shadow line and effective water-shedding structure.

The term “clapboard” originates from the Dutch word klappen, meaning “to split,” reflecting the early method of splitting logs into uniform planks.

Modern clapboard siding has evolved to use durable materials like vinyl, fiber cement, and engineered wood, offering increased weather resistance, minimal maintenance, and greater design flexibility.

What Does Clapboard Siding Look Like?

Cedar wood is aesthetically pleasing, with a wide range of warm tones. Western Red Cedar tends to have a rich reddish-brown color, while Eastern Red Cedar features a dramatic contrast between purplish heart wood and creamy sapwood. Over time, cedar weathers to a beautiful silvery gray when left untreated, which adds to its rustic charm.

Aside from color, cedar is often praised for its aromatic qualities. The signature cedar scent is not just pleasant — it also acts as a natural insect repellent, which is why cedar is often used in closets and storage chests.

Types of Clapboard Siding

Clapboard siding comes in three distinct styles: traditional lap, Dutch lap, and beaded seam. Each style can be made from various materials and offers different aesthetic options.

Benefits of Clapboard Siding

  • Classic Aesthetic Appeal: Clapboard siding gives homes a warm, timeless look that fits both traditional and modern architectural styles.
  • Natural Insulation: Wood provides thermal insulation, helping to regulate interior temperatures.
  • Customizable Finishes: Can be painted or stained to match any design palette.
  • Repairability: Individual boards can be replaced without disturbing the entire wall.
  • Durability: Especially when using resilient woods like cedar or redwood, clapboard siding can last decades with proper care.

Where Is Clapboard Siding Used?

Clapboard siding originated in the Northeastern United States and remains especially popular in New England. Its timeless aesthetic and broad design appeal have helped it spread across the country, making it a common choice in both historic and modern architecture.

Clapboard siding is used on a variety of structures including houses, barns, garages, and specialty buildings. Its versatility makes it suitable for full facades or as an accent feature on dormers, gables, or entryways. Whether covering an entire exterior or adding visual contrast to specific elements, clapboard offers a classic look that blends well with many architectural styles.

What Is Clapboard Siding Made Of?

Traditionally, clapboard siding was crafted from raw timber such as pine, cedar, or oak. While wood clapboard has a beautiful, natural appearance, it also presents challenges. It is vulnerable to moisture damage, dry rot, and insect infestations. In addition, maintaining wood siding requires regular sealing, painting, and repairs. Sustainable sourcing of hardwoods can also be difficult to verify, which limits its practicality for modern builders.

What Is Modern Clapboard Siding Made From?

To preserve the authentic appearance of clapboard while improving durability and maintenance, manufacturers have introduced alternative materials. Today, clapboard siding is commonly made from vinyl, metal, and fiber cement. Among these options, fiber cement is considered the best balance of aesthetics, strength, and weather resistance. It mimics the texture of wood but resists rot, insects, and moisture—making it an ideal choice for long-term performance with minimal upkeep.

Is It Easy to Repair Clapboard Siding?

Repairing clapboard siding depends largely on the material. Fiber cement siding generally requires very little maintenance and is highly durable, so repairs are rarely needed. In contrast, wood siding demands a higher level of care. Repairing wood clapboard often involves custom cutting and precise installation to maintain a seamless look, which can be labor-intensive and costly.

Vinyl clapboard, while easier to replace in sections, presents a different challenge. Over time, vinyl fades due to sun exposure, making it difficult to match replacement pieces to existing panels. As a result, patch repairs may be visible and reduce the home’s curb appeal. This is one reason why many homeowners now prefer fiber cement as a long-term, low-maintenance solution.

Clapboard Siding Pros and Cons

Below are the Clapboard Siding Pros and Cons:

Pros:

  • Water Resistance: The angled bevel installation makes clapboard siding highly water-resistant, providing excellent protection against rain and snow, making it ideal for wet climates.
  • Customization: Clapboard siding is highly customizable, offering various materials, board sizes, and overhang styles, allowing homeowners to achieve a unique exterior look.
  • DIY-Friendly: Its relatively straightforward installation process makes it accessible for DIY projects.

Cons:

  • Gaps: Clapboard siding can create gaps that collect dust, requiring regular cleaning.
  • Pest Attraction: These gaps can also attract insects, potentially leading to infestations.

How to Install Clapboard Siding

Clapboard siding should be installed starting at the bottom of the wall and working upward. Here are key installation notes:

  • Sheathing & Moisture Barrier: Install rigid sheathing and a house wrap to protect against moisture intrusion.
  • Starter Strip: Begin with a starter strip to provide a proper angle for the first board.
  • Fasteners: Use corrosion-resistant nails (like stainless steel or galvanized) placed just above the overlap.
  • Expansion Gaps: Leave small gaps between boards for seasonal expansion.
  • Flashing: Proper flashing around windows, doors, and trim is essential for weatherproofing.

The Cost of Using Clapboard Siding

Clapboard siding is a cost-effective wood siding option, known for its straightforward installation and availability in various materials. Material costs range from $1 to $12 per square foot, with labor costs adding an additional $1 to $3 per square foot when hiring a local siding contractor.

If opting for wood, the price varies by type:

  • Pine: $1 to $5 per square foot, the most affordable option.
  • Redwood: $4 to $20 per square foot, depending on location.
  • Western Red Cedar: $3 to $4.50 per square foot, widely available.

Proper maintenance is crucial to extend the lifespan of your clapboard siding. Annual inspections help identify and address any issues, keeping the siding clean and in good condition. If using cedar, be aware that its maintenance needs may differ due to its softwood nature.

Frequently Asked Questions Of Clapboard Siding

Below are some questions related to clapboard:

What is Siding Clapboard?

Clapboard siding, also known as bevel siding or lap siding, is a popular horizontal wood siding profile. The boards are beveled, meaning they are thinner at the top and thicker at the bottom, allowing them to overlap when installed. This overlapping design creates an effective weather barrier, making clapboard siding a durable choice that has been used for centuries, even in harsh coastal environments.

Is clapboard siding good? 

Yes, clapboard siding is a great option for many homeowners. It offers timeless beauty, versatility, and a variety of colors and textures, making it an excellent investment. One of the key advantages of clapboard vinyl siding is its durability and longevity, ensuring that it not only enhances the aesthetic appeal of your home but also provides lasting value and satisfaction.

What is the difference between a clapboard and a weatherboard? 

The primary difference between clapboard and weatherboard lies in their material and how they are produced. Clapboard is typically made from hardwoods like oak or pine and is created by splitting thick wooden boards into thin strips. In contrast, weatherboards are usually made from softwoods such as yellow pine or poplar and are sawn rather than split. Additionally, weatherboards are typically wider and longer, being about eight inches wide and ten to twenty feet in length, and are tapered in section similar to clapboard to allow for overlapping installation.
