Trying to decide between shiplap and clapboard siding? It’s a common design dilemma, especially when both look good in photos but serve different purposes. Maybe you’re updating your home’s exterior or adding some personality to your interior walls. Either way, the choice can feel confusing if you’re not sure how they actually differ beyond just looks.
In this blog, we’ll go over everything you need to know. What each siding style is, how they’re used, what they look like, and which one might suit your home better.
What is Shiplap?
Shiplap is a type of wooden board that fits together using a groove called a rabbet. When installed, these boards overlap slightly at the edges, leaving a small, consistent gap between each one. This gap gives shiplap its signature lined look. It’s simple, clean, and brings a sense of order to any space.
Although shiplap was originally used to waterproof the sides of barns and older homes, it has recently gained popularity in modern home interiors. People now use it on living room walls, bedroom ceilings, and even kitchen backsplashes to create a cozy, farmhouse-inspired vibe. It’s also flexible in style—you can paint it white for a minimalist look, go bold with dark shades, or leave the wood natural for a more rustic finish.
While shiplap can be used outside, it needs to be properly treated and sealed to handle moisture and weather changes. Indoors, it’s a decorative feature that’s as much about texture as it is about design.
What is Clapboard?
Clapboard, also known as lap siding, is one of the oldest and most common types of exterior siding in the U.S. Instead of fitting together with a groove, clapboard boards are laid flat and overlap one another from top to bottom. This overlapping design helps water run off naturally, which is one reason why clapboard has been used on homes for hundreds of years.
Clapboard gives off a more traditional and layered look compared to shiplap. It creates shadows between the boards because of how they’re stacked, which adds dimension and character to the outside of a house. It’s especially common in colonial-style or Cape Cod homes, though it works well with any classic or coastal design.
Unlike shiplap, clapboard is usually meant for outdoor use. It’s available in many materials now, including wood, vinyl, fiber cement, and engineered wood—each offering different levels of durability and upkeep.
The Visual Differences
While both styles use horizontal boards, they give off very different visual vibes. Shiplap has a smoother, more modern appearance. The evenly spaced lines between boards give walls a neat, polished finish. It’s especially popular in interiors because it blends well with both traditional and modern design.
Clapboard, on the other hand, has more texture. Because the boards overlap, they create a natural shadow line that adds depth to a home’s exterior. It’s not as smooth-looking as shiplap, but that’s part of its charm. It has an aged, sturdy look that many homeowners love for its timeless appeal.
So, if you’re going for a more sleek and clean look—especially inside your home—shiplap is the winner. But if you want an exterior that feels strong, textured, and rooted in tradition, clapboard is the better pick.
Installation & Durability
Installing shiplap indoors is generally easier than working with clapboard siding. The boards are often pre-cut and can be nailed directly onto drywall or wall studs. It’s a great project for DIYers or anyone looking to update their walls without taking on a huge renovation. Just keep in mind that gaps between the boards can collect dust, especially if you’re using it inside.
For outdoor projects, shiplap takes a bit more effort. It must be sealed properly, especially in wet or humid climates, to prevent warping or mold growth.
Clapboard is more demanding to install, especially if it’s made from wood. Since the boards are layered, each one must be carefully lined up and nailed to create an even surface. While that takes more time, it also adds durability. The overlapping design helps water slide off easily, which is why clapboard is such a reliable siding choice for outdoor use.
When it comes to long-term performance, clapboard (especially when made from fiber cement or vinyl) generally holds up better outdoors. It’s designed to face the elements, whereas shiplap—unless well treated—is best suited for indoor use.
Best Uses for Each
Shiplap shines when used indoors. It works beautifully in living rooms, bedrooms, hallways, and even bathrooms. It’s also a nice touch on ceilings or behind open shelving. If you’re trying to give your home a warm, farmhouse-style look, shiplap is an easy way to do it.
Clapboard is ideal for house exteriors. It adds curb appeal and helps protect your home from rain, snow, and wind. It works on just about any type of house—from small cottages to larger traditional homes. It’s especially well-suited for areas with varying weather conditions because of how it handles moisture.
Shiplap vs Clapboard Siding: Pros and Cons
Shiplap is great for style and ease of installation. It gives walls a lot of personality without feeling too heavy or detailed. But if not sealed properly, it can absorb moisture and warp over time, especially outdoors.
Clapboard, on the other hand, is better for durability and outdoor use. Its overlapping design gives it a functional edge. It’s not often used indoors because of its heavier, more rugged look, but outdoors it holds up extremely well and gives homes that classic, timeless feel.
Cost Overview
Both options can vary in price depending on material and location. In general, shiplap tends to cost a little less if you’re using it for a small interior space. The boards are thinner and lighter, and if you’re installing it yourself, you can save even more on labor.
Clapboard may cost more upfront, especially if you choose natural wood or fiber cement. However, it often lasts longer outdoors, so you may end up saving money on repairs or replacements in the long run.
For reference:
- Shiplap (wood): Around $2–$7 per square foot for materials
- Clapboard (wood): Around $3–$8 per square foot
- Clapboard (fiber cement): $2–$6 per square foot
Keep in mind, these are just rough estimates and can change depending on local suppliers and the size of your project.
Which Should You Pick?
Choosing between shiplap and clapboard depends on two things: where you’re using it and what kind of look you want. If your goal is to update the inside of your home with something clean, stylish, and easy to work with, shiplap is probably the way to go. It’s beginner-friendly and works in nearly any room.
But if you’re focusing on the outside of your house, clapboard is the better fit. It’s made for weather resistance, offers more texture, and gives your home a charming, traditional feel that lasts for decades.
Think about your climate too. In humid or wet areas, clapboard—especially in a material like vinyl or fiber cement—will hold up better over time. If you’re in a dry area or using it indoors, shiplap offers more design flexibility.
Final Thoughts
At the end of the day, both shiplap and clapboard siding bring something different to the table. One is about clean lines and cozy interiors, the other is about strength, protection, and classic curb appeal.
If you’re looking for an easy way to add style to your interior walls, shiplap can totally transform a room. If you’re building or renovating the outside of your home, clapboard will give you the performance and look that lasts.
Whichever you go with, make sure it matches your home’s style and meets your long-term needs. And remember—you can always mix and match. Some homes even feature clapboard outside and shiplap inside for the best of both worlds.
