Summary:
- Lap board siding is horizontal boards that overlap, so each one sheds water onto the board below.
- The overlap is the point: it directs water away from the wall, which is why the profile has lasted centuries.
- Styles include traditional clapboard, Dutch lap, and beaded lap, each with a different shadow line.
- James Hardie lap siding carries a 30-year non-prorated warranty, and ColorPlus® finishes carry a separate 15-year finish warranty.
- GS Exterior Experts installs lap siding across the Denver metro, including the flashing and trim details that decide whether it performs.
Colorado homeowners have many options for exterior siding, but few offer the time-tested durability and curb appeal of lap board siding. Known for its clean lines and weather-resistant design, lap siding has remained a go-to choice for homeowners who want a traditional look without compromising performance. At GS Exterior Experts, we install lap board siding that’s built to handle Colorado’s freeze-thaw cycles, hailstorms, and intense sun.
Whether upgrading from stucco, vinyl, or aging wood, lap siding offers versatility and strength. Let’s take a closer look at the benefits, styles, and why lap board siding continues to be a favorite in our region.
What Is Lap Board Siding?
One of the most classic and enduring exterior designs is lap board siding, a key category within the broader group of horizontal siding types. Lapboard siding features a beautiful arrangement of horizontal boards, each gracefully overlapping the board beneath it. This design looks good and provides strong protection for your home, making it a popular choice for people who want to improve their exterior.
How It Works
The overlapping design helps channel water away from your home, making it especially effective in areas with rain, snow, and wind. It’s a style that dates back centuries, yet it continues to evolve with modern materials like fiber cement and engineered wood.
Materials and Options
Lap siding comes in several materials, and the profile looks similar across all of them:
- Fiber cement, non-combustible, 30-year warranty
- Engineered wood, lighter and faster to install, though combustible
- Natural wood, the real thing, with a re-staining cycle
- Vinyl, lowest cost, fades at altitude and brittle in cold
Each material offers a slightly different look and performance profile. While many modern materials offer the classic aesthetic of horizontal siding, their performance profiles vary significantly. This is especially true when considering the different types of wood siding in Colorado and their suitability for the local climate.
Benefits of Lap Board Siding for Colorado Homes
Lap siding isn’t just about looks. It offers real functional advantages that hold up well in Colorado’s climate.
1. Strong Weather Resistance
The overlapping boards act as a shield against water and wind intrusion. When installed properly, they prevent moisture from seeping behind the siding, a key factor in preventing mold and rot.
2. Classic Curb Appeal
Lapboard siding creates strong horizontal lines that make your home look larger, more structured, and timeless. It works well with various architectural styles, from traditional ranch homes to modern farmhouses.
3. Low Maintenance (With the Right Material)
Fiber cement lap siding, like James Hardie, requires little maintenance beyond occasional washing. It won’t warp, peel, or attract pests like natural wood can.
4. Fire and Pest Resistance
Fiber cement is classified as non-combustible under ASTM E136, which matters in Colorado’s wildland-urban interface, where the code can require it. Termites won’t eat it, and woodpeckers can’t get through it.
When installed by experts, lap board siding provides high performance and peace of mind, even during Colorado’s harshest seasons.
Popular Styles of Lap Board Siding
Lap board siding comes in several substyles, each offering a different visual profile to match your home’s architecture.
- Traditional Lap – Also called “clapboard,” this is the most common type of lap siding. It features evenly overlapped boards with a smooth or woodgrain texture.
- Dutch Lap – This version has a notch at the top edge of each board, creating a deeper shadow line and a more sculpted appearance.
- Beaded Lap – Featuring a rounded bead at the bottom edge of each board, this style adds a subtle decorative element. This delightful design element elevates the aesthetic and perfectly complements classic or colonial-style homes, infusing them with timeless elegance.
- Shiplap (vs. Lap) – Although often confused, shiplap is installed with boards that sit flush rather than overlapping. Due to its lower moisture resistance, it’s more common for interior design than exterior use.
You can achieve different design effects with lap siding by choosing the right profile and finish for your home’s style. However, the distinction goes beyond aesthetics when comparing Dutch Lap vs traditional siding. While both are classic horizontal styles, they offer different visual impacts and can even have slight differences in installation.
Why Homeowners Choose Lap Board Siding Over Alternatives
Lap siding competes with stucco, vertical panels, and shingles, and it wins on versatility more than on performance, since the same material is available in all of those profiles.
Greater Versatility
Lap board siding works well with other siding materials, allowing for mixed-material exteriors. For example, it can be combined with board and batten or stone veneer accents.
Cost-Effective Over Time
Fiber cement costs more than vinyl upfront and lasts considerably longer, and with a factory finish, there is no repaint cycle. Whether that works out cheaper depends on how long you stay, which is worth being honest about.
Customization Options
Homeowners can personalize lap siding with various choices, including:
- Board width
- Surface texture (smooth, cedar, woodgrain)
- Paint or pre-finished color options
- Trim accents for windows, doors, and corners
Lap board siding strikes a balance between durability, customization, and resale value, making it one of Colorado’s most popular exterior upgrades.
