Traditional wood shake siding looks great — until it doesn’t. Rot, splitting, warping, woodpecker damage, and constant repainting are problems every Western PA homeowner eventually faces with real cedar. HardieShingle siding was built to solve all of that. It gives you the same classic look without the ongoing headaches.
This guide covers everything you need to know: panel styles, specs, installation basics, cost, and warranty details — so you can make a confident decision before spending a dollar.
I’m Don Kovac, owner of Big River Roofing in Hermitage, Pennsylvania, and our crew has hands-on experience installing the hardie shake panel system across Mercer, Lawrence, Butler, and Beaver Counties. We’ll walk you through everything in plain language so you know exactly what you’re getting.
What is HardieShingle Siding?
HardieShingle siding is a premium fiber cement siding product manufactured by James Hardie: House Siding & Backer Board. It is specifically designed to replicate the warm, rustic aesthetic of natural cedar shake shingles. However, unlike wood, which absorbs moisture, decays, and burns easily, this material is composed of a high-density mixture of Portland cement, sand, cellulose fibers, and water.
When you choose a hardie shake panel, you are investing in a product engineered to survive the elements. It is formulated as noncombustible per ASTM E136, meaning it will not ignite when exposed to direct flame and won’t act as fuel for a house fire. Additionally, because fiber cement is completely inorganic, it holds absolutely no appeal for pests like termites and wood-boring woodpeckers, which frequently plague Western Pennsylvania homes.
To ensure long-term durability, James Hardie developed the Engineered for Climate® system. This system divides North America into distinct climate zones to customize the siding’s formulation:
- HZ5 Climate Zone: Formulated specifically for regions with freezing temperatures, seasonal snow, ice, and extreme temperature swings. If you live in Hermitage, Butler, Beaver, or anywhere else in Western PA, your home will use HZ5 products. This formulation resists damage from freezing and thawing cycles, ensuring the panels won’t crack or delaminate.
- HZ10 Climate Zone: Engineered for hot, humid, tropical climates. This variant is designed to withstand intense UV exposure, high humidity, and hurricane-force winds.
By tailoring the chemical makeup of the siding to the local climate, James Hardie ensures that your Hardie® Shingle Siding | James Hardie remains structurally sound for decades.
Choosing the Right Hardie Shake Panel Style
One of the greatest benefits of the hardie shake panel system is its design versatility. Whether you want to cover your entire home for a classic Cape Cod look or use shingles as an accent in your gables, there is a style to match your vision.
There are three primary styles of HardieShingle panels:
- Straight Edge Panels: These panels feature clean, uniform bottom edges. They offer a slightly more refined and contemporary look, making them excellent for modern craftsman homes or for softening highly contemporary architectural designs.
- Staggered Edge Panels: With varying shingle lengths and uneven bottom edges, staggered edge panels deliver a highly rustic, laid-back aesthetic. They are incredibly popular for cottage-style homes and as accent features on gables.
- Half-Round Decorative Shingles: These semi-circular shingles provide a timeless, historical look. They are most commonly used as decorative accents on historic renovations or within the upper peaks of gables to add architectural interest.
To help you decide which style fits your project, here is a quick comparison:
| Panel Style | Bottom Edge Aesthetic | Best Use Case | Standard Exposure | Pieces per Square (100 sq. ft.) |
|---|---|---|---|---|
| Straight Edge | Clean, uniform, straight | Full wrap, modern craftsman, clean transitions | 7 inches | Approx. 43 pieces |
| Staggered Edge | Alternating lengths, rustic | Accent walls, gables, rustic cottage look | 6 inches | Approx. 50 pieces |
| Half-Round | Semi-circular, historic | Decorative accents, gable peaks, Victorian styles | 7 inches | Approx. 43 pieces |
Sizing and Specifications of the Hardie Shake Panel
To plan your siding project accurately, you need to understand the physical dimensions and coverage requirements of these panels. HardieShingle panels are manufactured with a nominal thickness of 1/4 inch (0.25 inches). Each standard panel measures 48 inches in length by 15.25 inches in height.
However, because the panels overlap during installation to keep water out, the “exposure” (the visible portion of the shingle once installed) is smaller than the actual height:
- Straight Edge and Half-Round Panels: Installed at a maximum 7-inch exposure. At this exposure, each panel covers approximately 2.33 square feet of wall space. This means you will need approximately 43 pieces to cover one square (100 square feet) of wall.
- Staggered Edge Panels: Installed at a maximum 6-inch exposure. Because of the deeper overlap required for the staggered look, each panel covers 2 square feet of wall space. You will need exactly 50 pieces to cover one square (100 square feet).
ColorPlus Technology and Prefinished Options
When purchasing your hardie shake panel siding, you have two main finishing options: primed-only or prefinished with ColorPlus® Technology.
If you choose primed panels, they arrive ready for your contractor to apply high-quality exterior acrylic latex paint on-site. This is a great route if you have a highly specific, custom paint color in mind.
However, we highly recommend choosing prefinished panels with ColorPlus Technology. This proprietary process involves applying multiple coats of paint in a factory-controlled environment and baking it on. This creates an incredibly strong bond that resists chipping, peeling, and cracking.
The benefits of prefinished ColorPlus panels include:
- UV Resistance: The baked-on finish is highly resistant to fading from ultraviolet rays, keeping your home looking freshly painted for years.
- Color Consistency: Because the paint is applied by machines in a factory, there are no brush marks, lap lines, or variations in thickness.
- Weather Immunity: On-site painting requires dry, mild weather. ColorPlus panels can be installed year-round—even during chilly Western PA winters—without waiting for a painting window.
- Natural Cedar Stains: For those who want the look of real wood, James Hardie offers prefinished panels in beautiful, multi-toned natural cedar stains that carry a 15-year limited finish warranty.

Installation Guide for HardieShingle Siding
Proper installation is the single most important factor in how your siding performs over time. Fiber cement is heavy, rigid, and requires specialized tools and techniques. If installed incorrectly, you risk voiding the manufacturer’s warranty and allowing moisture to penetrate your home’s structural framing.
At Big River Roofing, we follow the manufacturer’s strict guidelines to ensure a flawless install. If you are looking to update your home’s exterior, we encourage you to read more about our professional Siding services.
How to Install a Hardie Shake Panel System
Here is a high-level overview of how a professional crew installs a hardie shake panel system:
- Prep the Substrate: A high-quality, code-compliant water-resistive barrier (house wrap) must be installed over the sheathing. All windows and doors must be properly flashed.
- Install the Starter Strip and Course: Before the first shingle panel goes up, a 1-1/4 inch starter strip is installed along the bottom edge of the wall. Over this, an 8-1/4 inch piece of HardiePlank lap siding is installed as a starter course to kick the first row of shingles out at the correct angle.
- Establish Chalk Lines: We snap a level chalk line exactly 8-1/4 inches up from the bottom edge of the starter strip to align the first course of panels.
- Fastening Requirements: Fasteners must be corrosion-resistant or stainless steel siding nails (often ring-shank nails for superior holding power). Nails must be driven into the wall studs, which can be spaced up to 24 inches on center. If nailing into sheathing alone, nail spacing must not exceed 13-3/4 inches on center.
- Nail Placement: Nails must be placed 1/2 inch to 1 inch from the side edges of the panels and 8-1/2 inches to 9 inches up from the bottom edge. Nails must be kept at least 3/8 inch away from any shingle edge.
- Staggering and Keyway Spacing: To prevent water from tracking behind the siding, panels must be staggered so that the vertical gaps (keyways) between shingles do not align on successive courses.
- Trim Clearances: A 1/8-inch gap must be left between the siding panels and any trim boards (such as window casings or corner posts) to allow room for a high-quality sealant joint.
- Gable and Roof Clearances: Siding must maintain a minimum 2-inch clearance from roof lines, decks, and paths to prevent water from wicking into the bottom edges of the panels.
Frequently Asked Questions About HardieShingle
What is the difference between HardieShingle and traditional cedar shake?
While traditional cedar shake offers undeniable natural beauty, it requires an immense amount of maintenance. Wood naturally absorbs moisture, which leads to rotting, warping, splitting, and paint failure. Wood shingles must be washed, stained, or painted every few years to prevent decay. Furthermore, wood is highly combustible and vulnerable to woodpeckers, carpenter bees, and termites.
HardieShingle panels deliver the exact same texture and shadow lines of cedar shake but are completely resistant to rot, warping, and pests. They are noncombustible and require only occasional washing with a garden hose and soft brush to look pristine.
How much does HardieShingle siding cost and where can I buy it?
The material cost for HardieShingle panels is higher than standard vinyl siding, but it is highly competitive with real wood cedar shakes. Because of the weight and packaging requirements, these panels are typically sold in pallet quantities. For example, a standard pallet might contain 100 panels (covering roughly 200 square feet of wall space).
For pricing reference, you can look at regional suppliers like Shop James Hardie Sidings at Dunn Lumber Co. | HardieShingle Panel Staggered . However, for local delivery and professional installation in the Greater Pittsburgh and Western PA area, homeowners typically source materials through local building supply yards like James Hardie Siding in Pittsburgh | Allegheny Millwork & Lumber or major home improvement centers like Lowe’s.
What is the warranty on HardieShingle panels?
James Hardie stands behind its products with some of the strongest warranties in the building materials industry. HardieShingle siding panels carry a 30-year non-prorated limited transferable substrate warranty.
“Non-prorated” means the value of the warranty does not decrease over time; if a manufacturing defect is found in year 25, you receive the same coverage as you would in year 5. “Transferable” means that if you sell your home, the warranty transfers to the next owner, which adds immediate resale value to your property. If you choose ColorPlus prefinished panels, the baked-on finish is also backed by a 15-year limited warranty against peeling, cracking, and chipping.
