Polymer shake siding delivers the look of hand-split cedar without the upkeep. Manufacturers have refined the material for more than four decades, and the category keeps changing: new profiles, expanded color systems, and distribution programs that put product in front of installers faster. One of the oldest polymer shake lines was recently renamed, and the rebrand came with a dealer express program that keeps every profile, color, and accessory in stock and ships orders within 48 hours. Speed matters on siding jobs because crews work against weather windows, and manufacturers that strengthen dealer networks with stocking commitments take the guesswork out of the lumberyard counter.
What Polymer Shake Siding Is
Polymer shakes are molded panels that replicate the texture and profile of painted cedar shingles. The material is an engineered polymer formed under heat and pressure, and it is impervious to moisture, resistant to severe weather, and stable from ground contact up to the roofline. Because the product does not absorb water, it avoids the cupping, splitting, and surface growth that wood shakes develop over time.
Independent ratings and standards programs give contractors comparable data before they commit to a product. The window shade efficiency ratings used in the AERC program are one example of how the industry standardizes performance claims, and shake manufacturers publish equivalent documentation on moisture absorption, impact resistance, and wind performance in their spec sheets.
The category began more than 40 years ago when molders figured out how to press polymer into panels that carried the grain and split lines of real cedar. Modern lines are still built from molds taken from actual hand-split shakes, so the texture is captured at the source. The result reads as wood and holds that appearance through decades of sun, rain, and freeze-thaw cycles.
How Polymer Shakes Compare with Cedar
The comparison starts with the raw material. Cedar is a renewable resource with natural rot resistance, but it requires periodic staining or sealing and it weathers unevenly across a wall. Polymer shakes cost more at the counter and return the difference in reduced maintenance and longer intervals between refinishing. Cedar also varies by grade and source, while polymer panels are consistent from box to box.
| Property | Cedar shakes | Polymer shakes |
|---|---|---|
| Moisture | Absorbs water, can split | Impervious to moisture |
| Maintenance | Staining and sealing cycles | Low maintenance |
| Color | Fades to gray | Solid and variegated options |
| Service life drivers | Weathering, insects | UV and impact resistance |
Where Polymer Shakes Fit on the Building Envelope
The material works on exterior walls, gable ends, dormers, and roof accents. Because it is impervious to moisture, it suits ground-contact zones where splash and snowmelt collect, and it holds up at the roofline where wind-driven rain is constant. Installers also use it on porch ceilings, chimney chases, and other spots where wood would need frequent attention.
Ventilation is still required behind any shake wall. Polymer panels are installed over a drainage plane or furring strips so moisture that gets past the siding can escape, and the manufacturer’s installation instructions spell out the minimum air gap and fastener schedule for each profile.
How Shake Products Reach the Job Site
Siding products move through a distribution chain with four links: the manufacturer, the distributor, the lumberyard, and the installer. The installer orders from a local lumberyard, the lumberyard places the order with a distributor, and the distributor triggers a direct shipment from the manufacturer back to the lumberyard. In a dealer express program, that shipment arrives within 24 to 48 hours because the manufacturer commits to carrying every profile, color, and accessory in stock.
Trade coverage of customer service programs that work points to the same three traits: reliable stock, fast turns, and clear communication between counter staff and installers. A dealer express program bundles all three into a single ordering process, which is why the model spreads through the industry.
The arrangement pays off at every stop in the chain. The installer gets a firm pickup date instead of a backorder notice. The lumberyard carries the line without tying up its own cash in slow-moving inventory. The distributor earns the order without warehousing every color, and the manufacturer ships full loads. Faster turnaround also cuts the time a crew spends waiting.
The Order Path from Installer to Job Site
- The installer confirms the profile, color, and square footage at the lumberyard counter.
- The lumberyard sends the order to its distributor.
- The distributor triggers a direct shipment from the manufacturer.
- The shipment arrives at the lumberyard within 24 to 48 hours.
- The crew picks up the material or takes a scheduled delivery.
What Always-in-Stock Shipping Means for Scheduling
An always-in-stock commitment lets a contractor start a job without waiting out a six-week lead time. That changes how crews bid work, because material availability is locked in before the first row of shakes goes up, and change orders for extra material arrive on the same short cycle.
For remodelers, the benefit shows up in weather delays. When a storm pushes a job back a week, the crew can reorder without losing the production slot, because the product is still on the shelf. Projects that would have stalled for a month now move within the same week.
Shake Profiles and Exposure Options
A profile is the shape and texture of the shake, and the exposure is the visible height of each row after the next course overlaps it. The two numbers together determine how the wall reads and how many rows the crew installs. Standard polymer shake lines offer exposures from 5 inches to 9 inches.
Roof and wall products carry documented quality programs that buyers can check before specifying. The asphalt roofing quality standards tracked in the QARC awards program show how the industry grades plant output, and polymer shake makers maintain comparable process standards across their profile lines.
- Hand Split profile: random grooves that capture the rustic character of hand-cut cedar, with a 7-inch exposure.
- Rustic Cedar 9 profile: deep grain texture with a 9-inch exposure for a bolder wall.
- RoughSawn Cedar Single and Dual profiles: long, subtle grain at a 6-1/2-inch exposure with evenly aligned shingles.
- Cape Cod Perfection profile: straight lines and natural cedar texture at a 5-inch exposure.
The profiles serve different elevations. A 5-inch exposure suits small cottages, dormers, and accent bands where a fine texture reads best. The 9-inch exposure covers large walls with fewer courses and a chunkier, more contemporary look. Matching exposure to building scale matters more than matching it to color.
RoughSawn Profiles for Dormers and Peaks
The RoughSawn Single profile is sized for dormers and peaks, where narrow runs would waste material. The Dual profile covers more wall area per panel, which speeds up large walls and reduces the number of seams on long elevations.
Coverage and Waste Planning
Exposure drives the coverage math. A wall with a 9-inch exposure needs fewer rows than one with a 5-inch exposure, and the crew cuts fewer pieces. Ordering 5 to 10 percent over the measured wall area covers gable cuts, openings, and starter courses without a second trip to the yard. Contractors who mix Single on the dormers and Dual on the main walls cut waste further, because each profile is used where its dimensions fit best.
Color Options and Pairing with Other Sidings
Polymer shakes come in solid colors and variegated blends that mimic the tonal variation of stained cedar. Variegated systems distribute several shades across the wall, which hides minor surface differences and gives the elevation depth under changing light.
Resilience planning has started to shape material choices at the community level. The EPA green infrastructure program helping five state capitals build more resilient communities treats durable, low-maintenance exteriors as part of the equation, and polymer shakes fit because they hold color and structure through storms without a repaint cycle.
Solid Versus Variegated Color Systems
Solid colors read as a flat, uniform wall. Variegated systems read as weathered wood. The choice is mostly aesthetic, but variegated blends are more forgiving on large elevations where lighting changes across the day, and they hide the slight color shift that occurs between production runs.
Pairing Shakes with Fiber Cement and Stucco
Shakes complement fiber cement, engineered vinyl, stucco, and brick. A common pattern uses shakes on the upper walls or gable ends and a contrasting material below, which breaks up the elevation and trims the total square footage of the premium product.
Accessories are part of the system. Color-matched corner boards, ridge caps, and trim pieces keep the installation looking finished, and ordering them with the siding avoids the two-tone mismatch that shows up when trim comes from a different production run. Most lines offer the same color list for accessories as for the panels themselves.
Labor, Lead Times, and Installation Planning
Siding installation is skilled work, and crews are scarce in most markets. The shortage shows up in bid prices and schedules, so contractors plan material and labor together rather than treating siding as an afterthought.
The construction worker shortage has pushed builders to consider every option for staffing exterior crews, and the H-2B visa program is one alternative builders use to bring in seasonal siding and roofing workers.
Estimating Labor for Shake Installation
A two-person crew installs 800 to 1,200 square feet of polymer shake in a day on a straightforward wall, depending on exposure and cut complexity. Dormers, peaks, and openings cut that rate by a third or more. Budget a day for staging and layout before the first course, and confirm the delivery date before the crew is booked.
Installation follows a sequence: starter course at the base, backer or drainage plane behind the panels, fasteners placed per the manufacturer’s schedule, and trim flashed at openings and corners. Crews that have run the material before move noticeably faster, which is one more reason dealers keep installer relationships warm.
Incentive Programs and Market Demand
Demand-side programs shape what gets installed as much as supply chains do. Utility rebates, code updates, and local incentive packages change the economics of an exterior upgrade, and dealers track those programs because they drive counter traffic.
Local incentive programs can shift an entire market. The San Antonio solar energy incentive program for home builders is one example of how municipal programs move demand toward energy-conscious envelopes, and siding and window choices ride along with those upgrades.
Warranty documentation matters when incentives are involved. Keep the manufacturer’s installation instructions, color codes, and purchase records together, because transferable warranties and program paperwork want the same evidence.
Reading Local Market Signals
Contractors who watch incentive calendars and code cycles can time their siding promotions to when homeowners are already planning envelope work. The material itself has not changed in four decades; the programs around it have, and that is where the opportunity sits.
