Pre-primed cedar sidewall shingles can simplify preparation before a finish coat, but the right choice depends on shingle length, surface texture, carton coverage, and the wall’s design. The 18-inch natural-groove 1-square cartons are best for larger projects with a stated coverage figure; the half-square cartons suit smaller areas or staged purchases. Choose circular-sawn or sanded shingles when that surface treatment better fits your project. The products below are listed for sidewall use.
| Product | Length and finish | Stated coverage | Best suited for |
|---|---|---|---|
| Natural-groove 1-square carton | 18-inch, grooved | 100 sq. ft. at 14-inch exposure, double coursed | Larger standard sidewall areas |
| Natural-groove 1-square carton, alternate listing | 18-inch, grooved | 100 sq. ft. at 14-inch exposure, double coursed | Comparing the same specified format |
| Circular-sawn half-square carton | 18-inch, circular-sawn | 50 sq. ft. at 14-inch exposure, double coursed | Smaller areas with a sawn texture |
| Natural-groove half-square carton | 24-inch, natural groove | Not stated in the product details | Projects requiring 24-inch shingles |
| Sanded half-square carton | 18-inch, sanded on one side | 50 sq. ft. at 14-inch exposure, double coursed | Smaller areas with a sanded face |
18-Inch Natural-Groove Cedar, 1 Square
This carton contains 18-inch, kiln-dried, high-grade #1 cedar shingles. The shingles are rebutted and rejointed (R&R), grooved on one side, and designed for sidewall application. The listed coverage is 100 square feet at 14-inch exposure when double coursed.
Best for: Buyers covering a larger wall area who want the stated 1-square carton coverage and a grooved surface. It was selected because the product details specify both sidewall use and a clear coverage figure. Confirm the project’s layout and exposure before ordering; the listed coverage depends on the stated installation configuration.
18-Inch Natural-Groove Cedar, Alternate Listing
This listing describes 18-inch, kiln-dried, high-grade #1 R&R cedar shingles with a groove on one side. It is intended for sidewall use and states that one carton covers 100 square feet at 14-inch exposure with double coursing.
Best for: Buyers comparing listings for the same specified size, surface, and coverage as the first option. The product details provided are substantially the same, so compare the listing information and carton details carefully rather than assuming a different shingle specification. Avoid relying on the coverage figure if your planned exposure or course arrangement differs.
18-Inch Circular-Sawn Cedar, Half Square
This half-square carton contains 18-inch, kiln-dried, high-grade #1 R&R cedar shingles with a circular-sawn surface. The shingles are specified for sidewall application, and the listed coverage is 50 square feet at 14-inch exposure with double coursing.
Best for: Smaller sidewall areas where a circular-sawn face is preferred and a half-square carton matches the estimated need. It was selected for its distinct surface treatment and stated coverage. Measure carefully and allow for project layout needs; the 50-square-foot figure applies to the listed exposure and double-course arrangement.
24-Inch Natural-Groove Cedar, Half Square
This option is a 24-inch R&R cedar sidewall shingle made from Miller Shingle #1 shingles. The product details identify it as primed, natural-groove, and manufactured in Granite Falls, Washington, USA. Unlike the 18-inch options above, the provided details do not state its carton coverage or exposure.
Best for: Buyers whose design or project specification calls for 24-inch shingles. It was selected to provide a longer-size alternative in the product list. Confirm the carton’s coverage and applicable exposure before calculating quantities, because those figures are not included in the supplied product information.
18-Inch Sanded Cedar, Half Square
This half-square carton contains kiln-dried, high-grade #1, 18-inch R&R cedar shingles. One side is sanded, and the shingles are designed for sidewall application. The listed coverage is 50 square feet at 14-inch exposure with double coursing.
Best for: Buyers handling a smaller area who specifically want shingles sanded on one side. The stated carton size and coverage make it easier to compare with the circular-sawn half-square option. Choose this only if the sanded surface fits the intended appearance and installation plan; coverage changes if the exposure or coursing differs.
Buying Guide
How much coverage do you need?
Measure the wall area to be covered, then compare it with the product’s stated coverage. The 18-inch 1-square options list 100 square feet at 14-inch exposure with double coursing. The 18-inch half-square options list 50 square feet under the same conditions. These are project-specific coverage figures, not universal estimates. Add any extra quantity your layout or cutting plan requires.
Should you choose 18-inch or 24-inch shingles?
Choose based on the project design and its specifications. The 18-inch products in this list include explicit coverage information, while the 24-inch listing does not. For the 24-inch carton, verify coverage, exposure, and installation requirements with the seller or product documentation before estimating how many cartons to buy.
Which surface treatment is right?
Natural-groove, circular-sawn, and sanded describe different listed surface treatments. The supplied details do not establish that one surface performs better than another. Select the face that suits the appearance and project requirements, and confirm which side is intended to face outward.
What does R&R mean here?
The listings identify these shingles as rebutted and rejointed (R&R). They are described as sidewall shingles, not as a general-purpose product for every application. Check the project plans and installation guidance to ensure the shingle type and exposure are appropriate.
Frequently Asked Questions
Are these cedar shingles pre-primed?
Each product name identifies the shingles as primed. The supplied details do not specify primer type, color, or finish-coat requirements, so check the product documentation for those details.
How much area does one 18-inch carton cover?
The 1-square listings state 100 square feet, and the half-square listings state 50 square feet. Both figures are based on 14-inch exposure with double coursing.
Are these products intended for roofs?
The product details describe them as designed for sidewall application. Do not assume they are suitable for roofing without separate product documentation confirming that use.
Does the 24-inch option cover 50 square feet?
The supplied details do not state its coverage. Confirm the coverage and exposure for that carton before ordering.
