Cedar shingles typically come in random widths, making it hard to determine the exact number needed. For example, a bundle of green shingles covers 25 square feet at a 5-inch exposure. However, at a 7-inch exposure, each bundle can cover up to 33 square feet.

Factors for coverage and exposure include the location of installation (roof or sidewall), pitch of the roof, type of material, and length of material. For precise calculations and to ensure you order the right amount, contact us.

Cedar shingles can last more than 100 years in the right environment with good maintenance. Roofing tends to have a shorter lifespan than sidewalls due to greater exposure to the elements.

For example, 16-inch roofing shingles are rated to last 30 years, whereas ¾” hand-split shakes can last 50 years. Fasteners, treatments, and painting or staining can extend their lifespan.

While some cedar shingles can be very expensive, cost-effective options are available — and these can last almost as long as top-tier shingles. Like lumber, the price of shingles varies with market conditions.

Cedar shingles might have a higher initial price tag, but with proper maintenance, they can last up to three times longer than composite shingles. Maintenance is simple: we recommend gently sweeping the shingles when dry to remove debris, then a gentle detergent for washing off any algae. The longevity of cedar shingles makes them a worthwhile investment.

No, cedar shingles are not waterproof. They are porous and absorb and release water based on the environment and weather. Some people apply a couple of coats of stain, which can have a waterproofing effect, but this is generally done on smaller projects or sidewalls. However, properly installed cedar shingles are one of the best ways to protect your house from the elements due to the three-layers of weather-protection when properly installed.

Logs are cut into rounds, then saws set at an angle taper and cut them into pieces. This differs from cedar shakes, which can be hand-split or sawn.

Cedar shingles can be treated to be fire retardant and achieve a Class A fire rating. While old, dry shingles will burn, cedar has a natural component of fire resistance and doesn’t burn as easily as spruce, pine, or fir. The fire retardant process creates a stable, fire-resistant roof without compromising the benefits of cedar.

Typically, green cedar shingles are not treated with chemicals. Some kiln-dried shingles, such as R&R (Rebutted and Rejointed), can be primed with chemical-based primers. They can also be pre-stained or pre-painted at the factory. Fire treatment chemicals can be caustic but are not harmful to people. CCA (chromated copper arsenate) can protect against mold and damage, though excessive exposure can be harmful.

Yes, cedar shingles can be painted or stained as long as their moisture content is 12% or lower, as measured by a moisture meter. We recommend purchasing pre-primed shingles if you plan to paint them, or pre-stained shingles, to save time and effort in installation.

If you are not in a hurricane zone, staples are an acceptable choice for installing sidewall shingles. However, nails are preferred because they have a longer lifespan, are more resilient to wind, and ensure better material integrity.

Buildings can have various types of sheathing, such as plywood or brick. On top of the sheathing, a 30-pound asphalt felt is usually applied as an underlayment. Additionally, many installers add a layer of breather material, which is a light plastic mesh that enhances breathability and helps remove moisture, extending the life of the shingles.

Power washing or pressure washing is not recommended except on the very lowest setting, as it can cause damage and necessitate replacements. To remove a layer of grime, use a very mild detergent, usually a water and bleach mixture. For debris removal from the roof, use a blower or broom. We recommend conducting maintenance when shingles are dry, as they can become very slippery in winter and debris is easier to remove when dry.

Yes, painting old cedar shingles is one of the best ways to extend their life. Before painting, fix nails and replace broken shingles. Use the right kind of paint for your shingle type, and test the paint in a small area before proceeding. Your local Sherwin Williams or hardware store should have a few options for you to choose from.

You should remove or replace cedar shingles when they crackle under pressure, when the majority of the roof is splitting, or if you dislike their appearance despite painting or other treatments.

A “square” refers to 100 square feet in roofing. Raw cedar shingles and shakes are typically packed in bundles. Each of these bundles covers a portion of a “square.” For example, shingles usually require four bundles per square. Shakes usually require five bundles per square.

The longest-lasting grade for siding is No. 1. Shingles graded No. 2 can also create beautiful and durable siding. Shingles graded at No. 3 and lower are not recommended, except as an undercourse for sidewall shingles or starter course for roofing.

Where you buy cedar wood shingles depends on your project size. For large projects requiring rooftop delivery with a crane truck, buy through a roofing supply store. For DIY projects, you can inspect and purchase shingles at a lumber supply yard. Please contact us for suggestions.
