To determine the number of bundles needed for a roofing project based on square footage, the exposure and type of material play crucial roles. Each bundle of cedar shakes typically covers 20 square feet. Using the standard calculation, four bundles cover one square (100 sq. ft.). For cedar shingles, one square equals four bundles as well. Thicker shakes, such as heavy split and resawn, have specific exposures that further influence how many bundles are required; e. g., an 18″ shake pack may require seven bundles per square, while a 12/12 pack might only need five.

To accurately assess material needs for a specific area, divide the square footage by the coverage determined by the exposure. A standard bundle of white cedar shingles provides coverage of 25 sq. ft. at a 5 in (12. 5 cm) exposure. Thus, the calculation for a roof measuring 3200 square feet would incorporate the total area and adherence to the exposure rates.

For converting square footage to lineal footage, use the formula: square footage multiplied by 12, divided by the bevel exposure. The industry standard states that five bundles are packaged per square when using taper sawn shakes, which provide a distinct aesthetic due to their thicker profile.

When planning material requirements, consider the ratio of bundles to squares, understanding that for shingles, it remains four bundles per square while for shakes it’s five bundles per square. Therefore, when estimating, if needing to cover 816 square feet, approximately 8-81/2 squares, or 34 bundles, would be necessary. Proper calculations will ensure adequate and accurate ordering for the roofing project using these materials.

How many bundles of asphalt roofing shingles per square? Seems like a an easy question, right? Well, if you’re a roofer, this …

18″ shake bundles require different numbers of bundles per square: 9/9 pack needs 7, 12/12 pack needs 5, and 15/15 pack needs 4. Coverage of 100 sq. ft. is based on the 12/12 pack with a 7½" exposure, influencing required bundles per square. Typically, three bundles cover one roofing square, although some architectural shingles may need four. Shingle bundles generally cover about 33 sq. ft. each, leading to the standard of three bundles for one square.

However, cedar shingles may require four bundles per square. To calculate board footage, use thickness times width divided by 12 times square footage. Always check with suppliers for specific bundle sizes when ordering.

To cover one square (100 square feet) of roofing, approximately four bundles of cedar shingles are needed, though this can vary with shingle size and installation method. For 816 square feet, you will require around 8 to 8. 5 squares, which translates to about 34 bundles. When calculating, divide total square footage by 100 for squares needed, then apply the four bundles per square rule. Additionally, account for extra bundles based on specific measurements of eaves, rakes, and valleys. A typical bundle covers about 33 square feet, necessitating three bundles per 100 square feet under standard exposure conditions. Waste factors should also be considered in planning.

A bundle of cedar shingles generally covers about 25 square feet and contains 70 to 100 individual shingles, depending on size and thickness. An important factor is that shingles are doubled along eaves and rakes, which necessitates adding an extra bundle. For instance, if covering a roof with a total area of 1000 m² using shingles with an area of 0. 5 m² each, the calculation is 1000 m² divided by 0. 5 m², resulting in a requirement of 2000 shingles.

When using 16" Certigrade shingles at 4" exposure, the coverage table indicates that for effective coverage, about 34 bundles or 8 to 8. 5 squares are necessary. It's notable that while a typical bundle might cover 33. 3 square feet in some cases, standard coverage is accepted as 25 sq. ft. if the exposure is at 5 inches. To cover a full square (100 sq. ft.), usually four bundles are needed. The number of shingles in a bundle can range from 15 to 29, and for custom calculations, knowing the specifics of a bundle's size and shingle exposure is essential. As a guideline, 1 square equals 4 bundles, thus understanding these conversions is critical for accurate estimations when budgeting roofing needs.

These 24" Heavy Cedar Shakes are ideal for various structures like homes and gazebos. Thicker than standard shakes, they measure approximately 3/4" at the butt and taper to 1/16" at the tip, with a 10" exposure providing coverage of one square per five bundles. Premium Grade 24" Western Red Cedar Tapersawn Shakes are low-maintenance, machine-sawn with smooth surfaces. The minimum width is 4 inches.

Additionally, the Western Red Cedar Hand-Split Shakes are CCA treated and range from 1/2" to 3/4" in thickness, with clear heartwood and edge grain, ensuring quality for roofing applications. Various grades and thicknesses are available.

A bundle of cedar shingles typically weighs between 70 to 80 pounds, influenced by thickness and moisture. To cover one square (100 square feet), you'll need about four bundles of cedar shingles. Wood shingles vary in weight with cedar shingles averaging 40 to 50 pounds per bundle, while redwood shingles range from 50 to 60 pounds. Most modern architectural shingles weigh between 60 and 80 pounds per bundle. Asphalt shingles weigh around 45-60 pounds, with wood shingles weighing 200-700 pounds depending on type.

Cedar shingles' dry weight can be between 160 to 320 pounds per square, with bundles weighing 40 to 80 pounds. A 3-tab bundle typically weighs 45 to 60 pounds, and an architectural one ranges from 200-600 pounds per square. Generally, one bundle covers one-third of a roofing square, impacting weight calculations based on material. For instance, a bundle of 3-tab shingles weighs about 45-60 pounds while architectural shingles weigh 60-80 pounds. Cedar shingles are among the heaviest, with normal bundles reaching up to 85 pounds.

Moisture content affects weights significantly. A specific example includes Grade 18" Perfection Western Red Cedar Shingles requiring 4 bundles to cover a square with weights varying based on moisture. Stainless steel annular ring nails are recommended for fastening—1kg suffices for 4 bundles using two nails per shingle. In summary, understanding the weight of shingles is essential for proper installation and safety considerations.
