Asphalt Shingles You need to be aware that most jurisdictions allow only two layers of shingles to be applied to the roof due to the load considerations. For example, a 15-square area of roof with two layers of average 250-pound shingle has a total weight of covering of 7,500 pounds, or nearly 4 tons of weight. The under layer for asphalt shingle is usually roofing felt with a course of ice and water shield covering the lowest 3 feet.

Since a square of roofing is 100 square feet, a roof of 25 squares will require 12.5 rolls of 30-pound felt. (25 x 100 = 2,500 SF; 2,500 divided by 200 = 12.5 rolls.) Waterproof underlayment provides extra protection.

In fact, the weight of the stone ballast is the only item holding the roof components in place. The weight can vary from 10 pounds per square foot (the minimum allowed by code) to 25 pounds or more. The most common assembly was a loose-laid EPDM membrane over a rigid insulation board.

- Standard Weight. Standard asphalt shingles generally weigh about 190 pounds per 100 square feet, based on information from U.S. Inspect, a property inspection company. The weight of asphalt is especially important if you want to install a new layer of asphalt roofing over an existing layer.A roof measuring 1,600 square feet that has two layers of standard asphalt shingles on it is holding about 6,000 pounds of shingles..S. Inspect indicates that dimensional shingles can be 50 percent heavier than standard asphalt roofing. Therefore, they could weigh about 285 pounds per 100 square feet. Heavier shingles reduce the chance the underlayment will wrinkle, according to the National Roofing Contractors Association.

- Measuring Weight of Snow and Ice The weight of accumulated snow/ice, not the depth, is critical in assessing a roof’s vulnerability. The water content of snow may range from 3% for very dry snow to 33% for a wet, heavy snow, to nearly 100% for ice. An inch of water depth weighs 5.2 lbs. per square foot. Thus, a roof designed to carry a snow load of 20 lbs. per horizontal square foot is expected to support nearly 12 inches of wet, heavy snow.

Donât Fall Short on Shingles: How to Estimate Materials for Roofing Projects If the shingles you are using come three bundles to a square, calculating the number of bundles you’ll need is simple. Each bundle covers 33.3 sq. ft. of roof area—close enough to the 32 sq. ft. a sheet covers. So just order one bundle for each sheet of roof sheathing. For other bundle counts per square, divide the number of sheets of sheathing by three and you’ll have the total number of squares needed to cover the roof.

How Much Do I Need? Then, add the two planes together to derive the total square footage of the roof: 1  Plane 1: 120' x 100' = 12,000 sq. ft. 2  Plane 2: 120' x 100' = 12,000 sq. ft. 3  Plane 1 + Plane 2 = 24,000 sq. ft. for the total square footage of the roof. Roof surfaces are measured in squares. A square is an area of roof which measures 100 square feet. To determine the number of squares on the gable roof above, simply divide its total of 24,000 square feet by 100. The result is 240, and this means you would need 240 squares of shingles to cover that roof.
