If you mean square feet, there are 100 square feet in a square. So 20 squares is 2000 square feet.
To determine the number of squares in a 20x20 gabled garage roof, we first need to understand that a "square" in roofing typically refers to a 100 square foot area. A 20x20 roof has a total area of 400 square feet (20 feet x 20 feet). Therefore, the number of squares in the roof is 400 divided by 100, resulting in 4 squares.
When talking about the area of a roof, remember that it is not the same as the square footage of the structure. For example a 20 x 30' building with a 12" overhang and a 4/12 pitch will have 736 sq ft of roof vs only 600 sq ft of slab. One square of shingles covers 100 square feet. 15 year shingles come 3 bundles to a square. 25 year come 4 bundles to a square.
It depends on the brand and type but conventional shingles of a good grade would be about 225 lbs.

It is a "LIVE LOAD" which is the weight of snow for which a roof is designed for. It is usually 40 lbs. per square foot. Al dead load is the weight of the roof structure itself.
If you mean square feet, there are 100 square feet in a square. So 20 squares is 2000 square feet.
A roof that is 10 x 20 has an area of 200 square feet. The cost to have this size roof shingled is approximately 1,800.00.
Care must be taken in calculating the roof weight of a floating storage tank. The amount of weight per square foot is the most important measurement and must take into account the fluid nature of the whatever is being stored. Checking the ability of the roof to hold the weight is another important fact to not overlook.

Surface area of the roof times depth of snow gives volume of snow. Take a sample of snow and weight it to determine density (since the density of snow can vary quite a bit). Density times volume equals weight.
The weight of concrete roof tiles can vary, but on average, they weigh between 9 to 12 pounds per square foot. Therefore, 100 square feet of concrete roof tiles would weigh approximately 900 to 1,200 pounds. It's important to check the specific weight of the tiles being used for a more accurate calculation.

at least 25 bundles With an average of 3 bundles per square(100 square feet) an 8 square roof would need 24 bundles plus 1 for cuts and shorts.
