Multiply the two dimensions to get the area. The calculation will give you 320 square feet.
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.
The labor cost to tear off and replace shingles for a 1,200 square foot roof typically ranges from $1.50 to $3.00 per square foot, depending on the complexity of the job and regional labor rates. Therefore, for a 1,200 square foot roof, you can expect labor costs to be between $1,800 and $3,600. Additional costs for materials and other expenses would be separate. Always consult local contractors for more accurate estimates.
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.
To calculate the roof surface area needed to fill a 30,000-gallon tank with one inch of rainfall, you will need to know the collection efficiency of your roof. A common value is around 90%. With that efficiency, you would need a roof surface area of approximately 6,667 square feet to collect enough water to fill the tank from a one-inch rainfall.
If you paint one square metre of roof white you will save 107.5 kilograms of greenhouse gas equivalent over a twenty year period. If you paint your whole (1000 square feet : 93 square metres) roof white, you will save 10 tonnes of greenhouse gas equivalent over the twenty year lifetime of your paint.

96 square feet. Multiply length by width - the result is the area in square feet.
Multiply the two dimensions to get the area. The calculation will give you 1,008 square feet.
The length times the breadth in feet.

One bundle of shingle covers about 33 square feet of roof hence around 850 bundles of shingles will be needed for 28000 square feet roof!
To determine how many rolls of underlayment are needed for a 1500 square foot roof, you first need to find out how much area one roll covers. If a roll has 144 feet, and assuming it covers 3 feet wide (a common width for underlayment), it would cover 432 square feet (144 feet x 3 feet). Dividing the total roof area (1500 square feet) by the coverage per roll (432 square feet) gives approximately 3.47. Therefore, you would need 4 rolls of underlayment to cover the roof.
9 per foot. 9 times 24=216
what is the cost of a roof per square foot
Generally there is 1/3 of 1 square per bundle but this varies with style and manufacturer. a square covers 100 square feet of roof so 1 bundle would be roughly 33 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.
To calculate the volume of water from 1 inch of rain on a 1,320 square foot roof, first convert 1 inch of rain to feet, which is 1/12 feet. The volume of water is then calculated as the area (in square feet) multiplied by the depth (in feet). Thus, 1,320 square feet multiplied by 1/12 feet equals 110 cubic feet. Since there are about 7.48 gallons in a cubic foot, you would multiply 110 by 7.48, resulting in approximately 822 gallons of water.
