Total Roof Area Of Cities

San francisco is an extreme example.

Total roof area of cities. Calculating the surface area of a sloped roof can be time consuming without the right tools. Start the project with a roof area calculator. 1 200 x 1 05 1 260 square feet to allow for hips ridges and waste add 10 of your final number for a gable roof and 17 of your final number for a cottage roof. This list ranks the top 150 u s.

Water makes up nearly 80 of its total area of 232 square miles 601 km 2. The total will not equal their added values as the calculator subtracts the hidden area from roof 1 at the intersection and displays only the actual exposed roof area for the total. Measure their green roof area in thousands of square feet stuttgart can measure its in millions. After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof.

Total areas including water are also given but when ranked by total area a number of coastal cities appear disproportionately larger. Calculating area is easy in two dimensions but nearly all roofs slope up to a peak which adds a third dimension. The values calculated for roof 1 and roof 2 are independent. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

And that s the number you were looking for. To do that you need to accurately calculate the area of your roof. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. While most cities in the u s.

Your total number would be either 1 386 or 1 474 square feet. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. To accurately calculate the area of your roof you must first determine its slope or pitch. While it is possible to estimate the amount of necessary materials using only the total roof area measurement as can be seen from the table depending how large the pitch of the roof the actual area of the roof can differ by up to 2 236 from the measured total area at a pitch of 24 12.

You cannot enter values for area 2 alone. And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier. The google maps area calculator is not 100 accurate. Some 20 to 25 percent of the city s flat roofs are green and due to a combination of government incentives tax abatements and regulations so are 10 percent of the roofs throughout germany.

Also in many cases a city may be. Next multiply the area by your roof s pitch. That gives you 5 590 square feet which is the actual area of the surface of the roof. Cities by land area.
