Is Roof Area Just The Total Area Of The Building

How are total total living used.

Is roof area just the total area of the building.

The roof slope height is 6 98m. 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. Determine the area of the roof s footprint which is the area covered by the roof regardless of slope or the apparent area of the roof when you look straight down at it like from a satellite. Eaves and other architectural projections are not included in building area.

Adding to this confusion is the practice among some developers to use gross leasable area gla and gfa interchangeably or to use. In layman terms it s the area occupied by the building. This area includes garages porches patios and any area under the main roof. The length of the roof is 8 7m for this square house as 8 7m x 8 7m is 76m total floor space.

How to calculate the roof area using the building square footage the pitch of the roof. Because this is only one half of the roof we will need to double this number to find the entire roof area 121 45m. Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area. The definition of building area does not use the term gross although it would imply that based on a comparison of the definitions of gross floor area to building area also you have be careful when mentioning roof overhang as being part of the building area.

8 7m x 6 98m 60 73m. Definitions of gfa including which areas are to be counted towards it and which areas aren t vary around the world. Total square feet is just that. Gross floor area gfa in real estate is the total floor area inside the building envelope including the external walls and excluding the roof.

So for our example the half roof area is as follows. 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. Your total number would be either 1 386 or 1 474 square feet. Google earth makes this pretty easy but you can also simply measure the dimensions of the building on the ground and figure out the area that way.

This sometimes will include detached structures like detached garages guest suites or cabanas. Our roof calculator uses base length and base width to find the estimated area. Next multiply the area by your roof s pitch. The base width is the distance from one corner of your roof to the other at its base on the short side of your house.

For a single storey building it s the ground.
