Unless you have a flat roof, no; the surface area of the roof will be larger than the ground area of the building.

My home is 1100 square feet what is the roof's square footage?
You cannot calculate the square footage of a house roof like this (unless you have a flat roof). The simplest way would be to go up on your roof and measure its different surfaces, however if you dont want to do that, you would need to know several differen things to calculate the surface area -- such as the pitch and angel -- how much hangover you have. Basically you should save yourself time and go up on your roof and measure it
How do you figure roofing number of squares on roof?
You measure the roof to get the square feet. There are 100 square feet in a square. On a straight single peak roof it's height times length on one side and double it. Then divide the total square feet by 100. This final number will give you the number of squares you have. If the roof is a flat, commercial roof, it is the same (100 sq. ft = 1 SQ). However, if it is a metal panel commercial roof, you need to add in "stretch factor" or the added amount of square footage if the panels were to be stretched flat. A good estimate for this is: If the ribs on the metal panel are 1" tall, add 10% to your square footage; if the ribs are 1.5" tall, add 15% to your total square footage. So, if you have a metal roof that is an R-panel (_/-\_), the ribs are 1.5" tall and the roof is 100 SQ (or 10,000 sq ft), take 10,000 sq ft + 15% (1500) = 11,500 sq ft (115 Squares).
Your house is 1350 square feet how many shingles do you need?
The square footage of your house is not the same as the square footage of your roof if there is any pitch. If you are asking aboutasphalt shingles, generally each bundle covers 33.3 square feet. Therefore find the square footage of your roof, divide it by 33.3 to find the number of bundles, then multiply the original square footage by 5-10% to get the number of additional bundles for cutoffs and starter strip. The variation in percentage accounts for the number and length of valleys of the roof. Example:[@5%]roof =1500 ft2 --> (1500/33.3=45.05) (1500x.05=75 -->75/33.3=2.25)45.05 + 2.25= (48) bundles

How do you measure your shingles on roof?
You just have to measure it. Height times width and double that for simple roofs. Lots of angles or dormers will have to be allowed for. 3 bundles in a square. 1 square covers 100 square feet. Height times width gives you the square footage and do the math. Assuming you are talking about asphalt shingles they can be up to 5 bundles per square if you are using dimensional shingles. the standard flat three tab shingles are 3 bundles per square. You can calculate roof area just based on the dimensions taken on the flat. There are different multipliers to use that depend on the pitch of your roof.
How can a homeowner calculate the size of their roof?
Use the square footage of your house, and the size of your roof should be about the same. Be carefull not to include the yard in the footage or anything that is not covered by the roof, then divide the number by the number of stories your house is.
