You must know the answer to this question before you go on with the building process. Asking how many square feet are in a roofing square yard is like asking how many inches of an apple are in a half-inch cube. The size of the roof will not change but the measurement will be incorrect. It is all relative.

The same goes for your roofing project. You cannot make a calculation that will suit the requirements of your roofing company without knowing how many square feet are in a roofing square yard. That is the very basis of the whole project. To put it simply, you cannot calculate how many materials you will need or how many roofing shingles you need based on the information you get from them. The best calculation you can use is to estimate the square footage by using the square footage of your home as your base measurement. In your case, that would be the number of rooms in your home.

Using the square footage of your home as your base measurement, multiply this measurement by the number of rooms in your home. For example, if you have a room with a floor area of 12 square feet, then you would need to estimate the number of roofing square yards needed for the entire project. For the purpose of calculation, you should round up to the nearest whole foot. The reason why is because when you do rounding to the nearest whole foot, you will probably get digits that are very close to each other. But they are still not the same because even a fraction of a penny or a single square inch could change your calculations immensely.

When you multiply the number of square yards by the square footage of your home, you will arrive at the amount of square feet needed for the roofing project. You can find this number by dividing the total square footage of your home by the number of square footages used for the calculation. Hence, you will know how many roofing square yards you will need.

The next thing that you need to know is what the square footage of your roof actually is. When you get your base measurement, add four to the square footage to get the total square footage. Then multiply this by the number of rooms in the home, which will give you the total square feet of the whole project. This will help you determine how many roofing square yards you will need.

Once you know how many square feet are in a roofing square yard, it is time to do some math. multiply the number of square feet by the total square footage and come out with the approximate number of nails you will need. Use these nails, which are pre-drilled and of the right size, to hang up the first panel. After doing this, you will know how many square feet you will need. Hold the square footage against the actual square footage to get an exact estimate. You do not want to have more or less than this number when installing the roof.
