How Big is a Square In Roofing? The answer to this question depends upon the type of roof you have and also upon where you live. A standard roof, such as an asphalt one, is approximately three quarters of an acre in area. Other types of roofs, such as slate and wood, are larger because of the materials used in their manufacturing. Regardless of the type of roof you have, your calculation of how big your square footage is in roofing will be based upon three factors: the amount of actual roofing you require, the total square footage in your roof, and the number of shingles used on your roof.
What is the total square footage of your existing roof? This is the most important factor when determining how big your new roof needs to be. The exact square footage of your existing roof is something you must calculate to the exact inch. To do this, simply measure from the top of the ceiling joist to the ground, and then to the floor. You will then divide the square footage by the actual square footage.
What is the total square footage of my new roof? The next step in your calculation of how big your new roof needs to be will depend upon the amount of actual roofing material you will need. The majority of homes have asphalt shingles. If your asphalt shingles are standard, you can assume that the amount of underlayment needed will be approximately equal to the square footage of asphalt shingles you have. Your underlayment will be made up of various types of material including fiberglass, plywood or concrete.
Will you be installing either single or tandem shingles on your roof? In most cases, single-shingles are used on single rafters. Tandem shingles are used on doubles or triples of rafters. This will help reduce the amount of underlayment needed because you won’t have to cut and stack shingles on top of one another. However, if you do use tandem roofing shingles, you will want to make sure they are the same size.
How many layers of insulation will I have? You will want to calculate the thickness of each layer in your total square footage before deciding how much insulation you will need. If you have a single layer of insulation, it will be best to have at least two layers of insulation in order to keep the cold out of your home and the hot inside. If your home is insulated well, the extra layer of insulation will help you keep your heating and cooling costs down. However, if your home is not well insulated, you may find that you will still need more insulation in order to keep your home comfortable.
What is the square footage of my roof? A square in the roofing industry is considered to be about thirteen hundred square feet. If your home is not quite as large, it will not matter as much. However, if you have a very large home or building, then you will want to make sure that you get this number. The reason for this is so that you can determine how much square footage your particular roof needs in order to protect it from weather damage.
