Along with hammering and tearing, Orange County Roofers must do a certain amount of calculating. The calculations are the precise roof measurements taken prior to the commencement of a roof installation. By taking these measurements, professionals determine the number of shingles needed for a job.

An Orange County Roofing Company begins the calculating process by sketching a diagram of the property. The drawing needn’t be a masterpiece – just a simple graphic representation that provides basic information such as home shape and location of front, back, side, etc.

The first actual calculation takes place when a professional measures a home’s perimeter. To arrive at this number, contractors use a tape measure to ascertain the length of all outer walls, as well as any other sections such as the garage.

Once the perimeter is known, Orange County Roofers calculate a roof’s square footage. This measurement, however, is only part 1 of a two-step process. For step 2, roofers convert the square footage into a number known as a ‘roofing square’. What exactly is a roofing square? In a nutshell, this is a 10’ x 10’ area (or 100 square feet) of rooftop. So, if a roof measures 1000 square feet, Orange County Roofers will be covering the equivalent of 10 roofing squares.

For the final calculation, roofers also must measure and factor in a roof’s slope. With this number in hand, they at last can determine the precise number of shingle bundles to order. (Shingles are not sold individually but in bundles.)
