One must learn about roofing estimate and all its complexities broadly. In measuring a roof, first and foremost, measure the roofing coverage surface area, which is measured in roofing squares so that you can get accurate roofing estimate. One roofing square is equivalent to 100 square feet. Next is, convert your roof area to “roofing squares”. Converting of the area in square feet to roofing squares is accomplished by dividing the total raw area obtained in multiplication, by a 100. For example, if we were to divide 1500 square feet area by 100, then we get a surface area size of 15 squares for ground measurements.
In roofing estimate also, you must determine the roof pitch. There are actually three categories of roof pitches. The first one is the Low Roof Pitch/Slope. This type of roof would have at least a 3:12 pitch, which means that a roof rises 3 feet for every 12 feet of its base horizontal length. This type of roof is considered to be “walkable”, and easy for performing a roof installation. Next is, the Medium Roof Pitch/Slope that would fall within 6:12 – 9:12 roofing slope range. It requires special equipment such as roofing jacks, and planks in order to be able to perform the roofing installation. Last but not the least, is the High/Steep Roof Pitch/Slope. Roofs in this category have a slope that is greater than 9 inches of rise for every foot of horizontal roof’s run.
