How to Figure Roofing Squares
Knowing how to figure roofing squares is essential when estimating a roof’s roof coverage. It can make a difference when you’re deciding on which shingles to use. Prepackaged asphalt shingles, for example, are sold in bundles of three shingles each. To calculate how many bundles you need per square, multiply the number of roofing squares by three. If you have 20 squares to cover, you’ll need 60 bundles of asphalt shingles. residential roofing
Generally, the number of roofing squares is easy to calculate when constructing a standard gable roof. The roofing contractor will measure the length and width of each plane, which form the two sides of a triangle. Once the length and width of each plane are known, the slope of the roof is easily determined using the Pythagorean Theorem. However, some roofs have more complicated designs with ridges, turns, and valleys. In these cases, a calculation for squares is not as easy.
Roofing squares are another important tool when estimating the cost and size of a roof. Knowing how many squares you need is an important part of estimating the cost of materials and labor. However, this method is best left to an experienced roofing contractor if you’re not sure of how to measure the roof properly. If you’re confident in your measurement abilities, you can still follow the steps mentioned above to figure out the correct amount of material and labor needed to cover your roof.
One of the most important things to remember when estimating the size of a roof is that squares are the smallest unit of roofing material. The square is equivalent to 100 square feet, so it’s important to know exactly how many squares your roof will need. If you don’t know how to figure roofing squares, you may end up ordering too much material. This will make your roof look too crowded and may result in an expensive mistake.
To figure roofing squares, take one slope at a time. Then, divide that measurement by the width and length. Once you’ve done that, multiply the two sides of your roof together to get the area. Now, change the units to square feet to get the final figure. If you’ve already got a rough sketch of your roof, you’ll need to take measurements according to this. Once you’ve got a rough estimate of how many square feet you need, you can use it as a reference.
When you figure roofing squares, you’ll know how much material to buy. In addition to knowing the squares, you’ll need to factor in the amount of trim and waste that you have on your roof. You’ll need approximately ten squares of asphalt shingles for every two hundred square feet of roof surface. However, the squares should also include a ten to fifteen percent waste and trim allowance, as you’ll need to buy more material if you’re building in a rainy or humid area.
