# How to Figure Out How Much Roofing You Need For Your Home

There are several ways to figure out how much roofing you need for your home, but the most accurate way is to measure each square of the roof area. For example, a 15 by 30 foot roof will require about 450 square feet of roofing material. Then multiply that number by two to get the total area of the roof. For a roof that measures 4,200 square feet, you’ll need 42 squares of shingle material. Usually, roofing material is sold in “squares.” Depending on the type of shingles you’re selecting, you might have to purchase more than one bundle, so you should account for that. commercial roofing

One way to figure out the square footage of your roof is to calculate the total area of the roof itself. You can do this by measuring the length and width of the roof. Then, add the square footage of each plane. This will give you the total area of the roof. This calculation is particularly useful when you’re dealing with a simple gable roof, because the roof area is the same. A more complex roof, however, requires a more detailed calculation.

A simpler approach is to use a drawing program. You can use a program such as AutoCAD to determine the square footage of a roof. Simply take the area of your roof and multiply it by two. You can also use a measuring tape to measure the length and width of any irregularities. Afterward, change the area measurement to square feet. If you are not sure of the total square footage, make sure to consult an architect or roofing professional for assistance.

Taking measurements of your home’s footprint can also help you estimate how much roofing you need. Taking measurements from above will not account for the roof’s pitch. This makes the calculation difficult, and underestimating roofing material can be costly. Fortunately, there are a number of online tools that will make the process simpler. You can even use Google Maps to see how your property will look when you finish, and a 3D view of the roof’s shape will show you exactly what you need.

A simple way to estimate the amount of roofing material you need is by calculating the square footage of the roof area. Depending on the type of roof, you may need to divide the total square footage by three. Each square will equal approximately 33 square feet, and the waste will be the material cut off or overlapped. Remember to factor in a waste factor of 10% to 20% of the total square footage. For roofing installation, you will also need to order a shingle bundle and roofing nails.

In addition to measuring your roof area, you need to calculate the amount of nails you’ll need for the entire project. You’ll need to measure eaves, rakes, and drip edge. These measurements will be the basis for estimating the number of nails you’ll need for your roof. If you’re unsure about the amount of nails you’ll need, simply multiply the square footage by four.
