The first step in measuring a roofing square is to determine its length and width. The square footage will be a combination of the length and width of the roof. For example, a roof that is 35 feet long by 36 feet wide has a total area of 1260 square feet. This is an average area, and it is common to measure larger areas for slanted roofs. However, if you’re unsure of your exact measurements, it’s best to contact a roofing contractor. commercial roofing

When measuring roofs, you can use a ruler that measures roof squares to determine the amount of material you’ll need. The ruler contains a list of measurements equal to 100 square feet, which roofers use to estimate materials and labor costs. But even if you’re confident you can calculate the amount of roofing material you’ll need on your own, it’s still a good idea to follow these steps first.

First of all, roofing squares are easy to understand. A roofing square is 100 square feet, so a two-story home has 20 roofing squares. For an average roof, this is a simple calculation, but you should consider some factors. You should not worry about headlap, as most calculations don’t include it. In fact, you should always add 15% to your estimate, so that you don’t underestimate the amount of material you’ll need.

When you have your roof squares, it is important to use the right tools and wear protective clothing while you work. Measure your length and width and divide this value by 100 to get your roofing squares. This conversion isn’t hard if you have the right tools. For more information, see the article below. The best way to calculate roofing squares is by using the calculator. But be sure to consult a roofing contractor before you get started.

Another thing to remember when you measure roofs is that not all houses have square roofs. Your roof’s complexity and stiffness will change the way you compute the data. For example, if the roof is gabble or sloped, you should multiply the square footage by 1.4. You may need to calculate additional material, especially if it’s a steep roof. The calculator will also give you a rough estimate of the total amount of roofing material needed.

Once you’ve calculated the square footage of the roof, calculate how many shingles you’ll need. You can estimate the total number of shingles by dividing the area by 100 and multiplying by three. But remember that you’ll have to cut off some of the squares to account for waste, so rounding the numbers before multiplying and adding can lead to inaccurate results. In short, measure carefully to avoid making mistakes.
