# What is a Square in Roofing? Installing Your Shingles Properly

What is a square in roofing? It is a measurement of the length, width and angle of a roof’s ridge and span. Roofs differ in this dimension, for instance an Atlanta home has twice as many shingles on each side of the home compared to a New Jersey home. The calculation of a square in roofing is simple: divide the total of the ridge and span of your roof by 100.

To figure out the exact number of squares on your roof just divide its height by 100 ( 2400 This means you’d have 24 squares of roofing square to cover the entire roof)

In order to find out what is a square in roofing you can use a software called Roof-O-Jacking. This is a program that is designed for home and business owners. All you have to do is enter your roof dimensions, select a template from the hundreds available, and then select the shingle you want on your roof (these come in a variety of colors, sizes and textures). The software will calculate the exact square footage of your roof and give you the same measurements for every square foot.

Another way of figuring out what is a square in roofing is to take a tape measure and draw a straight line down the center of your roof and across each of your roof squares. Once you have the distance and width measurements you need, cut your cardboard pieces and set them aside. This cardboard is the template for the rest of your roof. Measure the length, width and height of your house from the ground up, then take a measuring tape and measure your roof squares. Multiply the two measurements together to get the square footage.

Now for the fun stuff! Once your square footage is measured, it’s time to get to work. Grab some of your brava tiles, measuring cups and putt-putts. Tiles come in different shapes and sizes and therefore you will need the proper shingle type for the roof materials you are using. Some people prefer the thicker shingles while others prefer the thinner shingles.

Once you have selected a shingle type, cut your squares and place them carefully onto your roofing materials. Use some tar paper to smoothen the edges of your shingles. Before you know it, you’ll have a perfect square in roofing.

Before installing your shingles, lay a plywood or other protective sheet over the area where your shingles will go. This will help protect the plywood from damage during the installation process. Keep in mind that your final roofing square should be approximately three to four times longer than your roof’s length. The reason for this is because the roofing materials’ length dictates how many nails or tacks they need to be held into the roofing square.

After you’re done installing your shingles, you may want to go ahead and nail down the corners. You can then cover up the nails with more roofing materials. Once everything is covered, you can then install your brava tiles. If you’re having trouble with any part of the installation, you can call on your roofing contractor.
