How to Measure a Roofing Square
One of the terms you’ll hear as a homeowner starting a roof repair or replacement is “roofing square.” Understanding how these measurements work can be critical to knowing exactly how much material you need.
A roofing square is a standard unit of measurement for measuring the layout, shape, and size of a roof. It also helps to provide a method for determining how much roofing material is needed, from asphalt shingles down to the underlayment.
Measure the Roof’s Length
There are a few different methods that you can use to measure the roof’s length. One method involves climbing up on the roof and using a level. Another method involves estimating the slope of the roof from the ground.
To use the level method, you’ll need a ladder that can reach the roof’s edge, a measuring tape, and a two-foot level. You’ll also need safety equipment to keep yourself safe as you climb up.
When you’re on the roof, take your measurements carefully and jot them down on a notepad or paper. This will make it easier to compare the different measurements when you’re finished.
Depending on the shape of your roof, you may have to calculate each section individually. For flat roofs, these sections are called “planes.” The more architectural details your roof has, the more planes you’ll need to measure.
Measure the Roof’s Width
Before attempting to climb on your roof, make sure you have a ladder that is safe for you and your family. You should also wear work boots with proper traction.
Once you’ve secured yourself to the roof, use a tape measure to record your measurements precisely. Write each measurement down to the nearest half inch (1.3 cm) so that you can calculate your roof’s square footage later on.
You can do this by measuring the length of each plane on your roof and then multiplying that number by its width. This will give you the square footage of each plane on your roof, which you can then add together to calculate your total square footage.
Using this method can help you estimate the amount of roofing materials you’ll need to replace your roof. But if you’re not confident in your ability to do this, it may be best to leave this to a professional. Regardless, it will save you money in the long run by giving you an accurate estimate of the amount of roofing materials you’ll need for your project.
Measure the Roof’s Pitch
The roof’s pitch is a critical element of nearly every roofing project. It helps you determine the right materials to use, estimate appropriate levels of drainage, and much more!
If you have access to your roof, there are a few different ways to take an accurate measurement. One of the most common is to measure from the rafters.
Typically, you need a bubble level and a tape measure to complete this measurement. Once you have these items, simply position the end of the level against the underside of a rafter in your attic.
Once this is done, you can easily take a measurement and arrive at an accurate pitch calculation in no time.
Traditionally, you can find a roof’s pitch by measuring its rise and run, then dividing the rise by 12. That results in a ratio of “x:12.” However, you can also measure it in degrees or use a calculator to simplify the process.
Measure the Roof’s Height
Measuring the height of a roof is critical for estimating materials and providing an accurate estimate to your client. It is also important for safety and zoning purposes.
First, find out how tall the roof is from its base to its peak. You can do this by measuring from the ground or getting up on the roof.
If you’re not comfortable climbing a ladder, measure the height of your roof from ground level using a long tape measure and an assistant. Make sure you get the measurements accurately and don’t round up or down before making calculations.
Once you have these measurements, multiply them by the pitch of the roof to calculate the square footage. This information will help you determine how much material to order and how many shingles your roof needs.
