Step 2: How to Determine Your Roof Pitch
The next step is to measure the pitch (also referred to as the roof slope) of the roof deck. You’ll need to figure out the vertical distance (also known as the rise) over a 12” horizontal segment (also known as the run). Record these values as roof rise over run, with the vertical measurement listed first and the horizontal second.
It’s important to keep in mind that the roof pitch will be dramatically different for homes with a flat roof than homes with a steep roof.
Step 3: Calculating Roof Squares
Once you’ve determined the square footage of the roof, you can calculate how much roofing is needed to cover it. “Squares” are the units for roof measurements, which will help determine the number of shingles needed to cover an area and estimate costs. A “square” is an area which measures 100 square feet. To determine the number of squares on a particular roof, simply divide its total square feet by 100.
HOVER Roofing Calculator
Save time and reduce risks by using the HOVER roofing calculator app. Climbing a roof and taking measurements by hand can be dangerous and time-consuming. If you want to save time and reduce the risk of injury, we’d recommend you try the HOVER roofing calculator app. By taking just a few photos with your smartphone, you can get a fully scaled 3D model with accurate exterior measurements for the roof, siding, and all openings. This helps general contractors to quickly provide precise pricing estimations and visualize different materials and colors for homeowners. Try HOVER today – your first property is on us!
The purpose of calculating the precise measurements of a roof is to ensure that the appropriate amount of roofing materials are ordered – whether you have a shingles roof, gable roof or metal roof. Here are some common roofing materials and considerations for each:
Shingles are typically sold in bundles. Depending on the type and brand of shingle, it may take a different number of bundles to make a square. When cost comparing shingles, remember to base price on squares and not on bundles.
Metal roofing is typically sold by the sheet or panel. To determine the number of sheets or panels necessary to cover the roof, divide the width of the roof by the sheet or panel coverage width.
Other Roofing Materials
The basic square footage and length calculations detailed above should help estimate overall cost for other materials. Additional roofing materials that should be accounted for include items such as leak barrier, deck protection, drip edge, rake edge, ridge vents, and hip and ridge caps.
Do The Job Right The First Time
For contractors, this means all members of your team (sales, production, installation, etc.) and the homeowner can be on the same page when it comes to the roofing job. Resources can be allocated more efficiently and work can be completed on time and on budget.
How Does HOVER Work?
Our patented technology calculates square footage and linear measurements for the roof, siding, windows, trim and more. Just snap a few photos of the exterior of the house with the HOVER app and our patented technology will take it from there. Once the digital property is complete, you will receive detailed exterior measurements and an interactive 3D model to help homeowners design their projects. HOVER’s measurements are the basis for its accurate roofing calculator and will allow you to quote any job. Additionally, HOVER completely eliminates the need to re-measure for roofing projects.
