Roofing Calculator from HOVER Mobile App

A roofing calculator uses measurements of each roof plane to calculate the total square footage of the roof surface. Those numbers provide a basis for estimating how much roofing material will be needed when the contractor provides a quote for installation.

How to accurately calculate roofing

To calculate how much roofing is necessary for a house, there are several measurements that must be obtained. First, the total square footage of the roof’s surface must be estimated. The length and width of each plane on the roof, including dormers, should be measured. The perimeter length of the roof, valleys, ridges, chimneys, vent stacks, and skylights should also be noted. Finally, the slope – or pitch – of the roof must also be accurately measured.

Roofing materials

The purpose of calculating the precise measurements of a roof is to ensure that the appropriate amount of roofing materials are ordered. When the square footage of a roof is determined, you can then determine how much roofing is needed to cover it. For example, a “square” is an area which measures 100 square feet. To determine the number of squares on a particular roof, divide its total square feet by 100.

Shingles

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 bundles.

Metal Roofing

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 these items. Additional roofing materials that should be accounted for include items such as leak barrier, roof deck protection, drip edge, rake edge, ridge vents and hip and ridge caps.

Why use HOVER?

HOVER does more than just provide accurate measurements and drawings in the typical 2D format. It also lets contractors see and interact with measurements in 3D, allowing them to easily visualize specific dimensions. Plus, the 3D rendering allows you to design the project beforehand. HOVER can cut down on your time taking measurements on the jobsite and calculating quotes in the office. Roof measurements are then used to quote any roofing job and completely eliminate the need to re-measure.

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 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 lineal measurements for roof, siding, windows, trim and more. Just snap a few photos of the exterior of the house with the HOVER app and they’ll automatically upload to the cloud. Once the digital property is complete, you 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.
