Roofing Square Calculator

If you’re replacing a roof, the first consideration needs to be the roof’s size so accurate material estimates can be made.

In the U.S., roofs are measured in square footage, and roofing contractors typically quote projects based on the size of the roof in squares. Consequently, gathering the size of the roof in squares and square footage is the first step.

Getting accurate roof measurements can be difficult but with our roofing calculator, you’ll be well prepared to take measurements of any roof. Whether you’re a contractor looking to train a new employee or a homeowner looking to do some renovations, you’ll find this guide helpful for any roofing project.

What’s your roof slope?

You will also need to know the slope of your deck. In order to determine this, measure the vertical rise of your deck in inches over a 12″ horizontal distance. If this rise is 4″, then your roof slope is 4 in 12.

Roof slopes are always expressed with the vertical rise mentioned first and the horizontal run (12″) mentioned second.

Roofing Calculator

With that as background, you are now ready to estimate how many shingles you will purchase for your roof project. This roof shingle calculator requires four basic inputs:

  • Roof length (measured in feet)
  • Roof width (measured in feet)
  • Roof pitch
  • Roof type (either gable or hip)

Using these four inputs, you will get several basic outputs:

  • Roof area (measured in sq ft)
  • Number of squares
  • Number of bundles
  • Approximate price (in dollars)

The estimate of a final price will depend, to a large degree, on the overall size of your home (i.e. sq footage). This makes sense, right? The bigger your roof area, the more shingles will be used to cover the footage of this area completely.

In addition, you will need to take into account the materials being used. If you are using standard asphalt shingles, your price will be lower than if you are using more expensive slate, metal or tile shingles. For most residential homes, asphalt shingles are the standard, but there are plenty of reasons to avoid using asphalt shingles as your material, such as if you are concerned about the waterproof coverage of your home.
