All you need to calculate the roof pitch, is your roof’s footprint or your house ground dimensions (length and width), and the rise of your roof from it’s base (length of a median / bisect). This roof pitch calculator is based on the basic principles of geometry, and greatly simplifies the process of calculating roof size, my doing the complicated math for you.

How to use roof pitch calculator

First, you will need to measure your roof size from the ground: using a measuring tape, measure the ground dimensions of your home, from corner to corner. If your roof has overhangs, add their width to the ground dimensions – otherwise your roof are might be off by as much as few hundred square feet.

Once you have measured your roof, you will need to plug in your roof’s dimensions, where “width” is the gable side, which we will use to calculate the roof pitch and the roof size. Read our roof pitch guide to learn how you can measure the roof pitch off the ground (without climbing the ladder) as well as on the roof, using the level and tape measure.

In the fields “Rise” or “Roof Pitch” plug in ether number (whichever you derived from using our roof pitch guide).

If you use the roof rise, you can measure it on the gable side of your roof, off the ladder with a measuring tape by going from the ridge of your roof, to the virtual horizontal line which is the base of the roof.

Click the “calculate roof pitch” button and you will see the results, showing your roof pitch, angle, as well as roof size.

Roof Pitch Calculator Results:

First of all, this roof pitch calculator is limited to estimating roof area for rectangular shaped roofs only. If your home has an “L” or other shapes, the roof sizes will be off. In this case, we recommend you check out our roof measuring guide (will be posted soon). The calculator also calculates roof sizes for Gable Roof only. Other roof types will be added later.

The roof installation price for your size and pitch roof, is calculated at about $320 per square, and includes roof tear-off of 1 layer of shingles, and installation of new 30 years architectural asphalt shingles with Ice and Water and 30 pound felt underlayment. This price is averaged out and may not be the going rate in your state.

  1. For this to be truly useful, there should also be an input box for wall height instead of just assuming 8 feet.

  2. A good roofing contractor is honest, dependable, and properly calculates payments
    according to what job they did. Flat roofing has assumed more importance than ever.
    From the pros and cons described for the different types of roofing materials available, it is possible for one to make an informed decision
    on the kind of roofing material that will
    best suit the weather of the area, as well as the
    available budget.
