  1. Get a compass or compass app for your smartphone.  For the Android there is an app called “GPS Status”.  The iPhone may have a built-in app or you can get the “Digital Compass Free” app.  Some apps include a gyroscope if you want to measure the tilt of your roof.

  2. Use your compass within your home to determine which walls are closest to facing South or Southwest or Southeast. 

  3. Find a drawing of your home layout including square footage.  This is typically included in a home appraisal.  You will need to break out the square footage under each roof you have.

  4. Take a look at your roof(s), for example on Zillow, and find out what roof types they are.

The fields with the red border are required.
