Roof Complexity

Your roof’s complexity will determine your Solar Roof installation’s level of difficulty, which is factored into your final purchase price. Roofs fall into three tiers of complexity — simple, intermediate and complex. Roof complexity is determined by the number and severity of roof obstructions such as the pitch, number of joints, chimneys and other features on your roof that add to the difficulty of the installation.

Complexity Tiers

The lists below include general factors considered when determining your roof’s level of complexity. Your roof may not contain every feature of any one tier. Once you place a Solar Roof order, we will determine the level of complexity that best applies to your roof.


  • Single-level roof
  • Uncrowded mounting planes
  • Few obstructions (pipes, chimneys, skylights)
  • Low pitch


  • Multi-level roof (roof sections built on multiple stories of your house)
  • More crowded mounting plane
  • More obstructions (pipes, chimneys, skylights)
  • Higher pitch


  • Multi-level roof (roof sections built on multiple stories of your house)
  • Heavily crowded mounting plane
  • Many obstructions (pipes, chimneys, skylights)
  • Steep pitch

Customized to Your Roof

Once your Solar Roof order is placed, you will need to upload a recent utility bill so we can determine the right amount of solar for your roof. We will also schedule a site visit to review your roof and confirm its size and complexity before designing your system to meet your needs.
