Solar Structural Inspections

Large commercial solar systems add significant load to the roof they are installed on. To be sure your roof is structurally safe with your designed solar system installed, we provide an inspection and certification service which verifies that the wind and weight load of your solar system will not exceed the structural capability of your roof.



When solar is installed on a roof, it adds two types of loads to the roof:

  • Dead loads are added by the weight of the panels
  • Live loads are added when wind pushes up against the panel from underneath

Understanding the implications of both of these loads on a roof is critical to verifying that your roof is going to stay safe with a new solar system installed.

Our structural inspections encompass:

  • Building heights and angles and their effect on wind
  • Rafter and purlin strength
  • Bridging and overlapping members
  • Roof sheet types
  • Corrosion
  • Heavy objects already installed in or on the roof

We provide the right data to our engineers along with photo verification to ensure that your roof is safe and prepared for solar.


Engineering Certification

With an inspection in hand, our strategic partner structural engineers are able to determine whether or not your roof has adequate strength when the additional weight and wind is applied.

If your solar system is too large to be safe on your roof, the maximum amount of solar that can be safely installed is calculated and provided as an alternative.
