Tesla Solar Roof Site inspections are performed in conjunction with local city or county authorities. After the installation is completed is when inspections are typically performed, but in some cases inspections are conducted throughout the installation processes. Our crews and experts will typically handle the additional inspections; however, if attic access is required, we will always schedule the inspection on your schedule to make it convenient for you. We do require that someone 18 years of age or older to be available at the home for the final inspection. Tesla Solar Roof inspection times vary, but the average time can be up to 30 minutes, sometimes longer. As always, if you have any questions or concerns, please feel free to reach out to us.
