Like with any construction project, we confirm the dimensions and utility requirements for your system’s size; however, supplies and required upgrades can affect the process. If a price change for your Tesla Solar Roof happens, our Phoenix Promise includes transparency and honesty at all times. So if there is a change of any kind, we will always notify you. We never perform work without both homeowners’ explicit permission. If a price change for the Tesla Solar Roof occurs, we will have updated paperwork to be signed and you will be involved in every step of the process. As always, if you have any questions or concerns, you can contact us for more information.
