Normally, it is suggested that the roof be less than 15 years old if you decide to put solar panels on your roof. The reason for this is that home solar system will last for 20 years or more, so you should have that length of time left on your roof. If your roof needs to be replaced or repaired we can do that as part of the project. It’s suggested that you have that done prior to the solar system installation.
It is possible to do a roof replacement or repairs once you have installed solar but it can be quite time consuming. In most cases, the panels would need to be moved or removed causing a partial re-installation of the panels and a loss of energy generation during that time. For those reasons, those in need of a new roof are recommended to get it done before or as part of the solar install.
