3 Considerations for Roof Replacement With Solar Panels

Most roofs last between 20 and 25 years. Although there are exceptions, most solar panel systems need to be replaced every 20 years or so. For this reason, unless it is already in poor shape, most people do not replace their roofs before installing solar. 

What happens if a storm damages your roof or you start having roof issues earlier than expected? This can present a unique dilemma for homeowners who have invested a great deal of money in solar panels.  

Here are three things to consider if you need roof replacement with existing solar panels. 

1. Solar Panels Need to Be Removed

The first question people tend to ask when looking at roof replacement is whether their solar panels will need to be removed. The short answer is "yes," for two reasons. First, to give the roofing contractor full access to the roof to be replaced. Second, to eliminate the risk of damaging the panels or other components of the system.

The safest option is to have a professional completely remove them so that the roofing work can be completed. Contact your solar provider, who will already be knowledgeable about the safest and most efficient ways to remove and reattach the system. You can also have them coordinate this with your roofing contractor.

2. Consider Solar Upgrades

Another thing to consider when replacing your roof is whether it is a good opportunity to upgrade your solar system. Solar panels begin to lose effectiveness and efficiency over time. This depends on the type, but according to the National Renewable Energy Laboratories, the rate is less than 1 percent per yearduring the first several years of operation. 

If your solar panel system is less than five years old, it probably functions almost as well as when you first installed it. If it is older, the panels are likely degraded, and the rate of degradation only speeds up as the system ages. 

Keep in mind that the speed of innovations in solar technology is blistering. New and improved products are hitting the market every day. Even if you are not going to replace your entire system, a new roof installation may be a good opportunity to make some upgrades since you will already be paying the labor cost to remove and reinstall the solar system.  

3. Discuss Improvements With Your Roofing Company

The final thing to consider when replacing a roof with solar panels on it is to ask your roofing company about upgrades that could benefit the solar panel system. This could include improved supports on the structure of the roof or more seamless roof "penetrations." It might entail minor modifications that could make reinstalling the solar panels much easier.
