With the new tax incentives for energy efficient home improvements like solar panels, more homeowners are again considering this as an option for their home. However, if your roof is more than a few years old, you may want to consider a roof replacement before a solar panel installation. If it is fairly new, you should get a roofing inspection.
Solar Panels Should Last 20 Years
Although brands and warranties vary, most solar panels have an expected life of about 20 years. A 3-tab shingle lasts a bit more than half that. Architectural shingles may last a bit more than 20 years. That means and older roof may need replacing before your solar does. If you end up needing a new roof, your solar company will need to remove and store the panels until the new roof is installed and then they’ll have to replace them. And you’ll end up paying for their time and services. You’ll also miss out on the benefits of the solar energy during that time. A roof replacement before a solar panel installation costs more now but will save you in the long run.
What a Roofing Company Looks for in a Roofing Inspection
Assuming you have architectural shingles and a relatively new roof, you shouldn’t need a roof replacement before the solar panel installation. However, you should get a roofing inspection. Your roofer will look at the area the panels are going on top for any issues. They can make repairs if they find an issue. Additionally, they will also look at your roof’s structure. Although solar panels only weigh about 4 pounds per square foot, it’s more about the potential uplift that may occur when strong winds get under the panels themselves. This is why a good solar installer installs the panels to the rafters and not the roof deck.
