Should I Replace My Roof Before Installing Solar Panels?

Thanks to the growing environmental awareness of people across the country, solar roofing has gradually become a popular option among homeowners. However, with a lifespan of 25 to 30 years, solar panels are likely to outlast your current roofing system.

Typically, an average residential roof has a service life of approximately 20 years. If your roof is already near or halfway through the 20-year mark, it may be more cost-effective to replace your existing roof before installing the solar panels. This will save you from additional expenses and a more complicated process later on when your old roof needs a complete replacement. Here’s what you can expect when installing solar panels over different roofing materials.

Tile Roofing

Take extra care when installing solar panels on a tile roof. Drilling through the tiles can result in breakage, but there are other methods that your contractor can use to do the job. Make sure your contractor knows the proper way to deal with tile roofs.

Asphalt Roofing

Solar panel installation on an asphalt roof usually involves drilling, with the mounting hardware attached to the roof studs. If your asphalt roof is relatively new and in good condition, you have the option to put off roof replacement, especially since solar panels are known to add a layer of protection for asphalt shingles.

Standing Seam Metal Roofing

Since metal roofing has an average lifespan of 40 to 70 years, it’s often considered as the best match for solar panels. It’s also easier and quicker to install the panels on this type of roofing material, mainly because of seams can be used for mounting hardware.
