Solar panel installation can usually be accomplished without disturbing your existing roof, which is beneficial if the shingles or tiles are fairly new. However, if the roof is on its last legs, replace it before the new solar panels go up. Otherwise, you may have to take the panels off in a year or two when the roof reaches the end of its life.

3 Signs You Need a New Roof Before Installing Solar Panels

1. Stains in the Attic

Water stains or wet insulation in the attic is a sign of a leak in the roof. Leaks can be a result of storm damage or old shingles that can no longer keep the water out. If you find evidence of leaks or have been spending money on repairs, putting a new roof on the house before installing solar panels can be more cost-effective in the long run.

2. You Find Granules in the Gutter

Asphalt shingles are covered in tiny granules, which give them their rough texture. As they absorb moisture and ultraviolet light, these granules come off and usually accumulate in rain gutters. If your gutters have a layer of sand or there are deposits near the downspouts, you’ll likely need a new roof soon.

3. The Roof Is Old

Most asphalt shingles are designed to last 20 to 25 years, while metal can last up to 50 years or more. If your roof is nearing the end of its expected life span, replace it before going solar, even if you haven’t had many problems with it.
