5 Signs You Need to Replace the Roof Under Your Solar Panels

Your roof is the foundation for your solar investment, and ignoring early warning signs can lead to costly problems down the road. Here are five signs it’s time to consider replacing the roof under your panels:

1. Visible Sagging or Structural Issues

A sagging roof deck can compromise both your home and your solar system. Structural integrity should be addressed before any reinstallation.

2. Shingle Curling, Cracking, or Missing Sections

These are clear indicators of wear. Once panels are in place, repairs become more difficult and expensive.

3. Frequent Roof Leaks

Leaks can damage both your home and your solar equipment. It’s far better to replace your roof now than to deal with water damage later.

4. Roof Age Over 15–20 Years

If your roof is approaching the end of its lifespan, replacing it during an R&R will save you the cost and hassle of another removal in a few years.

5. Deteriorating Underlayment

The protective layer beneath shingles often wears out before the visible surface. Once compromised, leaks and structural issues follow.

A solid roof ensures your solar panels perform optimally for decades. If you suspect yours is aging, SLM Solar can help assess and coordinate your reroof and reinstallation.
