Can solar panels damage a roof or cause leaks?

Quick answer

The practical explanation

Any roof penetration or poorly handled flashing can create risk, but a properly planned mounting system should protect the roof and manage water. Existing roof condition, workmanship, attachment details, and later roof access all matter.

What to know

Three points to keep in mind

• Roof condition should be documented before installation.
• Mounting and waterproofing details should match the roof type.
• After severe weather or roof work, inspect accessible mounting and flashing areas.

For your home

A site-specific answer still matters

Solar results and service needs depend on the roof, equipment, shade, household electricity use, utility requirements, and the condition of the existing system. Use this guide as a starting point, then have the property and equipment evaluated before making a major decision.
