While solar panels shouldn’t damage your roof, they can in the very rare case that they’re installed incorrectly.

For most people experiencing solar panel problems, the issue is as simple as incorrect wiring, dirty materials, or reduced panel efficiency. In the case of panels that cause leaking, however, the problem can be a bit deeper.

Since well-installed solar panels should never cause a roof to leak, the culprit here is typically incorrect installation or shoddy workmanship. In both cases, the leak can usually be fixed but might be more extensive than, say, resolving a wiring issue.

Because of this, it’s essential to look for a solar installer that offers an extensive warranty on their workmanship.
