Can Solar Panel Installation Cause Roof Leaks?

Solar panels are usually attached to your roof with brackets that may require drilling into the decking. Each hole creates a potential entry point for water if the flashing or sealant fails. Over time, the rubber boots or sealant around those penetrations can crack, shrink, or pull away, letting rain seep into the attic or ceiling below.

Another common issue is when panels are installed over an already damaged roof. If the shingles are worn, cracked, or missing, the added weight and foot traffic from the installation can worsen the problem. Water can then travel along the roof deck and appear far from the actual panel location, making the leak harder to trace.

First, move furniture and valuables away from the affected area to avoid water damage. Place a bucket under any active drip and remove wet items if you can do so safely. Then, contact a roofing professional or the solar installer to inspect the mounting points and seals. Do not attempt to climb onto the roof yourself, especially if it is wet or steep.

If water has already soaked into your ceiling or walls, you may need help with drying and cleanup. Local water damage pros can assess the extent of the moisture and dry out the affected areas to prevent mold growth. They can also help you document the damage for your insurance claim, though coverage depends on your policy.

If you notice sagging drywall, large water stains, or a musty smell that won't go away, you likely have significant water intrusion. The longer water sits, the more damage it does to wood, insulation, and electrical systems. Acting quickly can save you from more costly repairs later.

Water damage pros can handle the cleanup, including removing wet drywall, drying out the structure, and treating any mold that may have started. They can also help you document the damage for your insurance company. Policies vary, and your insurer decides what is covered, so check your policy to understand your options.
