Solar Roof Leaks and Installation Defects

A rooftop solar system can require dozens of roof penetrations. When flashing, mounting, or wiring is done poorly, homeowners may see leaks, rot, mold, ice dams, cracked shingles, and even structural damage, sometimes years later. Systems can also underperform or stop working because of design or installation problems. Muggeo & Associates represents homeowners in claims against solar installers, subcontractors, and manufacturers.

Common Installation Defects

Improperly flashed or sealed roof penetrations
Mounts lagged into sheathing instead of rafters
Panels installed on roofs that needed replacement first
Structural overloading without an engineering review
Damaged shingles and voided roof warranties
Wiring, conduit, and inverter installation errors
Ice dam and snow-load problems in New England winters
Missing permits or failed inspections

Damage That Follows a Leak

Water intrusion can lead to rot, insulation damage, and Mold and Water Damage. Document the damage quickly and stop further water entry. Your homeowners insurance may cover some resulting damage, but insurers often exclude faulty workmanship and seek reimbursement from the installer. See Insurance Coverage Disputes.

Frequently Asked Questions

Who pays if solar panels caused my roof to leak?

Usually the installer is responsible for penetrations and flashing it installed, under the contract and any workmanship warranty. Your homeowners insurer, the roofer, and the manufacturer may also be involved. Report the leak in writing right away.

Can I make the installer remove and reinstall panels to replace my roof?

Many contracts address removal and reinstallation, sometimes for a fee. If the installer caused the roof damage, the cost of removal, roof repair, and reinstallation may be part of your damages.

My system is producing much less than promised. What can I do?

Check whether the contract includes a production guarantee and how it is measured. Monitoring data, utility net metering statements, and an independent inspection can show whether the shortfall comes from equipment, design, shading, or installation.

How long do I have to bring a claim?

Contract claims in Massachusetts generally have a six-year limitations period, tort and Chapter 93A claims have shorter periods, and claims against builders for improvements to real property can be limited by a six-year statute of repose. Warranty notice deadlines may be shorter still.
