Path-Q Solar
How should a landlord assess solar suitability when a commercial roof is subject to a manufacturer's remaining warranty?
Answer
Confirm in writing whether the proposed solar work is permitted under the roof warranty and what conditions preserve coverage. The landlord should coordinate the solar design with the roof manufacturer or an authorized roofing contractor, document approved attachment and flashing methods, and compare the remaining warranty period with the expected solar service life and future reroofing plan.
Key points
- Review the warranty scope, exclusions, maintenance obligations, and transfer requirements.
- Identify whether penetrations, ballast, racking, pathways, or third-party work require approval.
- Require qualified roofing involvement where the warranty demands it.
- Plan for roof repairs, access, removal, and reinstallation if reroofing may occur during the solar term.
What it depends on
- Warranty language and remaining term
- Roof construction, condition, and attachment method
- Manufacturer and authorized-contractor requirements
- Solar term, expected service life, and reroofing schedule
Risks and trade-offs
- Unapproved work can narrow or void warranty protection.
- Preserving the warranty may increase installation cost or limit system layout.
- Removing and reinstalling solar for roof work can create substantial future cost and downtime.
Information you may need
- Complete roof warranty and maintenance records
- Roof drawings, age, condition, and inspection report
