If non-Tesla components (underlayments, vents, flashings) are substituted during repairs, does the roof lose its listing—how are AHJs verifying assembly conformity in the field?
Yes, substituting non-Tesla components (like underlayments, vents, or flashings) during repairs can void the Tesla Solar Roof’s UL listing and warranty, since it’s certified as a complete assembly.
AHJs (inspectors) verify conformity by:
-
Checking labels, permits, and product data
-
Comparing field installation to approved plans
-
Requiring Tesla-approved parts for final sign-off
Unapproved changes can cause inspection failures, warranty loss, or insurance issues.
Using other company’s parts, like vents or flashings, that Tesla didn’t make or approve can change the roof’s safety rating. Tesla tests its Solar Roof as one whole thing, so changing parts could cause fire safety or code problems. When inspectors check things out, they look at the plans, labels, and Tesla’s directions to be sure everything’s the same. If they see something that’s not right, they might not sign off on the work. So, to keep everything safe, it’s a good idea to use only Tesla-approved parts, or ask Tesla and your local inspector before you change anything.
To ensure compliance and safety, consider the following:
-
Consult Tesla Documentation: Review Tesla’s documentation and guidelines for repairs and replacements.
-
Work with Certified Installers: Engage with certified Tesla installers who are familiar with the system’s requirements.
-
AHJ Consultation: Consult with local AHJs to determine specific requirements and inspection procedures.
