Insurance Claims & Adjuster Disputes
When a damaged shingle is discontinued, a partial repair cannot restore uniform appearance. An ITEL laboratory analysis is how that becomes evidence rather than opinion.

You submit a physical sample. The lab reports the manufacturer and product line where identifiable, whether it remains in production, and the nearest current match with a comparison of colour and profile.
A finding of “no longer manufactured, closest match differs in colour and granule blend” is the sentence that carries the argument. It converts a matching dispute from aesthetic preference to documented unavailability.

Do not stop at the report. Physically obtain the proposed match, hold it against the existing roof in daylight, and photograph it from close range and from the street. A laboratory finding plus a photograph of the actual mismatch is far stronger than either alone.
Ohio’s administrative code speaks to restoring a reasonably comparable appearance. Where a jurisdiction has no such provision, the policy language on restoring the property to its pre-loss condition carries the same weight.
Often the carrier will order it. If not, the cost is small relative to the scope it decides, and it can be submitted as a claim expense.
Then the matching argument weakens and the conversation moves to whether the match is acceptable in place. The field test still matters.
Yes, and it works even more often, because siding profiles are discontinued faster than shingles.
