This document establishes that the product is no longer manufactured. Mastic/Ply Gem states in full capitals that any repair performed without prior written authorization from Ply Gem voids the warranty entirely. The identical all-caps clause appears in the Variform warranty (naming Variform), so the two Cornerstone Building Brands documents share this language.

In their own words
A color variance may occur between any new replacement panel in comparison to the originally installed panels due to weathering exposure and would not be indicative of defective Siding, Soffit and/or Accessories.

That sentence is not our characterisation of the manufacturer’s position. It is the manufacturer’s position, in the document below, which you can read yourself in about a minute.
The same document also establishes
Mastic/Ply Gem states in full capitals that any repair performed without prior written authorization from Ply Gem voids the warranty entirely. The identical all-caps clause appears in the Variform warranty (naming Variform), so the two Cornerstone Building Brands documents share this language.
“In the event of a discontinued Product, Alside may, at its sole discretion, provide the claimant with a refund to cover the cost of repairing or replacing the defective Products part or component.”
Alside's warranty is void where modifications, alterations or removal of parts are made without prior written authorization from Alside; unauthorized repairs that deviate from Alside guidelines also void coverage.
“This Warranty is void if any modifications, alterations, or removal of parts are made to the Products without prior written authorization from Alside.”

What to do with it
A carrier cannot direct you to buy something that is not sold. Once the product is off the market, the question stops being "can this be repaired" and becomes "can this building be restored with materials of like kind and quality" — which is a very different question, and one the carrier has to answer.
- You have the manufacturer’s document. That part is finished. Most homeowners never get this far, and it is the step a carrier cannot argue with — it is not your opinion, it is the company that made the product.
- Put it in writing, to the adjuster, with the claim number. Attach the document and ask one specific question: name the exact replacement product — manufacturer, line, colour, dimensions, exposure, nail zone, sealant design, supplier, quantity available locally — and who will answer for the repair if it fails. Vague answers are the whole game; a specific question ends it.
- Get the position on the record before anything gets installed. Once a mismatched or incompatible repair is on the building, you are arguing about something already done.
If you want the second and third steps handled by someone who does this for a living, that is what we are for — and the review costs nothing. If you would rather do it yourself, the document above is yours either way. That is the point of publishing it.

Alside vinyl windows
Alside (warranted by Associated Materials Innovations, a division of Associated Materials, LLC) states in its Windows and Patio Doors Lifetime Limited Warranty — applicable to products manufactured on or after March 1, 2025 — that replacement parts come only in the standard colour available at the time of the claim, that a colour variance versus the original due to weathering is expected and is not a defect, and that a discontinued product may be settled by refund rather than replacement.
Other manufacturers saying the same thing
Atlas Chalet
Atlas discontinued the Chalet 30-year laminated shingle in mid-2010 and replaced it with the Pinnacle HP line. Chalet went onto tens of thousands of Georgia homes, and it is the single most common discontinued-shingle dispute in this market.
Atlas Chalet
Atlas’s follow-up letter goes further than the discontinuation itself: the Chalet’s proprietary design and physical size differ from current production, so combining old and new raises ASTM compliance problems.
Atlas GlassMaster
Atlas Roofing Corporation confirms in writing that the GlassMaster shingle is no longer manufactured.
Atlas StormMaster Slate
Discontinued effective January 1, 2023. Atlas did not just retire the product — it stated on the record that nothing else in the market matches it.
The rule this document serves
Your policy promises repair or replacement with material of like kind and quality. That is a replacement-cost and indemnity obligation, not an appearance theory — and it is why “matching” is the carrier’s word, not the policy’s. Where the installed product cannot be bought, or cannot be combined with what is still sold, the covered building cannot be restored to like kind and quality by patching it, and that is true before anyone argues about how it looks. The full doctrine, and the other 125 documents, are on the discontinued materials hub.
You have the manufacturer's document. The next part is the argument. Handing a carrier a technical bulletin and getting it honoured are two different jobs. The case review is free, and you pay nothing unless we recover.
