This document is the manufacturer rejecting or limiting spot repair as a method. CertainTeed’s technical position on what hail does to an asphalt shingle, and what its warranty does and does not cover afterwards.

Technical Information Sheet #130 — Hail Damage
Issued by CertainTeed. Published here complete — no summary standing in for the document, no email required.
Issued by CertainTeed. Held in this firm’s reference library; not published elsewhere. Homeowner-identifying details, where a letter was addressed to a particular property, are blacked out — nothing else is altered, and no operative text is ever redacted.
What to do with it
Adjusters write "repairable" as though it were a finding. It is a conclusion, and this document is the manufacturer disagreeing with it. Building codes require installation to follow the manufacturer's instructions, which turns a technical bulletin into a compliance argument.
- 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.

CertainTeed discontinued product register
CertainTeed’s own master register of permanently discontinued and modified lines — the first place to look if your roof is CertainTeed.
CertainTeed Landmark and related lines
Even where the product name has not changed, CertainTeed identifies three conditions that defeat a partial repair on an aging roof: the older shingles have lost pliability, the granule blend has been reformulated, and lines such as Landmark converted from English to metric dimensions.
CertainTeed algae-resistant vs. non-AR
Mixing AR and non-AR shingles produces two defects: an immediate colour difference, and a slower one as algae grows on only half the roof.
CertainTeed roof repair guidelines
CertainTeed’s own repair standard rejects reusing shingles and forbids intermixing metric and English (standard) sizes on one roof. Building codes require installation to follow the manufacturer’s instructions — which makes this document a code argument, not just a preference.
CertainTeed Independence AR · Patriot AR
Independence AR and Patriot AR discontinued across the South Atlantic region excluding Alabama, plus colour deletions across Cedar Crest AR (Chaparral Cedar, Saddle Brown, Slate Gray) and Highland Slate AR (Saddle Brown).
CertainTeed Independence Designer
The manufacturer’s bulletin for a discontinued premium shake-look shingle — Shangle design, 300 lbs. per square, UL Class A, Class 1 impact rated. When the original product is gone, this is the specification a proposed substitute has to be measured against.
Other manufacturers saying the same thing
Atlas Chalet
The strongest document in this library. A carrier proposed fixing a Chalet roof by swapping in “comparable” shingles, or by cannibalising shingles from less visible slopes. Atlas’s Consumer Services Manager answered in writing — and the answer is no.
GAF Timberline HDZ
The obvious workaround — trim a modern shingle down to the old dimensions — is one GAF specifically rejects, because cut shingles may not seal to one another.
GAF storm-damaged shingle replacement
GAF’s formal position on storm damage. Hail, hurricane, tornado, microburst, ice damming and above-warranty winds are excluded from the shingle warranty — and because latent damage to the surrounding shingles is hard to assess, GAF’s own recommendation is replacement, not patching.
GAF storm-damaged shingle replacement
The earlier revision of the same bulletin, useful when the date of loss predates the 2021 version. It carries the same recommendation, and adds that shingles nailed through during tarping must be replaced.
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.
