Short answer: a siding warranty is only as good as the board's ability to find it, prove it, and act on it years later — and on a community that may span multiple buildings and several board terms, that takes deliberate administration. After the crew leaves, the board's job is to know what coverage exists (separate manufacturer and workmanship warranties), make sure it's properly registered and documented, assign someone to track and file claims, and retain the records so a board five years from now can still use them. The warranty is a long-lived community asset; treated as paperwork to file and forget, it quietly becomes worthless. This guide is about the unglamorous, high-value work of keeping that coverage alive. Note: warranty terms are governed by the manufacturer's and contractor's actual documents — read them and, for any dispute, consult counsel.

Two different warranties, two different things
The most important distinction for a board is that a siding project produces two separate warranties that cover different things and are honored by different parties. The manufacturer's warranty covers the product itself — defects in the material and finish — and is backed by the manufacturer. The contractor's workmanship warranty covers the installation — whether the product was put on correctly — and is backed by the contractor. They have different terms, different proof requirements, and different claim paths, and a problem can fall under either. A board that conflates them ends up calling the wrong party. The first administrative act is simply to obtain both documents in writing and understand which covers what.
What the manufacturer warranty typically covers
For the fiber cement we install, James Hardie publishes a substrate warranty in the range of 30 years on the board itself and a separate ColorPlus finish warranty in the range of 15 years on factory-applied color, covering issues like peeling, cracking, chipping, and flaking within the stated terms and conditions. We state those figures qualitatively because the controlling numbers, conditions, exclusions, and proration are in James Hardie's actual warranty document — read it for the exact terms rather than relying on a summary. The practical takeaways for a board are that the product coverage is long-lived, that the finish and the substrate are covered separately and for different periods, and that coverage depends on the product having been installed and maintained per the manufacturer's instructions. We also install LP SmartSide, which carries its own separate manufacturer warranty with its own terms.
What workmanship warranties cover — and why they're separate
A manufacturer will not cover a leak caused by a botched flashing detail or an improperly fastened board — that's an installation issue, and it's where the contractor's workmanship warranty matters. Workmanship coverage is set by the contract, varies widely in length and scope, and is only as reliable as the contractor standing behind it. This is why, even for warranty purposes, the board's contractor selection has consequences long after the project ends: a workmanship warranty from a contractor who later disappears is of limited value. The board should get the workmanship terms in writing, understand the length and what triggers it, and weigh the contractor's durability as part of selection — our contractor evaluation checklist and questions to ask a siding contractor cover assessing that staying power.
Register, and register correctly
Manufacturer warranties commonly require registration or specific documentation to be fully effective, and a community that skips this step can find its long-term coverage weakened just when it's needed. The board should confirm what registration the manufacturer requires, ensure it's completed (often a contractor responsibility, but the board should verify it was actually done rather than assume), and keep proof of registration in the project file. Record the product line, the specific color, the install dates, and the buildings covered, since a multi-building community may have phases with different dates. Treat registration as a closeout deliverable the contractor must demonstrate, not a box someone hopefully checked. The manufacturer's resources spell out the registration requirements for their coverage.
Transferability matters for the community's future
Warranties can have rules about transferability — whether and how coverage passes to a subsequent owner — and for a community this cuts two ways. At the building level, the association itself is typically the long-term holder of common-element coverage, but individual owners selling units may benefit from transferable product coverage as a resale advantage, and there may be steps and time limits to preserve it. Because the rules are specific to each manufacturer's document, the board's job is to know them and communicate them, not to guess. Understanding transferability also helps the board explain to owners how the warranty supports property value over time — a point our cost of delaying replacement guide connects to marketability.
Decide who owns warranty administration
A warranty with no owner is a warranty no one will use. The board should explicitly assign warranty administration — commonly to the community manager, a designated board position, or a maintenance committee — so there is a named party responsible for knowing the coverage, spotting issues that may be warranty-eligible, filing claims correctly and on time, and keeping the file current. This matters most because boards turn over: the volunteer who managed the project may be gone in two years, and without an assigned, documented role the institutional knowledge leaves with them. Naming the role and writing down its responsibilities is what keeps the coverage from evaporating at the next election.
Manage claims methodically
When a potential warranty issue appears, the difference between a successful claim and a denied one is often documentation and timeliness. The administrator should first determine which warranty applies — product or workmanship — then follow that document's required process: notice within any time limits, the photos and records the warrantor requires, and the proof that the product was installed and maintained per specification. Keeping the original project file, the maintenance record, and the registration proof together makes this dramatically easier. Many denials trace not to a real exclusion but to missing documentation or a missed deadline, both of which good administration prevents. For disputes the warrantor won't honor, the board should involve counsel rather than handling it informally.
Retain records so future boards keep the coverage
Everything above fails if the records can't be found in year ten. The board should build a durable warranty file — manufacturer warranty documents, workmanship warranty, registration proof, product and color specifications, install dates by building, the contractor's contact and license details, and a maintenance log — and store it where it survives board turnover, ideally in the association's permanent records under the manager's stewardship rather than in a departing volunteer's email. Note any expiration or registration deadlines in the association calendar so they aren't missed. Community Associations Institute publishes guidance on association record retention; the principle is simple — a future board can only use coverage it can actually locate. This recordkeeping discipline mirrors the documentation posture in our board liability and deferred maintenance guide.
Manufacturer versus workmanship warranty — what a board tracks
| Aspect | Manufacturer warranty | Workmanship warranty |
|---|---|---|
| Covers | Product and factory finish defects | Installation — was it done correctly |
| Backed by | The manufacturer | The contractor |
| Typical length | Long-lived (e.g. ~30-yr substrate / ~15-yr finish) | Set by contract; varies widely |
| Key risk | Lapsed registration or maintenance terms | Contractor no longer in business |
| Board's job | Register, document, read the terms | Get terms in writing; vet contractor durability |
Key takeaways
- A siding project produces two separate warranties: manufacturer (product) and contractor (workmanship).
- Hardie coverage runs roughly 30 years on the substrate and 15 years on ColorPlus finish — read the actual document for exact terms.
- Manufacturer coverage typically depends on installation and maintenance per the manufacturer's instructions.
- Confirm and verify registration as a project closeout deliverable, and keep proof in the file.
- Know the transferability rules — they affect common-element coverage and owners' resale advantage.
- Assign a named owner of warranty administration so coverage survives board turnover.
- Manage claims by the document's process and deadlines; most denials trace to missing records or missed timing.
- Retain a durable warranty file in the association's permanent records, not a departing volunteer's inbox.
FAQ
Quick Answers
At least two that work differently: the manufacturer's warranty on the product and finish, backed by the manufacturer, and the contractor's workmanship warranty on the installation, backed by the contractor. They cover different problems and have different claim paths, so the first step is getting both in writing and knowing which covers what.
Generally on the order of 30 years for the substrate and 15 years for the ColorPlus factory finish (covering issues like peeling, cracking, and chipping within terms), but the controlling numbers, conditions, exclusions, and proration are in James Hardie's actual warranty document. Read it for the exact terms rather than relying on a summary.
Usually not under the manufacturer's warranty — that's an installation issue covered by the contractor's workmanship warranty, if one exists and the contractor is still around. This split is exactly why both warranties matter and why a contractor's durability is part of warranty value, not just price.
Often, yes — many manufacturer warranties require registration or specific documentation to be fully effective. Confirm the requirement, verify it was actually completed (don't assume the contractor did it), and keep proof in the project file. Treat it as a closeout deliverable, not an optional step.
Assign it explicitly — commonly the community manager, a designated board position, or a maintenance committee. Boards turn over, so without a named, documented role the warranty knowledge leaves with the volunteer who managed the project, and the coverage effectively goes unused.
A durable file: manufacturer and workmanship warranty documents, registration proof, product and color specs, install dates by building, the contractor's contact and license, and a maintenance log — stored in the association's permanent records under the manager, not a departing volunteer's email. Note any deadlines on the association calendar.
First make sure the claim followed the document's required process, deadlines, and documentation, since most denials trace to those rather than a true exclusion. If it was filed correctly and still denied, involve association counsel rather than handling a dispute informally. This is general information, not legal advice.
