# Roofer Warranty Pages: Two Warranties, and Homeowners Only Know One Source: https://rooferfindable.com/blog/2026-11-04-roofer-warranty-pages-manufacturer-workmanship.html Field guide November 4, 2026 A homeowner comparing two roof quotes sees 50 years on one proposal and 25 on the other and thinks she is comparing roofs. She is comparing shingle warranties, which cover defects in the material, while the warranty that covers the flashing, the nailing pattern, and the ventilation, the things that actually leak, comes from the roofer and might run 5 years or 10 or one. A warranty page that separates the two, in plain terms, does something rare in roofing: it makes the homeowner smarter than the next sales pitch. That is a page she bookmarks and a company she calls back. ## Name who honors each promise The manufacturer's warranty covers the product: shingles that crack, blister, or lose granules faster than they should because of how they were made. It is honored by the manufacturer, often prorated after an initial period, and frequently covers material only, not the labor to tear off and replace. The workmanship warranty covers the installation and is honored by the contractor, which is why it dies with the business if the business dies, a fact honest pages acknowledge by stating the term and the company's history. Registration is the detail that voids the story. Many manufacturer warranties require registration within a stated window after installation, often around 60 days, and enhanced system warranties add conditions: matching components, certified installers, sometimes an inspection. National Roofing Contractors Association guidance to homeowners makes the same point the FTC makes about warranties generally: read the terms, the exclusions, and the claim process before the work, not after the leak.

Improper installation voids material coverage too, which produces the ugly triangle where each warranty points at the other. A page that explains ventilation and installation standards up front is also a page pre-selling the scope that keeps both warranties alive. Storm damage belongs to insurance, not to either warranty, and saying so cleanly saves the worst phone call in roofing: the homeowner who believes hail is a warranty event. ## Put your workmanship term in numbers State the workmanship term, what it covers, how a claim is made, and whether it transfers to a buyer when the house sells, because transferability is a resale argument agents repeat. If your term is shorter than a rival's 25 year claim, explain what yours covers that a thin lifetime promise does not, in the specifics: labor included, leak response time, annual inspection included or not. The page's job is not to win the longest number contest. It is to be the explanation the homeowner uses to grade everyone else's numbers. ## Frequently asked questions ### What is the difference between a material and a workmanship warranty? The material warranty comes from the manufacturer and covers defects in the shingles themselves, usually material cost only and often prorated over time. The workmanship warranty comes from your roofer and covers installation errors like bad flashing or nailing. Most leaks are installation issues, so the second one matters more day to day. ### Does a lifetime shingle warranty mean my roof is covered for life? No. Lifetime is a term defined in the warranty document, tied to the product's expected service life and usually prorated, with exclusions for installation and ventilation problems. Read what the remedy actually pays, and for how long at full value, before weighing the number in a quote. ### Can a manufacturer deny a claim because of ventilation? Yes. Inadequate attic ventilation is a standard exclusion, since trapped heat and moisture age shingles prematurely. A roofer who checks and corrects ventilation during installation is protecting the material warranty as well as the roof. ### Should I register my shingle warranty? Yes, within the window the manufacturer states, often about 60 days after installation. Some enhanced warranties are unavailable or reduced without registration. Confirm whether your roofer registered it or handed you the paperwork, and keep the document with the house records.
