Roof Warranties Decoded: Manufacturer vs Workmanship, and the Fine Print That Bites

Two different warranties cover every new roof, they cover different failures, and the gap between them is where homeowners get burned. Here's the decoder ring.

Manufacturer warranty: the materials

Covers manufacturing defects in the shingles or components themselves — and true factory defects are rare. Notes from the fine print: 'lifetime' typically means as long as you own the home, with full coverage only for an initial period before prorating begins; many warranties require registration within a window after install; and enhanced 'system' warranties only apply when the full component lineup (starter, underlayment, ridge, ventilation) is one brand, installed by credentialed contractors.

Workmanship warranty: the installation

Covers how the roof was put on — and installation error, not material defect, causes the overwhelming majority of young-roof leaks: flashing details, nailing patterns, valley work, penetrations. This warranty is only as good as the company standing behind it, which is why the door-knocker with no local address offering '10-year workmanship' is offering paper, not protection. Ares backs every job with a written workmanship warranty, and we're 20 minutes away when you call it in.

What quietly voids coverage

• ▸Pressure washing the roof.
• ▸Unrelated trades doing damage — satellite mounts through shingles are a classic.
• ▸Poor attic ventilation: manufacturers CAN and do cite it to deny shingle claims.
• ▸Layering over old shingles, coatings, or unapproved repairs with mismatched materials.

Questions that separate real coverage from sales talk

1. Who registers the manufacturer warranty, and will I get the confirmation? (We do, and you will.)
2. What exactly does your workmanship warranty cover, in writing, for how long?
3. Are you certified with this manufacturer, and does that unlock the enhanced warranty tier?
4. If a leak shows up in year three, what's the actual process — who do I call, what does it cost?
