Roofing Warranties Explained: What's Actually Covered?

Robert ChenJanuary 3, 20269 min

Roofing warranties are confusing - full of fine print and exclusions. Here's what's actually covered.

Types of Warranties

Manufacturer's Material Warranty

Covers manufacturing defects, not installation errors
Typically 25-30 years, but prorated after 10 years
Labor costs often NOT included

Workmanship Warranty

From contractor, covers installation errors
Usually 1-10 years
Only valid if contractor stays in business

Understanding Prorated Coverage

"30-year warranty" often means full coverage for 10 years, then you pay increasing percentages. A 15-year-old roof with defects might only get 50% coverage.

What's NOT Covered

Wind or hail damage (that's insurance)
Improper ventilation effects
Algae/moss growth
Normal color fading
Foot traffic damage

Frequently Asked Questions

How long does a roofing warranty actually cover me?

Most manufacturer warranties advertised as "25-30 years" provide full coverage for only the first 10 years. After that, coverage is prorated, meaning you pay a growing share of repair costs out of pocket. A roof with a defect at the 15-year mark, for example, may only receive 50% coverage under the warranty.

What is the difference between a manufacturer warranty and a workmanship warranty?

A manufacturer warranty covers defects in the roofing materials themselves and typically runs 25-30 years, though often excludes labor costs. A workmanship warranty comes from your contractor and covers installation errors. Workmanship warranties usually last 1-10 years and are only enforceable while that contractor remains in business.

Does a roofing warranty cover hail or wind damage?

No. Neither manufacturer warranties nor workmanship warranties cover wind or hail damage. Storm damage is a homeowner's insurance claim, not a warranty claim. Warranties are limited to manufacturing defects and, in the case of workmanship warranties, installation errors.

What else is excluded from a standard roofing warranty?

Standard roofing warranties exclude damage from improper ventilation, algae or moss growth, normal color fading, and foot traffic damage. These exclusions are common fine print that homeowners often miss. If any of these conditions caused your roof to fail, neither your manufacturer nor your contractor is obligated to cover the repair.

What happens to my workmanship warranty if my contractor goes out of business?

If your contractor closes or goes out of business, the workmanship warranty is effectively void — there is no company left to honor it. This is a real risk with smaller contractors. Before hiring, confirm the company has an established track record and ask whether their warranty is backed by any third-party guarantee.
