Quick answer: Most residential roof warranties in metro Atlanta come in two layers — a manufacturer’s material warranty (typically 25–50 years, prorated after the first decade) and a workmanship/labor warranty from the installing contractor (ranging from 2 years to lifetime, depending on the installer’s certification tier). Storm damage, improper attic ventilation, and normal wear are usually excluded from manufacturer coverage but may be handled separately through homeowner’s insurance.
The Two Warranties Homeowners Confuse
When a roofing estimate mentions a “50-year warranty,” it’s almost never one single promise — it’s two separate contracts stacked on top of each other, and mixing them up is the single most common source of warranty disputes we see in Cobb County and across metro Atlanta.
1. Manufacturer’s material warranty. This covers defects in the shingles, underlayment, or flashing themselves — things like granule loss, cracking, or premature failure that isn’t caused by installation error, weather, or age. Standard warranties run 25–30 years; enhanced warranties (often requiring a full certified system of matching components) can extend to 50 years or lifetime, but coverage typically steps down to a prorated dollar amount after year 10.
2. Workmanship warranty. This is the contractor’s promise that the roof was installed correctly — flashing sealed, nailing pattern correct, ventilation properly balanced. This is where the installer’s certification level matters most. As a CertainTeed Master Shingle Applicator, LB Roofing & Construction can offer extended workmanship coverage on qualifying systems that goes well beyond the industry-standard 2-year labor warranty many contractors provide.
The gap between these two warranties is where most homeowner frustration happens: a manufacturer will deny a claim rooted in bad installation, and a contractor without proper certification can’t offer the enhanced coverage tier at all.
What Voids a Warranty (and What Doesn’t)
Warranties are conditional, not automatic. Common voiding events include: skipping required annual inspections on enhanced-tier warranties, allowing unlicensed contractors to perform repairs or add rooftop equipment (satellite dishes, solar mounts) without documentation, and inadequate attic ventilation that causes heat buildup and shingle degradation from underneath.
What does not void a warranty: normal hail or wind damage (that’s an insurance claim, not a warranty claim), age-related wear within the covered term, and manufacturer defects discovered during a routine inspection. Keeping dated photos, invoices, and inspection records is the best protection homeowners have if a claim is ever contested.

Frequently Asked Questions
Q: Does a roof warranty transfer if I sell my house?
A: Most manufacturer warranties are transferable one time to a new homeowner, usually within 60 days of closing and often for a small transfer fee — but the enhanced, longer-term warranty tiers may have stricter transfer windows, so check the specific paperwork before listing your home.
Q: Is storm damage covered under my roof warranty?
A: No — hail, wind, and falling debris damage are covered by homeowner’s insurance, not the manufacturer or workmanship warranty. Warranties cover defects and installation errors, not weather events.
Q: How do I know what warranty tier my roof actually has?
A: Check your original installation paperwork for the manufacturer’s certificate number and the contractor’s workmanship warranty document. If you can’t find either, a licensed roofer can often verify manufacturer coverage using the shingle batch and installation date.
