Roofing Warranties Explained: What Homeowners Need to Know

Understand the Difference Between Manufacturer and Workmanship Warranties

If you’re investing in a new roof, you want to be sure it’s protected — not just today, but for years to come. Roofing warranties can offer that peace of mind, but not all warranties are created equal.

Here’s what Quad Cities homeowners need to know about roofing warranties and how to ensure you’re covered.

Types of Roofing Warranties

1. Manufacturer’s Warranty (Material Warranty)

This is issued by the shingle manufacturer (like TAMKO or Owens Corning) and covers defects in the roofing material itself.

Common Features:

• Coverage ranges from 20 years to "lifetime"

• May be prorated after the first 10–15 years

• Only valid if the shingles were installed to the manufacturer’s specifications

Important Note: Improper installation can void your material warranty — that’s why choosing a certified contractor matters.

2. Workmanship Warranty (Labor Warranty)

This warranty comes from your roofing contractor and covers errors in installation. At Twin Bridge Roofing and Construction, we proudly stand behind our work with a lifetime workmanship warranty on full replacements.

What it covers:

• Leaks due to improper installation

• Misapplied flashing

• Fastener problems

• Premature shingle failure due to poor install

What it doesn’t cover:

• Storm damage

• Material failure (covered by manufacturer)

• Damage from third parties (trees, satellite dishes, etc.)

What to Watch Out For

❌ “Lifetime” Isn’t Always Lifetime

Many shingle warranties are prorated — meaning the value of your coverage decreases over time. Understand how long full coverage lasts and what the transfer terms are if you sell your home.

❌ Unlicensed Installers Can Void Your Warranty

Always verify that your contractor is licensed in your state. In Illinois and Iowa, roofing license numbers should be provided on your contract and your permit.

IL License #: 104.019411
IA License #: C137288
