Understand what’s included in a new roof warranty in Michigan. Learn the difference between manufacturer and workmanship coverage.
When you invest in a new roof, you’re not just paying for materials and labor — you’re also paying for peace of mind. That’s where warranties come in. But not all roof warranties are created equal, and understanding the fine print is key to protecting your investment.
Here’s what every Michigan homeowner should know before signing a roofing contract.
1. Two Main Types of Roof Warranties
Manufacturer Warranty
Covers defects in the roofing materials themselves.
- Length: Often 20–50 years depending on material type.
- Example: If shingles crack prematurely due to a manufacturing flaw, this warranty may cover replacement materials.
Workmanship Warranty
Provided by your roofing contractor, covering errors in installation.
- Length: Typically 2–10 years, but quality contractors may offer longer.
- Example: If improper flashing installation causes a leak, the contractor repairs it at no cost.
2. What’s Commonly Covered
- Premature material defects
- Installation errors (workmanship coverage)
- Certain types of wind damage (up to a speed limit)
- Algae and mildew growth (in some shingle lines)
3. What’s Usually NOT Covered
- Normal wear and tear
- Damage from improper maintenance
- Storm damage beyond specified limits
- Unauthorized repairs by another contractor
4. How to Keep Your Warranty Valid
- Regular Inspections: Most warranties require professional inspections every few years.
- Prompt Repairs: Address small issues before they become major.
- Follow Contractor Guidelines: Use approved materials and methods for any future repairs.
5. Why Choosing the Right Contractor Matters
Even the best warranty is useless if your contractor isn’t around to honor it. That’s why it’s important to choose a local, established roofing company with a strong track record.
