How to Choose a Licensed Roofing Contractor: A Homeowner's Guide

A roof replacement is one of the most significant home improvement investments you'll make — typically $8,000–$25,000 depending on size, pitch, and materials. Getting it right means choosing a contractor who will be around in 5 years when you need a warranty claim honored, and whose work meets local building code.

Step 1: Start with Licensing and Insurance

Roofing contractor licensing requirements vary dramatically by state:

• Florida: State Certified Roofing Contractor (CCC) license from FL DBPR — mandatory statewide, verify at myfloridalicense.com
• California: C-39 Roofing Contractor license from CA CSLB — verify at cslb.ca.gov
• NJ/NY/CT/MA: Home Improvement Contractor (HIC) registration required; state-specific licensing boards
• Texas: No statewide roofing license — but local permits are required and municipal registration is common in major cities

Regardless of state, every contractor should provide:

• General liability insurance (minimum $1,000,000 per occurrence) — protects you if they damage your property
• Workers' compensation insurance — protects you if a worker is injured on your property without it, you may be liable
• Request certificates of insurance naming you as additionally insured — this protects you if their insurer disputes a claim

Step 2: Get Three Quotes

A written, itemized quote should specify:

• Exact shingle brand, product name, and warranty level being installed
• Underlayment type (synthetic or felt, with specific product name)
• Ice and water shield coverage (minimum 6 feet from eaves in cold climates; full coverage for low-slope areas)
• Flashing: new metal flashing or re-using existing? All penetrations (chimneys, skylights, vents) should be re-flashed
• Decking: what happens if damaged decking is found? What is the cost per sheet?
• Cleanup and disposal of old shingles — included or extra?
• Permit: will the contractor pull a permit? (answer should always be yes)

Step 3: Verify Manufacturer Certification

Major shingle manufacturers (GAF, Owens Corning, CertainTeed, Atlas) have contractor certification programs:

• GAF Master Elite: Top 3% of roofing contractors nationally — requires licensing, insurance, and training. Enables GAF's longest system warranties (Golden Pledge — 50 years).
• Owens Corning Preferred or Platinum Preferred: Installer training and insurance verification; Platinum enables 50-year Total Protection warranty
• CertainTeed SELECT ShingleMaster or SureStart PLUS: Similar program with extended warranty options

Using a certified contractor unlocks significantly better warranty terms — standard contractor warranties run 10–25 years, while certified contractor warranties can run 50 years on the system (materials + installation labor).
