How to Find a Certified Roofer in Your Area

Why Certification Matters

Hiring an unqualified contractor can lead to poor workmanship, voided warranties, liability issues, and costly repairs down the road. Certified contractors have demonstrated their competence and commitment to quality through rigorous training and ongoing education.

Benefits of Hiring Certified Contractors

Better Warranties: Manufacturer-certified contractors can offer enhanced warranty coverage that uncertified contractors cannot.
Proper Installation: Certified installers are trained in manufacturer-specific installation techniques that ensure optimal performance.
Financial Protection: Licensed, insured contractors protect you from liability for accidents or property damage.
Recourse if Problems Arise: Certified contractors have accountability through licensing boards and manufacturer programs.

Certifications to Look For

State Licensing

Most states require roofing contractors to hold a license. Licensing requirements vary by state and may include exams, experience requirements, and financial responsibility (bonds).

Manufacturer Certifications

Major shingle manufacturers offer certification programs that verify contractor expertise with their products:

GAF Master Elite
Only 3% of contractors qualify. Requires proven reputation, proper licensing, insurance, and ongoing training. Offers the best GAF warranty options.
Owens Corning Preferred Contractor
Requires licensing, insurance, and commitment to customer service. Access to enhanced warranty options and marketing support.
CertainTeed SELECT ShingleMaster
Demonstrates expertise in CertainTeed installation. Requires ongoing training and adherence to quality standards.

Insurance Requirements

Verify contractors carry both:

General Liability Insurance: Covers property damage and injuries that occur during the project
Workers' Compensation: Covers worker injuries on your property (without this, you could be liable)

How to Verify Credentials

Step 1: Check State License

Visit your state's contractor licensing board website. Search by company name or license number to verify:

License is active and current
No unresolved complaints or disciplinary actions
Business name matches the license

Step 2: Verify Insurance

Request certificates of insurance directly from the contractor. Call the insurance company to confirm coverage is current. Make sure limits are adequate for your project.

Step 3: Confirm Manufacturer Certifications

Visit manufacturer websites to verify certification status:

Owens Corning: owenscorning.com/roofing/contractors
CertainTeed: certainteed.com/find-a-pro

Questions to Ask Contractors

A reputable contractor will welcome your questions. Here are the essential ones:

What is your license number, and can I verify it?
Any hesitation to provide this is a red flag.
Can you provide proof of insurance?
Request certificates for both liability and workers' comp.
What manufacturer certifications do you hold?
Affects warranty options available to you.
How long have you been in business?
Established companies are more likely to honor warranties.
Will you use subcontractors?
If so, are they also licensed and insured?
Can you provide references from similar recent projects?
Actually call these references and ask about their experience.
What warranty do you offer on workmanship?
This is separate from manufacturer material warranties.
What is your payment schedule?
Be wary of large upfront deposits. Never pay in full before work is complete.
How do you handle unexpected issues or change orders?
Understanding this prevents surprises during the project.
Will you obtain necessary permits?
Licensed contractors handle permitting as part of the job.

Red Flags to Avoid

Warning Signs of Untrustworthy Contractors

Door-to-door solicitation after storms: "Storm chasers" often do subpar work and disappear
Requiring large upfront payments: Standard is 10-30% deposit, not 50%+
Cash-only or no written contract: Always insist on documentation
Pressure to sign immediately: Legitimate contractors give you time to decide
No physical business address: P.O. boxes only can indicate fly-by-night operations
Unusually low bids: May indicate cutting corners on materials or labor
Unwilling to pull permits: May indicate they're not properly licensed
Negative reviews mentioning warranty disputes: Check multiple review sources

Comparing Estimates Effectively

When comparing estimates, don't just look at the bottom line. Compare:

Materials: Same brand, type, and quality level?
Scope of work: Does each estimate include the same tasks?
Warranties: Both workmanship and material warranties
Timeline: Is it realistic for the scope of work?
Payment terms: Deposit amount and payment schedule
