When you’re hiring a roofing contractor, one of the most important things you can do is verify that they’re properly licensed and insured. Unfortunately, many homeowners assume a contractor is legitimate simply because they have a truck, a website, or a low price. In reality, those things don’t tell you much about whether you’re protected if something goes wrong.
After more than 16 years in the roofing industry, I’ve seen homeowners hire contractors who disappeared after collecting deposits, carried expired insurance, used uninsured subcontractors, or were never properly registered to perform work in the area. The result is often costly repairs, denied insurance claims, warranty problems, and thousands of dollars in unexpected expenses.
Here’s how to properly verify a roofing contractor before signing a contract.
Why Licensing and Insurance Matter
A roof replacement is one of the largest investments most homeowners make in their property. If a contractor is not properly licensed or insured, the risk often falls on the homeowner.
Potential problems include:
- Property damage during construction
- Injuries to workers on your property
- Incomplete projects
- Building code violations
- Failed inspections
- Warranty issues
- Difficulty selling your home later
The contractor’s credentials are not just paperwork. They are part of your protection.
Step 1: Ask for Proof of Insurance
Never accept a verbal statement that a contractor is insured.
Ask for certificates showing:
General Liability Insurance
This protects your home if the contractor accidentally damages your property during the project.
Examples include:
- Broken windows
- Damaged siding
- Damage to landscaping
- Interior water damage caused during construction
Workers’ Compensation Insurance
This protects workers who are injured while working on your property.
Without workers’ compensation coverage, injured workers may attempt to recover damages through the homeowner’s insurance or legal system.
Always request a current certificate directly from the contractor.
Step 2: Verify the Insurance Is Active
One of the biggest mistakes homeowners make is assuming that a certificate automatically means the policy is active.
Insurance policies can lapse due to:
- Non-payment
- Cancellation
- Expiration
- Coverage restrictions
Ask the contractor for a current certificate and verify the effective dates.
A professional contractor should have no issue providing this documentation.
Step 3: Check Local Licensing Requirements
Licensing requirements vary by state and municipality.
Many homeowners are surprised to learn that roofing licenses are not handled the same way everywhere.
Some areas require:
- State licenses
- City licenses
- County registrations
- Specialty contractor registrations
A reputable contractor should know exactly what is required for your area and be able to explain it clearly.
If a contractor becomes defensive when asked about licensing, consider it a warning sign.
Step 4: Verify Their Business Information
A legitimate roofing company should have:
- A registered business entity
- A physical business address
- A business phone number
- A professional website
- Online reviews
- A track record in the community
Be cautious of contractors who:
- Only provide a cell phone number
- Operate from temporary addresses
- Cannot provide references
- Recently changed company names
- Appear only after storms
Storm chasers often move from market to market and may not be available if warranty issues arise later.
Step 5: Ask Who Will Actually Perform the Work
Many homeowners never ask this question.
Some contractors sell the project and then hand it off entirely to subcontractors.
Ask:
- Are crews employees or subcontractors?
- Are subcontractors insured?
- Who supervises the project?
- Who handles warranty service?
The answer will tell you a lot about how the company operates.
Step 6: Verify Manufacturer Certifications
Manufacturer certifications are not the same as licensing, but they can be an additional trust signal.
For example, Colorado Pro Roofing is a GAF Certified Contractor.
These programs typically require contractors to meet installation standards and maintain certain qualifications.
However, certifications should never replace verifying licensing and insurance.
A contractor should have both.
Step 7: Review the Contract Carefully
A professional roofing contract should clearly identify:
- Contractor name
- Business address
- Scope of work
- Materials being installed
- Payment schedule
- Warranty information
- Insurance information
Avoid contractors who:
- Request large cash payments
- Refuse written contracts
- Leave important details blank
- Pressure you to sign immediately
Step 8: Be Careful After Major Storms
This is when many homeowners are targeted by unqualified contractors.
After hail storms, homeowners often hear:
“We have crews already in the neighborhood.”
“We can waive your deductible.”
“We only need your insurance check.”
These statements should raise concerns.
In Colorado, waiving insurance deductibles is prohibited under Colorado law. A reputable contractor should explain the process honestly and help homeowners remain compliant.
Common Red Flags
Over the years, I’ve noticed the same warning signs repeatedly.
Watch for contractors who:
- Cannot provide insurance certificates
- Avoid questions about licensing
- Use high-pressure sales tactics
- Offer unusually low pricing
- Demand large deposits upfront
- Have no local presence
- Have little or no online history
- Promise to cover insurance deductibles
- Refuse to provide references
If something feels off, trust your instincts and continue interviewing contractors.
My Professional Opinion
One of the biggest misconceptions homeowners have is believing that the lowest bid represents the best value.
In roofing, the cheapest proposal is often missing something.
It may exclude:
- Proper ventilation
- Synthetic underlayment
- Ice and water barrier
- Code-required materials
- Permit costs
- Insurance coverage
- Warranty protection
A quality roofing contractor should be transparent about what is included and willing to answer every question you have.
If a contractor becomes irritated when you ask for proof of licensing or insurance, that’s usually a sign to keep looking.
Professional contractors expect these questions and appreciate homeowners who do their homework.
Final Checklist Before Hiring a Roofer
Before signing a contract, verify that your roofing contractor can provide:
✓ Current general liability insurance
✓ Current workers’ compensation insurance
✓ Required local licenses or registrations
✓ Written estimate
✓ Written contract
✓ Local references
✓ Physical business presence
✓ Manufacturer certifications (if applicable)
✓ Clear warranty information
✓ Proof of experience
Doing these simple checks can help you avoid costly mistakes and dramatically increase the likelihood of a successful roofing project.
A reputable contractor will never be offended by these questions. In fact, they should encourage them.
