When it’s time to repair or replace your roof, hiring the right contractor matters more than you might realize. A roof protects your entire home, and hiring someone without the proper qualifications can lead to expensive mistakes, safety issues, and even legal headaches. This guide breaks down exactly what you should look for in a roofing contractor’s credentials—so you can hire with confidence and avoid the most common pitfalls.
Why Roofing Credentials Matter
A good roofing contractor isn’t just someone who knows how to install shingles. They’re licensed, insured, certified, and backed by the proper paperwork to protect you, your home, and your investment.
Safety
Roofing work is dangerous. If a worker gets hurt and the contractor doesn’t have the right insurance, you could be liable.
Quality
Credentials prove your roofer has met professional standards—not just watched a few YouTube videos.
Legality
In Washington, roofers must be licensed and registered with the state. If they’re not, they’re not legally allowed to do the job.
How to Know If a Roofing Contractor Is Legit
1. Business License & Registration
In Washington State, you can check a roofer’s license on the Department of Labor & Industries website. Make sure the name they give you matches what you find online—word for word.
2. Proof of Insurance
Every roofer should carry general liability insurance, which covers property damage, and workers’ compensation insurance for injuries on the job. Ask for copies and verify with their insurance company if you’re unsure.
3. Consistent Branding
Is their company name the same on their quote, website, truck, and contracts? If not, that’s a red flag. Some low-quality contractors change names to hide poor reviews or past complaints.
4. Strong Online Reviews
Check Google, Yelp, the BBB, and local directories. You’re not just looking for five stars—you want details that show they’re professional, punctual, and stand behind their work.
The Credentials Every Roofing Contractor Should Have
A good roofing company will gladly provide documentation for a state license through the Department of Labor and Industries, bonding, (which are required in Washington state) and insurance. Keep a special eye on the insurance, as working with an uninsured contractor can be disastrous.
Certifications from Roofing Manufacturers
Also, though they’re not required for your safety, look for credentials from top roofing system brands like GAF Master Elite, as they indicate above average quality and trustworthiness.
The Best Roofing Certifications to Look For
What Makes a Roofer ‘Certified’?
Certified roofers have gone through training directly with manufacturers, so they know how to install specific roofing systems the right way.
Top Certifications That Matter
- GAF Master Elite: Proven installation quality and strong customer satisfaction ratings.
- CertainTeed SELECT ShingleMaster: Advanced product and safety training.
- NRCA Membership: Shows the contractor is committed to staying up-to-date with industry best practices.
Watch out for vague claims like “factory-certified” with no mention of who certified them. If they won’t tell you, that’s your sign to move on.
How to Double-Check Their Credentials
Even if they give you all the right answers, take 10 minutes to do your own homework. Use Washington’s Contractor Lookup Tool, call the insurance company to confirm active coverage, or check that the company name and license match across all paperwork, trucks, and websites. It never hurts to be cautious, and the alternative just isn’t worth the risk.
What Should Be in the Roofing Contract
Before the work begins, you should get everything in writing, including:
- Their business license and contact info
- A detailed scope of work
- Roofing materials being used
- Start and finish dates
- Payment terms
- Warranty information
Tip: Avoid contractors who demand full payment upfront. A deposit is normal, but the rest should be tied to project milestones.
Must-Ask Questions for Any Roofing Contractor
Before you sign a contract, ask these questions:
- Are you licensed and insured in Washington?
- Can I see proof of your insurance and bond?
- Who will be managing the project day-to-day?
- Do you use subcontractors or in-house crews?
- What’s included in the warranty—for both materials and labor?
- What happens if unexpected repairs come up during the job?
A reputable roofing contractor won’t hesitate to answer these—and provide paperwork to back it up.
Why Local Experience and Reviews Matter
Choosing a locally owned roofing company comes with advantages that out-of-town contractors just can’t match. Roofers who regularly work in Western Washington understand which roofing materials perform best in the region’s wet, windy climate. They’re already familiar with local permitting processes, building codes, and even specific HOA requirements that can trip up someone unfamiliar with the area. And because they’ve likely completed projects in your neighborhood, it’s easier to find genuine reviews from nearby homeowners who can speak to their professionalism, punctuality, and the quality of their work.
Red Flags to Watch Out For
Avoid anyone who pressures you to sign today for a “limited-time deal,” doesn’t have a physical address or shows up in an unmarked truck, can’t show proof of insurance, or asks for full payment upfront. These are classic signs of a roofing scam or an unqualified contractor.
Final Thoughts
When you take the time to verify a contractor’s license, insurance, and certifications, you protect yourself from big risks and even bigger repair bills. The right credentials are your peace of mind—and your roof’s best defense.
