Hiring a roofing contractor involves more than finding someone who can climb a ladder and install shingles. The roof is one of the most important parts of a home, and its installation or repair affects safety, energy efficiency, and long-term durability.
In 2025, many homeowners are asking: what certifications should a good roofing contractor have? This question matters because certifications can show whether a contractor meets industry standards, follows safety regulations, and stays informed about current roofing practices.
This article explains what roofing certifications are, how they work, and why they are used to evaluate contractor qualifications.
What Are Roofing Certifications And Why Do They Matter
A roofing certification is an official credential that shows a contractor has been trained and approved by a recognized manufacturer or industry organization. Some certifications also come in the form of roof certificates, which are documents confirming that a roof has been inspected and is in good condition for a specific period.
Licensing and certification are not the same. A license is issued by the state and is required by law in some locations. A certification is voluntary and usually provided by roofing product manufacturers or professional associations.
Roofing certifications help identify contractors who follow recommended installation practices, meet safety standards, and keep up with product changes. These credentials can help homeowners avoid hiring unqualified or inexperienced roofers.
Key benefits of hiring a certified roofer include:
- Quality Workmanship: Certified contractors demonstrate they can install roofing systems correctly
- Warranty Protection: Many manufacturers only honor warranties when certified installers do the work
- Safety Standards: Certified roofers typically follow industry safety protocols
Mandatory State Licensing Requirements For Roofing Contractors
A roofing contractor license is a legal credential issued by a state or local government. It allows a contractor to operate a roofing business within that region and confirms they meet the minimum legal standards for performing roofing work.
Licensing requirements vary by state, but they often include passing an exam, showing proof of work experience, and submitting to a background check. Some states also require liability insurance or bonding.
For example, Florida requires roofing contractors to pass both trade knowledge and business exams. California requires four years of journey-level experience. In Texas, there is no statewide roofing license, but contractors can pursue voluntary credentials such as the RCAT certification.
| What State Licenses Cover | What State Licenses Don’t Cover |
|---|---|
| Basic trade knowledge | Manufacturer-specific training |
| Legal authority to operate | Ongoing industry education |
| Insurance verification | Product warranty eligibility |
| Code compliance | Manufacturer approval |
A roof certificate differs from a state license. While a license permits legal operation, a roof certificate often validates specific skills or knowledge related to roofing materials or installation methods.
Essential Roofing Certifications From Leading Manufacturers
1. GAF Master Elite
The GAF Master Elite certification is earned by roofing contractors who meet specific criteria set by GAF, North America’s largest roofing manufacturer. To qualify, contractors must be properly licensed, adequately insured, have a proven reputation, and commit to ongoing professional training.
Only about 2% of all roofing contractors in the United States hold this credential. Homeowners who hire a Master Elite contractor can access enhanced warranties that cover both materials and workmanship for longer periods than standard warranties.
2. Owens Corning Platinum Contractor
The Owens Corning Platinum Contractor program recognizes roofers who complete product-specific training and maintain high standards for installation quality. These contractors must demonstrate consistent excellence in workmanship, customer service, and business practices.
Platinum Contractors can offer Owens Corning’s strongest warranty options, which include coverage for both materials and installation. This certification requires regular performance evaluations to maintain active status.
3. CertainTeed Select ShingleMaster
The Select ShingleMaster credential is CertainTeed’s highest level of roofer certification. To earn it, contractors must pass the Master Shingle Applicator test, carry proper insurance, and demonstrate ethical business practices.
This certification allows contractors to provide CertainTeed’s SureStart PLUS extended warranty coverage. Contractors with this credential have proven their knowledge of proper installation techniques for CertainTeed roofing products.
Safety Training And Insurance Requirements
1. OSHA 10-Hour Or 30-Hour
The OSHA safety courses teach roofing professionals how to identify, avoid, and prevent job hazards. The 10-hour course covers basic safety for workers, while the 30-hour version provides more comprehensive training for supervisors.
These programs cover critical safety topics including:
- Fall protection systems
- Ladder and scaffolding safety
- Personal protective equipment
- Hazard communication
When a roofing contractor has completed OSHA training, it shows they’ve received formal instruction in workplace safety. This training helps protect both workers and homeowners during roofing projects.
2. RCAT Certification
The Roofing Contractors Association of Texas (RCAT) certification is a voluntary credential program for Texas roofing professionals. To qualify, contractors must pass a business and safety knowledge exam, carry liability insurance, and have at least three years of roofing experience.
This certification is especially valuable in Texas, where there is no statewide licensing requirement for roofers. The RCAT roof certificate helps homeowners identify contractors who have voluntarily committed to industry standards and ethical practices.
RCAT certification requires annual renewal and ongoing education, ensuring that certified contractors stay current with industry developments and local building codes.
How To Verify A Roofing Contractor’s Credentials
1. Ask For License Numbers
When hiring a roofing contractor, ask for their license number and check it with your state’s licensing board. Most states maintain online databases where you can verify a contractor’s license status.
Warning signs that may indicate credential problems include:
- Reluctance to provide license information
- License numbers that don’t match official records
- Expired licenses or disciplinary actions
- Operating under multiple business names
2. Check Manufacturer Websites
Major roofing manufacturers maintain online directories of their certified contractors. These searchable databases allow homeowners to verify whether a contractor holds current certifications.
For example, GAF’s website lets you search for Master Elite contractors by location. Owens Corning and CertainTeed offer similar tools to find certified roofers in your area.
These directories are updated regularly, so a contractor claiming certification should appear in the appropriate manufacturer’s listing. If they don’t, their certification may have expired or been revoked.
3. Request Proof Of Insurance
A legitimate roofing contractor should readily provide proof of insurance coverage. Request certificates for both general liability insurance and workers’ compensation (if they have employees).
The insurance certificate should include:
- The contractor’s business name
- Policy numbers and coverage limits
- Effective dates and expiration dates
- Insurance carrier information
Current insurance documentation helps confirm a contractor meets industry standards and protects homeowners from liability for accidents or property damage during the project.
Benefits Of Working With A Certified Roofer
Certified roofers have demonstrated their commitment to quality and professional standards. Their credentials verify they’ve received specific training in proper installation techniques.
Working with a certified contractor typically provides several advantages:
- Extended Warranties: Certified roofers can offer manufacturer warranties with longer coverage periods
- Quality Materials: Access to premium roofing products that may not be available to non-certified contractors
- Proper Installation: Training in manufacturer-approved techniques that help prevent future problems
- Code Compliance: Knowledge of current building codes and regulations
The difference between certified and non-certified contractors becomes clear when comparing key features:
| Feature | Certified Roofer | Non-Certified Contractor |
|---|---|---|
| Warranty Options | Extended manufacturer coverage | Limited or basic coverage |
| Training | Verified product-specific training | Unverified experience |
| Installation Methods | Follows manufacturer specifications | May use non-standard methods |
| Material Access | Full product line availability | May be limited to basic products |
| Support Resources | Manufacturer technical assistance | Limited support options |
Emerging Trends In Roofing Certifications By 2025
The roofing industry continues to evolve, with new certification programs reflecting changes in technology and environmental awareness. Several trends are shaping roofing certifications in 2025:
Sustainable roofing certifications are growing in importance. These programs focus on environmentally responsible materials and installation practices that reduce waste and energy consumption. Contractors can now earn credentials specifically for green roofing systems, solar integration, and recycled materials.
Digital verification systems make checking certifications easier and more reliable. QR codes and online databases allow homeowners to instantly verify a contractor’s credentials, reducing the risk of fraud or misrepresentation.
Energy efficiency certifications have become increasingly valuable as homeowners seek ways to reduce utility costs. These programs train contractors to install roofing systems that improve insulation, reflect sunlight, and regulate temperature more effectively.
Smart home integration is creating new certification categories for contractors who can properly install or coordinate with solar shingles, roof-mounted sensors, and integrated ventilation systems.
New certification types gaining prominence include:
- Solar roofing installation certification
- Cool roof and reflective material certification
- Green roof system certification
- Integrated smart roof technology certification
Building Longevity And Security With Certified Roofing
Properly certified roofing contractors follow installation methods that maximize roof performance and lifespan. When materials are installed according to manufacturer specifications, they resist weather damage better and maintain their protective qualities longer.
Certified professionals evaluate the entire roofing system, including ventilation, underlayment, and flashing details. This comprehensive approach helps prevent common problems like leaks, ice dams, and premature aging.
Amstill Roofing has over 50 years of experience serving Texas homeowners and holds certifications from major manufacturers, including Owens Corning Platinum and GAF Master Elite status. These credentials are maintained through ongoing training and compliance with updated industry standards.
