When it comes to your roof, most homeowners focus on the shingles—but the truth is, installation matters just as much as the materials.
At GPI Inc., we believe that the difference between a roof that lasts 30 years and one that fails early often comes down to who installs it. That’s why working with a CertainTeed Master Craftsman™ Roofing Contractor is such a big deal.
What Is a CertainTeed Master Craftsman™ Roofing Contractor?
The Master Craftsman™ program from CertainTeed is an advanced training and certification program designed to ensure a roofing contractor meets the highest standards in the industry.
This isn’t just a title—it’s earned through:
- In-depth training
- Proven installation knowledge
- Passing a rigorous certification exam
It’s also the first step toward even higher certifications like ShingleMaster™ and SELECT ShingleMaster™.
What A Roofing Contractor Learns in the Master Craftsman Program
To become certified, contractors must master every critical part of roofing—not just the basics.
Proper Workmanship Practices
Precision installation is everything. Even the best shingles can fail if they’re not installed correctly.
Complete Roofing Systems
A roof isn’t just shingles—it’s an entire system. Certified contractors understand how all components work together for maximum performance.
Accurate Estimating
No guesswork. Proper training ensures homeowners get fair, transparent, and accurate project pricing.
Flashing & Ventilation
These are two of the most common failure points on a roof. Master Craftsman contractors are trained to install them correctly to prevent leaks and extend roof life.
Manufacturer-Approved Installation
Following CertainTeed’s exact installation guidelines helps ensure your roof performs as designed—and stays protected under warranty.
Why This Certification Matters for Homeowners
Hiring a certified contractor like GPI Inc. gives you a major advantage.
Higher Quality Installation
You’re getting a contractor who has been trained and tested—not just someone learning on the job.
Stronger Warranty Protection
Improper installation can void manufacturer warranties. Certified contractors follow the correct process to keep your coverage intact.
Longer Roof Lifespan
When every detail is done right—from ventilation to flashing—your roof simply lasts longer.
Peace of Mind
You know your home is protected by a contractor committed to ongoing education and industry best practices.
