When it’s time to replace your roof, it’s tempting to think all contractors are the same. But there’s a big difference between a crew that can put shingles on your house and a company that’s backed by the largest roofing manufacturer in North America.
At Michaelson Roofing Improvements (MRI), we’re proud to be a GAF-Certified Contractor—and that’s not just a title. It’s a seal of approval that ensures your roof is installed by professionals who follow strict industry standards and deliver lasting results.
Let’s break down what it means to be GAF-certified and why that certification is your best protection when making a major investment in your home.
What Is GAF Certification?
GAF is the leading roofing manufacturer in the country, and they don’t hand out certifications lightly. To become certified, a contractor must:
- Be properly licensed and insured
- Demonstrate a proven history of quality installations
- Participate in ongoing training and education
- Maintain a strong reputation with homeowners
Only a small percentage of roofers earn this title. When you hire MRI, you’re hiring a team that’s been vetted by the people who make the product—not just by an online review or a flyer on your door.
The Big Advantage: Better Warranties
Here’s the truth: warranties are only valid if the installation meets manufacturer specs. That means if a non-certified roofer skips steps or mixes incompatible materials, you could lose the protection that comes with your new roof.
As a GAF-Certified Contractor, MRI can offer:
- Lifetime limited warranties on shingles
- 50-year coverage on entire roofing systems (with proper components)
- Labor, tear-off, and disposal coverage—not just materials
- Transferable warranties that add resale value to your home
Why Homeowners Trust GAF-Certified Installers
When you work with a certified contractor, you get:
- Verified use of GAF components (no shortcuts)
- Installation that follows GAF’s exact instructions
- A team that’s trained on the latest products and techniques
- Peace of mind that your roof was built the right way, from the decking up
The MRI Process: Professional, Documented, Complete
At MRI, we install the full GAF roofing system – not just shingles. That includes:
- Synthetic underlayment
- Starter strips
- Ice and water shields
- Ridge caps and proper ventilation
And we don’t leave it up to chance. Every job comes with photo documentation and a detailed Stages Report so you can see exactly what was installed.
Our Promise: We’re Here Long After the Roof Is Done
Every full replacement includes 6 and 12-month inspections – completely free. We come back to verify that everything sealed and cured correctly, and that the system is still performing exactly as intended.
You’ll never wonder what was done, who did it, or if it’s covered.
So—Does Certification Matter?
Ask yourself:
- Will the person installing my roof still be around in 10 years?
- Can I trust the warranty I was promised?
- Is the contractor providing photos and documentation of the install?
- Do I know exactly what products are being used?
If any of those answers make you pause, it’s time to get a second opinion.
MRI offers free roofing inspections, honest guidance, and installation you can trust—for the long haul.
