If you're thinking about replacing your roof, you’ve probably wondered: “Can I install a new roof over an old one in Bismarck, ND?” The answer is yes—if it's done by qualified professionals. This method is called overlay roofing, and it can save you money while keeping your home protected. At Teamwork Exteriors—Experts in overlay roofing in Bismarck, we’ve helped hundreds of homeowners cut costs and improve roof performance using the right materials, certifications, and installation practices.

But there’s another benefit: installing a new roof over old one with GAF roofing systems may help reduce your home insurance premiums.

Why Roofing Systems Affect Your Insurance Rates

Insurance companies care about roofing systems because your roof plays a major role in protecting your home from the weather. GAF roofing products, especially when installed by a GAF Master Elite® Contractor, are trusted because of their proven performance, including:

• UL 2218 Class 4 impact-resistant shingles

• Fire resistance and leak barriers

• Roof deck protection and System Plus Limited Warranty

A better roof means fewer claims, and that means insurance companies may offer insurance premium discounts for homes with strong, impact-resistant roofing materials like GAF.

What Makes GAF Roofing a Smart Choice?

When you're exploring roofing options, GAF stands out. These roofing shingles are not just tough—they’re designed with energy efficiency, durability, and customer satisfaction in mind. Whether you choose asphalt shingles, metal roofing, or even eco-friendly roofing materials, GAF has a system built for long-term savings.

Here’s what makes a GAF roof appealing to both homeowners and insurers:

• Certified through a GAF certification program

• Available with Roofing System Limited Warranty

• Installed only by top-level GAF certified contractors

• Helps meet the insurance industry's standard for roof rating system

And the best part? GAF roofing works hand-in-hand with insurance scopes of work and insurance restoration work, making the claim process smoother when you need it.

Is Overlay Roofing a Good Idea?

Let’s answer a common question: “Is overlay roofing a good idea?” It depends on your roof’s condition, roof type, and roof shape—but in many cases, yes.
