Not all shingles are created equal.

In Michigan, your roof has to survive:

  • Freeze–thaw cycles
  • Ice dams
  • Heavy snow loads
  • Wind-driven rain
  • Summer heat swings
  • Spring storms

When homeowners choose a roofing system, they’re not just choosing color — they’re choosing durability, warranty protection, and long-term ROI.

That’s why many Michigan homeowners choose a GAF roofing system.

This guide explains:

  • What makes GAF different
  • Why system-based roofing matters
  • How warranties actually work
  • When upgrading makes financial sense
  • Whether it’s worth the investment

What Is GAF Roofing?

GAF is North America’s largest roofing manufacturer and produces:

  • Architectural asphalt shingles
  • Underlayments
  • Starter strips
  • Ridge caps
  • Ventilation systems
  • Ice & water barriers

Unlike generic shingle installs, a GAF system is designed to work as a complete roof system — not just individual components.

Why a Roofing “System” Matters in Michigan

Michigan weather stresses every layer of your roof.

A system-based approach protects against:

  • Wind uplift
  • Ice dam backup
  • Water infiltration
  • Premature shingle aging
  • Ventilation imbalance

When all components are designed to work together, performance improves — especially during severe weather.

Stronger Wind Resistance

Many GAF architectural shingles carry wind ratings of:

  • 110 mph standard
  • 130 mph enhanced with proper installation

Proper installation is critical. Nail placement and starter strip sealing determine whether those wind ratings hold.

Superior Ice & Water Protection

Michigan homes are especially vulnerable to ice dams.

GAF systems often include:

  • Ice & water shield at eaves
  • Synthetic underlayment
  • Proper ventilation balancing

Industry-Leading Warranties

One major reason homeowners choose GAF is warranty protection.

Standard coverage often includes:

  • Lifetime limited shingle warranty
  • Wind coverage (with enhanced options)
  • Algae resistance coverage

Certified contractors can offer enhanced warranties not available through non-certified installers.

Why Contractor Certification Matters

A premium shingle installed poorly performs like a basic shingle.

Choosing a GAF-certified contractor means:

  • Installation meets manufacturer standards
  • Nail placement is correct
  • System components are used properly
  • Warranty protection remains valid

Is a GAF Roof More Expensive?

Typically, yes — slightly.

But the difference often pays for itself through:

  • Longer lifespan
  • Fewer repairs
  • Stronger wind resistance
  • Better warranty protection
  • Higher resale appeal

The real comparison isn’t “cheap vs premium.”

It’s:

“Replace once properly” vs “repair repeatedly.”

  • Improve curb appeal
  • Increase buyer confidence

  • Your roof is 15–20+ years old
  • You’ve experienced repeated wind damage
  • You’re already replacing
  • You want enhanced warranty protection
  • You plan to stay in your home long-term
