What Are SBS-Modified Asphalt Shingles—and Are They Worth It?

When it’s time to replace your roof, not all asphalt shingles are created equal. If you’re a homeowner in Oshkosh or anywhere in Wisconsin, you know your roof needs to do more than just look good—it needs to hold up against snow, ice, wind, and even the occasional hailstorm.

That’s where SBS-modified asphalt shingles come in. At Rutter’s Roofing, we proudly install these premium shingles because they offer real advantages in durability, flexibility, and long-term value. Here’s what makes them different—and why more Wisconsin homeowners are making the switch.

What Does “SBS-Modified” Mean?

SBS stands for Styrene-Butadiene-Styrene, a type of synthetic rubber that’s blended into traditional asphalt during the manufacturing process. The result is a rubberized roofing shingle that’s tougher, more flexible, and more resilient than standard options.

Think of it like the difference between regular asphalt and a flexible, high-performance polymer—it bends instead of breaking.

Key Benefits of SBS-Modified Shingles

Superior Impact Resistance

Wisconsin sees its fair share of hail and flying debris in high winds. SBS-modified shingles are engineered to absorb impact without cracking. Many carry Class 4 impact ratings, which may even qualify you for insurance discounts.

Cold-Weather Flexibility

Ordinary shingles can become brittle and prone to cracking in subzero temperatures. SBS-modified shingles remain pliable in the cold, making them ideal for winter installations and long-term durability in northern climates.

Enhanced Longevity

Thanks to their improved elasticity and resistance to granule loss, these shingles typically last longer than standard architectural shingles. Some SBS-modified products offer 40- to 50-year warranties when installed as part of a complete system.

Stronger Seal and Wind Uplift Resistance

The rubberized asphalt adheres more effectively, forming a tighter seal that resists wind uplift during storms. This means fewer blow-offs and less maintenance over the life of your roof.

Are They Worth the Investment?

If you’re comparing prices, SBS-modified shingles may cost slightly more than traditional options—but the return is clear:

• Fewer repairs after storms
• Longer roof life under Wisconsin weather conditions
• Better protection for your home and family
• Potential insurance savings

In short, you’re investing in a roof that’s built to last—and one that’s less likely to let you down when the weather gets rough.
