When you invest in a new roof, one of the biggest questions is:
How long will it last?
Most asphalt shingle roofs last around 20 years, but that number can vary depending on the materials used, the installer’s expertise, and the level of warranty protection.
At J. Bos Inc. Roofing Services, we use CertainTeed roofing systems—a trusted brand with some of the most advanced warranties in the industry. While CertainTeed doesn’t list a guaranteed lifespan, their product tiers and protections offer a helpful way to compare performance and value over time.

Landmark® PRO or ClimateFlex®
This category offers enhanced durability and greater protection against storm damage.

Choosing a mid-tier product can help your roof stand up better to Iowa’s hail and seasonal weather extremes.

Presidential Shake® TL or Grand Manor®
These premium designer shingles are made for long-term performance and visual impact.
- Heavier, multi-layer construction mimics wood shake or slate

- Class 4 impact resistance
- Greater curb appeal and long-term consistency
These products are often selected for high-end homes where durability and appearance matter most.
Why Shingle Quality Matters
Higher-quality shingles resist wear, fading, and impact damage better over time. They also reduce the risk of early failure from Iowa’s high winds, hail, and seasonal shifts. When paired with expert installation and proper attic ventilation, these shingles can easily meet or exceed their lifespan expectations.
So, How Long Does a Roof Last?
While 20 years is a common benchmark, the actual lifespan of your roof depends on:
- The product you choose
- Whether your roofer is certified by the manufacturer
- Proper attic ventilation and roof design
- The strength of the warranty you receive
Upgrading to higher-tier shingles with impact resistance, algae protection, and extended warranties can improve long-term performance, especially when installed by a certified contractor like J. Bos Inc. Roofing Services.
