When Iowa homeowners start thinking about a roof replacement, one of the first questions that comes up is “How long will my new roof last?” The answer depends on the materials you choose, the weather conditions in Iowa, and the skill of your installer. At J. Bos Inc. Roofing Services, we’re a CertainTeed Certified Master Shingle Applicator, so our installations are backed by strong manufacturer warranties and built to withstand Midwest weather.
Below, we’ve answered the most common questions Iowa homeowners ask about roofing lifespans and why CertainTeed is one of the best choices for long-term value.
Most roofs in Iowa last 15–25 years depending on materials, ventilation, and installation quality. Asphalt shingles make up the majority of roofs in Central Iowa, but hail, wind, and ice can shorten their lifespan if they weren’t installed with today’s standards for underlayment and flashing.
A CertainTeed roof is designed to last 30 years or more, with many products carrying a lifetime limited warranty. Premium options like the Presidential Line, offer enhanced durability and curb appeal, often outlasting standard shingles by a decade or more. When installed by a certified contractor like J. Bos Roofing, your warranty stays intact, protecting your investment long term.
Iowa’s weather is tough on roofing systems. CertainTeed shingles are engineered for performance with features that make them a stronger choice:
Impact resistance: Many CertainTeed shingles meet UL 2218 Class 4 hail ratings.
Wind resistance: Rated up to 130 mph, they’re built to stand against Iowa’s windstorms.
Integrated system: The Integrity Roof System® includes underlayment, starter shingles, ventilation, and ridge caps for full-home protection.
Warranty strength: Backed by CertainTeed’s warranty when installed by certified professionals.
