How long does a roof last in Missouri?
In Mid-Missouri, a standard asphalt shingle roof typically lasts 20 to 25 years depending on installation quality, ventilation, and exposure to severe weather. Architectural shingles can last 25 to 30 years. Missouri's frequent hailstorms, high winds, and temperature swings can shorten roof lifespan. Adding GONANO nano-coating can extend your roof's life by an additional 10 to 15 years.
