When considering roofing materials, many Missouri homeowners find themselves wondering, how long do asphalt shingles last? Given the widespread use of asphalt shingles across the U.S., understanding their longevity in Missouri’s unique climate is crucial.

From varying seasons to unexpected weather events, various factors determine the durability of these shingles. In this guide, we’ll explore the lifespan of asphalt shingles in Missouri and delve into the key influencers affecting their durability.

Climate Conditions in Missouri

Missouri’s climate varies, posing distinct challenges to roofing materials. Its central location in the U.S. makes it a meeting point for various weather patterns.

Seasonal Variations

The state experiences all four seasons, with hot summers and cold winters. During summer, temperatures can soar, while winters can bring snow and ice.

Severe Weather Incidents

Missouri is also known for its occasional severe weather, including tornadoes, hailstorms, and heavy rainfalls. These events can take a toll on roofing materials, including asphalt shingles.

Expected Lifespan of Asphalt Shingles

On average, asphalt shingles can last anywhere between 15 to 30 years. However, in regions like Missouri, where weather conditions can be harsh and unpredictable, the lifespan can be on the lower end of this spectrum.

Quality Matters

The quality of the asphalt shingles plays a significant role in their durability. High-quality shingles are more resilient to adverse weather conditions and tend to last longer.

Maintenance and Upkeep

Regular maintenance can extend the lifespan of the shingles. By addressing minor issues promptly, homeowners can prevent larger problems down the line, which might affect the roof’s integrity.

Factors Influencing the Longevity of Asphalt Shingles in Missouri

Several factors can influence how long asphalt shingles last in the state.

Installation Technique

A properly installed roof is critical. Poor installation can reduce the lifespan of the shingles, regardless of their quality. It’s essential to ensure that the roofing contractor is experienced and uses the correct techniques.


Proper attic ventilation can prevent heat and moisture buildup. Excessive heat and moisture can deteriorate the shingles prematurely, reducing their lifespan.

Sun Exposure

Roofs that are directly exposed to the sun for most of the day may see faster wear and tear. The ultraviolet (UV) rays can cause the shingles to fade and become brittle over time.

Growth of Algae and Moss

Dark streaks on roofs in Missouri are often caused by algae growth. Additionally, moss can grow on shingles, especially in shaded areas. Both can damage the roof and reduce the lifespan of the shingles.


Asphalt shingles are a durable and cost-effective choice for homeowners in Missouri. While the state’s varying climate conditions can pose challenges, with proper installation, quality materials, and regular maintenance, homeowners can expect their roofs to serve them well for many years.
