Asphalt shingles are the most widely used roofing material in the United States. Known for their affordability and ease of installation, they are a practical choice for many homeowners. However, they are not without issues that can affect their durability and functionality. Asphalt roofing offers an economical solution, but addressing its limitations is essential for maximizing its lifespan and performance.
Common Problems:
Short Lifespan
Asphalt shingles generally last 20–30 years, which is significantly less than other roofing materials like slate or metal. This shorter lifespan can make them less cost-effective in the long run. Factors like extreme weather, improper installation, and poor ventilation can further shorten their life expectancy. Over time, the shingles deteriorate, losing their protective granules and exposing the roof to potential leaks. Homeowners in areas with severe weather conditions may notice even faster degradation. This limited durability often necessitates frequent replacements, increasing overall costs.
Granule Loss
The granules on asphalt shingles provide protection against UV rays and weathering. Over time, these granules can wash away due to rain, wind, or foot traffic during maintenance. Granule loss leaves the shingles exposed to sunlight, accelerating their aging process. It can also lead to inconsistent roof appearance, with bald spots creating visual and functional concerns. If granule loss is severe, the shingles may become prone to cracking, further compromising their waterproofing ability. This issue is especially noticeable after storms or heavy rains.
Weather Damage
Asphalt shingles are susceptible to damage from strong winds, hail, and extreme heat. High winds can lift shingles, leaving the roof exposed to water infiltration. Hail can cause dents or punctures, reducing the roof’s effectiveness. Extreme heat can cause shingles to warp, curl, or crack over time, particularly in regions with prolonged sun exposure. These issues not only affect the roof’s functionality but can also result in significant repair costs. Regular exposure to harsh weather increases the likelihood of premature failure.
Algae and Moss Growth
In humid or shaded areas, algae and moss can grow on asphalt shingles, causing discoloration and potential damage. Algae create dark streaks that detract from the roof’s appearance, while moss traps moisture against the shingles. Over time, this moisture can weaken the shingles and promote decay. If left untreated, moss can lift shingles, creating entry points for water. The presence of algae and moss also adds maintenance tasks for homeowners, especially in climates conducive to their growth.
Solutions:
Schedule Regular Inspections
Annual roof inspections are essential for identifying early signs of wear and tear. During inspections, a professional can check for loose or damaged shingles, granule loss, and weather-related damage. Early detection allows for timely repairs, preventing small problems from escalating into costly issues. Inspections are particularly crucial after severe weather events, which can cause hidden damage. Routine check-ups ensure the roof remains in optimal condition and prolong its lifespan.
