6 Factors That Can Influence an Asphalt Roof’s Lifespan

Asphalt shingles are suitable for various roof types and sizes. You can get them in a wide range of designs and colors, with some even resembling other materials like wood and slate. This popular roofing option is also known for its durability and cost-effectiveness. 

Different factors can affect the lifespan of an asphalt shingle roof. Here are six of them.

1. Installation

Quality installation is the foundation of a sturdy and long-lasting asphalt shingle roof. Properly secured shingles are more likely to stand the test of time. On the other hand, poor craftsmanship can increase the likelihood of damage and early deterioration. 

2. Material Quality

Not all asphalt shingles are created equal. Homeowners have various options, from standard three-tab shingles to premium, architectural ones. While high-quality materials come with a higher price tag, they typically have a longer lifespan. You can also expect them to offer excellent weather protection. 

3. Ventilation and Insulation

Attic ventilation and insulation can impact an asphalt roof’s longevity. Lack of airflow in your attic can result in heat and moisture build-up, accelerating the deterioration of different roofing components, including shingles. It can also heighten the risk of rot, mold growth and other moisture-related problems. A well-ventilated and insulated attic and roof will maintain a more consistent temperature, helping prevent these issues. 

4. Environmental Conditions

Where you live can influence how long your roof lasts. Harsh UV rays, salt air, high winds and temperature extremes can speed up wear and tear. Choosing materials suitable for your location can help maximize your roof’s longevity. 

5. Maintenance

Regular maintenance and inspections can prolong an asphalt shingle roof’s lifespan. They allow professionals to identify and address minor issues before they escalate into significant problems. Schedule an inspection at least once a year and after severe storms. If your roofer discovers problems, get repairs immediately to prevent further damage. 

6. Slope and Design

Your roof’s slope and design affect its visual appeal and service life. Steeper roofs usually shed water and debris more efficiently, reducing the risk of water damage. On the other hand, flat or low-slope systems may require more upkeep to remain in good condition.
