Factors That Affect the Aging of an Asphalt Roof

Over time, your roof will definitely suffer from age-related issues. It is a natural process that causes shingles to deteriorate. Several factors determine how well an asphalt roof ages. Among them is long-term exposure to the elements. 

Total Shingle Quality

Low-quality shingles will definitely fail much sooner than high-quality shingles. Quality differs among manufacturers and even among a manufacturer’s product line. TAMKO®, CertainTeed® and Owens Corning® offer the best quality products, styles and colors.

Roof Orientation and Slope

South-facing roof slopes must contend with increased thermal cycling and ultraviolet (UV) exposure. Prevailing winds will also affect some portions of the roof. Flat roofs won’t last as long as roofs with steeper pitches. It’s because they shed moisture slower and get more direct exposure to UV radiation. These factors cause roofing issues and shorten the roof’s lifespan.

Climate and Thermal Cycling

Wind, moisture and thermal cycling all cause deterioration of asphalt roofing materials. Daily significant temperature swings cause more expansion and contraction. They increase the rate of deterioration.

Elevation and Ventilation

Homes built at higher elevations are exposed to more UV radiation. This deteriorates most roof coverings faster, including asphalt shingles. Inadequate roof ventilation can’t keep asphalt shingles cool, causing loss of volatiles. This results in thermal cycling and earlier roof replacement.
