Which of the following is NOT a problem associated with asphalt shingles?

Deterioration is a well-known characteristic of asphalt shingles, primarily due to the exposure to various environmental factors such as UV rays, moisture, and temperature fluctuations. Asphalt shingles are designed to last a certain number of years, typically around 20 to 30, but they do inevitably face deterioration over time. This can manifest as curling, cracking, or the loss of granules, all of which can compromise the integrity of the roofing system.

In contrast, the other options reflect issues that can arise with asphalt shingles but are not inherent to the material itself. Weather issues refer to external factors affecting the performance and lifespan of the shingles, while debris accumulation can lead to water pooling and potential damage if not addressed. Material failures can occur due to manufacturing defects or improper installation, but these are often situational rather than a universal problem associated with asphalt shingles as a whole.
