What characteristic of organic shingles can affect installation?

Organic shingles, often made from felt paper saturated with asphalt and coated with granules, are known to exhibit certain physical characteristics that can impact their installation. One significant characteristic is distortion.

Distortion can occur when organic shingles become wet or experience temperature changes, which may lead them to curl, warp, or otherwise change shape. If the shingles are distorted before installation, they may not lay flat against the roofing surface, leading to poor adhesion and potential vulnerabilities to weather conditions, such as wind and rain. This can create gaps that compromise the roof's integrity.

It's important for installers to account for any distortion to ensure that the shingles are properly positioned to form a tight seal. Addressing distortion effectively helps avoid problems like leaks or early wear, ensuring the longevity and performance of the roofing system.

While weight, cost, and installation complexity can also play roles in the overall roofing project, they do not directly affect the immediate installation process of the shingles in the same manner that distortion does.
