What is typically the primary concern with a fiberglass shingle roof installation?

Leak prevention is typically the primary concern with a fiberglass shingle roof installation because the primary purpose of roofing materials is to protect the structure from water intrusion and damage. Properly installed fiberglass shingles must effectively shed water to prevent leaks, which can lead to significant issues inside the home, including mold growth, structural damage, and deterioration of building materials.

During installation, factors such as underlayment, flashing, and the alignment of the shingles themselves play crucial roles in ensuring a watertight seal. If any part of the installation is not executed correctly, it can create vulnerabilities that allow water to penetrate, making leak prevention the most critical focus for homeowners and inspectors alike.

While cost efficiency, color matching, and durability are important considerations, they do not directly address the immediate need to prevent water from entering the home, which can have more severe and costly consequences.
