What is a common consequence of improperly installed or damaged ridge caps on a roof?

Improperly installed or damaged ridge caps can lead to significant issues, with water infiltration being one of the most common consequences. Ridge caps are essential for sealing the joints at the peak of a roof, where two sloping sections meet. When these caps are not correctly positioned or have been compromised by damage, they no longer effectively prevent moisture from entering the roof assembly.

Water infiltration can result in numerous problems, including the development of mold and mildew, damage to the roof structure, and deterioration of insulation and interior materials. Moreover, persistent leaks can lead to costly repairs over time, making the integrity of ridge caps crucial in maintaining the overall health of a roofing system.

The other options, such as increased insulation, enhanced roof durability, and improved ventilation, are not associated with the repercussions of improper ridge cap installation. In fact, these elements are typically compromised rather than improved when ridge caps fail to perform their intended function.
