True or False: Sealants used in place of flashing can be considered a defect.

Using sealants in place of flashing is generally considered a defect because flashing serves a critical role in directing water away from vulnerable areas of a structure, such as roof penetrations, wall intersections, and other areas prone to water infiltration. Flashing is specifically designed to withstand environmental exposure and provide durable protection over time.

Sealants, while they may provide some level of water resistance, are not a substitute for properly installed flashing. They can break down, lose adhesion, or become less effective over time due to aging, temperature fluctuations, and UV exposure. This can lead to leaks and water damage, which can compromise the integrity of the building structure.

In standard building practices, using sealant as a primary means of waterproofing in place of a physical barrier like flashing indicates a misunderstanding of proper construction methods and can lead to future issues, making it a defect in construction.
