How are tears in water resistive barriers generally addressed?

Tears in water resistive barriers (WRBs) are critical issues that can compromise the effectiveness of the barrier in preventing moisture intrusion. Properly repairing these tears is essential to ensure the barrier functions as intended. Neglecting the tears or inadequate measures could lead to moisture problems within the building envelope, potentially resulting in mold growth, structural damage, or reduced energy efficiency.

Addressing tears with correct repairs involves using compatible materials and techniques to restore the integrity of the WRB. This might include applying patches or sealants designed for the specific type of WRB material. Proper repairs help maintain the continuity of the barrier, ensuring that water does not penetrate through the damaged area.

While covering tears with additional layers of WRB might seem like a viable option, it does not provide a direct fix to the issue and could lead to future complications. Similarly, simply painting over the tears does not effectively seal or repair the physical damage, leaving potential points of water entry. Ignoring the issue altogether could lead to severe long-term problems. Hence, the best practice is to ensure that any tears are repaired properly to maintain the overall integrity and functionality of the water resistive barrier.
