Can flashing damage cause bricks to crack?

The Intricate Relationship Between Flashing Damage and Brick Cracking

In the bustling heart of Montreal, where the allure of ancient architecture meets modern design, the structural integrity of a building remains paramount. At Maçonnerie Montréal, we pride ourselves on delivering top-tier masonry services. One pressing concern we often encounter is the potential for damaged flashing to cause bricks to crack. Let's delve deep into this topic, shedding light on this intricate relationship.

Understanding the Role of Flashing in Masonry

Flashing, an essential component in masonry, acts as a barrier, preventing water from infiltrating the building. Typically installed at intersections and joints, it ensures water is directed away from these vulnerable points. When flashing is compromised, it can lead to water infiltration, which in turn can cause a myriad of structural issues, including brick cracking.

How Damaged Flashing Can Lead to Brick Cracking

1. Water Accumulation and Freeze-Thaw Cycles

In Montreal's unpredictable weather, water that seeps into small crevices due to compromised flashing can freeze during cold temperatures. As water freezes, it expands, exerting pressure on the surrounding bricks. Over time, repeated freeze-thaw cycles can cause bricks to crack or even dislodge.

2. Salt Crystallization

Water infiltration due to damaged flashing can carry soluble salts. As the water evaporates, these salts crystallize, leading to what's known as salt efflorescence. This crystallization can exert pressure on the bricks, leading to potential cracking.

3. Moisture Expansion

Bricks are naturally porous. When they absorb excess moisture due to compromised flashing, they can expand. Continuous moisture expansion can lead to bricks pushing against each other, resulting in cracks.

Preventive Measures to Protect Your Masonry

1. Regular Flashing Inspections

Conducting regular inspections, especially after extreme weather conditions, can help in early detection of any damage to the flashing, ensuring timely repairs.

2. Proper Installation

Ensuring that flashing is installed correctly during the initial construction phase can significantly reduce the risk of future damage. Employing experienced masonry professionals for installation is crucial.

3. Use of Quality Materials

Opting for high-quality, durable flashing materials can enhance the longevity of the flashing, reducing the chances of damage and subsequent brick cracking.
