What Record Vancouver Rainfall Can Mean for an Unmaintained Commercial Roof

How Record Rainfall in Vancouver Can Damage Commercial Roofs

January was a record month for rain in Vancouver. While rain can be inconvenient, it can also be extremely damaging when it comes down in large quantities. Commercial roofs that have not been properly maintained are especially prone to suffering severe, and costly, damage.

Why Regular Commercial Roof Maintenance Matters in Wet Weather

Commercial roof maintenance should be part of every building owner's regular schedule. Unfortunately, it is far too often neglected, and combined with record rainfall, this can lead to serious problems.

Freeze-Thaw Cycles, Cracks, and Water Ingress Risks

When temperatures however above and below the freezing mark, this creates a freeze-thaw cycle that can damage roofing tiles. This damage is most often in the form of small cracks. Heavy rainfall and pooling water can then be absorbed through these cracks, and cause serious damage to the interior of the building.

How Heavy Rain Can Lead to Curling or Buckling Shingles

Heavy rainfall can also cause what is known as curling or buckling shingles. These damaged shingles also no longer protect the roof, and water is allowed to leak on.

How Commercial Roof Inspections Help Prevent Leaks and Pooling Water

Regular maintenance allows roofing experts to ensure that everything is watertight, and no cracks or curling signs are present. Your Vancouver commercial roofing company will also ensure that drains and water runoffs are free debris and working properly. This helps to prevent water from pooling on the roof, further reducing the risk of a catastrophic leak.

Schedule Preventive Roof Maintenance Before the Next Major Rain Event

When the weather is dry and calm it can quickly too easy to ignore regular maintenance. However, heavy rain and devastating weather can quickly happen, and not being prepared can lead to much larger losses. Have Laurentian Roofing inspect and maintain your commercial roof so you will be prepared should the record rainfall return again.
