Your building’s roof might start out keeping you and your workers safe and dry, but it will begin to deteriorate over time. Because so many commercial buildings have flat roofs, there are some special issues to consider, such as damaged roof membranes and low spots where water can settle. Here are 5 of the most common causes of commercial roof leaks.

Cause 1: Pooling Water

If your commercial building has a flat roof that isn’t level, water can pool in different areas and cause the roof to sag or leak. Buildings typically have large roofs, and water weighs about five pounds per square inch. This is a lot of extra weight that can eventually bog down your roof and cause cracks that allow water to seep through. Pooling water can usually be fixed by leveling the roof and repairing or replacing the drainage system.

Cause 2: Damaged Roofing Membrane

Roofing membranes help seal flat roofs and make them waterproof, but these materials can get damaged by sun and weather over time. When this happens, you might see cracks, shrinkage, blistering, or holes that expose the roof’s insulation. This damage permits water to enter your roof and flow down into your building. When this happens, repair or replacement of the membrane is the only choice.

Cause 3: Damaged Flashing

Flashing protects your roof membrane’s exterior edges. It also helps seal the area around your chimney and vents. As your roof is damaged by the weather and fluctuating temperatures, the flashing can expand, contract, and become loose. This creates an entry point for water, allowing it to pour under the membrane. If your flashing breaks, it could cause the underlying roof structure and ceiling to deteriorate due to moisture damage. Get it repaired as quickly as possible.

Cause 4: Improper Sealing

The purpose of a roof membrane and flashing is to make your roof as waterproof as possible. This isn’t so effective, however, when you have other points on the roof where water can flow in unchecked. Pipes, vents, drains, HVAC units and hot stacks all need to be properly sealed to prevent leaks from occurring. Otherwise, they act as holes in the membrane. We recommend having a professional seal and inspect them. Even after they are sealed, these areas will need to be closely watched for signs of water entry.

Cause 5: An Aging Roof

No roof lasts forever. Flat roofs usually have a lifespan of 15 or 20 years before they need to be replaced. If your building’s flat roof is getting on in years, it could be time for a replacement.
