Commercial roofing leaks can damage inventory and result in downtime. Fortunately, securing professional repairs at the first sign of moisture infiltration can help minimize the issue. Protect your building by staying alert for these common indicators of water damage.

How Can I Tell if My Commercial Roofing Is Leaking?

1. Dirt Rings

Roofs, including flat ones, should not develop pooling. Puddles are usually caused by low spots on the outer membranes, which could've sagged due to damage.

Standing water leaves behind circles of sediment on the roof. The water may have simply evaporated, or it could've drained into the ceiling. Either way, a contractor must restore proper drainage by repairing the affected membrane to prevent water infiltration.

2. Surface Damage

Open seams and misshapen flashing allow water to enter the building. Moisture can eventually saturate the weatherproofing layer below the surface, which warrants full roof replacement. 

Scheduling prompt repairs whenever you notice gaps on the surface can stop leaks before they affect the rest of the structure.

3. Increased Energy Bills

In the winter, the insulation directly beneath the roof helps trap warm air inside the building and keep cold air out. If insulating materials get wet and compressed because of a leak, they won’t work anymore.

This results in spiking energy costs as the HVAC system runs for longer or more frequently to maintain a comfortable temperature. Schedule roof inspections whenever you notice unusually high utility bills.

4. Mold Growth

When trapped moisture raises the humidity levels, it creates an environment where mold and mildew thrive. These growths are unhealthy to breathe and spread to surrounding building materials. Mold and mildew produce stains on walls and ceilings. They also emit pungent, musty, or rotten odors.

5. Bubbling Walls

As water runs down walls, it can affect paint and drywall. Paint may discolor or peel, while plaster may absorb the moisture and swell. Metal walls can corrode with continual exposure to moisture, creating streaks and flaking. 

Wall damage is a surface sign of hidden issues caused by a longstanding leak, so call a contractor immediately upon noticing these problems.
