How to Repair a Commercial Flat Roof

If your commercial property has a flat roof, it is essential to repair it promptly in order to keep it functioning optimally and save you money in the long run.

When fixing a flat roof, there are numerous factors to take into account. These include the material it is made from, its age, and how much maintenance has been provided.

Roof Leaks

If your flat roof leaks water into your building, there are a few solutions to fix the problem. Applying bitumen primer, bitumen-based paint, or torching roof felt onto any cracks will all work to stop water infiltration.

First, attempt to identify where the leak is coming from. This is usually easier on flat roofs than sloped or shingled ones.

Once you’ve identified where the water is dripping, climb a ladder and measure from the ceiling to the dripping area.

Next, inspect for damage or pooling water above where you measured. If so, this suggests a leak comes from an exposed low spot in the roof.

On a concrete roof, look for cracks or holes that have formed over time. These are often the source of roof leaks on buildings made of this material. Repairing these small areas can help avoid further water damage and secure your property.

Damaged Membrane

Damaged membranes can lead to leaks and other problems. Whether due to physical deterioration or weathering, it must be repaired promptly.

The roof membrane is one of the most essential elements of a commercial flat roof system. Its primary role is to prevent water infiltration under insulation, into the structure below, leading to costly repairs.

Furthermore, roof membranes protect the interior of buildings by offering protection from weather elements. Roof membranes come in various materials like synthetic rubber, thermoplastic polyolefin (TPO), liquid polyurethane, or modified bitumen.

No matter the material, having a commercial membrane roof inspection at least once annually is necessary. This will enable your contractor to detect any issues with the roof and advise you whether repairs or full membrane replacement is needed.

Besides the obvious signs of damage, flat roofs can also be punctured by wind-carried debris and branches falling from overhanging trees. These punctures damage the membrane, which in turn leads to water leaks and other issues.

Debris on the Roof

Debris on roofs can lead to numerous issues, such as leaks, water dams and damaged materials. It also clogs drains and vents, creating barriers which pond water and cause moisture damage.

Regularly clearing debris off of your flat roof is essential. A broom is an ideal tool for this task.

Ideally, you should clear away all debris that has built up on your roof. However, if you cannot do it yourself, you can hire a professional company that will do it for you.

The initial step in fixing a commercial flat roof is to check for cracks or holes in its membrane. This will give an indication of where the leak originates from.

Moisture Accumulation

If you own a commercial flat roof, it is essential to check for moisture accumulation on it regularly. Over time, water can build up and cause structural damage and expensive repairs.

Commercial flat roofs often retain rainwater, which then pools on top for days or weeks at a time – this is known as ponding and can be especially detrimental to the membrane of your roof if left unchecked.

Ponding may be caused by debris accumulation on your roof. This could include sticks, branches, leaves, and other organic materials.

Another common issue with flat roofs is blistering. This occurs when small pockets of air or moisture become trapped beneath the membrane or between layers.

Blistering can be difficult to repair, so it’s essential that you address them as soon as you notice them. If there are blisters present, they should either be filled with new roofing material or repaired by an experienced roofer.
