Signs and Symptoms: When to Seek Commercial Flat Roof Repair

The flat roofing market is expected to reach a value of $52.3 billion by 2031. Flat roofs are a popular choice for commercial buildings throughout the Mid-Atlantic. Most commercial property owners often prefer flat roofing of 60 mils thickness, offering a lifespan of 20-30 years.

While a flat roof provides your building with a durable and modern look, these types of roofs also come with unique issues. If you have concerns about the condition of your roof, below are signs you need a commercial flat roof repair.

Standing Water on a Flat Roof

Perhaps the most common problem with flat roofs is pooling water. Since flat roofs have little or almost no slope, water can’t properly run off the surface.

When water settles on a flat roof, it can affect its integrity. Prolonged standing water accelerates roof deterioration. It also promotes mold and mildew growth.

What’s more, your roofs run the risk of buckling or collapsing. If you see regular standing water after it rains, it may be time to contact a commercial roofing company. An expert will assess your roof for damage to determine whether you need repairs or a replacement.

Visible Rips and Tears

Flat roofs often lack shingles. This can make it hard to detect damage like tears or holes in the roofing material. Ignoring such damage can worsen the roofing problems.

Your roof may start tearing at the seams, resulting in constant roof leaks. This can compromise your commercial building’s structure. To identify visible rips and tears, you may need commercial roofing services.

For minor rips and tears, they can patch the issue. However, you may need to replace the entire roof if the damage is extensive.

Damaged Flashing

Flashing is an essential component on flat roofs that directs water away from critical areas wherever the roof meets a vertical surface like a wall or a dormer. It helps prevent water seepage into your commercial building. With flashing, you can cover vulnerable areas where water intrusion can occur, such as at vents, chimneys, and skylights

This can help protect the integrity of your building. However, vulnerable seams can start to separate over time. As a result, you may face water damage and structural issues.

To avoid this, ensure you inspect the flashing regularly. Check for signs of loosening or flapping, especially during windy conditions. This can be a sign of flashing separating.

Early detection of flashing problems allows for less costly commercial roof repairs. Timely intervention also prevents further damage. This can help you extend your roof’s lifespan.

Blistering of the Flat Roof

Blisters on your commercial roof can occur when air becomes trapped between the roof membrane and underlayment. Although benign, they can escalate into serious issues if left unattended. Small blisters have the potential to rupture, leading to dangerous roof leaks.

Once blisters progress, you may need to replace the entire roof. To mitigate the risk of damage and costly repairs, stay on top of roofing inspections. If you notice blistering, ensure you repair the affected area as soon as possible.

Sagging Roof

A flat roof should maintain a level surface. If you notice any areas where the roof appears to sag, you may have an issue with its underlying structure. This may be due to water damage, deterioration of roofing materials, or inadequate support.

Sagging roofs pose a serious safety hazard. If left unaddressed, a sagging roof can collapse. This can cause extensive damage and harm your building’s occupants, expensive equipment, or other parts of your commercial facility

With sagging areas on this low-slope roof, you may also experience water pooling. When water accumulates in these low spots, it increases the risk of leaks and water damage. Pooled water can also accelerate the deterioration of your roofing materials.

When you notice sagging, ensure you contact expert commercial roofers as soon as possible. This way you can identify and remedy any underlying problems.

Water Spots

Water spots on a commercial flat roof often result from leaks in the roofing system. These leaks can occur due to various issues such as:

  • Damaged roofing materials
  • Deteriorated flashing
  • Improperly sealed penetrations

Ignoring water spots can lead to bigger problems over time. Water intrusion can compromise the structural integrity of your roof and commercial building. It can also damage interior finishes, insulation, and electrical systems.

As a result, it leads to costly repairs and business interruptions. To get rid of water spots, ensure you identify and repair any sources of leaks on your roof.

Membrane Problems

The protective membrane on flat roofs serves as a barrier against water damage. When this membrane deteriorates over time, it may no longer provide adequate protection against water infiltration.

If you live in an area prone to high winds, the membrane on flat roofs may become loose or detached. Carelessly flapping membranes in the wind is a visible sign of membrane problems.

A dislodged membrane can compromise the integrity of the roof system. It also increases the risk of water intrusion and structural damage. Fortunately, you can resolve some membrane problems with simple commercial repairs.

However, you may need roof replacements for extensive membrane damage. Consult with a professional roofing company to assess the extent of the damage. This will help you determine the most appropriate course of action.

Cracks in the Coating Means You Should Seek Commercial Flat Roof Repair

Some flat roofs feature a white coating system, typically made of silicone or acrylic. This offers energy efficiency and a lightweight option. Over time, this coating can develop cracks, compromising its effectiveness.

Visible cracks are a sign you need to take immediate action. Roof coatings usually have a lifespan of around 15 years. If your roof is older, keep a keen eye on any signs of cracking to ensure timely repairs.

Fasteners are Loose

Fasteners are essential in securing the membrane and other roofing materials in single-ply flat roofs. These fasteners can loosen due to weather, temperature changes, and aging.

If your flat roof appears bumpy, it may be a result of loose fasteners. Prompt attention from a professional roofer can easily remedy this issue. They can reattach or re-secure the fasteners, preventing water penetration.
