Do you have a

leaky roof?

One of the primary reasons people look into roof waterproofing services is because they have a leaky roof. When a roof is leaking, it can cause water damage and pose a risk to the structural integrity of a commercial building. 

Roof waterproofing creates a protective layer on the roof’s surface that prevents water from penetrating and causing damage. 

The process involves applying a specialized coating or membrane to the roof’s surface that acts as a barrier against water. This not only helps to repair existing leaks but also prevents future leaks from occurring, which can lead to costly repairs and damage to the property. 

By investing in professional-grade roof waterproofing, you can protect your roof from water damage and prolong its lifespan, while avoiding costly repairs associated with devastating leaks and water damage.

key advantages of
Roof Waterproofing

Commercial buildings are often larger and more complex than residences, and the roofs are subject to greater wear and tear from weather conditions, foot traffic, and equipment installations. Proper roof waterproofing can help extend the roof’s life and reduce maintenance costs over time.

Additionally, roof waterproofing provides these important benefits.

​​Protection of assets

Commercial buildings often contain valuable assets, including equipment, inventory, and electronics. Waterproofing the roof can prevent water damage to these assets, ensuring their longevity and reducing the risk of costly repairs.

Compliance with regulations

Commercial buildings are often subject to strict building codes and regulations that require proper waterproofing measures to be in place to ensure the safety of occupants.

Prevention of business disruption

Water leaks can cause significant disruption to business operations, leading to lost productivity, revenue, and even potential legal issues if customers or employees are injured.

Preservation of the building's structure

Waterproofing the roof can prevent water damage to the building’s structural components, including beams, walls, and ceilings, which can lead to expensive repairs and even compromise the building’s integrity over time.

Energy efficiency

A waterproofed roof can help regulate the temperature inside the building, reducing the need for heating and air conditioning, resulting in lower energy bills and promoting sustainability.

Moreover, a waterproofed roof prevents moisture buildup, which can lead to the growth of mold and mildew that can negatively impact indoor air quality.

Increased property value

A well-maintained and waterproofed roof can increase the value of the property and make it more attractive to potential buyers or tenants.

Roof Waterproofing Cost

The roof waterproofing cost for commercial buildings can vary widely depending on several factors, including the size and complexity of the roof, the type of waterproofing system used, the complexity of the installation process, and the contractor’s rates. 

Since commercial roofs are often much larger than residential roofs, the cost of waterproofing will generally be higher. Indeed, the total cost for commercial roof waterproofing can range from several thousand dollars to tens of thousands of dollars or more. 

Generally, the cost for a waterproofing membrane, such as a rubber roofing membrane, ranges from $4.25 to $14 per square foot.

By contrast, the average cost to waterproof a roof with a coating typically runs from $0.65 to $5.00 per square foot, with the average cost being $1,307.

Be sure to factor in the cost of labor, including possible repairs. If your roof has sustained damage or shows signs of wear, the contractor will need to make repairs before waterproofing the roof.

The specialists at Union Roofing have been assisting clients throughout PA and NJ for over 40 years, offering comprehensive, personalized commercial roofing services.

The type of commercial roof waterproofing services you need will depend on the specific condition and requirements of your roof. 

Some common services include roof inspection, repair, maintenance, and replacement. 

  • A roof inspection will allow a contractor to identify any existing issues, such as leaks or damage, then provide recommendations for repairs or maintenance.
  • Repair services are tailored to specific issues in your roofing system with the aim of preventing further damage.
  • Regular maintenance can help extend the lifespan of your roof and prevent future problems. 
  • If your roof is beyond repair, replacement may be necessary. 

Types of Roofs that can
Be Waterproofed

Most commercial buildings have a flat or low-slope roof, and it is crucial to waterproof them to avoid water damage and leaks that can compromise the building’s structural integrity.

Union Roofing offers high-quality waterproofing services for the following roofs.

PVC Roofs

PVC (polyvinylchloride) roofing is a single-ply membrane roofing system that is designed to be watertight and durable. However, over time, the PVC membrane can become damaged from standing water, which can cause leaks and compromise the roof’s integrity.

By waterproofing the PVC roof, a protective layer is added to the surface of the roof, which prevents water from penetrating the membrane and causing damage. This helps to ensure that the roof remains watertight and protects the building below from water damage.

Additionally, PVC roofing can be damaged by exposure to UV rays and weathering, which can cause the membrane to degrade and crack. Waterproofing the roof can provide added protection against these elements and extend the lifespan of the PVC membrane.

EPDM Roofs

Like the PVC roof, an EPDM (ethylene propylene diene monomer) roof should be waterproofed to protect it from water damage and leaks. 

EPDM roofing is known for its resistance to weathering and UV rays, but prolonged exposure to standing water can still damage the membrane and compromise the roof’s integrity, leading to leaks. 

Roof waterproofing adds a protective layer that prevents water from seeping through the EPDM roof, thereby safeguarding it against water damage. 

In addition, waterproofing provides extra protection against weathering elements, such as UV rays, which can degrade and crack the EPDM membrane, ultimately extending its lifespan.

TPO Roofs

TPO (thermoplasticolefin) roofing membranes are designed to be watertight, but they can develop seams and cracks that allow water to penetrate the roofing system. 

Moreover, exposure to UV rays and weathering can cause the TPO membrane to break down, making it more susceptible to leaks and water damage. 

By applying a roof waterproofing coating or membrane to the TPO roof, a protective layer is added to the surface of the roof, which helps prevent water from seeping through and causing damage. 

A little prevention by way of waterproofing can help extend the lifespan of the TPO membrane and safeguard the building below from water damage.

Modified Bitumen Roofs

Modified bitumen roofing systems consist of multiple layers of asphalt and modified polymers, which can become damaged over time from exposure to the elements. 

If the seams and joints in the roofing system become compromised, water can penetrate the roof and cause damage to the underlying structure. 

By applying a waterproof coating or membrane to the modified bitumen roof, a protective layer is added to the surface of the roof, thus preventing water from seeping through and causing damage. 

Roof waterproofing, then, not only ensures that the roof continues to perform correctly, but it also extends the life of the roofing system.
