How a Faulty HVAC System Can Impact Your Commercial Roof

How a Faulty HVAC System Can Impact Your Commercial Roof

July 10, 2023

Commercial roofing is an essential aspect of any business infrastructure, providing protection against external elements and ensuring the safety and comfort of occupants. However, many factors can compromise the integrity of a commercial roof, and one such factor is a faulty HVAC (Heating, Ventilation, and Air Conditioning) system. This article discusses how a faulty HVAC system can impact your roof and the steps you can take to minimize the risk.

Factors that Can Affect Your Commercial Roofing

Mistakes Made by Technicians

One of the common reasons for a faulty HVAC system’s impact on a commercial roof is the mistakes made during installation or maintenance by inexperienced or unskilled technicians. Improper installation techniques, such as inadequate sealing, improper fastening, or incorrect placement of HVAC components, can lead to leaks and damage to the roof membrane. Hiring a reputable commercial roofer near you with experience in HVAC installations is crucial to ensure the system is installed correctly and does not compromise the roof’s integrity.

The Impact of Pooling and Condensation

Pooling of water and condensation can occur when the HVAC system is not properly designed or maintained. Improper drainage or inadequate insulation can lead to the accumulation of water on the surface, causing the roof membrane to deteriorate over time. The constant exposure to moisture can result in leaks, mould growth, and structural damage to the roof. Regular HVAC system inspections and maintenance, including checking for proper drainage and insulation, can help prevent these issues.

Effects of Faulty HVAC Unit Installation

When installing HVAC units on a commercial roof, it is crucial to consider the load-bearing capacity of the structure. The weight of the units, especially in large commercial buildings, can exceed the roof’s capacity if not properly assessed. Overloading the roof can lead to sagging, structural damage, and even roof collapse. Hiring a professional commercial roofing company that understands the load requirements and can reinforce the roof structure if necessary is essential to avoid these risks.

Excessive Foot Traffic

Commercial buildings often have rooftop HVAC units that require regular maintenance and servicing. However, the constant foot traffic from technicians accessing the units can cause damage to the roof membrane. Every time someone walks on the roof, there is a risk of punctures, tears, and other forms of damage that can compromise the roof’s integrity. Minimizing foot traffic and implementing protective measures, such as walkway pads or designated access points, can help reduce the risk of damage.

Adding Extra Units

As a business expands or undergoes renovations, additional HVAC units may be installed on the roof to accommodate increased heating and cooling demands. However, the haphazard addition of extra units can put undue stress on the roof structure and lead to leaks and other damage. It is best to consult an experienced commercial roofing contractor who can assess the roof’s load capacity and recommend appropriate measures to support the additional units without compromising the structural integrity.

The Vaporizing System is Not Working Correctly

HVAC systems often include a vaporizing system that releases moisture into the atmosphere. If this system malfunctions or is not working correctly, excess moisture can build up in the roof insulation, leading to moisture-related issues. Regular maintenance and inspections of the HVAC system, including the vaporizing system, are necessary to ensure proper functionality and prevent moisture buildup.

How to Minimize Risk

To minimize the risk of a faulty HVAC system impacting your commercial roof, consider the following steps:

  • Hire a reputable commercial roofing contractor for HVAC installations.
  • Ensure proper drainage and insulation to prevent water pooling and condensation.
  • Assess the load-bearing capacity of the roof structure before installing HVAC units.
  • Minimize foot traffic on the roof and implement protective measures.
  • Consult with a professional roofing company before adding extra HVAC units.
  • Regularly maintain and inspect the HVAC system, including the vaporizing system.

Why You Need a Roofer Onsite When Installing Your HVAC System

Prevent Punctures

A commercial roofer can ensure that no punctures or damage occur to the roof membrane during the installation process. They can provide guidance on proper techniques and precautions to prevent roof damage.

Ensure Proper Installation

Commercial flat roofers can collaborate with HVAC technicians to ensure the installation is done correctly without compromising the roof’s integrity. They can address potential issues and provide solutions to maintain the structure’s watertight seal.

Secure Fasteners

Rooftop HVAC units must be securely fastened to comply with local building codes. A commercial roofing expert can ensure that the necessary code-required fasteners are properly installed, providing structural stability and preventing damage to the roof.

3 Things to Keep in Mind

When installing or maintaining an HVAC system on a commercial roof, there are a few key factors to keep in mind:

Determine the System Capacity

Assess the heating and cooling requirements of your commercial building to determine the appropriate HVAC system capacity. Oversized units can put unnecessary strain on the roof, while undersized units may not provide adequate climate control.

Can Your Roof Support the System?

Before installing an HVAC system, consult a commercial roofing contractor to ensure your roof can support the additional load. Reinforcements or modifications may be necessary to ensure the roof’s integrity.

Ensure Envelope Integrity

The envelope of your commercial building, including the roof, walls, and insulation, must be adequately sealed and maintained to prevent air leakage. A well-sealed envelope will optimize the efficiency of the HVAC system and minimize its impact on the roof.
