Constructing and maintaining a commercial building is a complex process that requires different trades to work together to ensure a safe and accurate structure. One vital, but often overlooked, professional relationship on these projects is between the mechanical contractors and roofing contractors.

Without their collaboration, the commercial building and roof could be doomed before it’s ever finished.

What are Each of their Roles?

First, it’s important to understand each contractor’s specific role in the commercial building process. Mechanical contractors are responsible for the heating, ventilation, and air conditioning for a space, hence the commonly used term HVAC contractors. This includes tasks like running the ducts, installing the main units, and ensuring all items are up to applicable state and local building codes.

A commercial roofing contractor’s job is a little more obvious. They’re responsible for the design and installation of one of the most important parts of the building – the roof. They focus on aspects like energy efficiency and drainage and are experts in both regulations and the best materials to withstand the weather and other conditions.

Why are Commercial Roofers So Important?

Their roles may seem unrelated, but have you ever noticed that a majority of commercial buildings have their main HVAC units on the roof? This design is used for a few reasons.

By installing all of the equipment on the roof, it allows for easy access for maintenance and repairs with minimal disruptions to the operations of the building. Additionally, the building itself remains quieter as the noise travels upward. Further, having the bulky equipment on the roof allows for the indoor spaces to be used for other needs.

Roof placement also boosts curb appeal, especially for businesses that want to represent a clean and luxurious storefront. Finally, it actually can protect customers and employees of the building by eliminating the possibility for access.

While these are amazing benefits, HVAC systems weigh a lot, which is major stress on the structure. HVAC contractors need to ensure that the roof can withstand the weight and layout of the HVAC system itself. Otherwise, you’re looking at potentially weakening of the roof over time, leading to a potential fall-through disaster.

Additionally, the design and make of the roof can greatly affect the energy efficiency of the building. That means that the better a roof is installed and maintained, the less work the HVAC system may need to do to maintain temperature.

Think about it this way. If a roofer left a giant hole in the top of the building, the HVAC system is going to work super hard to keep it warm in the winter. That overwork can lead to additional maintenance or even costly repairs.

While an extreme example, any issue with efficiency can lead to major heating and/or cooling costs over time that could have been avoided if the roofing and HVAC contractors agreed on specifications.

Finally, the two trades also work together to fight against moisture. Roofing contractors will not only have the expertise to ensure the pitch and angles are appropriate for drainage of rain or snow but can also help HVAC contractors ensure any potential moisture from their unit(s) is diverted from the building to avoid moisture damage.
