Stay on Top of Your Roof Ventilation

We may not often think about it, but how air and water escape a structure is incredibly important to the overall function of that structure. As with any enclosed space, toxic gases—including even something as simple as carbon dioxide, which you exhale when you breath—can accumulate in a poorly ventilated structure. It’s the same reason you don’t warm your car up in the garage: the ventilation simply isn’t adequate to handle the exhaust and you could severely harm yourself if you try it. The same principle is true in any structure: it needs to be ventilated to ensure safety.

In Minnesota, ventilation can be complicated, as it must allow air to escape without compromising the integrity of the insulation that keeps the structure warm in the winter and cool in the summer. In most cases, this is accomplished through rooftop ventilation. Special ducts are constructed in the walls, which lead to the roof, in order to facilitate the release of gases and unwanted air. In terms of HVAC, these rooftop ducts allow for escape of warm air when the building needs to be cooled and cool air when the building needs to be warmed. An efficient system is more energy efficient and financially affordable.

Ventilation Needs in the Twin Cities

Not all air vents in the same way and from the same place. For example, any HVAC system requires its own ventilation system. Usually this is a closed system, over which the HVAC system will have total use and control. It might throw off the system, for example, if cooking exhaust was mixed in, therefore raising the temperature and volume of air. In other words, there are certain systems that require their own ventilation, and most of that is accomplished through the roof.

You might require rooftop ventilation for some of the following systems:

  • HVAC: Your heating, ventilation, and air conditioning system requires its own exhaust system. This exhaust is generally vented through the roof. And in order to ensure the efficiency of your system, these vents must be covered (to prevent water damage or drainage issues) and clear and operating. Sometimes this means replacing the duct or the vent and sometimes it means cleaning the system.
  • Cooking Systems: Many commercial structures have a designated cooking area, whether a common room in community buildings or a cafeteria in office buildings. Sometimes, in apartment buildings, you’re talking about dozens of designated cooking areas. Cooking requires ventilation, and that usually means rooftop ventilation (as hot air tends to rise, this is the most efficient evacuation method).
  • Water-based Systems: Whether its your humidifier or your bathroom fan, any place there’s water, you want strong rooftop ventilation. In the case of the bathroom fan, you’re mostly trying to clear out moisture created by a shower—and because showers are usually on the warmer side and because hot air rises, this is usually the most effective means. But moisture will slowly degrade and possibly destroy your structure if it’s not vented out, costing you a lot of repair money in the long run.

How Much Does Roof Ventilation Cost?

When it comes to commercial properties, it’s difficult to nail down an exact number for roof ventilation installation or repair. There are many variables, such as the slope of the roof (though, most commercial structures tend to have relatively even roof lines, especially in Minnesota) and the scope of the project. Installing several dozen rooftop vents in an apartment complex will be more costly, for example, than installing one at a retail shop. That said, commercial properties have the benefit of ordering in bulk, meaning that an experienced and reliable contracting company, such as Exterior Contracting, Inc., can find efficiencies that cut down on costs.

When we prepare our estimate, we generally look at the following features:

  • Scope of the project
  • Timeline of the project
  • Residential impact (will we need access to residential units, for example)
  • Square footage
  • The number of units
  • The duration of the ventilation (that is, how far away from the ground is the roof)

A Great Option for Commercial Roof Ventilation in the Twin Cities

There may be other factors that we take a look at, including the overall complexity of the project at hand. However, it’s important to note that, especially for large commercial structures or, for example, expansive apartment complexes, roof venting is a way to prevent damages and expenses in the long run. It safeguards you investment in property and it keeps your structure functioning as optimally as possible. In other words, the more efficient your commercial structures are, the more money you save and the more peace of mind you have.

If you’re interested in repairing or replacing your rooftop ventilation, it’s better to get that process started as quickly as possible. So contact Exterior Contracting, Inc., to set up a consultation and get a quote right away.
