Ridge Vs Gable Options for Metal Roof Venting Solutions

There are a few key components to be considered when it comes to any metal roof setup, and the vent format you use is definitely high on this list. Among a few types of vent that can be used for a metal roof, two of the most common and popular types are ridge vents and gable vents.

At Mid Michigan Metal Sales, we’re proud to offer a huge range of metal roofing supplies for clients around Michigan, from metal roofing shingles to metal roofing panels and more. Here are some basics on why roof vents are important for metal roofs, plus some simple qualities of ridge and gable vents and some tips from our professionals on how to choose the ideal vent option for your metal roof and property setup.

Why Metal Roof Vents Matter

There are a few key reasons why metal roof vents are essential for any property with a metal roof installed. First and foremost, proper ventilation is crucial for maintaining the integrity and longevity of your metal roof. Without adequate ventilation, hot air can become trapped in the attic space, causing damage to the roofing materials and potentially leading to costly repairs or replacements down the line.

Additionally, metal roofs are known for their energy-efficient properties, as they reflect heat from the sun rather than absorbing it like traditional asphalt shingles. However, without proper ventilation, this energy efficiency can be compromised as heat becomes trapped in the attic space and increases indoor temperatures.

There are two primary vent types used for metal roofs today: Ridge vents and gable vents. Let’s go over some basics on each.

Ridge Vents

Likely the most efficient vent option available for the majority of metal roofs, ridge vents refer to a setup where air is drawn in through soffits, then is released again at the ridge of the setup. This is meant to avoid heat buildup and condensation issues that can be problematic for metal roofs.

Ridge vents have a few excellent qualities:

  • Simple installation: Because ridge vents have no moving parts or electrical needs, they are relatively easy to install. They don’t require any additional structural changes or modifications to the roof.
  • Cost-effective: As mentioned, ridge vents are often considered one of the most efficient and cost-effective vent options for metal roofs. They typically have a lower upfront cost compared to other ventilation systems, making them an attractive option for homeowners on a budget.
  • Low maintenance: Due to their simple design, ridge vents also require minimal maintenance. Once installed, they can continue to operate effectively without much intervention.
  • Aesthetically pleasing: Ridge vents blend in seamlessly with the overall look of a metal roof. They sit at the peak of the roof and are not visible from ground level, providing a clean and uniform appearance.

Despite these advantages, there are also some limitations to ridge vents that homeowners should be aware of before choosing this type of ventilation system. These include:

  • Limited air flow: Ridge vents rely on natural convection currents to draw hot air out of the attic. This means they may not be as effective in areas with low wind speeds or during periods of still weather.
  • Ineffective for certain roof types: While ridge vents work well with metal roofs, they may not be suitable for other types such as shingle or tile roofs. Shingles can block the airflow from the vent, reducing its effectiveness.
  • Possible fans or other equipment: For especially large metal roofs, additional fans or other equipment may be needed to assist with air flow and ensure proper ventilation. This can add to the cost of installation.

Gable Vents

Gable vents, on the other hand, refer to holes cut in the gable of the property to allow hot air to vent out. A cover will be placed over the hole that is cut, both for aesthetic purposes and to ensure airtightness.

Gable vents are a popular choice for homes that have attics, as they are designed to work alongside any existing attic ventilation. They can be an effective way to reduce heat buildup in the attic, but may not be suitable for all roof types. It is important to consult with a professional before deciding on gable vents as your main source of ventilation.

In addition, there are certain property designs where gable vents can also be used alongside ridge vents. In these settings, the gable vent will be responsible for air intake, while the ridge vent will be used to expel air efficiently.
