Experience Matters

With over 35 years of experience, we know the importance and value that comes with attic ventilation. We have seen the damages and dangers firsthand when attics don’t receive the proper ventilation. With our team, we can assist you with choosing and installing the right roof ventilation product, so your home can breathe as it should.

Proper Attic & Roof Ventilation

Proper ventilation is a critical factor in extending your roof’s lifespan. In winter, ventilation reduces ice damming and condensation. In summer, it is used to expel trapped hot air. However, you need a balance of intake and exhaust vents to ensure proper airflow. We offer a variety of ventilation systems to assist with your ventilation.

Our Services

Intake Ventilation

Making the Smart Decision

With so many roof and attic ventilation products available, each with their own pros and cons, it can be difficult to choose one for your property. Soffit vents, for example, allow an easy flow of air into the attic while ridge vents allow warm moist air to exit. Most importantly, as long as you have proper attic ventilation, you can protect your home. Our expertise in roof vents means we can help you decide which product works best for you.

Why Is Attic Ventilation So Important?

Attic ventilation might not receive as much attention as flashy home upgrades such as new hardwood flooring or bathroom renovations, yet its significance should not be underestimated. A properly ventilated attic plays a crucial role in preventing mold growth both within the attic space and in the living areas below.

Additionally, adequate attic ventilation helps expel hot air during warmer seasons and minimizes the formation of ice dams and ice sheeting in winter. While all houses with attics should already meet basic ventilation requirements according to building codes, it’s advisable to go beyond these minimum standards to ensure optimal long-term house maintenance.

To comprehend the importance of attic ventilation for your home’s safety and functionality, it’s crucial to grasp its fundamentals. Typically, intake vents are positioned on the lower sections of the roof, such as under the eaves. However, some homes may feature shingled intake vents lower on the roof or gable vents high on the sides. They allow air to flow into the attic space.

Moreover, a well-designed attic ventilation system includes exhaust vents near the roof’s peak. These vents facilitate the escape of hot air rising to the roof’s highest point. During summer, cool air enters through intake vents while hot air exits through exhaust vents, maintaining a balanced attic temperature.

In winter, it might seem logical to close vents, but it’s advisable to let cool air in through intake vents to regulate attic temperature. Excess attic warmth in winter can cause snow on the roof to melt during the day and freeze overnight, leading to ice dams in gutters and on the roof. This can lead to leaks, mold and mildew growth, and structural failure.

Venting With Soffits

Ventilation through soffits is a common method used to introduce fresh air into the attic. Soffits, located beneath the house eaves or roof overhangs, often feature individual vents spaced every few feet or a continuous perforated soffit spanning the wave’s length.

This approach is effective in maintaining attic airflow and is inconspicuous, blending seamlessly with the home’s exterior. However, inexperienced DIYers may inadvertently block soffit vents when insulating the attic, rendering them ineffective. To prevent this, it’s essential to avoid placing insulation over these vents during attic insulation projects.

Venting Without Soffits

For homes with narrow eaves unsuitable for soffit vents, alternative ventilation methods such as gable venting or shingle venting can be employed. Gable vents, positioned high on gable roofs, serve both as intake and exhaust vents, enhancing attic airflow.

Meanwhile, homes lacking gable roofs or adequate space for soffit vents often utilize shingled intake vents or roof edge vents positioned near the roof’s bottom. These vents, designed to blend with surrounding shingles, can be installed during roof installation or replaced during roof shingle updates to ensure optimal attic ventilation.

Exhaust Vents

Exhaust vents play a crucial role in attic ventilation by allowing hot air, which rises to the peak of the roof, to escape. While cool air typically enters through intake vents, hot air exits through exhaust vents, with gable roof vents being an exception. Various types of exhaust vents are commonly used, including:

  • Ridge vents
  • Static vents
  • Turbine vents
  • Powered vents

Ridge vents are popular due to their ability to blend seamlessly with the roofline. They run along the entire length of the roof ridge and consist of perforated vents covering a narrow gap in the sheathing.
Static vents are passive exhaust vents that feature raised square or circular coverings over openings in the roof. Perforated vents around the gap between the opening and the covering facilitate the exit of hot air.
Turbine vents operate similarly to static vents but incorporate an enclosed fan powered by wind. Even a gentle breeze causes the fan blades to rotate, aiding in the removal of hot air from the attic.
Powered vents, powered by electricity or solar energy, are another option. They automatically activate when the attic temperature reaches a predetermined level, effectively expelling hot air from the attic space.

Venting Finished Attics in Calgary

Ventilating a finished attic requires careful consideration to avoid issues like mold, rot, and ice damage. Instead of using wall gable vents or roof vents, opt for rafter venting.

Rafter vents, also known as insulation baffles, are installed between rafters, creating a narrow gap for outside air to flow in from soffit vents. This air then moves through the rafter vents to the roof peak, where a ridge vent allows it to exit the attic space.

Properly executed, this ventilation system can remain hidden behind finished walls, preserving the clean appearance of the space while ensuring essential airflow.

A lack of airflow in your attic can cause problems in and around your home. It can reduce the lifespan of your roof, damaging shingles in the process. Condensation and moisture build-up can lead to the growth of mold and mildew in your attic and your insulation system. It can also lead to higher energy bills and costly roof repairs in the future.

It is best for your home to have both vents in order to obtain a balanced airflow through your home. Intake vents allow cool air to enter your home, while exhaust vents allow warm air to be expelled.
