  1. Importance of Ventilation for Metal Roofs

  2. When you need a new roof, there are plenty of things to consider—choosing the perfect color, selecting a material and style that works best for your home and personal taste, and even sticking to a particular budget. And while all of these decisions matter, there’s an even more important one to consider. What lies under your roof—the attic and how it breathes and is vented—can greatly impact the life of your roof system.

  3. Why it Matters A balanced attic ventilation system that consists of intake at the eaves, soffits, or fascias of the roof, and exhaust at or near your roof ridge, serves two important functions. First, it allows cool, fresh air to enter into the attic. Second, it allows hot, moist air to escape.

  4. Even though a balanced ventilation system in your attic is crucial for regulating temperature all year round, it’s especially important during the hot summer months, when the sun beats down on the roof and causes the attic to heat up even more. Improper ventilation can contribute to heat and moisture buildup in the attic and can even increase the temperature in your living space. Excessive heat and moisture can cause damage to shingles, wood framing, ceiling, siding, paint, and wallpaper.

  5. Another effect of improper ventilation is that it may increase cooling energy consumption. A hot attic in the summer will cause a rise in a home’s temperature—which homeowners will battle by blasting the air conditioning and fans to keep the living space comfortable. To keep up with the added heat, these units and appliances will need to work even harder to perform, which causes a spike in summer cooling costs.

  6. Ventilation is not just an issue in the hotter months of the year. During the winter season, appliances as well as showers, baths, cooking, and laundry can contribute to extra moisture build-up and water vapor in the attic. When an attic is not properly ventilated, this moisture collects on the underside of the roof. It then condensates and can soak the insulation and reduce your home’s energy efficiency. Excess moisture can also cause damage to the structure of the house, like rotting, and can even attract wood-eating insects like termites.

  7. If you are not sure if your attic is properly vented, or if you’ve had high cooling and heating bills in the past, now is the time to call a reputable roofing contractor in your area, who will check your attic and roof to determine that you have the proper amount of ventilation your attic requires.
