Poor Ventilation?

How to prevent roofing ventilation problems as your roof ages?


As a homeowner, you want to protect your home and everything inside it. A great place to start is to protect and maintain the health of your roof. When damage happens to the exterior of your home and especially your roof, it can have major repercussions that affect your home and your family. Noah’s Ark Roofing and Sheet Metal LLC wants to help homeowners prolong the health of their roof, and the best way to do that is by following proper roof ventilation practices. Roof ventilation is a system of intake and exhaust vents that provide air circulation to keep the atmosphere inside a home comfortable. Without the in and out passages involved in roof ventilation, hot air will get trapped within your home, causing a variety of problems for your roof. So what is the best way to help with this problem? Its simple, Your Licensed Contractor will more than likely choose from the list below.

  1. Natural Ventilation – Hot air rises within a home and creates pressure in the attic. If this high-pressure air is given an outlet to escape, it will automatically be replaced by cool, low-pressure air. By installing various types of roof vents, homeowners can take advantage of natural air flow to provide proper roof ventilation and keep the inside of the home comfortable. Natural ventilation can also be achieved through doors, windows’ and other gaps.
  2. Mechanical Ventilation – For some structures, it may be necessary to use a system of mechanical vents. This type of roofing ventilation requires a power source to provide constant air flow. Mechanical roofing ventilation options are necessary if the design of the roof doesn’t allow much air flow or the home is in an area without much wind. Improving your roof ventilation will help keep your roof and the rest of your home in prime condition. If you’re not following proper roofing ventilation tips, warm air will become trapped in your home and cause issues that can lead to costly repairs, which the Noah’s Ark Team will cover in the signs of poor roof ventilation.
  3. Maintaining your home’s roofing ventilation is especially important because we experience both extremely cold and hot weather. Roofing ventilation options should protect your home from each of these scenarios:
  • Hot air trapped in your home during the summer, making it difficult to keep your home cool
  • Trapped hot air causing issues like mold, mildew or ice dams in the winter.

Here are some signs of a poor ventilation:

Icicles & Ice Dams – When there’s snow piled up on the roof and you start to notice large ice dams forming along the roof, that means there’s a problem with the roof ventilation. Ice dams form when the roof is heating up, the snow is melting and then the running water is freezing once it reaches the edge of the roof. This is a major indicator of poor roof ventilation and can cause more serious issues and will cost you a pretty penny if not taken seriously.

Hot or Cold Areas in The Home – Have you ever felt a noticeable increase in temperature when you walk up the stairs or from room to room? This is another sign of poor roof ventilation. Extremely hot or cold areas in the home is another sign that your heating, cooling and ventilation systems are not keeping up with the demand.

Roof Leaks, Mold & Mildew If homeowners ignore the warning signs of poor roof ventilation, it can lead to serious problems later on for your home and your health. When your roof is exposed to water damage over time, or suffered major destruction from a bad storm, this can cause roof leaks. If these are not treated right away, the excess water in the home could create additional problems like mold, mildew and more.

Unwanted Pests Found Inside – Some roof ventilation issues lead to damage to the exterior of your home. If your roof, or gutters in the past, it could allow critters to find a way inside. Whether you have tiny insects that can creep in through tiny cracks and crevices, or squirrels and rodents that can scratch their way indoors, any of these unwanted pests could be an indicator that there’s an issue with your roof.

Noah’s Ark Strongly Suggests that you get these issues taken care of right away!
