5 Reasons Why Proper Roof Ventilation is Critical
You may not give much thought to the amount of ventilation your roof gets, but as a homeowner, you should. From mold and mildew growth to risk of ice dams, there are many negative consequences to improper roof ventilation. Today we’ll go over some of the tell-tale signs that your roof ventilation may be failing. In the event you notice any of these signs, hiring a DC roofer is an important first step in identifying the source of the problem.
Signs of Inadequate Roof Ventilation
Without proper ventilation in your attic, the following can occur:
1. Mold and Mildew Growth
This poses the greatest health risk to your family. Without proper roof ventilation, mold and mildew can grow unchecked, leading to health issues for all occupants. In addition to the health consequences, it can be unsightly to see, especially if you use your attic frequently.
Mold remediation services will be needed to safely remove the mold, as the spores can get into the lungs if breathed in. Such professionals will have to first kill the mold then remove the affected areas, such as wooden boards and joists. This can get expensive, so the best approach is to prevent the growth in the first place.
With proper roof ventilation, air is allowed to circulate, keeping hot, humid air out. Mold will thrive in humidity, so removing that type of environment means mold is much less likely to grow there. You’ll need to ensure you have enough exhaust and intake vents to keep the space cool and dry.
Your Maryland roofer will be able to spot the signs of poor ventilation and make the proper adjustments. On a related note, improper roof ventilation can lead to condensation, which can rust any metal items in your attic space, such as metal straps and nails.
2. Risk of Ice Dams
Ice dams commonly form in winter, especially for homes that have ventilation issues. Proper ventilation keeps air circulating throughout the attic, which in turn ensures your roof remains at a consistent temperature. Without that ventilation, hot air will become trapped at the top, warming your roof. As ice and snow melts, it freezes at the edges of your roof where it is colder.
Ice dams can be dangerous, too, so don’t attempt to remove them on your own. Adding enough ventilation will ensure you don’t get ice dams, or if you do, they will be very minor.
3. Extreme Temperatures
If you have cold or warm spots in your home, improper ventilation may be to blame. You need enough ventilation in your home to keep a consistent temperature throughout the interior of your home. Drafty spots in winter and warm spots in summer almost always indicate lack of ventilation. Inadequate insulation can also be the culprit.
4. Water Damage
Mold and mildew aren’t the only thing that can happen when there is too much humid and moist air in your attic. All that moisture can rot your roof’s wooden decking, leading to the need for structural repairs. Water can also leak into the living spaces below, resulting in ceiling and wall stains. In addition, moisture can invite pests to live in your attic, as many of them prefer damp, dark areas where they won’t be disturbed.
5. High Energy Bills
If you have noticed higher than usual energy bills, yet you’ve ruled out any obvious causes, lack of ventilation in your home could be the blame. As we said above, proper ventilation helps to maintain consistent temperatures throughout your home. When your HVAC system has to constantly kick on to keep you comfortable, this causes spikes in your energy bills. It also strains your HVAC system, resulting in a shortened lifespan and premature replacement.
