When you need a good roof, one of the most important factors to consider is the attic. The life of your roof is affected by the way the attic breathes and how it is vented. However, many builders overlook its importance.
The attic regulates the movement of heat in and out of your roof depending on the season. It also supports the roof of your house. Poor ventilation may lead to high temperatures up there during the summer, causing premature aging of the shingles. It may also produce warmth during winter causing dampness.
Do you have difficulties in regulating the temperature in your house? Are your electricity bills always high? This is the best time to ask whether your attic is ventilated properly.
How to Avert Problems in the Attic
1. Ensure you have sufficient ventilation. A ridge vent at the rooftop and soffit vent at the front eave are recommended for the gabled roof. In case your house has ridges, soffit, and gable vents block them off as they affect the free movement of fresh air in and out of the attic. For a hip roof, ensure you have ridge and soffit vents.
2. Do not obstruct the soffit vents. Ensure that the debris, paints and attic insulation do not clog the soffit vents. Baffles should be installed to stop the insulation from interfering with air flow.
3. Soffit vents are more effective when they are below the gutters than when they are above.
4. Bathroom exhaust fans should not vent into the attics. This may increase the moisture levels in that region, which is dangerous for your roof too.
5. Rafters and sheathings should not block the vents of your attic.
6. The attic floor should have sufficient insulation. The insulation should be 12 or more inches. This will prevent the escape of the heat into the space, which makes your heating system to overwork.
7. Attic access areas should have good insulation. Lack of proper insulation will increase the temperatures in the living room, thereby raising heating bill.
8. Heat escape into the attic should be avoided by sealing gaps in any vent or flue pipes that go through its floor.
Why Attic Ventilation is Vital to Your Property
Ventilation is a system that allows free movement of air, in and out of place. Effective attic ventilation is important to your property in the following ways.
1. It allows movement of cool and fresh air into the attic. It also allows the escape of hot and moist air which is important in the regulation of temperatures in the living room.
2. An effective attic ventilation is especially important during summer. During the hot months, the attics heat up very much. Improper ventilation may lead to a build-up of heat and moisture, making the process of cooling difficult. It may also result in high temperatures in your room.
3. High levels of moisture and heat in the attic cause a lot of damage. These conditions damage the shingles, wood framing, and ceiling. The paints and wallpapers are also not spared by the high humidity. Effective ventilation is crucial in addressing this problem.
4. Effective attic ventilation reduces cooling energy consumption. During the summer, air conditioners and fans are used to make the living rooms comfortable. An improper ventilation forces the cooling system to overwork leading to an increase in power bills.
5. During winter, there is a high moisture build-up in the attic from appliances, showers, and cooking among others. Improper ventilation leads to a collection of moisture. It then condenses soaking the insulation, thereby reducing the energy efficiency in your property. Excess moisture may cause rotting or attract termites.
6. Improper ventilation may also cause ice dam formation during the cold weather. The dam is formed when the snow and ice melt when the attic warms and then freezes again at the gutters and eaves. The water may cause damages to the walls and ceilings. With proper ventilation, the process of snow formation is slowed down thereby, reducing the chances of ice dam formation.
7. Improper ventilation may lead to condensation in the attic. This may cause the waviness and buckling of the deck and the shingles. The roof deck may rot, reduce its capacity to carry loads. The nails may lose their holding capacity.
For a ventilation to give the best results, there is a need for a particular type of air movement. Efficient attic ventilation is tasked with a continuous, high volume of air movement. The most important reason for venting an attic is to remove the wet hot air found there. This is because that air may break your roof or lead to a severe mold problem which is very expensive to rectify.
So, if you want a warm house in winter and a cool house in summer, consider a well-ventilated attic. It may lead to the preservation of your property and reduced electricity bills.
