Having proper ventilation within the home is very important. As well as keeping air flowing throughout the house during the year, it helps prevent a buildup of moisture which can result in mold. Having mold in the home can cause issues with breathing in some people due to the number of spores it releases into the air. So by having good roof vent installation, you are protecting both the home and family.
Water vapor in the home can come from a number of places, such as the cooker, microwave kettle, shower, and also from things like fish tanks. As most homes are kept warm, having a higher humidity level inside the home is normal. It is when this warm air comes into contact with cooler surfaces that causes condensation to form. On top of that, if the warm air in the home gets into the attic during the cooler months of the year, it can form water droplets and damage the building and insulation.
The opposite is true during the hotter summer months, if you have black roofing then your attic will be absorbing heat, and so the air between the roof and your ceiling can easily reach temperatures over 100 degrees. This can keep the inside of the home warmer than it should be, so if you are using air conditioning then you are wasting a lot of electric.
Most modern homes are constructed with adequate roof vent installation, but older homes tend to have limited ventilation, or none at all. Most modern vents consist of two types of ventilation. Intake vents are used to allow air to get into the attic, and they are placed along the soffit. While in the upper third of the roof area, exhaust vents will be placed. Building contractors will often tell you that the air in the attic needs to be circulated and replaced every six minutes to maintain a constant temperature, and control moisture levels.
There are many different types of roof vent installation available:
• Static Vents: You need a number of these installed to help keep the airflow consistent, but they are prone to leaking.
• Gable Vents: These are installed in the gable area of the roof, and although the easiest to install, they are also the less effective.
• Circular vents: A hole is drilled into the soffit, and the vent is inserted. They can be anything between 1” to 8” in diameter.
• Ridge vents: Go along the top of the roof replacing the ridge shingles.
• Power Ventilators: These are the most effective of them all, however, as they are electric, they do cost money to run. However, if they are preventing the buildup of moisture and mold, it can be money well spent. You can install power ventilators that use only wind power, but the downside is that they do not work if there is no wind.
Which is the best roof vent installation for you will depend on how big the attic area is, where in the country you live, and how bad your moisture problem is now, but it is a good idea to have some form of ventilation.
