There is a variety of roof ventilation systems used in construction today, depending on the type of roof of your house or structure. For those who are not professional Ross roofing contractors, the knowledge concerning this type of ventilation can be overwhelming, and it is easy to feel frustrated or confused about the whole affair. When and where to utilize ventilation, what kind is ideal for your roof, and even the logic for ventilation, may be lost on you? So, let us take a moment to talk about roof ventilation and how it relates to different types of buildings.
What is the Significance of Roofing Ventilation?
The basic idea behind roof ventilation is temperature management. It helps to avoid ice jams in cold climates by keeping a cooler roofing temperature and also allows moisture to escape from conditioned living rooms through the attic. In warmer regions, effective ventilation allows solar-heated hot air from the attic to escape, lowering a building’s cooling burden and putting less strain on air-conditioning systems. Meanwhile, roof ventilation can potentially fulfill both functions in climates varying from hot to cold.
Roofing Ventilation Types
Depending on your area’s construction standards, you will probably need one square foot of vent area for every 150 square feet of attic space. Roofing ventilation is used not just to allow air to depart, but also to allow air to enter. There are several forms of ventilation, which we shall go through presently.
- Box vents are sometimes referred to as low-profile vents, louvers, flat vents, and turtle vents. Because they have no moving parts, they are referred to as static vents. A box vent conceals a hole in the roof and uses natural convection to circulate air. Box vents are adaptable, cheap, and one of the most prevalent forms of a roof ventilation system. They are available in a variety of colors and materials.
- Wind turbines are sometimes known as whirlybirds because, while they have moving parts, they do not have an engine and instead rely on wind to move. When the wind is blowing, these ventilation systems move more air than typical box vents.
- Power vents combine the advantages of box vents and wind turbines. Because they are motorized, they provide adequate ventilation regardless of the weather or wind conditions. They are quiet and efficient, although they are slightly more costly than box vents or whirlybirds.
- Ridge vents are a form of static vent system that is put along the ridges of roofs. They are meant to span the whole length of a roof’s horizontal ridge and integrate perfectly into the architecture of the roof, making them an appealing alternative.
- Off-ridge vents, like box vents, are static vents that are put over a cut part of the roof, generally near the ridge. Box vents, on the other hand, are square, whilst off-ridge vents are narrow and rectangular, and possibly the least effective of roof vents.
As you can see, roof ventilation systems vary and are intricate, so when deciding which system is ideal for your property, it is always better to consult with a knowledgeable roofing contractor. Your Ross roofing repair expert can advise you on which systems are ideal for your climate and even for the sort of roof you have.
