Did you know your roof needs to vent although sometimes everyone needs to let off a little steam? Thankfully, it does not involve emotions and with things like plastic and metal roof venting is done.
However, in your roof the importance of proper venting cannot be underestimated. Damaging structural components of your home and reducing the life of your roof moisture and heat build-up can be caused by a poorly vented roof. Thus, proper roof ventilation systems are essential.
Use of Roof Vents
A roof vent plays several vital roles although it may not be a very attractive addition to your home's appearance:
Temperature regulation - in the hot months attic temperatures can be excessive without proper roof venting, and during cold times on the other extreme. To the various roofing materials these extremes cause premature aging is caused by these extremes.
Moisture regulation - in the attic excessive moisture build up would be resulted from the exposed underside materials of the roof and a non-ventilated roof. This could lead to deterioration, rot, and mold. You must also maintain adequate underfloor ventilation also.
Vents Letting Moisture In
Is a vent with all the emphasis on a well-sealed roof counterproductive? Where does attic moisture come from? To understanding roof venting both of these questions are key. First of all, to prevent moisture from going in roof vents are designed in such a way.
To keep snow, rain, other moisture, and sleet from entering these roof openings both the design of the attached shielding and vent help. Essentially, humidity in the air is the only type of moisture that from the outside should be able to enter a roof vent.
So where does that attic moisture come from? Due to the activities that take place the air condition is naturally moist in a normal home. To the warmth of bodies and appliances it is also subject. The result is through the ceiling and into the attic space moist, warm air then rises up. The result is moisture if it is cold outside, as than the air that comes up to meet it the roof, including the sheathing is colder. Rot and mold building up and destroying surfaces can be the result of this moisture. You will need to take measures for mould prevention.
This moisture can lead to issues. Warping, shifting and buckling are another common result of temperature and moisture extremes.
Types of Vents
Two types of vents are required by every attic space: to maintain adequate airflow exhaust vents and intake vents. While the exhaust vents are usually along ridge of the roof, or the highest point the intake vents are usually located on the eaves of the house.
On the market today there is a large selection of vents available. Few include power vents, Static vents, turbine vents, cupola vents, and soffit vents.
On a number of factors including the configuration of your roof, your attic size, the type of material your roof has and the common weather patterns to which the roof will be exposed, determining the types of vents you need will depend.
While others along with ridge venting use continuous soffit vents some people install some turbine exhaust vents or only a few eave intakes. Consulting with a qualified roofing specialist is one of the best ways to determine your venting needs. To help you make the right choice for your home he will have the knowledge needed.
