Importance of Proper Roof Ventilation

While a lot of property owners are aware of the perks of having good insulation, most of us fail to recognize that your roof ventilation also plays a great role in maintaining the condition of your roofing system. Because of this, DIY enthusiasts usually make the mistake of concealing over the vents below the eaves once they are mounting insulation. To know better, here are some facts about proper roof ventilation:

Avoid ice dam

Though they may appear to be aesthetic, hanging icicles along the roof edges aren’t something that property owners would like to see. This formation of icicles are indicators of Ice Damming—an issue that’s mostly linked with an attic with poor ventilation. When your attic gets too warm and retains hot air rising from below in wintertime, your roof will heat up. Eventually, this causes the snow above it to melt. After this, the melted water will trail down to the roofing edge and its gutter, where it’s particularly cooler. If this happens, the water freezes again and thy cycle will repeat until the ice dams are created.

Avoid moisture and mold damage

Condensation can be a major issue especially during the winter season when the warm air increases from your home interior and hits cold surfaces. Once your attic is not ventilated well, the moisture will eventually accumulate, which can result in stained ceilings, moisture, mold, and can even damage the structure of your trusses, rafters, and the roof itself. When this issue is neglected or attended in time, it can eventually require you to have your roofing entirely replaced, which can be too costly.

Prolong the lifespan of your roof

Your roofing will become heated on its interior surface apart from the exterior one when your attic overheats. As a result, this will result in your roof shingles and underlayment to crack much quicker and dry out a lot faster than you would expect, which leads to more repair work.

Help lower your electricity bills

During summertime and there is no circulation of air available, stagnant and hot air will build up under your roofing, which heats your ceilings and absorbs into your living area. Consequently, this makes your AC work double-time, consuming more energy, and increasing your utility bills.

The ultimate purpose of roofing ventilation

You might think that when you spend expense and time to keep heat in, you do not want cold air to blow into your attic via these vents. However, this is the most typical mistakes that homeowners tend to do. In fact, you need cold air to blow in your attic. If it’s cold outside, the main purpose of ventilation is to regulate a cold roof temperature to prevent ice dams developed by melting snow. Moreover, it’s used to vent any moisture that is moving from the conditioned living area to your attic. In warmer climates, venting is intended to release hot air from the attic and roof and to minimize the accumulation of temperature.
