Benefits of having roof vents
Roof vents play an essential and crucial role in air conditioning, and more so, it prolongs the lifespan of the roof by reducing the heat. Installing a roof is much more than just putting the shingles on but also involves the application of the roof ventilation aspect due to a variety of reasons.
The heat on your roof may get trapped inside the attic (roof void), especially during the summer season, which makes the attic (roof void) feel as if it were an oven, heating the rest of your house and making it feel very uncomfortable. When the attic (roof void) heat seeps into your house or home, it makes the room too to be less comfortable, which in turn causes the air conditioning system to run all time-nonstop. Proper ventilation breaks this cycle and removes the accumulated heat to make your home more comfortable and cool to live in. Besides these significances, roof vents have some more advantages. These are some of the common benefits of roof vents that are important for your knowledge.
The efficiency of the available energy increased since the temperature of the attic (roof void) is lowered. It means that hot air is not permitted into your home and therefore ensuring an efficient and regulated amount of energy. Roof vents also keep ensuring that the air conditioner does not keep running for long and often, which in turn reduces the costs and ensures that the air conditioning system lasts longer in an effective manner without frequent failures. They help to keep each room of the house at a similar temperature so that you do not have to turn up the cooling and heating systems to regulate the temperatures of particular rooms.
Proper roof vents also preserve the insulation through prevention o ripples form the condensation that may be caused by vapors trapped form the different home appliances. Proper roof vents that are well placed also prevents the damage of your house’s wood framing by preventing the trapped moisture that can come into contact and damage the wood frames of your home. During cold seasons, the roof vents play a crucial and vital role in maintaining a cold roof system through a mixture of the cool outside air with the attic (roof void) air that allows less melting of the snow on the roof of your house. This, in turn, helps to avoid the damaging of the ice damming. During hotter seasons, on the other hand, proper roof ventilation expels the hot air to maintain cool temperatures. Vents, therefore, plays a significant role, regardless of the given climatic conditions.
Prolongs the life of your roof
May Your Roof Live Longer
The other common advantage of the roof vents is that it helps to extend the lifespan of the roof, and maintains it in good condition throughout this lifetime. It works in a way that the ventilation saves your shingles and therefore extending the life of the roof, whether original or replaced.
It is common to see icicles building up on the edges of the roof and gutters of your house. This build-up is referred to as Ice damming. It may have significant damage to your roof and the edges of your roof. This might be hard for you to notice because it is a gradual process that takes time, and by the time you start to notice, your roof might be damaged already. Ice damming happens when the heat from the inside of your attic (roof void) mixes up with the heat from the sun and melts the snow or ice on your roof, warm roof. The resulting water runs to the edge of your roof and begins to freeze again at that point, which builds up at the edge of the roof. This can back up underneath or behind the roofing materials, which can cause damage to the whole roofing system, the attic (roof void), and even the walls of the house.
Proper roof vents come in to help the warm air escape before it gets a chance to melt the ice and snow on your roofing system. A well-ventilated roofing system is straightforward to observe in the winter season. You still observe the snow on the roof, but there is not an icicle any is in sight.
The ventilation is a benefit to the roof also in the hotter summer seasons. When the temperatures in the outside rise, the temperature of your roof is nearly double the outside temperatures. The hotter roof over an attic (roof void) that is poorly vented translates to a sweltering attic (roof void) because the unventilated and poorly ventilated attic (roof void)s do not have an escape route for the accumulated heat that may build up. This damages the shingles from both the inside and out, which in turn damages the roofing system of the house and eventually reduces its lifespan. Thus making you replace or repair it often-all this costs money and other resources and denies you the comfort you need while at your home or house.
A proper roof vent allows the hot air to escape and therefore keeps your shingles and roof safe from the stated damages and keeps the attic (roof void) cooler. That is how a proper roof vent helps to prolong the life of your roof, both in the cold winter and hot summer seasons.
Conclusion
A proper roof ventilation system is therefore appropriate and vital towards maintaining a cool and comfortable environment for you to live in. Furthermore, you have clearly understood its significance in extending the lifespan of your roof and keeping it in good condition.
