Without adequate ventilation in the attic, hot air is trapped without. As a trusted Roofing Contractor in Elgin SC, we understand the importance of proper attic ventilation. The first sign of poor attic ventilation is when upstairs rooms have uncomfortable heat. Without adequate ventilation in the attic, warm air is trapped without fresh air entering.
Another way to determine if your attic has sufficient ventilation is to install a thermostat and control the temperature. This is a great way to see if the attic controls humidity well. By monitoring humidity levels, you can also determine the effectiveness of attic insulation and ventilation. Not only will it be difficult to keep your home cool in the hot summer months, but hot air is often accompanied by humidity.
Extra moisture can cause problems with mold and mildew, something that no one wants, so it's important to have enough ventilation in the roof
. Based on this calculation, you'll need at least 10 square feet of ventilation to properly release moist air from your attic and properly heat and cool your home.There's a lot of hot, humid air floating in the attic. If you don't want moisture to start to rot the wood and cause mold to form, here's the rule that contractors should follow to ensure adequate ventilation. When a lot of warm, humid air is trapped in the attic, that moisture will cause mold to grow. When you have adequate ventilation, this maintains airflow through the attic space to prevent moist air from staying long enough to cause problems. If you see signs of mold or mildew in the attic, it's possible that they're due to a leak or poor ventilation.
The discoloration may look very similar to that of mold, but the degree of progress of the discoloration can make the difference between replacing a few wooden boards and paying for a total roof replacement. If you notice that you have a few loose shingles, it may not be due to poor ventilation. However, if you see large areas where roof tiles are coming off, it's time to call an inspector. If they notice that the damage has started to demarcate the wood (that is, it has become too slippery and there is nothing left attached to it), the roof will need to be completely replaced.
Even if more ventilation grilles are added, you'll still see problems such as the tiles falling or loosening and increasing the chances of leaks.

Not only can they fix it, but they can also add a few years to your roof before you need a total roof replacement. If you notice moisture in the attic, such as condensation on the rafters or roof covers, this is most likely a sign that the roof is poorly ventilated. Caring for your roof and house this way is a great addition to any New Year's to-do list for home maintenance and is something to keep in mind all year long. Trapped hot air causes problems all year round, such as ice accumulations on roofs in winter and overwork in air conditioning systems in summer.
If this moisture build-up worsens enough, it can cause permanent damage to the roof and even to the interior roof, which can be costly to repair. Roofs that don't have adequate ventilation actually fail one of the purposes they were designed for: they help maintain the interior temperature. When ventilation grilles do not allow heat to pass through, premature damage occurs to the roof and wooden beams of the attic. The roof not only has to protect the house from inclement weather and precipitation, but it also has to let hot air escape in the summer months without letting it in so that the house is as energy efficient as possible.
It's a good idea to periodically check the condition of the attic space to make sure that moisture doesn't build up anywhere and that it doesn't show any of the other signs that you don't have adequate ventilation in your roof. Moisture then builds up on the roof, behind dams, and under shingles, which can cause extensive roof damage and other interior damage. Poor roof ventilation is a problem that many homeowners probably don't consider, although it can cause serious problems inside their home. If ice accumulations are not removed, accumulated ice and water can seep into the roofing system and cause tile damage, roof leaks and even damage structural in housing.
Roof ventilation is an intake and exhaust ventilation system that provides air circulation that keeps the interior of the house pleasant and comfortable.
