Good Roofing in Austin: Skip the Overheating!
All good roofing Austin based is going to deal with one essential aspect: overheating! Anyone who has been in an attic knows that they can get hot- and anyone who lives in the Austin area knows that we can take hot to an entirely different level. The issue is that if the heat in the attic is allowed to sit it can conduct heat into the house or, at the very least, prevent heat from leaving the house.
The most economic and simplistic answer to this problem is to ventilate your attic so that you can move air through the space and reduce the temperature. Most homeowners already own a building that has a passive attic ventilation system. This often comes in the form of a ridge vent at the peak of the roof with gable vents at the end of the roof. There can also be a combination of soffit vents in the eaves of the roof. Older homes might also have turbine or roof vents that penetrate the roof as an easy fix for older roofs.
This may sound great- roofing with built in overheating prevention! The issue with many passive vents is that they require some sort of driving force, such as wind or a temperature difference, to move the air. In Austin, the hottest days are often the stillest days, with little to no wind. Temperature differences do not push out much energy so it can be very slow. Just when you need good ventilation, the vents work least effectively! All good roofing in austin will make ensure that your house has proper ventilation when you need it the most.
Many roofing contractors will be able to advise you when it comes to adding sufficient ventilation to your particular home. Some homeowners decide to add an additional attic fan. Attic fans are usually roof mounted or gable mounted and work by drawing air out of the attic. They rely on existing passive vents to supply cooler, outside air to replenish the air that they are pulling.
There are some unfortunate drawbacks to attic fans. First of all, an attic fan does not exhaust the heated air from the living space. A gable ended mounting system will only work if there are already existing gable vents, which many homes do not have, and a roof mounted attic fan is difficult to install without detracting from the home’s overall appearance.
In response, some homeowners opt for whole house fans that are mounted into the attic floor and that push hot air out through passive vents and then bring cool air in through the house. There is an additional advantage as it directly cools the inside of your home which, in turn, enhances the comfort level for your family. Whole house fans traditionally require 3X as much airflow as their square footage- which can be quite a bit of air flow. Fans this large can be loud and suck up a lot of power. You will need sufficient passive vents to keep up with that amount of air flow.
Whatever your decision, it is important to talk to your roofing contractor about ventilation options before completing any long term project on your roof. It will keep your house cool and save you money in the long run!
