Dallas Roofing: Article About Choosing The Right Ventilation
Dallas roofing companies appreciate the value of effective attic ventilation, and homeowners are often surprised at how important the ventilation is. The fact is that improper ventilation can lead to problems with mold, rot, and even damage to the shingles. Ventilation problems are typically addressed when a roof is replaced, but the fact is that these issues can be corrected at any time. Here is what homeowners should know about the different intake and exhaust options that are available to them.
Attic ventilation works based on the knowledge that hot air rises. Placing vents along lower areas of the attic allows the cooler air to come in and push the heated air out through an upper vent. The goal is to create a uniform airflow along the bottom of the roof sheathing.
Undereave vents and continuous soffit vents are placed in the soffits that overhang the home. When adding insulation to an attic, homeowners should take care not to block these vents with blown, rolled, or spray insulation. For homes that have a limited overhang, an edge or vented drip edge may be the best option.

These will pull air in from directly over the gutters and pull it into the attic along a continuous line.
Roof louvers, turbines, and gable louvers have been used for decades. They're all low cost options, but they also have the same drawback of exhausting the air through a very limited space. They can work effectively, but most homeowners choose to upgrade the exhaust when they have the roof redone.
Power fans are a popular choice because they pull air from all around the lower edges to one central point. This can be a great choice on a hip roof where there is angled roof sheathing on all sides. The top choice in the industry is typically the ridge vent because it creates a solid line of exhaust that balances nicely with the continuous intake points.
Finally, the ventilation system must be balanced. When the air movement is an equal combination of intake and exhaust, the result is steady airflow and effective ventilation. Otherwise, the air can still stagnate, and the homeowners may have problems with mold, frost, and overheating. Professional roofers can assess the ventilation needs of an attic and explain the different options to the homeowner. Getting the right ventilation in place is important for protecting the roof and keeping the structure dry and ready for use.
