In a past blog, we discussed the importance of attic ventilation for your home. Proper ventilation serves two main purposes: in the summer it allows hot air that has collected at the roof deck to escape out of the attic, and in the winter it thins and removes moist air before it can lead to damage. Here are the reasons ventilation matters in every season.
In the summer, good ventilation keeps the attic cooler, which means a cooler home overall. Moisture trapped in an overheated attic can cause damage to roof decking and shingles, leading to warping and premature deterioration. Proper ventilation maintains a constant temperature in the attic which prevents the formation of ice dams and icicles in the winter.
There are several choices in roofing ventilation, and each has its pros and cons.
A ridge vent is ideal for most homes because it is positioned along the entire peak of the roof. In addition to allowing for excellent exhaust of heat and moisture year-round, ridge vents blend in nicely with the roof line. Research has proven that ridge vents with external baffles, used in conjunction with undereave venting, are the most effective and efficient attic ventilation system you can install.
