Roof venting serves two purposes for your Cincinnati area home. During cold weather, the primary purpose is to maintain a cold temperature on the roof to avoid ice dams resulting from melting snow. Proper roof venting allows for the removal of moisture that rises from the living space into the attic. When moisture accumulates in the attic, damage to the roof structures can occur. The second purpose is to vent hot air from the attic during the summer months and to lessen the load on air conditioning systems while making the living space more comfortable. Today’s Cincinnati Roofing blog post discusses ridge vents and how they help with proper roof ventilation.
Ridge Vent Systems
Air movement is the function of Ridge Vents when used in combination with Soffit Vents. Without these vents, hot air cannot escape the home because the hot air creates pressure preventing outside air from entering. Air movement is important for efficient attic ventilation. Ridge Vents create a continuous airflow along the underside of the roof and removes moisture and heat.
Removing heat is important because attic temperatures can be as high as 150 degrees in the summer. This highly heated air can damage shingles and structures and make cooling the home more costly. Heat and moisture combine to damage trusses, rafters, roof decking and shingles.
Since Ridge Vents work year round they will also prevent excess moisture buildup that can accumulate in the attic resulting in mildew, mold and wood rot. The moisture released from household activities will rise into the attic, and while this problem exists year round it has a greater impact during the winter months.
A Ridge Vent runs the length of the roof peak. Ridge Vents are available in many different styles and they can blend into the roof and often make the home more attractive. The construction of a Ridge Vent varies, but years of research has demonstrated one particular design is the most efficient. This design incorporates external baffles with an internal weather filter. This design allows air to escape, but it prevents rain and snow from entering the attic.
Working With Soffit Vents
As stated above, the Ridge Vent is only half of the ventilation solution because it needs a continuous air supply from vents in the soffit to work properly. This combination works because cooler air enters the attic from the Soffit Vents and washes the underside of the roof resulting in the Ridge Vent pulling the air from the attic.
