Add Eave Vents
Q: Several years ago I had vinyl siding installed on my house and under the eaves. No eave vents were installed and I’d like to do so now. Should I remove the vinyl, cut the holes, place a vent and put the vinyl back? Or, should I cut directly through the vinyl and wood to install the vent?
A: Neither. The best thing to do is buy vented eave panels that match your existing siding. The size of the attic that is being vented will determine the number of vented panels needed. For example, you need 1 square foot of soffit vent per 150 square feet of attic floor space. However, add 20-percent to this number for roofs that are 7/12 to 10/12 in pitch, and 30-percent to those that are 11/12 in pitch and steeper.
