Soffit Vent Attic Insulation

Their low profile and shingle cover make them blend into the roof and they distribute ventilation evenly along the ridge.

Soffit vent attic insulation.

Ridge vents are available from roofing dealers and many home centers. Clear loose fill insulation from inside the attic by pulling it off the vent covers and making piles on the attic side of the vents. Soffit vents may leave air trapped at the top of your attic. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

If there s blown in insulation like ours rake back the fluffy stuff with a 3 or 4 ft long 1 x 6 or use a garden rake or hoe. Covering up the soffit vents with loose fill or batts which can happen if you stuff insulation along the eaves is a huge no no. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. You re also less likely to damage the shingles when you install them.

If the attic is insulated with fiberglass batts just pull back any that are blocking the flow of air. Ridge vents with attic vent baffles have several advantages. Intake vents located at the lowest part of the roof under the eaves allow cool. The soffit vents are now installed but you still need to make sure there s no insulation blocking the new vents.

Gable vents may circulate air through only a small percentage of your attic. Unfortunately blow in insulation can drift into. For the same reason insulation shouldn t touch the roof s underside. There should be no insulation within 3 inches of the vent.

Static roof line vents are effective for ventilation but generally aren t recommended due to issues with leaks.
