Is vinyl siding waterproof?
Despite common misconceptions, vinyl siding is not waterproof. Thanks to its overlapping profile, a standard interlocking wall of horizontal vinyl panels will effectively shed most rain and water away, providing superior water resistance. However, no vinyl siding is completely impervious to outside moisture from dampness rain or snow. For that reason, siding panels are manufactured with “weep holes” located at the bottom of each panel projection edge. These small but important outlets help channel away water that might find its way inside the siding wall through the panel seams and around moldings, windows, door and fixtures. Weep holes also allow the infiltration of air, which also helps to dry out the inner surface of the siding while promoting evaporation of any remaining moisture. The application of house wrap and or insulation board also provides for a secondary defense against outside moisture that might penetrate the siding and come in contact with the original sheathing.
