Soffit Installation | VSI

Soffit is used to enclose the underside of an eave. The installation of soffit will determine the positioning of the inside and outside corner posts. It also is necessary to complete the soffit before the final course of siding is installed on the wall.

Vinyl soffit is designed to be easily installed lengthwise from wall to fascia. Soffit panels are similar to vertical siding. Manufacturers produce both solid and vented panels, as well as combinations of the two.

NOTE: Ventilation Requirements: Proper attic ventilation is important for any home. Consult local building codes for the appropriate requirements for a specific geographic area, and use vented soffit or other vented products as required.

Inspect and plan the job in advance. For re-siding applications, nail down any loose panels, boards, or shingles. Check surfaces for straightness and fur when necessary. Surfaces should be uniform and straight from various viewing angles.

The procedure used to install soffit depends on the construction of the eave. There are two different types of eaves:

When transitioning soffit at the peak of a gable (Fig. 63), secure two J-channels back to back to receive an individual piece of soffit on each accessory. Alternatively, bend a section of soffit, using a field brake, to match the angle of the peak of the gable.
