Contractor Handbook - Installing Soffit System

General Soffit System Installation

  • Miter soffit at corners rather than butting soffit at corners. Use a “T” mould at joints rather than sealants or adhesives.
  • Make sure the soffit panel is fully engaged into the plowed slot on the fascia and frieze board.
  • Vents can be screened if required by code.
  • Building the soffit system on the ground and installing it as one piece in not recommended. The soffit overhang is not going to be a perfect 90° angle. Install the three components individually so they properly conform to the building structure.
  • VERSATEX’s Notched Fascia extends 1/2” below the soffit, forming a natural drip edge.
  • At all Notched Fascia and Frieze/Rake board joints, use a shiplap joint. A shiplap is not only stronger, but also hides unsightly gaps in the trim.
  • Before installing make sure rafter tail ends are aligned and in the same plane.
  • If using beadboard for soffit, use 1” nominal beadboard products or thicker boards for spans of 16” to 24”. Never span VERSATEX more than 24”.
  • If using 1/2” beadboard for soffit, orient it perpendicular to the joists.

Eave Application

  • Step 1: Fit your VERSATEX Soffit panel to the overhang, making sure the outside edge of the soffit projects 7/16" beyond the subfascia. Position the slotted vents toward the outside of the eave for optimal air flow.
  • Step 2: Secure the soffit to the underside of the subfascia and to the framing member along the other edge of the soffit panel at the frieze. Fasteners should be 4d or 5d stainless steel nails or trim screws spaced 12" on center at all panel edges and at all intermediate supports. Reduce spacing to 6" on center if soffit is not supported by fascia and frieze.
  • Board Width Fasteners per width a max of everny 16" on center
    12" 3-4
    16" 4-5
  • Step 3: VERSATEX recommends the use of a “T” mould at the butt joints between two soffit panels and at all mitered soffit corners.
  • Step 4: Use a Standard Stealth Trimboard for the frieze board, making sure the long flat edge of the trim butts tight against the soffit panel with the siding pocket on the Stealth Trim at the bottom and against the exterior wall to accept siding.
  • Step 5: Fasten the Frieze board to the wall studs with 8d stainless steel nails with annular threads and blunt points or trim screws
    spaced a maximum of 16" on center.
  • Step 6: Install the VERSATEX Notched Fascia board on top of the subfascia aligning the pocket with the projecting edge of the VERSATEX Vented Soffit panel before fastening it to the face of the subfascia. To reduce linear movement in the fascia board, glue it to the subfascia with a construction adhesive like Liquid Nails Sub-Floor or Heavy Duty Construction Adhesive.
  • Step 7: The top edge of the fascia can be flashed with a piece of undersill trim or hidden behind a drip edge or other roof edge flashing. Be sure the edge angle on the soffit panel is cut to the same slope as the roof where two soffit panels abut.
