Manufacturer’s Sequence and Techniques

1. Measure and Cut: Measure the length and width of the area where the soffit will be installed. Cut the soffit panels to size based on these measurements.
2. Install the Furring Strips: If needed, install furring strips along the eaves to support the soffit panels. Ensure they are level and properly spaced.
3. Attach the Soffit Panels: Start from one end and place the soffit panel in the designated area. Use your hammer or nail gun to secure the panels to the furring strips, ensuring they are flush with the eaves.
4. Seal and Finish: Once all panels are installed, seal any gaps with appropriate caulk. This step will help prevent moisture infiltration.

Flashing, Edges, and Penetration Details

Proper flashing and edge treatments are vital for ensuring the longevity and effectiveness of your soffit installation.
