How to Install Vinyl Siding on Eaves & Overhangs

Install J-channels on both sides of the overhang. Nail the channel along the edge of the house on the wall just underneath the eave or overhang, so that the hook part of the J is facing outward, away from the house. On the opposite side of the overhang, nail the vertical section of the J-channel along the edge of the roof, so that the hook section of the J hangs down under the edge of the overhang.

Measure the distance between the two vertical sections of J-channels with a tape measure, and subtract a quarter inch from this measurement. Mark a piece of vinyl paneling, using a tape measure and pencil, and cut it with a utility knife. Slide it into place so that it locks into the hooked sections of the J-channeling.

Continue cutting pieces to fit using the same measurement, or adjust if necessary, if you are dealing with out-of-square building. Attach the vinyl sections to each other with the tongue-and-groove system for the eave pieces and slide each piece into place so that it locks within the J-channeling on either side of the overhang, holding the pieces in place.
