Improvements upon the original technology have made vinyl siding more attractive and durable; and the product’s affordability and ease of installation are tough to rival. Vinyl siding is comprised of a series of rigid polyvinyl chloride channels and trim pieces, into which the more flexible vinyl siding panels are fitted. J-channel is installed along the sloping walls where the side of the house meets the roof gables. Then the vinyl siding panels are trimmed to fit into the J-channels.

Step 1

Cut the J-channel to fit along the top of the gables beneath the rooftop. Use a hacksaw to cut the PVC J-channel to size.

Step 2

Install the J-channel along the roof gables with corrosion-resistant nails. Drive the nails through the prefabricated nail slots that run along the length of the J-channel. Leave one-thirty-second- to one-sixteenth-inch of the nail shafts exposed to allow for the natural expansion and contraction of the PVC material.

Step 3

Leave a quarter-inch between adjacent pieces of J-channel.

Step 4

Cut the vinyl siding panels to the proper length and angle. Use tin snips to cut through the siding panels. Leave a quarter-inch of space between the end of each siding panel and the back of the J-channel to allow for expansion.

Step 5

Attach the vinyl siding panels to the house frame with corrosion-resistant nails driven through the prefabricated nail slots along each panel’s top edge. Drive the nails directly through the center of each nail slot, and leave one-thirty-second- to one-sixteenth-inch of the nail shafts exposed.

Step 6

Overlap adjacent siding panels by 4 inches. Work your way up, locking the base of each siding panel course to the top edge of the panel course beneath.
