Whether you need roof replacement or new siding, you must do your research. With more information in hand, you can make more informed decisions on your project. It will also help you better understand your contractor.

Here are siding terms every homeowner should know.

Backerboard

Contractors place backerboard between the studs and the siding so they can install your new siding evenly.

Channel

The part of a siding panel where installers insert trim or another piece of siding is called the channel.

Drip Cap

Also referred to as head flashing, the drip cap diverts water away from the upper areas of vertical siding.

Face

It pertains to the side of the siding that is visible following installation.

Fascia

You’ll find the fascia board underneath the roof line. Fascia conceals the ends of roof rafters.

Flange

Typically at the top of a siding panel, the flange contains the mounting holes.

Flashing

When you speak to siding or roof replacement companies, they might mention a component called flashing. It is a piece of metal installed under or beneath windows, corner posts, J-channels and other areas that water can infiltrate.

Furring

Experts use furring strips to create a flat surface for siding installation.

J-Channels

Siding trim or J-channels give the edges of your siding a finished look.

Lap

The end of two siding panels is called a lap. Contractors overlap panels to hide nails and to give the material room for expansion and contraction.

Nail Hole Punches

These are the holes in the flange where nails go through and secure panels to exterior walls.

Square

A 10 feet × 10 feet piece of siding is often called a square.

Starter Strips

Starter strips serve as the base for the first row of siding.

Weep Holes

You’ll see weep holes in the lower edge of your siding. These small holes prevent condensation from accumulating between your siding and the backerboard.
