Throughout your siding project, you’ll likely hear various siding terms from your contractor. Make sure your siding vocabulary is up to speed so that you’ll have a clearer idea of what you can expect. Top-rated siding and roofing contractor All American Roofing lists some basic terms that are worth remembering.


Typically a flat material used on the face of your home, the backerboard is applied between the studs and siding. Its main purpose is to ensure an even surface for the installation.


Often used in “board and batten” siding, a batten is a strip of wood used for sealing joints.


A course is basically one row of siding that runs the length of the exterior wall.

Drip Cap or Head Flashing

A drip cap is a piece of trim that’s designed to keep water away from the top of the vertical siding.


F-channel is a molding shaped like the letter “F”. It is used to trim siding installed at a 90-degree angle.


Fascia is a horizontal board that covers the joint between the top of an exterior wall and the roof’s overhanging lower edge.


Flashing is also a roofing term. But in siding, it refers to a piece of metal placed above windows and doors. Its main function is to prevent water from entering your home.

Lap or Overlap

An overlap is designed to conceal nails that attach the siding to your home’s exterior.

Siding Square

A siding square is a piece of siding that measures 10 feet by 10 feet.

Starter Strip

A starter strip secures the first panel or course of siding to a wall.

Strapping or Furring Strips

Strapping is a piece of metal or wood found on the exterior wall. This is where the siding is supposed to attach.

Weep Holes

Weep holes are small holes located at the bottom edge of the siding. They keep water from collecting between the siding and the backerboard.
