The “face” of your siding is the visible portion once the siding is installed. In other words, it’s the part people will actually see when the siding installation is complete.

Fascia Board

You might remember fascia from our roofing terms guide. The meaning is the same here: a straight piece of board that runs along the lower edge of your roof. Fascia plays a big role in the security and longevity of your siding.


Flashing is a construct or strip made of aluminum or another common durable metal used to prevent moisture intrusion along windows, doors, other home protrusions, and sometimes on the border of siding.


Lapping refers to the overlap of siding or trim materials. This is done to accommodate for the natural expansion of materials due to temperature changes and wind. You’ll see lap used in many of the modern siding types and jobs, including vinyl and wood siding.


The miter, or miter joint, is where two edges of siding panel meet. Most commonly, a miter is situated at a 90 degree angle.


When siding fasteners are trimmed off to make sure your home lugs are used to fasten the siding snugly without needing nail slots—ensuring the correct siding size without excessive overlap or excess material hang.


Battens are used in wood siding and are the component used to seal any joints that do not require a more specialized joint meet.

Nailing Hem

Siding can’t just be nailed anywhere in order to fasten it to the side of your home. Nails or staples have to be situated in nail slots or fastening holes, which are contained in the nailing hem.

Weep Holes

Weep holes are found at the bottom edge of siding. These are here to prevent moisture accumulation and water intrusion, giving moisture a natural place to bleed out.

Starter Strip

The starter strip is essentially what it sounds like. This is the first round of material used as a base for fastening the first course of siding during a new installation.
