If you’re planning new siding for your home or business, you’ll quickly notice that contractors use a lot of industry-specific terms. Knowing this vocabulary doesn’t just make you sound more informed—it helps you communicate your needs clearly, compare materials effectively, and make confident decisions that protect both your budget and your property.
Below, we’ve broken down some of the most common siding terms you’ll hear during the process, so you’ll feel equipped every step of the way.
Choosing siding isn’t only about curb appeal—it’s about protecting your property from the elements while keeping energy costs in check.
Whether you’re replacing outdated siding or starting fresh with new construction, a little knowledge goes a long way in making sure your investment lasts.
Thickness or gauge
Refers to the siding’s measurement in millimeters. Thicker siding generally offers better durability and impact resistance.
Wind load rating
Indicates how much wind pressure the siding can withstand, which is especially important in areas prone to storms or high winds.
Soffit
The material covering the underside of your roof’s overhang. Ventilated soffits improve airflow and reduce moisture issues in your attic.
Course
A single horizontal row of siding panels.
Dutchlap or Shiplap
Popular panel styles. Dutchlap has a beveled edge for shadowing; shiplap overlaps for a smooth, tight finish.
Fascia Board
The long, straight board running along the edge of your roof where gutters are often mounted.
Water Table Band
A decorative trim piece used at the base of exterior walls to create a visual break.
Flashing
Thin, weather-resistant metal installed at siding joints, around windows, and doors to prevent water infiltration.
Weep Hole
Small openings that allow water or condensation to drain out from behind siding panels.
Square
Unit of measure for siding equal to 100 square feet (or a 10-foot by 10-foot wall section).
Furring/Furring Strip
Strips of wood or metal used to level a surface before siding installation.
Lap
The part of the roofing/siding material that overlaps a section of adjacent material.
Drip Cap
A piece set on top of the door casing and fastened. The drip cap has a groove cut underneath in the bottom front edge. This groove causes water to drip off the front edge rather rolling back to the door or window casing.
