Term	Definition
Roofing
Asphalt Shingles	Asphalt shingles are one of the most popular roofing materials due to their durability and cost-effectiveness. They are made of a fiberglass mat coated with asphalt and mineral granules, which provide protection against the elements and give the shingles their color and texture.
Underlayment	The underlayment is a protective layer installed between the roof deck and the shingles. It’s typically made of felt or synthetic materials and acts as an extra barrier against moisture, ensuring that your roof remains watertight even if the shingles are damaged.
Flashing	Flashing refers to the thin pieces of metal installed at various points on a roof to prevent water from seeping into the structure. Commonly used around chimneys, vents, and skylights, flashing is crucial for maintaining the integrity of your roof.
Ridge Vent	A ridge vent is an essential component of a well-ventilated roof. Installed along the ridge line, it allows warm, moist air to escape from the attic, which helps to prevent mold growth and extend the lifespan of your roofing materials.
Soffit	The soffit is the material that covers the underside of the roof’s overhang. It plays a key role in ventilating the attic and preventing moisture buildup, which can lead to rot and other issues. Soffits are often perforated to allow airflow.
Fascia	Fascia is the board that runs along the edge of the roof, just under the shingles. It provides structural support for the gutter system and helps protect the roof’s edge from water damage. Fascia boards can be made from wood, vinyl, or aluminum.
Ice Dam	An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow from draining off. This can lead to water backing up under the shingles and into the home. Proper insulation and ventilation are key to preventing ice dams.
Gable	A gable is the triangular portion of a wall between the edges of a sloping roof. Gables can add architectural interest to a home and are a common feature in many roof designs.
Roof Pitch	Roof pitch refers to the steepness of a roof, usually expressed as a ratio of the vertical rise to the horizontal run. Understanding your roof’s pitch is important for selecting appropriate roofing materials and ensuring proper drainage.
Siding
Vinyl Siding	Vinyl siding is a popular choice for homeowners due to its durability, low maintenance, and cost-effectiveness. Made from polyvinyl chloride (PVC), it comes in a variety of colors and styles, mimicking the look of wood without the need for painting or staining.
Fiber Cement Siding	Fiber cement siding is made from a mix of cement, sand, and cellulose fibers. It’s known for its strength and resistance to fire, termites, and rot. This type of siding can be painted and is available in various textures, including wood grain and smooth finishes.
Lap Siding	Lap siding, also known as clapboard or bevel siding, features long, horizontal boards that overlap each other. This design helps to shed water and protect the home from the elements. It’s a classic look often associated with traditional and colonial-style homes.
Board and Batten	Board and batten is a siding style that consists of wide vertical boards with narrower strips, called battens, covering the seams. This design provides a distinctive, rustic appearance and is commonly used in farmhouse and cottage-style architecture.
Cladding	Cladding refers to the exterior finish materials that are applied to the structure of a building. It serves both aesthetic and functional purposes, protecting the building from weather and providing insulation. Common materials include wood, vinyl, fiber cement, and metal.
House Wrap	House wrap is a synthetic material used to protect buildings from moisture and air infiltration. Installed underneath the siding, it acts as a weather-resistant barrier while allowing moisture vapor to escape, preventing mold and rot inside the walls.
Trim	Trim is the material used to finish the edges and corners of siding installations. It provides a polished look and helps seal the joints and seams, preventing water infiltration. Trim can be made from various materials, including wood, vinyl, and composite materials.
Window
Double-Hung Windows	Double-hung windows feature two sashes that move up and down independently. This design allows for excellent ventilation and easy cleaning, as both the top and bottom sashes can be tilted inward.
Casement Windows	Casement windows are hinged at the side and open outward like a door, operated by a crank. They provide excellent ventilation and unobstructed views, making them a popular choice for many homeowners.
Bay Windows	Bay windows project outward from the exterior wall, creating a small shelf or ledge inside. Typically composed of a central fixed window flanked by two operable windows, they add extra space, light, and a touch of elegance to any room.
Glazing	Glazing refers to the glass panes in a window. Single glazing has one layer of glass, while double glazing consists of two layers with a sealed air space in between for better insulation. Triple glazing is also available for enhanced energy efficiency.
Low-E Glass	Low-E (low-emissivity) glass has a special coating that reflects heat while allowing light to pass through. This helps keep your home warmer in the winter and cooler in the summer, improving energy efficiency and comfort.
Window Sash	The sash is the part of the window that holds the glass and the framework around the glass. In operable windows, the sash moves to allow for ventilation. Properly maintained sashes ensure smooth operation and energy efficiency.
Muntins	Muntins are the strips that divide the glass panes in a window. They can be part of the window’s structure or simply decorative. Muntins add a traditional, divided-light appearance to windows.
Storm Windows	Storm windows are installed on the outside or inside of existing windows to provide extra insulation and protection from the elements. They are a cost-effective way to improve energy efficiency and reduce drafts in older homes.
Gutter
Downspout	A downspout is a vertical pipe attached to the gutter system that carries rainwater from the roof to the ground or drainage system. Properly functioning downspouts are essential for preventing water damage to your home’s foundation.
Gutter Guard	Gutter guards are protective covers installed over gutters to keep debris like leaves and twigs out while allowing rainwater to flow through. They help reduce maintenance and prevent clogs that can cause water overflow and damage.
K-Style Gutters	K-Style gutters are the most common type of gutter in residential use. They have a flat back and a decorative front that resembles crown molding, which makes them both functional and aesthetically pleasing. They come in various sizes to accommodate different roof sizes and rainfall amounts.
Fascia Mount	A fascia mount refers to gutters that are attached directly to the fascia board, which is the horizontal board running along the edge of the roof. This mounting method ensures stability and proper alignment of the gutter system.
Seamless Gutters	Seamless gutters are custom-made from a single piece of material, typically aluminum, to fit the exact dimensions of your home. This design minimizes the risk of leaks and requires less maintenance compared to traditional sectional gutters.
Splash Block	A splash block is a device placed at the end of a downspout to direct water away from the foundation of a house. It helps prevent erosion and water damage by dispersing the water over a larger area.
Gutter Pitch	Gutter pitch refers to the slight angle at which gutters are installed to ensure that water flows toward the downspouts. Proper gutter pitch is crucial for preventing standing water and ensuring efficient drainage.
