Algae Resistant Shingles
Shingles manufactured with copper granules that inhibit the growth of blue-green algae, which causes dark streaks on roofs. Common in humid climates but beneficial in Colorado where moisture can collect in shaded areas.
Aluminum Siding
Lightweight metal siding popular from the 1940s-1970s. Durable and low-maintenance but dents easily and can oxidize over time. Still found on many Colorado homes.
Architectural Shingles
Multi-layered asphalt shingles that create a dimensional, textured appearance. Also called laminated or dimensional shingles. They're thicker, more durable, and more wind-resistant than 3-tab shingles.
Argon Gas
An odorless, colorless gas used to fill the space between panes in insulated glass units. Argon is denser than air and reduces heat transfer, improving the window's insulating ability by 30-40%.
Asphalt Shingles
The most common residential roofing material in North America. Made of a fiberglass mat coated with asphalt and surfaced with mineral granules. Available in 3-tab and architectural styles.
Attic Ventilation
The system of intake and exhaust vents that circulates air through the attic space. Proper ventilation prevents moisture buildup, ice dams, and premature shingle deterioration.
Awning Window
A window hinged at the top that opens outward from the bottom. Provides ventilation even during light rain because the open sash acts as an awning.
Back-Primed
Siding that has been primed (sealed) on the back side before installation. Back-priming prevents moisture absorption from behind, extending the life of the siding — especially important for wood and fiber cement.
