A–C
- Asphalt Shingles
- A common roofing material made of fiberglass or organic mat coated with asphalt and topped with granules for protection.
- Blistering
- Bubbles that form on shingles due to trapped moisture or poor ventilation, which can reduce shingle lifespan.
D–F
- Decking
- The wooden base of a roof (often plywood or OSB) to which shingles and underlayment are attached.
- Drip Edge
- Metal flashing installed along roof edges to direct water into gutters and prevent damage to the fascia.
- Fascia
- The horizontal board at the edge of the roof where gutters are attached. Protects the roof and interior from moisture.
G–L
- Gutters
- Drainage channels that direct rainwater off the roof and away from the home’s foundation.
- Granules
- Mineral-coated materials embedded on shingles to provide UV protection, color, and fire resistance.
- Hand Nailing
- The process of installing roofing nails manually rather than with a nail gun, often seen as a higher-precision method.
- Ice & Water Shield
- A waterproof underlayment installed along eaves, valleys, and roof penetrations to prevent leaks from ice dams or wind-driven rain.
- Impact Resistance
- A roof’s ability to withstand hail or falling debris. Materials are rated Class 1–4, with Class 4 offering the most protection.
- Laminated Shingles
- Also called architectural shingles; thicker asphalt shingles with a dimensional appearance and better durability than 3-tab.
M–R
- Metal Roofing
- A long-lasting, energy-efficient roofing material available in panels or shingles. Ideal for durability and fire resistance.
- OSB (Oriented Strand Board)
- Engineered wood panels used for roof decking, made from compressed wood strands and adhesives.
- Pitched Roof
- A roof with a slope to facilitate water runoff, as opposed to a flat roof.
- Pipe Boot
- A type of flashing that seals around plumbing vent pipes to prevent water intrusion.
- Rafters
- Inclined wooden beams that support the roof structure and create its shape.
- Rake Edge
- The inclined edge of a gable roof. Rake flashing helps prevent water infiltration from wind-driven rain.
- Roof Repair
- Fixing isolated roof issues such as missing shingles or small leaks without replacing the whole roof.
- Roof Replacement
- Stripping the old roofing system and installing an entirely new one, including underlayment, flashing, and shingles.
- Roof Inspection
- A comprehensive evaluation of the roof’s condition to identify wear, damage, and needed repairs.
S–Z
- Roof Financing
- Flexible payment plans offered to homeowners for roof repairs or replacement without upfront cost.
- Standing Seam Metal Roof
- A sleek metal roofing system with raised vertical seams that interlock, ideal for durability and modern aesthetics.
- Soffit
- The underside of the roof overhang, typically vented to allow airflow into the attic.
- Solar Roofing
- A roof system that incorporates photovoltaic panels or shingles to generate electricity while protecting the home.
- Starter Shingles
- Special shingles placed along eaves and rakes as the first line of defense against wind uplift.
- Synthetic Underlayment
- A durable, water-resistant material used beneath shingles for better protection than traditional felt paper.
- Tab
- The exposed portion of a 3-tab asphalt shingle that gives the roof its look.
- Underlayment
- A protective layer between the shingles and the roof deck, preventing moisture infiltration.
- Valley
- The internal angle where two roof slopes meet. Special flashing or materials are used here to prevent leaks.
- Ventilation
- The process of exchanging air in the attic to prevent heat and moisture buildup, improving energy efficiency and roof longevity.
- Warranty
- A manufacturer’s or contractor’s guarantee for roofing materials and/or workmanship over a defined period.
- Wind Damage
- Roof damage caused by strong winds, including lifted shingles, missing pieces, or exposed underlayment.
