Learn the Language of Roofing
Not sure what your roofing contractor is talking about? You’re not alone. Roofing has its own set of terms that can feel overwhelming if you’re not familiar. At Valantine Roofing, we believe an informed homeowner makes the best decisions for their home. This glossary is designed to help you understand the most common roofing terms so you feel confident every step of the way.
Asphalt Shingles – The most common roofing material, made of fiberglass mats coated with asphalt and mineral granules. Affordable, durable, and available in a wide variety of colors and styles.
Architectural Shingles – A higher-end type of asphalt shingle with a thicker, dimensional appearance. They last longer than standard three-tab shingles and provide better wind resistance.
Blistering – Bubbles that form on shingles due to trapped moisture or poor ventilation, reducing lifespan and protection.
Dormer – A structural element projecting from the slope of a roof that often contains a window. In roofing, dormers require careful flashing to prevent leaks.
Drip Edge – Metal flashing installed along the roof edges to direct water away from the fascia and into the gutters.
Eaves – The lower edges of a roof that extend beyond the walls of the home.
Fascia – The vertical finishing edge of the roof that runs along the eaves, often where gutters are attached.
Flashing – Thin metal pieces (aluminum, steel, or copper) installed around chimneys, skylights, vents, and valleys to prevent water from seeping into the roof structure.
Granules – The ceramic-coated particles embedded on the surface of asphalt shingles. They provide UV protection, fire resistance, and color.
Ice & Water Shield – A specialized underlayment installed in vulnerable areas like valleys, roof edges, and around penetrations to guard against leaks caused by ice dams and heavy rain.
Luxury Shingles – Premium asphalt shingles designed to mimic natural materials like slate or wood shake. Offer the highest curb appeal but also the highest cost.
Pipe Boot – A specially designed piece of flashing that seals around plumbing vent pipes where they protrude through the roof.
Ridge Vent – A type of roof vent installed at the peak (ridge) of the roof that allows hot, humid air to escape from the attic.
Roof Decking (Sheathing) – The wooden boards (usually plywood or OSB) attached to the roof trusses that provide the structural base for all roofing materials. If it’s rotted or weak, it must be replaced before new shingles go on.
Soffit – The underside of the eaves. Proper soffit ventilation helps regulate attic airflow.
Soffit Vent – Vents installed under the eaves of the roof that allow cool, fresh air to enter the attic. Work with ridge vents to create proper airflow.
Square – A roofing industry measurement equal to 100 square feet of roofing material. Example: A 2,000-square-foot roof equals 20 squares.
Underlayment – A water-resistant or waterproof barrier installed between the roof decking and the shingles. Adds extra protection against leaks.
Valley – The area where two roof slopes meet, forming a channel that directs rainwater and snow down into the gutters.
