Definitions of Roofing terms as used by Built 2 Last Roofing Solutions LLC in Debary, FL. 22 terms defined.
Architectural shingles, also called dimensional or laminated shingles, are a premium asphalt shingle made of multiple layers bonded together. They create a textured, three-dimensional appearance that mimics wood shake or slate. They typically last 25 to 30 years and offer better wind resistance than traditional three-tab shingles.
Drip edge is a metal flashing installed along the eaves and rakes of a roof to direct water away from the fascia and into the gutters. Florida building code requires drip edge on most residential roofs. It also helps prevent wood rot, pest intrusion, and shingle damage at the roof's edges.
GAF Master Elite is a certification awarded to roofing contractors who meet strict standards for licensing, insurance, reputation, and ongoing training set by GAF, North America's largest shingle manufacturer. Only about three percent of roofers hold this designation, which allows them to offer enhanced warranties on GAF roofing systems.
Hurricane straps, also called clips or ties, are galvanized metal connectors that secure roof trusses or rafters to the top of exterior walls. They dramatically improve a roof's resistance to uplift during hurricane-force winds. Florida homes with properly installed straps often qualify for substantial wind mitigation insurance discounts.
Ice and water shield is a self-adhering waterproof membrane installed in vulnerable roof areas like valleys, eaves, and around penetrations. Although named for ice dams, it is also used in Florida to protect against wind-driven rain during tropical storms and hurricanes, providing an extra layer of leak protection.
Metal roofing consists of panels or shingles made from steel, aluminum, or other metals, offering exceptional longevity of 40 to 70 years. It performs well in hurricane-prone regions, reflects solar heat to lower cooling costs, and resists fire, mildew, and pests. Standing seam is the most common residential style.
A ridge vent is a continuous ventilation strip installed along the peak of a sloped roof to allow hot air and moisture to escape from the attic. Paired with soffit vents, it creates balanced airflow that reduces cooling costs, extends shingle life, and helps prevent mold and moisture damage.
A roof boot, or pipe boot, is a flexible flashing collar that seals around plumbing vent pipes protruding through the roof. Made of rubber or synthetic material, roof boots deteriorate faster than shingles under Florida's intense UV exposure. Cracked or dry-rotted boots are a leading cause of ceiling leaks.
Roof decking is the structural wood layer, usually plywood or OSB, that sits on top of the rafters and supports the underlayment and shingles. Damaged or rotted decking must be replaced during a roof installation to ensure the new roof performs as intended and remains under warranty.
Roof flashing is thin metal material installed around roof penetrations and transitions such as chimneys, vents, skylights, and walls. It seals these vulnerable joints to prevent water intrusion. Damaged or corroded flashing is one of the most common causes of roof leaks and often needs replacement during a re-roof.
A roof inspection is a professional evaluation of a roof's condition, including shingles, flashing, ventilation, decking, and interior signs of leaks. Inspections are recommended annually, after major storms, and before buying or selling a home. They help identify minor issues before they become costly repairs or insurance claim denials.
Roof pitch refers to the steepness or slope of a roof, expressed as a ratio of vertical rise over 12 inches of horizontal run. Pitch affects material choices, drainage performance, and installation costs. Low-slope roofs typically require different membranes than steep-slope roofs, which commonly use shingles or tile.
A roof replacement, or re-roof, involves tearing off all existing roofing materials down to the decking and installing an entirely new system. This differs from a roof-over, which is not permitted in most Florida jurisdictions. Full replacement allows inspection of the decking and installation of updated code-compliant components.
A roofing square is a standard unit of measurement equal to 100 square feet of roof surface area. Contractors use squares to estimate materials and labor costs. For example, a 2,000 square foot roof equals 20 squares, though the actual measurement accounts for pitch and overhangs beyond the home's footprint.
A roof valley is the internal angle formed where two roof planes meet, channeling large volumes of rainwater toward the gutters. Because valleys handle significant water flow, they are prone to leaks and require special flashing or woven shingle techniques. Proper valley construction is critical in high-rainfall regions like Central Florida.
A secondary water barrier is an added layer of waterproofing applied to the roof deck seams before the underlayment is installed. It prevents water intrusion if shingles are blown off during a storm. Florida homeowners with this feature often qualify for reduced insurance premiums under wind mitigation credits.
The soffit is the underside of the roof overhang, while the fascia is the vertical board that caps the ends of the rafters. Together they support gutters, allow attic ventilation, and protect the roof structure from weather and pests. Damaged soffit and fascia are common problems in humid Florida climates.
A storm damage claim is an insurance request filed after wind, hail, or hurricane events damage a roof. Documenting damage with photos and a professional inspection strengthens the claim. Many Florida homeowners work with licensed roofing contractors familiar with insurance processes to ensure covered repairs or replacements are properly compensated.
Three-tab shingles are a traditional flat, single-layer asphalt shingle featuring three uniform tabs that create a repeating rectangular pattern. They are the most affordable shingle option but have a shorter lifespan of 15 to 20 years and lower wind ratings than architectural shingles, making them less common in Florida today.
Tile roofing uses concrete or clay tiles known for durability, energy efficiency, and a distinctive Mediterranean or Spanish appearance popular in Florida. Tile roofs can last 50 years or more and resist fire, insects, and rot. They are heavier than shingles and require adequate structural support beneath.
Underlayment is a water-resistant or waterproof barrier installed directly on the roof deck beneath the shingles. It provides a secondary layer of protection against wind-driven rain, ice, and moisture. Common types include felt paper, synthetic underlayment, and self-adhered membranes used in vulnerable areas.
A wind mitigation inspection evaluates a home's roof and structural features to determine its ability to withstand hurricane-force winds. In Florida, this inspection can qualify homeowners for significant discounts on their windstorm insurance premiums. Features assessed include roof shape, deck attachment, secondary water resistance, and roof-to-wall connections.
