Common Roofing Terms Explained: A Florida Homeowner's Glossary

A plain-language glossary of roofing terms Florida homeowners may encounter when reviewing quotes, reading inspection reports, or talking with contractors.

Roofing has a vocabulary of its own. When a contractor mentions a "valley" or a quote lists "synthetic underlayment," homeowners who aren't familiar with the terminology can find it difficult to follow the conversation or compare proposals. This glossary collects terms a Florida homeowner is likely to encounter while researching contractors, reviewing quotes, sitting through an inspection, or reading paperwork related to a roofing project.

Entries are grouped into four categories: roof anatomy, materials, processes, and documentation and regulatory terms. Within each category, entries are listed alphabetically. Terms that are specific to Florida are marked accordingly.

Roof Anatomy

Drip Edge — A strip of metal flashing installed along the edges of a roof. Drip edge is designed to guide water off the roof and away from the underlying structure.

Eave — The lower edge of a roof that overhangs the exterior wall of the building.

Fascia — The vertical board or trim that runs along the lower edge of the roof, typically attached to the ends of the rafters. Gutters are commonly mounted to the fascia.

Flashing — Metal (and sometimes other materials) installed at roof transitions, penetrations, and junctions — such as around chimneys, vents, skylights, and where a roof meets a wall — to direct water away from those joints.

Gable — The triangular portion of a wall between the edges of intersecting roof slopes. A "gable roof" is a roof with two sloping sides that meet at a ridge, forming a gable at each end.

Hip — The external angle formed where two sloping roof sections meet. A "hip roof" is a roof style in which all sides slope downward toward the walls.

Rake — The inclined edge of a roof that runs from the eave up to the ridge on a gable roof.

Ridge — The horizontal line at the top of a roof where two opposing roof planes meet. Ridge vents and ridge caps are installed along this line.

Soffit — The underside of the roof overhang, located between the fascia and the exterior wall. Soffits are often vented to allow airflow into the attic.

Valley — The internal angle formed where two sloping roof planes meet. Water tends to channel through valleys as it runs off the roof.

Materials

Architectural Shingle — A type of asphalt shingle manufactured in a multi-layer, dimensional profile. Also referred to as laminated or dimensional shingles.

Asphalt Shingle — A shingle made from a fiberglass or organic mat saturated with asphalt and surfaced with mineral granules. Asphalt shingles are one of the more common residential roofing materials in Florida.

Clay Tile — A roofing tile made from fired clay, commonly seen in Spanish, Mediterranean, and mission-style roofs in parts of Florida.

Concrete Tile — A roofing tile made from a mixture of cement, sand, and water, molded into shapes that resemble clay tile, wood shake, or flat profiles.

Membrane Roofing — A category of roofing system, typically used on low-slope or flat roofs, in which large sheets of material are joined together to form a continuous waterproof surface. Common membrane types include TPO, PVC, EPDM, and modified bitumen.

Metal Panel — A roofing product made from sheet metal (such as steel, aluminum, or copper) formed into panels. Standing seam and exposed-fastener panels are two common configurations.

Ridge Cap — Shingles, tiles, or metal pieces installed along the ridge of a roof to cover the joint where roof planes meet.

Three-Tab Shingle — A flat, single-layer asphalt shingle with cutouts that create the appearance of three separate tabs across its face.

Underlayment — A water-resistant or waterproof material installed over the roof deck and beneath the primary roof covering (shingles, tile, metal, etc.). Underlayment can be felt-based, synthetic, or self-adhered.

Processes

Flashing Replacement — The process of removing and replacing flashing at roof transitions, penetrations, or edges. Flashing replacement may be performed as a standalone repair or as part of a larger roofing project.

Overlay — Also called a "recover" or "re-cover." A roofing approach in which new shingles are installed directly over the existing roof covering rather than removing the old materials first. Building codes place limits on how many layers a roof can have; these limits vary by jurisdiction and by the type of roof covering involved.

Recover — See Overlay. The term "recover" is used in the Florida Building Code and in many industry documents to refer to installing a new roof covering over an existing one.

Re-Roof — A general term referring to replacing the roof covering on an existing structure. A re-roof project may involve either a tear-off or a recover, depending on the scope and what codes allow.

Tear-Off — The removal of existing roof covering materials (and often the underlayment) down to the roof deck before new materials are installed.

Documentation and Regulatory Terms

Certificate of Insurance (COI) — A document issued by an insurance company that summarizes the coverage held by a contractor, typically including general liability and workers' compensation. Homeowners may request a current COI when evaluating contractors.

Final Inspection — An inspection conducted by a local building official, generally after a roofing project is complete, to confirm the work meets applicable code requirements. Final inspection procedures vary by jurisdiction.

Florida Building Code (FBC) (Florida-specific) — The statewide set of construction standards adopted by Florida that governs roofing and other building work. The Florida Building Code includes provisions for wind resistance, materials, installation methods, and other considerations that are updated periodically.

In-Progress Inspection — An inspection conducted during a roofing project, typically before new roof covering is installed, so a local building official can examine work that would otherwise be concealed (such as the roof deck, underlayment, or fastening). In-progress inspection requirements vary by jurisdiction.

License — Authorization issued by a government body permitting a contractor to perform roofing work. In Florida, roofing contractors are generally licensed through the Florida Department of Business and Professional Regulation (DBPR) as either state-certified or county-registered contractors. License requirements and scopes of work vary.

Lien Waiver — A document signed by a contractor, subcontractor, or material supplier in which they waive or release their right to place a lien on the property for payment related to work or materials already provided. Lien waivers can be conditional or unconditional, and partial or final.

Notice of Commencement (NOC) (Florida-specific) — A document filed and recorded in the county where the property is located, generally before certain construction or improvement work begins. Under Florida law, the Notice of Commencement identifies the property, the owner, the contractor, and other parties associated with the project. Rules for when an NOC is required, how it is filed, and how long it remains in effect are set by Florida statute and can vary based on project specifics.

Permit — Written authorization issued by a local building department allowing specified construction work to proceed. Permit requirements for roofing work vary by city, county, and project scope.

Product Approval Number (Florida-specific) — An identifier assigned to roofing products (and other building components) that have been evaluated under Florida's statewide product approval system or through local approval in certain jurisdictions. Product approval documentation describes the conditions under which a product is approved for use. Specific requirements vary by product category and location.

Proof of Insurance — Documentation, often in the form of a Certificate of Insurance, showing that a contractor holds specified insurance policies.

Uniform Mitigation Verification Inspection Form (OIR-B1-1802) (Florida-specific) — The standardized form used in Florida to document wind mitigation features of a home. The form is generally completed by a qualified inspector and may be submitted to a homeowner's insurance carrier. How an insurer uses the form, and any resulting premium impact, is determined by the insurer and varies by policy and location.

Wind Mitigation Inspection (Florida-specific) — An inspection that documents wind-resistant features of a home, such as roof covering type, roof deck attachment, roof-to-wall connections, and secondary water resistance. Results are typically recorded on the Uniform Mitigation Verification Inspection Form described above. The role of a wind mitigation inspection in insurance underwriting varies by insurer and policy.

Workers' Compensation Insurance — An insurance policy that generally provides coverage for medical expenses and lost wages for workers injured on the job. Florida has its own statutes governing workers' compensation requirements for contractors, and specifics vary by business size and structure.

Using This Glossary
