Roofing Materials Glossary

Understanding the materials used on your roof is key to interpreting inspection reports, comparing repair estimates, and knowing how your home is protected from Jacksonville’s heat, rain, and high winds. This glossary provides clear explanations of the roofing materials commonly used across Florida, helping homeowners make confident, informed decisions.

This glossary is designed as a quick reference for homeowners reviewing roofing estimates, inspection reports, or material options. Each entry provides a clear explanation of the material, its purpose, and where you may encounter it on Florida roofs. This glossary partners with our Roofing Terms Glossary and Roof Type Glossary so you can explore how roof components, materials, and designs all work together. Browse the alphabetical list below to strengthen your understanding of the products that protect your home.

A basic asphalt shingle with three evenly spaced tabs per strip (about 12″ each). Typically rated for 20–25 years. More affordable but thinner and less durable than architectural shingles.

A

Also called laminated or dimensional shingles. Built with heavier fiberglass mats and asphalt for improved strength, wind resistance, and a thicker, layered appearance. Commonly rated for 30+ years.

North America’s most widely used roofing material. Made from asphalt-saturated mats with mineral granules for protection. Available in 3-Tab, Architectural and designer styles. When installed per Florida Building Code fastening and wind-uplift requirements, both are acceptable for residential roofing. Learn more about asphalt shingles in our product page.

If you’re comparing colors, you can also use the GAF Design Center to preview options before choosing a shingle style.

B

A multi-layer system also known as tar and gravel. Alternating layers of bitumen and reinforcing felt are applied, then topped with gravel or a mineral cap sheet. Provides excellent waterproofing and UV protection on low-slope and flat roofs.

E

A durable black synthetic rubber membrane commonly used on commercial and low-slope roofs. Flexible, long-lasting, and resistant to heat, hail, and temperature extremes. Installed in large sheets with minimal seams.

M

Panels made from steel, aluminum, galvalume, zinc, copper, or metal alloys. Known for excellent wind resistance, longevity, and performance in coastal and high-wind regions of Florida. Learn more about metal roofing in our product page.

• Standing Seam Metal Panels – Concealed-fastener system with raised seams. Provides superior wind uplift resistance and reduced leak exposure.
• PBR Panels (Purlin Bearing Rib) – Exposed-fastener panel with deep ribs for structural strength. Common on metal buildings.
• 5V Crimp Panels – Traditional Florida metal profile with rib shapes optimized for water shedding and wind resistance.
• Common Metal Types: Steel, Aluminum, Galvalume, Zinc, Copper, Alloys

A polymer-enhanced asphalt membrane designed for flexibility and durability. Installed via torch-down, hot asphalt, cold adhesive, or self-adhered sheets. Often paired with insulation boards to add slope and improve energy efficiency on flat roofs. Learn more about modified bitumen in our product page.

P

A white, flexible single-ply membrane resistant to chemicals, grease, and animal fats. Ideal for restaurants and commercial buildings. Its high reflectivity improves energy efficiency in Florida’s hot climate.

R

Economical exposed-fastener panels with visible screw lines. Durable for residential and light commercial projects and a cost-effective alternative to standing seam systems.

Fluid-applied products that form a seamless, waterproof surface. Used to extend roof life and add UV protection. Not intended for areas with routine foot traffic.

S

Flexible membranes used on flat and low-slope roofs. Installed in large sheets with minimal seams. Types include TPO, EPDM, and PVC. Systems may be ballasted, mechanically attached, or fully adhered depending on project design and wind requirements.

T

Made from clay, concrete, ceramic, or slate tiles installed in overlapping rows. Highly durable, fire-resistant, and energy-efficient. Performs well in Florida’s heat and offers one of the longest service lives of any roofing material. Learn more about tile roofing in our product page.

A heat-weldable white membrane widely used on commercial and flat roofs. Known for strong seam durability, UV protection, and cooling efficiency.
