Roof-Type Taxonomy

A practical guide to roof shapes, slopes, and roofing systems used in South Florida.

Roof-Type Taxonomy

Roof type is best understood in three layers: roof geometry (shape), roof slope, and roof covering/system (the materials and assembly that provide weather protection). These categories can overlap. A hip roof, for example, can use asphalt shingles, tile, or metal; a low-slope roof may use TPO, PVC, EPDM, modified bitumen, or another approved membrane system.

01 · GEOMETRY

Roof Shape

The roof's physical form—such as gable, hip, shed, or more complex combinations.

02 · ROOF SHAPE

Gable Roof

Two primary sloping roof planes meet at a ridge, leaving triangular end walls.

03 · ROOF SHAPE

Hip Roof

Roof planes slope upward from multiple exterior walls toward a ridge or ridges.

04 · SLOPE

Low-Slope Roof

A roof with a relatively shallow incline, typically designed around positive drainage and weatherproofing.

05 · SLOPE

Steep-Slope Roof

A roof system using a steeper incline and water-shedding roof coverings.

06 · COVERING

Asphalt Shingle

A widely used steep-slope roof covering made from asphalt-based shingles reinforced with a mat and surfaced with mineral granules.

07 · COVERING

Tile Roofing

Clay or concrete tiles form a durable steep-slope roof covering when installed as part of an approved roof assembly.

08 · COVERING

Metal Roofing

Metal roof systems use formed metal panels or metal shingles with system-specific seams, fasteners, clips, flashings, and underlayments.

09 · LOW-SLOPE SYSTEM

Single-Ply Membrane

Factory-manufactured membrane sheets installed as a weatherproofing layer over a low-slope roof assembly.

10 · LOW-SLOPE SYSTEM

Modified Bitumen

A reinforced asphalt-based membrane system commonly used on low-slope commercial and multifamily roofs.

11 · LOW-SLOPE SYSTEM

Built-Up Roofing (BUR)

A multi-layer low-slope roof membrane traditionally constructed from alternating layers of bitumen and reinforcing felts, with a surfacing layer.

12 · SPECIALTY

Other Roofing Systems

Specialty systems can include slate, wood shakes, liquid-applied membranes, spray polyurethane foam, and other approved assemblies.

This guide is general educational information, not a design specification, engineering opinion, code determination, warranty, or substitute for project-specific plans, manufacturer instructions, permitting requirements, or applicable building codes. Final roof-system selection depends on the building, roof geometry and slope, structural conditions, exposure, wind requirements, drainage, materials, manufacturer requirements, and applicable jurisdictional requirements.

How we work

You'll always know what's next.

The same documented process runs every Golden Keys Roofing project — roofing or new construction, single-family or 84-unit condo.

01
Inspection & discovery
On-site walk, drone imagery, written findings, and a plain-language conversation about what we saw and why it matters.
02
Options briefing
Repair vs. replace or scope options with directional pricing ranges — no pressure, no upsell theatre.
03
Documented proposal
A written scope, materials list, timeline, and warranty coverage in plain language you can share with a spouse, board, or lender.
04
Organized execution
A named project lead, daily updates, tidy site standards, and photos of the work as it happens.
05
Closeout & warranty
Final walkthrough, punch list resolution, wind-mit or warranty certificates, and registration of every warrantable component.
