Roofs can be classified in various ways, including:

1. By shape: Roofs can be classified based on their shape, such as gable, hip, flat, shed, gambrel, mansard, and butterfly roofs.

2. By material: Roofs can be classified based on the materials used, such as asphalt shingles, metal, tile, wood shakes, and slate.

3. By slope: Roofs can be classified based on their slope or pitch, such as low-slope, medium-slope, and steep-slope roofs.

4. By construction method: Roofs can be classified based on their construction method, such as built-up roofs, single-ply roofs, and green roofs.

5. By function: Roofs can be classified based on their function, such as residential roofs, commercial roofs, industrial roofs, and institutional roofs.

6. By design: Roofs can be classified based on their design, such as flat roofs, pitched roofs, and curved roofs.

7. By location: Roofs can be classified based on their location on a building, such as main roofs, dormer roofs, and porch roofs.

Structural Design:

- Flat roofs: Sloped at less than 10 degrees
- Pitched roofs: Sloped at more than 10 degrees
- Curved roofs: With a curvilinear shape
- Suspended roofs: Supported by cables or tensors

Materials:

- Asphalt shingles: Durable and cost-effective
- Metal roofing: Lightweight, reflective, and fire-resistant
- Tile roofing: Aesthetically pleasing, long-lasting, and fire-resistant
- Green roofs: Covered with vegetation to provide insulation, air purification, and stormwater retention

Form and Style:

- Hipped roofs: Sloped on all sides to a central ridge
- Gabled roofs: Sloped on two sides to form a gable
- Mansard roofs: Double-sloped roofs with a steep lower slope and a flatter upper slope
- Gambrel roofs: Double-sloped roofs with a steep lower slope and a gentle upper slope
- Dormer roofs: Protruding structures installed on pitched roofs to provide natural light and ventilation

Functions:

- Protective roofs: Primary function is to protect the interior of the building from the elements
- Thermal roofs: Designed to provide insulation and control heat gain and loss
- Clerestory roofs: Incorporated to enhance natural lighting
- Architectural roofs: Emphasize aesthetic and ornamental aspects in addition to functionality

Other Classifications:

- Single-ply roofs: Made of a single layer of membrane
- Built-up roofs: Consisting of multiple layers of membrane
- Modified bitumen roofs: Hybrid systems that combine asphalt with polymers or SBS
- Spray foam roofs: Applied in liquid form and expand to create a seamless insulation and waterproofing layer
- Inverted roofs: With the insulation layer placed above the waterproofing membrane
