Answer 1

Explanation:

Aluminium Sheet Roofing

Aluminium sheets are thin, lightweight, and corrosion-resistant, making them ideal for lightweight roofing systems.
They are easy to install, reduce the dead load on the structure, and are suitable for industrial sheds, temporary structures, and rural housing.
Being reflective, they help in heat insulation, although additional insulation may be needed in hot climates.

Additional Information

Slate Tile Roofing

Slate tiles are made from natural metamorphic rock and are dense and heavy, offering high durability and aesthetic value.
They are resistant to weathering and fire, commonly used in traditional or heritage structures.
Due to their weight, strong support structures are required, and they are not classified as lightweight roofing.

Flat Clay Tile Roofing

Flat clay tiles are ceramic products that are molded and fired to create durable roofing units.
They are moderately heavy, provide thermal insulation, and are commonly seen in vernacular and traditional architecture.
While they are lighter than slate, they are still heavier than metal sheets and are not considered lightweight roofing.

Madras Terrace Roofing

Madras terrace roofing is a traditional layered roofing system made using brick, lime concrete, tiles, and waterproof layers.
It is highly durable and thermally efficient but very heavy, requiring strong beams and load-bearing walls.
This is not lightweight roofing and is more suitable for permanent, load-bearing constructions.
