The Factors depend on selection of Roof Materials
- Duration and ability of roofing material to withstand
- Properties of the material such as weight, thickness, durability, slope and shape
- Whether the material eco-friendly or not / recyclable or not
- Cost of the material.
Type of Roofing Materials
- Thatch is roofing made of plant stalks in overlapping layers
- Shingle is the generic term for a roofing material that is in many overlapping sections, regardless of the nature of the material
- Ceramic tile. High cost, life of more than 100 years
- Membrane roofing. Membrane roofing is in large sheets, generally fused in some way at the joints to form a continuous surface (PVC – roofs)
- Concrete or fibre cement, usually reinforced with fibres of some sort.
- Structural concrete can also be used for flat roof constructions. There are three main categories, precast/prestressed, cast-in-place and shell.
1. Clay & Concrete Tiles
2. PVC roofing material
Polyvinyl chloride (PVC) roofing material exist as leading roofing material at present. Comparatively PVC roofing material is a better one, for its quality, durability, resistant to UV rays, availability of different colours, flexibility, a good heat stabilizer and also for its cost. A German company produced the PVC roofing material for the first time in 1966. It is a single ply, thermoplastic roofing material which popularized in a short period of time.
3. Asphalt roofing material
3.1 Asphalt shingles
3.2 Asphalt roll roofing
4. Metal Roofing (Steel, Aluminium )
Metal roofs are some of the coolest roofs around, both in temperature and style for new homes. Metal roofs are available in copper, aluminum, and stainless steel, and often have a high percentage of recycled content. They offer high insulation solar reflectance, and durability, often lasting twice as long as wood or asphalt. Metal shingles typically simulate traditional roof coverings, such as wood shakes, shingles, slate and tile. Aside from its longevity, metal shingles are much lighter than most materials and very resistance to adverse weather.
5. Eco roofing or green roofing material
