Construction Technology

These may be either flat or pitched (Figure 4.32).Pitched roof – any roof having a sloping surface in excess of 10 degrees pitch. Those with a single sloping surface are known as mono pitch and those with two opposing sloping surfaces are known as double pitched.Gable roof – a double pitched roof with one or more gable end.Hipped roof – a double pitched roof where the slope is returned around the shorter sides of the building to form a sloping triangular end.Flat roof – any roof having a pitch or slope of up to 10 degrees to the horizontal.Lean-to roof – a single pitched roof, which butts up to an existing building.
Roofings

BS 5534: Code of practice for slating and tiling Part 1: 1990 Design and Part 2: 1986 Design charts for fixing roof slating and tiling against wind uplift and BS 8000 Workmanship on building sites Part 6: Code of practice for slating and tiling of roofs and claddings deal with design factors and installation methods for pitched roofs using dry jointed lapped units as a covering. The construction methods adopted for pitched roofs have, in the past, given less cause for concern than those for flat roofs because they shed water more rapidly and most types rely on a multi-defence system against the penetration of moisture. In recent years, however, pitched roofs have themselves been a source of concern because of the incidence of wind damage and problems of condensation within the structure. Other British Standards are also available for specific materials used as roof finishes, and these will be referred to at appropriate points in this chapter.
Rolled Zinc
Published in Frank Porter, Zinc Handbook, 1991
The anticipated maintenance-free life of a properly laid zinc-copper-titanium alloy pitched roof, with a metal thickness of 0.8Â mm is about 60−80 years under average urban conditions in Northern Europe but longer in areas of the world with less sulphur pollution. Some factors affecting corrosion resistance are mentioned above and general aspects are fully covered in Chapter 5. Sheet and strip should be kept dry in transit and stored dry and under cover and off the ground to avoid unsightly storage stains, which are not easily removed and do not completely disappear in service.

The BIPV systems are used in high-rise commercial buildings that serve both power generations and aesthetical appearance. In general the building roofs may either be flat, curved or sloped. In all the types of roofs, any BIPV systems such as opaque, transparent or semi-transparent may be used based on requirement of the occupants. In the case of pitched roof applications, it may be in the form of tiles, shingles, metal, opaque, and transparent roof. The facades include walls, windows, and other elements such as lintels and sunshades. The other applications of BIPV include urban structures, such as very tall commercial buildings, super markets, and architectural fabrics. The classifications of BIPV integration is presented in Figure 1.
