Why Copper Sheets used for Roofing Purpose

1. Top 4 Reasons Why Copper Sheets are Extensively used for Roofing Purpose Copper roofing has been used in buildings since la long time because it has the natural potential to form a protective green layer and enhance the visual impact of the building. Several buildings today comprise of copper sheets because of the beneficial characteristics it contains.

2. In fact, copper was used as a roofing material on a large scale in the 19th century. With the prominence of mechanization and standardization in the production of sheets, the material started to be used increasingly. Reasons For Copper Roofing: Apart from the historical use of copper, sheets of copper are even used today in order to form roofs. In fact, here are some of the top reasons for its use as a roofing metal.

3. 1. Water resistant covering: These sheets of copper act as great protective layer because of its water resistant feature. It is capable of covering even the minimum of joints between two sheets. The roof slopes can be covered at lower pitches in copper compared to other metals. This in turn certainly provides a way for a smooth surface in different forms of architecture. Moreover, with a higher melting point, it is even resistant to fire, and hence can be used in valuable structures.

4. 2. Less density: It is true that several other metals like lead, zinc, aluminum, stainless steel can provide a smooth surface, but the density of copper is lower compared to these metals. In addition to that, copper sheets have greater tensile strength. The combination of these characteristics makes copper thinner and light in weight. Consequently, the amount of structure required for supporting it is less.

5. 3. The protective coating: Since copper has the tendency to corrode it oxidizes to form of a green protective layer. In fact, corrosion of the outer layer protects the layer inside making it last for more than 100 years. The color also creates a prominent visual impact in the buildings. 4. The Installation Of Sheets: As mentioned, there was a time when most of the roofing was carried out with copper sheets, and they were joined at the sides with vertical seams. Clips were attached to the roof in between the sheets. However, with the advancement in technology and development of thin sheets, a system of vertical joints was developed.

6. A wooden roll was used to fix to the roof. The edges of the sheets were turned up so that they could be placed over the welted roll. • Further developments allowed more allowance for thermal expansions making it easy to form junctions. • As time progressed, several experimentation were continued to find out the ideal laying method for these sheets in the roof. • Longer copper sheets are used today for economical reasons. • The method uses long trays of sheet with fewer clips and cross welts compared to the traditional method. • The long standing seams are formed often by machines for greater stability and resistance.
