Today, A Copper Roof is Consedered the Best Material for Covering the Roof; For its Installation, You do not Need a Device for Welding. However, it is the Most Expensive of All Existing. The minimum Service Life is 150 Years. This Duration of the “Life” of the Copper Roof is Determined by Increased Chemical Stability of the Metal. A year after Installation, Copper Changes Its Pink-YellowLow Color To Reddish, Then Brown, and Later on a Matte-Black. Twenty Years Later, Copper Acquires a Malachite-Green Tint-Sib A Patina, Which Serves AS AS AS AGAINST DAMAGE AN. Copper Covered with Patina Is Practicallly Invulnerble. Due to the Fact that Copper Changes Colors Under the Influence of Oxidation, The Use of Such a Roof Was Quite Limited. And the Green Shade of the Patina Significantly Limited the Options for the Color Solutions of the Project.
