A copper roof is one of the oldest in roofing materials. Copper has unique properties that give it an edge over most other roofing materials and make it one of the most sustainable materials for roofing needs. Copper also gives a roof a uniquely attractive look. This is primarily associated with the green hue that develops over time. It gives copper roofed houses an enchanting air. When it comes to sustainability of roofing materials, copper clearly stands out. The sustainability of copper roofing is evident in the following ways.

1. Recyclable

Copper is fully sustainable. It is one of the most widely recycled materials on earth. The high recyclability of copper means that exploitation of existing reserves is slow. Depletion of natural copper reserves is unlikely. Only about 10 percent of the world’s existing copper reserves have been exploited to date. About 75% of all copper ever exploited is still in use today. For those with green concerns, copper is an excellent choice in roofing.

2. Durability

Copper is highly durable. Copper roofing has been known to last centuries. This makes it one of the best choices for roofing. Few roofing materials can endure as long as copper. Once installed, a copper roof will last a lifetime and beyond. Some roofing materials have a short life span. They have to be replaced at some point which adds to your home maintenance costs. Copper tells a different story. Several historic buildings have copper roofs dating back over 100 years. The high durability of copper encourages resourceful natural resource exploitation. Even with its various applications and increasing popularity, there is no danger of copper reserves running out.

3. Resistant to Corrosion

Copper enjoys a high resistance to corrosion whatever the weather. Many roofing materials suffer from underside corrosion. Copper has a natural ability to protect itself. With time, it gradually undergoes a chemical process known as patination. This causes the copper oxide film on roofing to change from reddish-brown to a pale green color. The patina enables the copper to withstand corrosion in any weather. This adds to the durability of copper.

4. Environmental Friendly

Carbon dioxide emissions from copper are minimal compared to other roofing materials. If you choose a copper roof you will make a favorable impact on the ecological balance. It promotes a healthier atmosphere and environment. This is particularly welcome in these days of great concern over climate change the world over.

5. Energy Efficient

Copper roofing rates highly in enabling energy efficiency within the home. Copper absorbs less heat into the home. Copper roofing also radiates less heat. The reflective property of copper enables it to deflect sunlight well. You will appreciate this most during the hot summer months. Copper roofing helps keep the home cooler.

Reduced heat radiation is most appreciable during the winter. You utilize less energy for cooling purposes. This translates to savings on gas or electric bills. Reduced energy consumption in a house is also beneficial for sound environmental management.
