Copper has been used for a long time as a standard roofing material. Local roofing contractors and homeowners select copper roof panels due to their extreme durability, capacity to resist corrosion, and their visual appeal, which is so appealing to so many homes. Copper roofing date back to the 12th century and continue to be utilized today. Consequently, this demonstrates the durability of copper roofing. In addition to being one of the most durable roofing materials available, copper is also very resistant to damage such as scratches and blemishes. Copper sheets for roofing will boost a home’s energy efficiency by reflecting the sun’s UV rays rather than absorbing them.
Why Do Copper Roofs Change Colour?
Copper is an active metal that interacts with the air and environment when left exposed. This process forms a protective “patina,” a thin coating of corrosion over time. On steel, severe corrosion may eat the metal entirely. However, copper is a whole other story. This layer of oxidation generates a thin, durable covering. This layer prevents copper from further deterioration. Therefore, what is most intriguing and astonishing is that copper’s resistance to corrosion is due to its corrosion! In contrast, when copper is mixed with airborne sulphur molecules, it produces a protective copper sulphate layer against moisture. Once the copper and sulphur compounds are completely produced, the sulphate patina will considerably boost the copper’s durability and longevity by protecting it from air pollutants and corrosion.
Different Types of Copper Roofs
- Continuous Copper Roofing
In addition to copper flashing, continuous copper roofing is one of the most costly and rarest alternatives. Continuous copper roofing is a specialized application planned and manufactured for a specific project. Copper sheets are spread down on a roofing substrate, where they are integrated into a single piece without joints or seams.
- Copper Panels
In contrast, copper roofing panels are far less costly than continuous sheets. Copper panels are segmented sheets of a specified width assembled by hand with visible seams. Copper roofing with standing seams is a common method for securing the roof’s seams. Other roofing seams are brazed or welded on-site, making this seam unique.
- Copper Roofing Shingles
Copper roofing shingles are one of the most popular materials due to their inexpensive cost. In contrast to continuous copper roofing and panels, copper shingles are hand-applied in the same manner as conventional shingle roofing materials. However, in general, copper has a soft surface, which necessitates extreme caution during installation since it will likely be damaged. Copper fasteners are essential when installing copper roofing shingles to avoid metallurgical reactions when other metal items come into contact with the copper roofing.
Advantages Of Copper Roofing
Copper roofing is among the most advantageous materials, alongside asphalt and slate. Regular care and maintenance greatly aided copper roofing’s extended life expectancy. If the copper roof is maintained correctly, its expected lifespan may be extended by fifty years. In addition to being advantageous and having a fifty-year lifespan, copper roofing is also resistant to the weather. Copper roofing would thus be less susceptible to rain, hail, and mildew, and it is one of the most fire-resistant materials available. Copper is also resistant to heat fluctuations, so it would not degrade as rapidly.
Numerous commercial roofing contractors are always searching for new energy-efficient and eco-friendly methods of extending the roof’s lifespan. However, copper roofing has become one of the most popular materials in recent years. Because metal reflects rather than absorbs heat, copper roofs simplify homeowners to regulate their heating and cooling expenses. Copper is recyclable; consequently, it is highly suggested to reduce your environmental imprint. It is also a relatively lightweight material, making installation fast and simple. In addition to being lightweight, the copper roof is flexible, making it simpler for contractors to install regardless of the roof’s uneven or irregular form.
