Copper is one of the most historic materials used to this day for roofing. Besides offering a more sustainable roofing structure, it also makes your building look more appealing. Copper roofing comes with many advantages, however, it has a few drawbacks too. Thus, building owners should contact expert roofers to gauge if copper is the right material for your home property.

Copper roofs typically need minimal maintenance compared to asphalt shingles or other metal roof options. Here we will compare both the pros and cons of copper roofs:

Copper Roof Pros

Integrity & Durability

As a roofing material, copper is highly durable and considered one of the most suitable roofing choices. Contrary to steel and aluminum roofing copper does not rust or corrode. Plus, there is no need to coat or add an extra layer of paint. It will stay the same for hundreds of years.

Corrosion protection

Several roofing materials tend to corrode with time, but copper is greatly resistant to corrosion. As time goes by, copper undergoes patination, which is an organic chemical reaction that forms a copper oxide layer on the roof and changes the original warm brown shade of the roof to pale green. This makes copper roofing tolerate corrosion in any climate, increasing its durability.

Safer compared to other roofing metals

Copper, as a roofing material, is less prone to damage as a result of snowfall, heavy thunderstorms, or extra sun exposure. Since it is more lightweight, it is less probable to loosen or get impaired because of snow built-up. Plus, it is fireproof.

Energy Efficiency

Copper roofs tend to withhold and emit lower amounts of heat. The mirroring property of the metal deflects sun rays. This means that your house will be cooler during summer and warmer in the winter, saving you energy and money in the long run.


Unlike other roofing materials, copper emits lower levels of carbon dioxide, making it a more environmentally-friendly option.

Copper Roof Cons

High Cost

Copper is one of the most costly roofing materials and hence, this is why finding a home covered by a copper roof completely is a scarcity. Many owners only use copper roofing at their bay windows, towers, or lower slope parts. It is also used often in flashings and roof corridors.

It’s noisy

Unlike other materials, copper does not control noise. This happens because it is a softer metal compared to others. The noise issue, however, can be controlled with the addition of supporting layers beneath it.

Contraction & Stretch

Copper tends to contract and stretch at certain temperatures, leading to the weakening of fasteners and requiring immediate fixing work. This can be handled during the planning and installation phase, however, it is important to work with an established installation expert.
