Aluminum and Copper
Aluminum tiles are a great alternative to asphalt or steel shingles because they are much more durable than asphalt and are more resistant to rust than steel.
Aluminum tiles offer a choice of over 70 different colors and patterns.
Aluminum tiles are 100% recyclable. Although requiring more energy to produce than steel, aluminum’s amazing corrosion resistance gives it superior durability and recyclability throughout its lifespan.
Quality of aluminum tiles
Thanks to the anchoring system on four sides and hidden nails, the aluminum tiles can withstand winds of over 200 km / h while maintaining their waterproofness. With the compact layer of oxide that forms naturally on the surface of aluminum, tiles will not rust, rot, warp or chip.
The only drawback of aluminum compared to steel is its fragility to impact. Very large hailstones can add unwanted relief to the tiles, without affecting their durability.
Lifespan: between 50 and 75 years
For over 2,000 years, copper has been used as a roofing material across the world. Whether it’s for its unmatched durability or for its natural finish that oxidizes over the years, copper roofing offers even more!
The aesthetics of copper
Depending on the region, the atmospheric and climatic conditions, copper ages in a unique way. The oxidation of copper on the surface brings a greenish color (verdigris) which forms differently depending on its environment and its degree of exposure to the elements.
To keep the metallic copper finish, you should turn to tinned copper, see below.
The longevity of copper
The first quality of copper is its resistance to corrosion. Examples from the past have shown that the lifespan of a copper roof can be counted in hundreds or even thousands of years. This durability is due to copper’s excellent resistance to corrosion. When the metal surface is oxidized, insoluble, impermeable and very adherent compounds are formed which protect the copper underneath against any environmental aggression.
Lack of maintenance
Copper roofs do not need to be painted or varnished and do not require any special maintenance. The corrosion resistance and strength of copper guarantee exceptional natural longevity. It is the ideal material that will free the homeowner from all maintenance issues.
By establishing the economic balance of copper compared to other roof coverings over a long period of time, copper roofs are by far the most advantageous due to their longevity, lack of maintenance, as well as the added value to the building.
Roofs made of tinned copper have the same properties and advantages as standard copper, except that the latter is coated with a layer of tin to prevent oxidation and thus maintain the copper finish.
