Aluminum is extremely resistant to corrosion caused by salt water which is why it is the material often recommended for use in coastal climates. Compared to other types of metal roofs available in the market, the aluminum’s resistance to salt corrosion makes it the best possible option.
In most cases, aluminum roofing is commonly perceived to not be affected by corrosion. But the truth is, this roofing material is a greatly dynamic type of metal and almost immediately respond to the atmospheric environment. The rapid reaction of aluminum to the atmospheric condition is actually what shields it so well. The creation of a layer of aluminum oxide, productively sealing the internal layers of the metal from any subsequent corrosion as the outer layer of aluminum responds with the oxygen in the environment. It is similar to an A606 Weathering Steel process, although in much swift time span and with extensive lasting defense. As its natural patina over time is not thought of as aesthetically engaging, aluminum is often utilized with a painted coating.
Aluminum’s disadvantage often comes down to its high value and not for budget savvy people just like copper. Aluminum roof is more pricey than comparable solutions that use aluminum as a coating, while it can provide a better shield against corrosion. Aluminum’s price range rise and fall, depending on the market as a material. Usually, Aluminum’s price lies around in the midway between steel and copper. Aluminum is mostly used in much thinner diameter than steel for the price.
The factor of cost usually caused in panels that are too thin for their circumstances while Aluminum’s strong point to weight ratio is higher than steel. As such, this can result in damage to the roofing material in areas affected by high winds, hail, or powerful environmental stresses. In choosing the right design and properly spotting the environmental strains that your aluminum roofing will face will be critical.
