Metal roofing has been on the architectural scene for over two thousand years. It has been used for its beauty, its durability and its strength. Copper the most widely used material for roofing throughout antiquity has an incredible story attached to it.
Roman’s histories consummate engineers were aware of the many and various ways to put copper to its best use. It was used to clad many parts of buildings including doors, pillars, windows, and roofs. The Pantheon, many believe to be ancient Rome’s greatest engineering victory was completed in the year 27 BC and still stands today. In fact it is the only completely intact structure from this era. The Pantheon has gone through many different phases in its 2000 plus years of Existence. It began its life as the first copper clad roof.
The copper roof on the Hildersheim Cathedral installed in the year 1280 AD still survives to this day, original and not refurbished or restored. Elsinore castle made famous by Shakespeare, completed in 1585 AD was finally redone in 2009.
The earliest form of commercially viable metal roofing was a galvanized product, wrought iron coated with zinc. Later it was rolled into sheets creating corrugated metal still in use today in many developing countries because of its low cost, strength, fire protection and durability.
Metal roofs using aluminum and steel have become commercially viable for the residential housing market in the last fifty years. Commercial buildings and farm buildings have long recognized the intrinsic value of metal roofing and the ultimate value it offers both in cost and protection.
Early examples of metal roofing for the residential market fell short of their promise for a couple of reasons. Methods of fastening shingles together and adequate strapping systems had not been properly developed. Paint and coatings of the day did not possess staying power. Subsequently many of the earlier steel and aluminum roofs did not survive the test of time.
Today’s metal roofs are a whole new pedigree. The interlocking metal roofing shingle has transformed the industry. Where fasteners and joins where once exposed to the elements they are now greatly diminished in number and tucked away inside the system itself ensuring the weakest part of the whole system has the staying power of the rest. Paint and coatings with a little help from Nassau are today not only giving decades of fade free appearance they are actually saving huge amount of energy meaning bank accounts and the environment are being protected.
Kynar a ceramic based paint will last for decades with imperceptible fade. The greatest expense most of us face is the heating and air conditioning of our homes. Air conditioning is exponentially more expensive. Kynar paint actually reflects 90% of the heat from the sun on a hot day back out into the atmosphere keeping the roof and insulation cool and the air conditioner on low.
Metal roofing tile styles have recently emerged that compete with the true terra cotta used throughout much of the world. Slate profiles are being installed that are imperceptible from real slate offering the real look for thousands of dollars less. An average homeowner can now have the slate look and durability for a fraction of the original.
Metal roofing with the use of aluminum and steel has emerged from the lessons of history to offer products with very real value for today’s homeowners.
