 Copper
is an excellent choice for roofing material. That's because the attributes
of a good, long-life roofing material include 1) an attractive appearance,
2) high corrosion resistance, 3) minimum maintenance requirements,
and 4) good economy.
Copper combines all of these qualities better than any other roofing
material.
The suitability of copper as a roofing material has been proved over
the centuries. Copper was used for roofs at least as early as 27 BC.
The Pantheon in Rome, for example, was roofed with copper.
Today, copper roofing is often selected because of its attractiveness
and its resistance to extreme weather conditions. Major public buildings,
commercial buildings, and homes use copper for roofing, gutters, and
leader pipes.
The green patina finish that gives copper the classic look of warmth
and richness is the result of natural weathering.
Preservation projects incorporating copper roofs benefit from the
metal's unique qualities and ensure longevity, aesthetic appeal, and
bottom-line economy for restoration, renovation, and replacement.
The characteristic green patina of aged copper roofs has come to represent
classic beauty in architecture. The same patina provides centuries-long
corrosion resistance. Copper has the form and function to fit in all
the right places, old and new.
Copper's unique properties provide a wide spectrum of preservation
solutions for roofs, from spot repair to total replacement.
With a copper roof, the owner gets an unbeatable combination of beauty,
durability, and low maintenance requirements.
Typical shingle roofs last 12-15 years. Architectural grade shingles
can last 25-30 years. Cedar shingles can last 30-40 years. Slate,
tile, and copper shingles last at least for 60-80 years.
Copper is a safe roofing material. After a strong earthquake in Kobe
City, Japan, in January 1995, copper roofs that were installed on
various buildings, shrines, and residences were not damaged. However,
roofs made from clay tiles either buckled, collapsed, or were completely
destroyed. ((see photo above))
Copper flashing (i.e., the waterproofing material installed under
shingles or tiles where two roofs intersect, where a roof abuts a
wall, or around chimneys and vents that penetrate the roof) provides
long-lasting, reliable protection. No other flashing material can
ensure and enhance the performance of a roof like copper. And in coastal
environments where aluminum and galvanized steel corrode quickly,
copper flashing adds extra protection against weathering. |
