| DESCRIPTION: |
Historically copper is often the material of choice for roofs,
cladding, interiors, and fixtures in church construction. However
the perception that copper can be overly expensive has caused
those responsible for some churches to consider other materials
of less proven durability. Copper’s wonderful natural beauty is
enhanced when its life cycle cost is compared to other roofing
materials, and it becomes competitive with other roofing products.

These facts led architect Allan Avis to recommend to the Parish
of St. Justin’s that they select a copper roof to replace the
14-year old prefinished galvanized steel roof on their Church.
The system they chose is a relatively new type of copper shingle
distributed by CastleTop Metal Tiles. Eventually 25,000 pounds
(11,000 kg) of the shingles were installed by Roof Tile Management.
CastleTop’s shingles are formed from 16-oz sheet copper into a
square, which is then laid in a diamond formation, giving the
appearance of scales as they progress up the surface of the roof.
The ridges and spire of the Church are clad in 16-oz copper using
flat seams. The existing structural steel deck was left in place
and covered with a continuous layer of rigid insulation and then
plywood to form the deck for the copper. Copper nails and hardware
were used throughout to fasten the assembly.
