| DESCRIPTION: |
This magnificent church, located in Longueuil, recently underwent
an extensive renovation. It included copper being chosen for the
reroofing, rather than galvanized steel which had been replaced
on a number of occasions since 1911.
The architect, Claude Frégeau, compiled an exhaustive study on
similar structures in Quebec and France, concluding that copper
would be the only suitable material from both an historical and
technical viewpoint. Curé Raymond Poisson provided strong support
for changing to a copper roof.

The roof was installed by Les Couvertures Montreal-Nord. It is
a batten seam roof, using 16-oz. copper sheet, and it has a number
of interesting details such as the diamond ribs of the dome. A
mechanical seamer was used for the batten seams.
The sheet copper was installed over a plywood substrate, with
a membrane and building paper underlayment which is a typical
roof assembly with copper. About 65,000 pounds (28,500 kg) of
roofing copper sheet were needed.
