Wagner Roofing Co. constructed a steeple for Holy Redeemer Church with a welded aluminum frame, 3/4-inch plywood sheathing, self-adhered membrane underlayment and 20-ounce flat seam copper cladding.Wagner Roofing Co. constructed a steeple for Holy Redeemer Church with a welded aluminum frame, 3/4-inch plywood sheathing, self-adhered membrane underlayment and 20-ounce flat seam copper cladding. The original 40-foot-tall steeple was blown from its 80-foot-high pedestal during a storm in June 2012. The steeple failed due to years of water penetrating the painted metal skin.

Wagner Roofing worked with Simpson Gumpertz and Heger, a structural engineering firm, to assess the condition of the existing masonry bell tower structure. Wagner Roofing also worked with Euramax International Inc.'s CopperCraft to design and fabricate a replacement copper-clad steeple.

The lead-coated copper roof was removed and replaced with 20-ounce copper standing seam attached to a repaired structural deck. The steeple was fabricated and shipped to the job site in two sections, a 30-foot-long main steeple section and 8-foot copper cross. The roof was built with approximately 1,000 square feet of 17-inch-wide, 20-ounce copper standing seam metal roof panels supplied by Wagner Roofing. The copper was rollformed and mechanically seamed in the field.

The new steeple was designed to have an improved attachment to the concrete-framed structure of the bell tower and shed water well away from the central attachment location. The aluminum frame provided a solid base for custom-sized, shop-fabricated flat seam copper panels. The steeple was attached to a structural steel frame that tied back to the original concrete structure. The base podium for attachment of the new steeple was built as part of the overall prefabricated unit and shifted the flex point to within the bell tower. This enabled the copper roof to be completely tied into the steeple and eliminated any potential locations of water infiltration. The project was completed in October 2014.
