Cornerstone Bible Church Renews Roof with Metal Shingles

When the old asbestos diamond-shaped shingles began to fail on the Cornerstone Bible Church in Glendora, California, ATAS’ CastleTop was chosen as a replacement. The shape of the .032 aluminum panels, which resembled the original shingles in appearance, was an important factor in their choice of a replacement roofing material. They also loved the idea of the longevity and durability of a metal roof, along with the fire resistance of the panels, a concern due to the southern California location of the church. The metal shingles are more environmentally friendly compared to some other roofing materials, as the aluminum contains recycled content and can be recycled at the end of its long service life. Dustyn Howard, president of Howard & Sons, Inc. in Corona, California, stated that they removed the old asbestos shingles, and the CastleTop metal panels were installed over a solid wood deck. The panels and trims were purchased through RoofLine Supply and Delivery in Burbank, California.

CastleTop aluminum shingles are 15 ¾” x 15 ¾” in size and offer coverage of 13 ½” x 13 ½”. They have an embossed texture with a 70% PVDF paint coating. The shingles are also available in anodized aluminum, copper, and zinc. A minimum roof slope of 3:12 is required for installation. For the Cornerstone Bible Church, two colors, Rocky Grey and Charcoal Grey, were used together to create an aesthetically pleasing pattern on the roof. In addition to a long history of roofing applications, CastleTop shingles are commonly used as a wall cladding, to create unique and colorful facades.

The CastleTop shingles are a great complement to this church’s natural stone walls. Prior to the building’s opening in 1931, members of the church mined rock quarries in the mountains above the citrus farms of Glendora and brought down large stones, out of which they built the Cornerstone Bible Church.

This beautiful project was the third-place winner in the 2019 ATAS Project of the Year competition in the commercial roofs category.
