Steam bent cedar shingles are made from native cedar trees culled in the Pacific Northwest. Due to the strength of the cedarwood and natural oils that resist decay, they offer excellent durability and can stand up to high winds and hail.
Curved cedar shingles provide homes with a unique appearance reminiscent of something out of the pages of a fairytale. Because of the curving patterns that alternate between every row of shingles, it evokes the past of European villages.
Steam bent shingles are installed similar to regular cedar shakes (PDF). One of the main differences between a cedar roof is how the roofing felt gets installed. Asphalt shingled roofs usually cover the entire sheathing with a layer of felt, then install their shingles.
This is a very time-intensive project. So it should be approached with caution if trying to do it yourself. If you hire a contractor to do this type of roof, be prepared for estimates higher than asphalt.
