Rhynehart Roofing, Inc. uses CertainTeed shingles. Hallmark shingles carry a 25 year material warranty and are two-tone, "zebra-striped" in order to simulate a wood grain. From the Hallmark line, you can upgrade to a Carriage House Shingle® which carries 35 year material warranty. This is a slate tile look with curved ends. These shingles look great on a Victorian style home. The "elite" of the composition family is the three layer Grand Manor Shingle™ which also carries a 40 year material warranty. The cost of these shingles range from $115 per square up to $270 per square.
