CertainTeed. Eligible for a 30% tax credit up to $1,500, Landmark Solaris reflective asphalt roofing shingles help reduce energy costs by lowering the temperature of a home’s roof by as much as 20% in the summer, the maker says. The reflective technology also reduces “thermal shock,” the expansion and contraction of exterior building materials, helping roofs maintain structural integrity. Available in five brown and dark gray hues, the product line gives homeowners color options not available with other cool shingles, which are often limited to light or white colors. 800.233.8990. www.certainteed.com.
