If one of my children was graduating from college today, and he or she was interested in a career in roofing, I might likewise give them one word of advice: Metal.

In the fall of 2014, the Jimmy and Rosalynn Carter Work Project (CWP) with Habitat for Humanity International (HFHI) continued the annual tradition in Dallas and Fort Worth, Texas.

One of the perks of being an observer of the roofing industry is the ability to occasionally take advantage of unique learning opportunities.

Something new may be learned from nearly every retrofit roofing project. Every roofing project is completed with different materials in different places on different structures and often with different clients. The renovation of the roof and parapet of the Green-Meldrim House in historic downtown Savannah, Ga., is one project that provided more than its share of lessons.
