APP shingles are available in a classic ceramic mineral-finishing version or faced with copper or zinc-titanium, such as Leonardo Copper, Leonardo Zinc-Titanium, and Giotto Copper. The modified-bitumen compound used for the products reportedly has a high adhesion without risk of delamination. It also resists high temperatures. The rectangular Leonardo version has a triple reinforcement (glass tissue/polyester/glass tissue) to resist high mechanical stress. The flexible Giotto copper shingle adheres, almost like cloth, to curved surfaces, emphasizing the architecture of the structure underneath.
