Ridge caps are roofing materials used to cover the ridge, or peak, of a roof. They help protect the roof from water infiltration and provide a finished look. Ridge caps can be made from various materials, including asphalt shingles, metal, or tiles, depending on the type of roof and aesthetic preferences. These caps are essential for maintaining the integrity of a roof, as they prevent moisture from entering the structure. Proper installation of ridge caps ensures that the roof remains durable and can withstand harsh weather conditions, contributing to the overall longevity of the roofing system.
