The under ridge is a vital component of roof systems for water insulation. This element is used at the junctions of sloping surfaces, which are among the most sensitive points of a roof, significantly enhancing the waterproofing performance of the structure. Typically made from galvanized sheet metal, the under ridge maintains its initial performance for many years thanks to its high strength and corrosion resistance.

Especially in regions with heavy rainfall, it prevents rainwater from leaking into the roof, preserving structural integrity and avoiding moisture-related problems. Its easy installation accelerates the application process, and its special design ensures efficient water drainage. With these features, the under ridge has become an indispensable element of modern construction technology.
