Nok Atap
BUILDING MATERIALS & CONSTRUCTIONbeginner
Definition
Ridge or roof ridge cap — the horizontal element that caps the peak where two roof slopes meet. Nok atap is made from tiles (matching the main roofing material), metal flashing (for metal roofing), or ridge cap shingles. It serves both a weatherproofing function and a visual finishing role, often the most visible detail of a roof from a distance.
Example
A genteng-metal roof uses a matching metal ridge cap at the peak — a V-shaped or rounded profile that overlaps the uppermost course of tiles on both sides and is screwed or sealed to prevent water infiltration at this critical junction.
