Ridge Cap (Component)

As a roof component, the ridge cap defines the highest line of the roof structure. It marks the junction between two opposing sloping roof planes and must be sealed to prevent water, wind, and debris from entering the roof cavity at this exposed point. The ridge cap component differs from the ridge cap material in that it encompasses the entire assembly — including the ridge board or bracket that provides the fixing substrate, the cap pieces themselves, and the sealing materials (mortar, foam strips, or flexible pointing). On tile roofs, the ridge cap assembly consists of a timber ridge board running along the apex, onto which individual ridge cap tiles are bedded with mortar and pointed with flexible compound. On metal roofs, the assembly comprises a timber ridge board or steel angle bracket, foam closure strips that seal the corrugation gaps, and a formed metal ridge cap screwed through the closures into the ridge board. In Gippsland, the ridge cap is one of the most maintenance-critical components on any roof. Its position at the apex makes it the most exposed point on the building — subject to the highest wind speeds, greatest UV exposure, and the most extreme thermal cycling. Town & Country Roofing inspects the ridge cap assembly during every roof inspection and includes complete re-bedding and re-pointing of tile ridge caps in all restoration work.
