Ridge Capping

Ridge capping is the final weatherproofing element installed along every ridge and hip line on a roof. On metal roofs, ridge caps are formed from matching Colorbond or Zincalume steel and are screwed to a timber ridge board or directly to the top of the roof sheets, with foam or rubber infill strips beneath to seal the corrugation gaps. On tile roofs, ridge caps are individual cement or terracotta pieces that are bedded in mortar and pointed with flexible compound. The ridge capping process on a new metal roof involves running the roof sheets to within 50mm of the ridge apex on each side, installing a ridge board or angle bracket at the apex, laying foam closure strips along the top of the sheets, and then screwing the formed ridge cap through the closure strips into the ridge board. The caps are overlapped in the direction away from the prevailing weather to prevent wind-driven rain from entering the overlap. In Gippsland, ridge capping on tile roofs is a major maintenance item. Town & Country Roofing frequently re-caps tile roofs as part of restoration work, and also installs new ridge capping on metal roof installations and tile-to-tin conversions. Proper ridge capping is essential for preventing water entry, wind damage, and pest intrusion at the highest and most exposed points of the roof.
