Ridge capping by roof profile
Ridge capping covers the apex where two roof slopes meet and sheds water down each side. Match it to the sheet profile first, then pick Colorbond to match the roof colour or Zincalume for an unpainted finish. The flat ridge flashings are 0.55 mm BMT steel, cut to the length you order with a +200 mm / -0 mm tolerance and priced per lineal metre.
Corrugated roofs. The 140 mm flat ridge is shaped for a 20 degree pitched corrugated roof, and the 190 mm flat ridge suits other pitched corrugated roofs. For a rounded finish, the roll top ridge capping is 0.42 mm BMT Zincalume. It is fixed with 12 x 50 roofing screws every second corrugation and is best suited to a 22.5 degree pitch.
Trimdek roofs. The 170 mm flat ridge sits over the Trimdek ribs. The 220 mm Trimdek ridge capping is a rolled 30 x 220 x 220 x 30 mm profile, and its measurements can be changed to suit.
Klip-Lok roofs. The 210 mm flat ridge measures 40 x 210 x 210 x 40 mm, and the 260 mm gives wider cover at 40 x 260 x 260 x 40 mm.
Notch the capping to sit over the ribs with the notchers in metal roofing tools. Barges, aprons and other folds are in custom flashing. For a tiled roof, the ridge cover and pointing are in roof tiles.
