It is necessary to make a continuous crate under the roof (OSB, chipboard, plywood, boards). For moisture resistance and tightness, ondulin sheets are overlapped (2 waves and 30 cm vertically). Before installation, the functional area and the required amount of roofing material are calculated. Discharged board (45 cm step) lathing is suitable for a slope of 10-15 degrees. Ondulin is mounted with an overlap (1 wave and 20 cm vertically). For a pitch of more than 15 grams, a plank (60 cm step) lathing is suitable.

The installation of the sheets should begin from the leeward side from the bottom row with a whole sheet.
