Detailed ONDUVILLA® installation guide Supporting structure ONDUVILLA® can be installed on all standard roof structures. Onduvilla® Fasteners Wooden deck (for example OSB) Minimum pitch: 2/12 for solid deck Ridge Slope Rise Eave Run Slope = amount of rise per run Example: 3-in rise per 12-in run = 3:12 Minimum slope required: 2:12 For residential applications, ONDUVILLA® should be installed over solid decking—usually plywood, wood boards, OSB, or planks—with a proper underlayment (felt).
installation principles Start installation at eave. Overlap joints away from entrances and/or away from the point of greatest traffic. This will improve overall appearance. Position the dark strip “shadow line” at the top. Stagger each course at least one corrugation from previous piece. Different visual effects can be created by various staggers of 1, 2, or 3 corrugations. Ensure proper waterproofing by aligning the overlapping guides.

Cut the Apron Piece Verge Piece 2 The Apron Piece is installed on both sides of the roof to secure watertightness. At the verge, the Apron Piece has to be cut on site parallel to the last corrugation of the shingle. 3 For pitches above 8/12, it is necessary to cut the flat part above the corrugations.
hip 1 Carefully cut shingles maintaining proper gap for ventilation. 2 Apply Flashing Band for the first 3’ of hips and then ONDULAIR SLIM membrane for rest of hip. ONDULAIR SLIM Perforated aluminum selfadhesive tape, which provides additional water tightness and assists in the ventilation at hips and ridges.
