Complementary elements for covering with corrugated bitumen sheets: a) side sealing of the wall or chimney, b) gable angle, c) roof ridge tile, d) polyurethane gasket, e) transparent PVC plate, f) skylight, g) roof vent

Roof ridge made of bituminous panels.

The ridge of the roof should be covered with ridge tiles made of the same material as the boards and of the same color. Double, elastic, flat wings allow the ridge tile to adjust to roofs with different slopes. Its dimensions and shape are shown in Fig. c. Before installing the ridge tiles’ the highest-level slabs at the ridge should be nailed to the battens, except for the last batten under the ridge.

In roofs with a non-ventilated ridge, the boards should end at the very line of the ridge, while in ventilated roofs, the upper edge of the panels must be withdrawn from the ridge line by a minimum of 2 Cm. Laying ridge tiles should start from the side opposite to the prevailing wind direction (from the leeward side), from gable to gable of the roof. The ridge tiles should be adjacent to each other and overlap one another by approx 12,5 Cm.

The ridge tile is fastened to the highest batten with the same nails as the corrugated sheets, nailing nails through each top wave of plates, in the same order as on the plate joints. The next ridge tile is fastened to the battens previously fixed beyond the width of the overlap.

Gable edges
The end of the roof slope along the gable edge is made using a specially designed angle profile, made of the same material as the corrugated board. The front board (wind) must be attached this way, so that its upper edge coincides with the plane of the upper surface of the roof (Lynx. b). Then the angular profile is nailed in the plane of the slope to years by the top wave, and on the side to the wind plank (peak).
