This standard lays out the code of practice for roofing with clay roofing tiles of the Mangalore pattern over pitched roofs. It provides specific guidelines on the preparation of the timber framework, appropriate roof pitch, batten spacing, and the correct laying procedures for eaves, ridges, valleys, and hips to ensure durability and weatherproofing.
Code of practice for roofing with Mangalore tiles
Quick Reference Values
Recommended minimum roof pitch30 degrees
Minimum overlap of tiles50 mm
Nominal spacing of battens310 mm to 340 mm (based on tile size)
Minimum overhang at eaves300 mm
Practical Notes
Always lay tiles starting from the eaves and work upwards towards the ridge.
In areas subject to high winds or on very steep pitches, tiles must be securely tied to the battens using galvanized iron or copper wire through the provided holes.
Special attention must be given to mortar pointing at ridges and hips to prevent water ingress without compromising ventilation.
