Metal Roofing Guide for Nepal: Sheets, Insulation and Flashings

Specify metal roofing by profile, coating, thickness, fasteners, insulation, condensation control, flashings and wind exposure.

Choose the right sheet

Compare base metal thickness, coating mass, paint system and warranty rather than colour alone.

Control condensation

Use insulation, vapour control and ventilation suitable for the building use and climate.

Detail fasteners and laps

Correct washer compression, end laps, side laps and support spacing are essential for durability.

Design flashings

Ridges, valleys, parapets, gutters and penetrations should be fabricated and installed as a system.
