Roof waterproofing and heat insulation in Lahore

Lahore roofs face 45°C+ summers and monsoon rain. Leaks and heat are cheaper to stop at construction than to repair.

Waterproofing basics

• Proper slope (about 1:100 or more) towards drains.
• A membrane or coating layer, lapped up the parapet walls.
• Water test (ponding) for 24–48 hours before tiles.
• Rainwater outlets with gratings, sized for heavy monsoon rain.

Heat insulation

• Insulation boards (e.g. XPS/EPS) above the slab, under the screed and tiles.
• Light-coloured reflective top finish.
• Insulation reduces AC load noticeably on top floors.
