Monsoon drainage critical। Flat roofs need proper slope (1:100 minimum)। Downpipes: 1 per 10-12m gutter। Many Indian homes lack proper rainwater drainage — causes wall damage, seepage, foundation issues।
Rainwater Harvesting

Foundation damage from poor drainage costs $5,000-30,000 to repair. Properly sized gutters and downspouts with extensions cost $1,500-3,000 installed. This is one of the highest-ROI home improvements — protecting your foundation protects your largest investment. Check your gutters during the next heavy rain and note any overflow points.
