Waterproofing

Dr. Fixit, Pidilite, Asian Paints SmartCare: popular waterproofing। ₹20-40/sq ft। Essential in India — monsoon leaks are the #1 home maintenance issue।

⚡ CalcWolf Insight

Architectural (dimensional) shingles cost only 15-25% more than 3-tab but last 30-50 years vs 20-25 years. They also offer better wind resistance (130 mph vs 60-70 mph) and significantly improve curb appeal. The upgrade pays for itself in avoided re-roofing costs.
