Roof Leakage Repair in Delhi NCR

Permanent Roof Leakage Repair Services in Delhi NCR

Bhawani Technologies provides permanent roof leakage repair in Delhi NCR for residential homes, apartment blocks, commercial buildings and industrial structures. If your roof leaks every monsoon despite repeated patch repairs, the problem is not the paint — it is the underlying waterproofing system, which needs a professional fix.

Our approach starts with a free, detailed inspection using moisture meters and visual diagnosis — so we identify the exact source of leakage before touching a single tile. We then apply the correct system, not a temporary paint-over fix that fails in the next rain.

Why DIY and Paint-Based Fixes Always Fail

Most homeowners try waterproof paint, bitumen paint or putty to fix a leaking roof. These work for 3–6 months at best. The reason: they sit on the surface and cannot bridge the cracks and movement in the concrete slab caused by temperature changes and building settlement. A system-based solution — membrane or PU coating — bonds to the substrate, bridges cracks and creates a continuous waterproof barrier that lasts 7–15 years.

Common Causes of Roof Leakage in Delhi

• Cracks in the roof screed or concrete slab — very common in buildings over 10 years old
• Deteriorated or failed waterproofing joints and laps
• Blocked or poorly designed roof drains causing water ponding
• Parapet wall cracks at the roof-wall junction — a major leakage point
• Corroded or poorly sealed pipe penetrations through the roof slab
• Age-related failure of original waterproofing — most systems last 5–8 years without maintenance

Our Roof Leakage Repair Methods

APP/SBS Bituminous Membrane: A 4mm torch-applied membrane applied in two layers. Creates a completely waterproof, durable barrier. Best for large roof areas with significant cracking or older failed systems.

PU (Polyurethane) Liquid Waterproofing: A seamless coating system with high elongation — bridges cracks up to 3mm. Excellent for roofs with complex details, multiple pipes or service penetrations. UV-stable and flexible in Delhi's temperature swings.

Injection Grouting: For active leaks through concrete cracks, we use polyurethane foam or epoxy injection to seal the crack from inside under pressure. Fast-setting and permanent.

Acrylic / Polymer-Modified Coating: A cost-effective maintenance solution for minor surface cracks and hairline leakage. Suitable as a top-up treatment on relatively new roofs with minor issues.

Frequently Asked Questions

Q: My roof leaks only during monsoon. Does it still need waterproofing?
A: Yes. Monsoon-only leakage means the waterproofing is partially failing. If left untreated, the damage accelerates each season. The best time to repair is before the monsoon (March–May).

Q: How long will the repair last?
A: With a proper system-based repair, 7–15 years is achievable. All our work comes with a written warranty.

Q: Can you do the repair without demolishing the roof tiles?
A: In many cases yes, especially with PU liquid systems. Our engineer advises after inspection.
