Why You Should Hire a Roof Waterproofing Expert

Hiring a general contractor or painter may seem cheaper, but a specialist ensures:

  • Proper substrate preparation

  • Material compatibility

  • Long-lasting application

  • Warranty and maintenance plan

Waterproofing isn’t just about applying a chemical; it’s about diagnostics, design, and delivery.

Types of Roofs and Suitable Waterproofing Methods

Concrete Roofs

Often found in urban areas of Pakistan, these need high-flexibility coatings like polyurethane and acrylic-based elastomers.

Metal Roofs

Prone to rust and expansion; require rust-proof chemical primers followed by elastomeric membranes.

Sloped Roofs

Water run-off is easier but requires edge sealing and ridge protection. Bitumen felt and shingles work well.

Flat Roofs

Most vulnerable to pooling. Require layered waterproofing membranes and slope correction.

Heat Proofing with Waterproofing
