Why Roof Waterproofing Matters in Singapore

Singapore’s humid climate and heavy rainfall make roof waterproofing not just optional, but essential. A leaking roof can cause serious issues such as mold, electrical damage, and structural degradation. Waterproofing protects your home or property, increases durability, and saves long-term costs.

Roof waterproofing helps prevent costly damage that may otherwise require professional roof leak repair in Singapore.

🧱 Types of Roof Waterproofing Solutions We Offer

We specialize in a wide range of waterproofing systems suitable for different roof types and materials:

1. PU (Polyurethane) Waterproofing

Durable and flexible, ideal for flat concrete roofs and HDB rooftops. It forms a seamless protective layer that prevents water seepage.

2. Bitumen Membrane Waterproofing

Highly effective for industrial roofs and commercial properties, providing strong resistance against UV rays and heat.

3. Liquid-Applied Waterproofing

A cost-effective and quick-drying option for metal and tiled roofs, offering easy maintenance and strong adhesion.

Liquid-applied systems are ideal for polycarbonate roofs, providing seamless protection without damaging panels.

4. Torch-On Membrane System

Perfect for flat roofs and balconies, offering high-performance waterproofing even under intense sunlight and rain.

5. Acrylic Waterproof Coating

An eco-friendly choice that reflects heat, reduces roof temperature, and enhances overall energy efficiency.

🔍 Our Roof Waterproofing Process

We follow a systematic, step-by-step waterproofing process to ensure reliable and lasting protection:

1. On-site Roof Inspection – Identify cracks, leaks, and problem areas.

2. Surface Preparation – Clean, remove debris, and repair damaged areas.

3. Application of Waterproofing System – Apply chosen waterproofing layer (PU, bitumen, etc.) with professional tools.

4. Leak Testing & Quality Check – Ensure complete coverage and no seepage points.

5. Final Finishing – Apply protective coatings and sealants for a clean finish.

💰Roof Waterproofing Costs in Singapore

📌 Typical Price Ranges

Per square metre (sqm) estimates:
(Actual prices vary depending on contractor, site conditions, and warranties.)

📍 Actual Project Cost Examples

Depending on roof area and job complexity, typical total project costs can be:

• Small residential roof (e.g., landed terrace / condo rooftop): $2,500 – $8,500+

• Standard HDB flat roof (approx. 1,200 sq ft): ~$1,800 – $3,200 (liquid membrane)

• Larger landed roofing with high-end membranes: $6,000 – $12,000+

🧠 What Affects Roof Waterproofing Costs

Your final price depends on several factors:

• Roof Size & Shape: Larger roofs may enjoy reduced rate per sqm, but complex rooflines (slopes, gutters) increase labour.
• Surface Condition & Preparation: Old waterproofing removal, crack repairs, or drainage corrections add cost.
• Method & Materials: Premium membranes (PU, torch-on or multi-layer systems) cost more than basic liquid coatings but last longer.
• Accessibility & Height: Ladders, scaffolding, or safety harnesses for high-rise access can increase labour charges.
• Warranty & After Service: Longer warranty periods often reflect higher quality products and installation costs.

❓What is Roof Waterproofing?

Waterproofing is the treatment of a surface to prevent the passage of water under hydrostatic pressure or the process where a building component is made totally resistant to the passage of water and/or water vapor.

Our specialists are professionally trained in waterproofing which helps to prevent water from entering and is the long-term solution to prevent roof leak.

The conventional system of waterproofing involves ‘membranes’. This relies on the application of one or more layers of membrane (available in various types of materials: e.g. bitumen, silicate, PVC, HDPE, etc) that act as a barrier between the water and the building structure, preventing water ingress.

However, the membrane system relies on the perfect application, which has presented difficulties. As such, problems with the application or when the membrane does not adhere properly to the substrate can lead to leakages.

❗Common Signs of Roof Leakage

• Brown stains or peeling paint on ceilings or walls
• Visible cracks or sagging areas on your roof
• Dripping water during rainstorms
• Mold or mildew smell indoors
• Increased electricity bills due to insulation damage

Why Do You Have to Waterproof Your Roof?

Water damage is one of the most common problems that people experience in their homes. Furthermore, the longer the water sits over time, the worse the damage becomes.

Immediately addressing water problems can often save hundreds of dollars in damage repair costs and prevention is better than cure.

What are the Consequences of a Leaking Roof?

Leakage might corrode the metal reinforcement within the concrete itself. Moreover, a leaking roof might destroy furniture, expensive floorings, and might create a foul smell within your household.
