What to Look for When Choosing a Roof Waterproofing Specialist in Singapore

 Living in Singapore means dealing with high humidity, heavy rainfall, and occasional tropical storms. While the weather here adds to the island’s lush greenery and charm, it also poses a significant threat to the longevity of your property—especially your roof. One of the best defenses against water damage? Hiring the right roof waterproofing specialist.

If you're noticing signs like water stains on your ceiling, mold growth, or dripping leaks after a downpour, it might be time to invest in professional waterproofing services. But with so many contractors and companies offering waterproofing in Singapore, how do you know which one to trust?

In this article, we’ll break down the essential things to look for when choosing a roof waterproofing contractor in Singapore—and how to ensure you’re getting quality service, lasting results, and great value for your investment.

1. Experience and Proven Track Record

When it comes to something as crucial as protecting your home or building from water damage, experience matters. Look for a company with a solid history in the industry and a portfolio of successfully completed projects.

Ask questions like:

  • How long have they been providing roof waterproofing services?

  • Do they specialize in residential, commercial, or industrial properties?

  • Can they provide references or case studies?

A reputable contractor should be happy to share testimonials or photos of previous jobs. At Atlas Works, for example, our years of experience in Singapore’s unique climate have equipped us with the knowledge to handle even the most complex waterproofing challenges.

2. Use of High-Quality Materials

Not all waterproofing solutions are created equal. A durable, long-lasting waterproofing job depends largely on the quality of materials used. A reliable specialist will offer a range of options, including waterproofing membrane roof systems, PU injections, and acrylic coatings.

Make sure to ask:

  • What type of waterproofing membrane or method will be used?

  • Are the materials certified and tested for tropical weather conditions?

  • What is the lifespan or warranty of the materials?

In Singapore’s climate, UV-resistant, flexible, and heat-tolerant materials are key. A substandard membrane might offer short-term relief but fail within a couple of years, costing you more in the long run.

3. Comprehensive Roof Inspection Before Quoting

Any trustworthy roof waterproofing contractor will want to inspect your property before offering a solution or quote. Be cautious of companies that provide estimates over the phone without seeing the actual site.

A proper inspection helps the contractor:

  • Identify the root cause of the water leakage.

  • Assess the type and extent of damage.

  • Recommend a waterproofing system tailored to your roof type (e.g., concrete flat roof, metal deck, tiled surface).

This level of detail ensures you get a customized plan—not a generic fix.

4. Licensing, Accreditation, and Insurance

You should never hire a contractor who isn’t licensed or properly insured. Ask to see:

  • Business registration and licenses

  • Proof of insurance (especially public liability)

  • Accreditation from industry bodies like BCA or bizSAFE

These documents are more than just red tape—they’re signs that the company is serious about quality, safety, and accountability.

5. Warranty and Aftercare Services

What happens if a leak reappears after the waterproofing job is done? That’s where warranties come in. Always ask the specialist:

  • How long is the workmanship warranty?

  • What does the warranty cover—just materials or full repair?

  • Is there a clear process for post-job support?

At Atlas Works, we stand behind our workmanship with a solid warranty plan, and our customer care team is always ready to respond if you need help after the job is completed.

6. Local Knowledge and Climate Expertise

Singapore’s climate is unique, and so are its building materials and roof structures. Local experience means the contractor understands:

  • How monsoon seasons affect different types of roofs

  • What materials perform best under year-round humidity

  • Common structural issues in older HDBs or landed homes

Avoid overseas providers or generalists who aren’t familiar with Singaporean architecture and weather patterns.

7. Transparent Pricing and No Hidden Costs

A professional waterproofing specialist will provide a detailed breakdown of costs—including labor, materials, surface preparation, and any repair works.

Make sure to:

  • Request a written quotation

  • Ask if there are additional charges for scaffolding or cleanup

  • Compare quotes from multiple providers—but don’t automatically go for the cheapest

Remember, the cheapest option may not include high-quality materials or experienced workmanship. It's always about value, not just price.

8. Safety Measures and Compliance

Waterproofing, especially on roofs, involves working at heights and using industrial-grade materials. That’s why safety is non-negotiable.

Ask your contractor about:

  • Safety training for workers

  • Compliance with MOM safety standards

  • Use of harnesses, scaffolding, and protective gear

Contractors who invest in safety typically deliver more professional service and are less likely to cut corners.

9. Flexible Scheduling and Minimal Disruption

Whether you're a homeowner or managing a commercial building, waterproofing work can be disruptive. Choose a contractor who:

  • Can work within your preferred timeline

  • Offers weekend or off-peak scheduling

  • Provides clear project timelines and daily work updates

Professional contractors should respect your space and ensure minimal noise, mess, and interference with your routine.

10. Positive Reviews and Online Reputation

Finally, do a little digital detective work. Search for reviews on Google, Facebook, or forums like HardwareZone.

Look for comments about:

  • Timeliness and professionalism

  • Quality of the waterproofing job

  • Responsiveness to post-job issues

A strong online presence, with a clear website like Atlas Works, is a good indicator of a trustworthy company.
