Say Goodbye to Roof Leaks

Why Roof Waterproofing is Essential in Singapore

Prevent Water Leaks and Structural Damage

Singapore’s frequent rain and unpredictable weather can cause water leaks that weaken your roof, leading to cracks, mould, and even ceiling damage. Roof waterproofing prevents water infiltration, protecting your home’s structure and interior.

Extend the Lifespan of Your Roof

A well-maintained roof with proper waterproofing can last for decades without significant repairs. Roof waterproofing solutions create a durable barrier that reduces wear and tear caused by moisture and temperature fluctuations.
Reduce Maintenance and Repair Costs

Fixing roof leaks and water damage can be expensive. However, professional waterproofing services can prevent problems before they occur and avoid costly repairs.
Improve Energy Efficiency

Waterproofed roofs reflect heat, keeping indoor spaces cooler. This reduces the load on air conditioning systems and lowers energy bills, making your home more sustainable.

Our Roof Waterproofing Services

At Allstar Waterproofing, we offer comprehensive roof waterproofing solutions tailored to different types of roofs.

Flat Roof Waterproofing
Flat roofs are prone to water pooling, leading to leaks and structural damage. We use advanced waterproofing membranes and coatings to protect flat roofs in flats, commercial buildings, and industrial properties long-term.

Metal Roof Waterproofing
Metal roofs, commonly found in factories and warehouses, can develop rust and leaks over time. Our specialized waterproofing treatments prevent corrosion, ensuring the longevity of your metal roofing.
Tile and Slate Roof Waterproofing

Tile and slate roofs add beauty to landed properties but are susceptible to water seepage. We apply high-quality sealants and protective coatings to maintain durability while preventing leaks.
Roof Leakage Repair

If your roof is already leaking, we provide fast and effective roof leakage repair services to seal cracks, fix damaged areas, and prevent further water damage.
Green Roof Waterproofing

Green roofs are popular for eco-friendly buildings but require specialized waterproofing to prevent soil moisture from penetrating the roof structure. We use high-performance waterproofing systems to keep your green roof leak-free.

Advance Waterproofing Techniques We Use

Cementitious Waterproofing
Cement-based waterproofing is best for reinforced concrete roofs and provides strong resistance to water penetration.
Torch-on Membrane Waterproofing
Torch-on membranes are a highly effective method for flat roofs. They create a durable waterproofing layer that withstands extreme weather conditions.
Polyurethane (PU) Waterproofing

PU waterproofing is a flexible, durable solution that seals even the smallest cracks. It’s ideal for concrete roofs, flat roofs, and terrace waterproofing.

Urethane Waterproofing

Urethane waterproofing is a high-performance liquid-applied waterproofing system that creates an elastic, seamless, and durable membrane. This method is ideal for roofs exposed to heavy foot traffic, extreme weather, and UV radiation.

We have a leaking complaint from our downstairs neighbour, and our MCST maintenance team said it's likely a waterproofing problem, so I called up Allstar for site visit and quotation. Mr Johnson Chin came and looked around for about an hour to evaluate the problem and assessed that the root cause is leaking water supply pipe. He suggested us to engage a plumber instead. Throughout the whole site visit, he was patient, climbing up and down between 2 houses and also gave advices to our other leaking matters. Although we did not engage their service, I am impressed and thankful for the service and advices provided by Johnson.

I encountered water seapage issue in my terrace on my second floor leading to my main door entrance last year in 2020. Went through a frantic search and managed to meet the manager Wein of ALLSTAR Waterproofing & Services. After engaging Allstar to have the fault rectified & repaired. The leak was totally stopped. The workers assigned were responsible and also ensured proper repair work was indulged. No slip short shabby work which I was very impressed. The manager himself also attended to site inspections to assure proper rectification was conducted. After a year has passed. The repair was so satisfying and despite heavy downpour, the repair shows no weakening. In summary, I highly praise ALLSTAR 's team and highly recommend them. In fact, had already recommended a few friends to ALLSTAR and they too are very satisfied with their professionlism.
