Our roof waterproofing services

Lin Jin Ze Construction’s rooftop waterproofing services can deal with leakage issues with all types of roofs – concrete, slabs, tiles, and metal. We also specialise in roof terrace, deck, and garden waterproofing.

Roof leakage repair

We provide leak roof repairs to solve problems caused by damage to waterproof membranes, roof flashing, and roof sheeting.

An obvious sign of leakage is water staining on ceilings or walls, but identifying the exact source of the problem usually requires the expertise of a specialist.

Reinforced concrete flat roof waterproofing

Flat roofs can be notorious for leaks, especially those constructed from reinforced concrete (RC), which is porous and therefore susceptible to water incursion.

Our concrete roof waterproofing contractors and flat roof waterproofing and leak repair specialists can provide a long-term solution by applying a waterproofing membrane to seal the roof.

Tile roof waterproofing

Broken or slipped tiles or shingles are often the cause of roof leakage and result in pooling inside the roof, which can seep downwards into a property’s interior.

However, the problem may not be fixed by fitting replacement tiles. The main cause of leakage from a tiled roof can be the underlying membrane – replacing this is far more involved and best left to a tiled roof leak repair expert.

Metal roof leak repair

Most leaks in metal roofs are caused by incorrect fitting of the roofing screws – misaligned, too tight or too loose. Our metal roof repair services also address leakage problems resulting from a breakdown of the stack flashing that provides waterproofing around pipework for venting systems in a building.

Roof terrace waterproofing

Our services include cleaning the surface, repairing weakened substrate, sealing around rainwater outlets, and applying layers of water-resistant coating.

For roof surfaces that are exposed to direct sunlight or require a high level of elasticity, polyurethane waterproofing system can be used.

Roof garden waterproofing

Lin Jin Ze Construction’s roof garden waterproofing service involves thorough preparation of the substrate, including repairing any cracks and applying layers of waterproof coating followed by a final protective layer of water-resistant compound.

We also ensure adequate filtration and drainage.

Roof deck waterproofing

Our service includes concrete roof deck waterproofing, wood and plywood deck treatments, and metal deck waterproofing.

We use high-performance polyurethane coatings that provide a tough, durable, water-resistant surface with good stability in strong sunlight.

No more unwanted water intrusion!

Guided by Lim Sar Tee, an industry expert with 40+ years of experience, we'll ensure your premises are safe from water infiltration.

Cost of roof waterproofing

The cost of roof waterproofing depends largely on the type of roof and roof waterproofing system installed. For example, replacement tiling costs more than waterproofing a concrete roof. Other factors affecting roof waterproofing pricing include the size of the roof and whether scaffolding is needed.

Problems our roof waterproofing contractors solve

Water leaking from a roof can cause immense and costly damage as it travels downwards throughout a building. It can ruin furniture and affect fittings and fixtures and even the structural integrity of the property.

Then there’s the issue of mould development, which poses health hazards such as respiratory problems.
