Our approach · What you get
Get the Right Fix for Your Roof Leak
Every roof leakage repair job starts with an inspection of the affected area. You will know what is causing the roof leak, which repair method suits your roof, and what you are paying for before you decide.
Find the Source of Your Roof Leak
Our roof leakage specialist checks the roof surface, cracks, waterproofing membrane, joints, gutters and drainage to find where rainwater is entering and recommend the repair work needed.
Avoid hacking where you can
Some roof leakage problems can be repaired without hacking the existing roof surface. PU injection, crack sealing or roof joint repairs may be used where suitable. You will know if non-hacking roof leak repair is possible before work starts.
Know what you are paying for
Get a roof leakage repair quotation based on the actual roof condition, source of the leak and repair work needed, not a guess made over the phone.
Understand your warranty
The workmanship warranty, its duration and conditions are explained before work begins.

The problem · Why leaks get worse
Is a Roof Leak Damaging Your Home?
Rainwater entering through cracks, damaged roof joints or worn waterproofing membranes can cause water seepage through the roof slab. The leakage may show up as water stains or damp patches on ceilings and walls, away from where the roof leak starts.
Water stains or dripping from the ceiling?
A damaged roof waterproofing membrane can let rainwater seep through the roof surface and into the building below. You may notice ceiling water stains, damp patches or dripping water during or after heavy rain.
If ignored: water keeps soaking into the ceiling and the damaged area keeps growing.
Water pooling on the roof?
Blocked roof gutters and poor drainage can cause rainwater to pool on the roof. Water left standing may seep through damaged joints, cracks and weak areas of the waterproofing membrane, causing roof leakage.
If ignored: water works its way into the roof slab and the rooms below.
Mould, peeling paint or musty smells?
Hidden leaks keep ceilings and walls damp, causing mould, peeling paint and musty odours. Repainting or cleaning does not fix where the water is getting in.
If ignored: you keep paying for surface repairs that never fix the cause.
You deserve to know what is causing your roof leak before spending money on repairs.
Frequently asked questions
Answers to common questions about roof waterproofing in Singapore.
Non-hacking methods such as PU injection, crack sealing or other waterproofing work can be used for suitable roof leaks. If the existing waterproofing layer is badly damaged, more extensive work may still be needed. This is checked during your free inspection.
For urgent cases, you can get a same-day or next-day inspection and repair. WhatsApp photos of the leak so the urgency can be assessed quickly.
Common signs include water stains on ceilings or walls, dripping water during or after rain, peeling paint, mould, musty odours and water pooling on the roof or around drainage areas. An inspection helps find the likely source.
Heavy rain can expose cracks, damaged waterproofing membranes, leaking joints and poor roof drainage. Water may enter through one part of the roof and appear as stains or dripping water somewhere else. We check the roof to find where the water is getting in before recommending repairs.
The roof leakage repair method depends on where water is entering and the condition of the roof. We may use PU injection to seal suitable cracks, apply a roof waterproofing membrane, repair leaking roof joints or fix gutter and drainage problems. You will know which repair method is recommended and what the warranty covers before work begins.
Yes, a damaged roof waterproofing membrane may be repaired or replaced, depending on its condition and the affected area. We will inspect the roof first to check whether a localised repair is suitable or whether more extensive waterproofing work is needed.
A proper repair targets the identified source of the leak, but results depend on the actual cause, site condition and repair scope. Assessing the area first lowers the risk of treating only the visible symptoms.
Roof leak repair cost in Singapore depends on where water is entering, the size and condition of the affected roof area, accessibility, materials and the repair method needed.
