A leaking roof in Malaysian monsoon season is more than an inconvenience — it damages ceilings, ruins furniture, and can compromise structural framing if left untreated. IBS Roofing traces the actual leak source and delivers a permanent fix.
Whether your leaking roof is a tile, metal deck, concrete slab, or commercial flat roof — our specialist team identifies the cause, prepares the substrate properly, and fixes it with the right material for the job.
Most roof problems aren't where the water shows. A wet patch on the ceiling can come from a broken tile or failed flashing several metres away — water tracks along battens before dripping. Cheap repairs patch the visible spot and the issue comes back.
We do it differently. Every roof job starts with proper trace investigation — physical roof inspection, water testing where needed, and damp-meter readings — before we quote. Then we fix the actual cause.
Whether you have a tile roof in PJ, a metal deck in Cheras, an RC slab balcony in Mont Kiara, or a commercial flat roof in Subang — we trace, repair, and back our work with a written warranty.
After 1,000+ projects across KL, Selangor, and the wider Klang Valley, these are the recurring cases our specialist team handles.
Concrete roof slabs developing hairline cracks from thermal movement — water seeps through and drips into rooms below.
Car porch decks leaking through to ground-floor entries. Usually failed waterproofing or active edge cracks.
Upper-floor balcony water tracking through the slab and damaging the ceiling below. We excavate, treat, re-tile.
Patch repair done by another contractor that failed within 1–2 years. Usually poor substrate prep — we redo it properly.
Where the roof meets a parapet or higher wall — flashing failures cause water to track behind the cladding.
Standing water around blocked or poorly graded drains causes membrane fatigue. We re-grade and seal.
Visible cracks in the concrete slab that move with thermal cycles. Treated with PU injection grouting.
Cracks at the parapet–roof junction or failed coping cap mortar. Common on commercial buildings and shoplots.
One specialist team delivering every common roofing service across the Klang Valley.
Broken, slipped, or porous tiles replaced. Ridge cap mortar repointed. Sarking patches where needed.
Failed sealants at overlaps, ridge caps, screw heads, or flashings on PPGI / metal deck roofs.
Wall-to-roof flashing, ridge caps, valley flashings — most leaks are here, not the tiles or panels.
For active concrete cracks in RC slab roofs, balconies, and basements. Seals and remains flexible.
PU acrylic, Bostik, or hybrid membrane applied over concrete roofs, balconies, and car porch decks.
Once the leak is fixed — repair stained ceiling, re-skim plaster, repaint. Often combined as a package.
Every IBS Roofing project follows the same engineered workflow — inspect, quote, prepare, deliver, warranty.
Specialist visits, inspects, traces issues, takes photos.
Itemized written quote with method, materials, and warranty terms — within 1–3 days.
Clean, prep, and repair the failed area before applying new material.
Correct work applied — diagnosed, prepared, and executed properly.
Walkaround inspection, water test where applicable, written 2-year warranty handover.
The difference between a 2-year-and-back fix and a permanent solution is rarely the materials — it's the methodology. We've made specialist diagnosis and proper substrate preparation our standard, not our upgrade.
We find the actual leak source first — not just the visible drip — so the repair targets the real problem.
Every diagnosis backed by photos and damp-meter readings so you see exactly why we recommend a specific repair.
Most repeat leaks are from poor prep. Cleaning, drying, and primer application are non-negotiable.
EPDM, PU acrylic, Bostik, polycarbonate-grade sealants — chosen for substrate and exposure.
2-year workmanship warranty on every repair plus material warranties from manufacturers.
Active leaks during monsoon get priority — site survey within 48 hours and emergency tarpaulin if needed.
Every quote is itemized after free site survey. As a guide, here are typical price ranges across the Klang Valley:
Active leaks get priority. We aim for site survey within 48 hours for monsoon emergencies and can deploy temporary tarpaulin protection the same day if needed. Permanent repair is scheduled around weather forecasts.
Single-spot leaking roof repair typically ranges RM 800–2,500. Multi-spot or flashing-related work RM 2,500–6,000. Full membrane waterproofing on concrete roofs starts around RM 6,000. Every quote is itemized after free site survey — no surprise charges.
Most repeat leaks come from diagnosing the wrong source. Water tracks along battens before dripping, so the visible spot is rarely the actual entry point. Cheap contractors patch where the drip shows. We trace the source first — then fix it once.
Most single-spot work completes in 1–2 days. Multi-spot or full-area projects: 3–7 days. Larger projects (membrane waterproofing, full reroof) typically 1–3 weeks. We provide a clear schedule before work begins.
2-year workmanship warranty on every leaking roof repair job, plus material warranties (sealants typically 5–10 years per manufacturer). All warranty terms are written into every quote.
We cover the entire Klang Valley — Kuala Lumpur (Cheras, Ampang, Mont Kiara, Bangsar, Setapak, Sentul, etc.), Selangor (PJ, Subang, Shah Alam, Klang, Damansara, Cheras Selangor, Kajang, Cyberjaya, Putrajaya), and surrounding areas. Free site survey region-wide.
Our specialist visits your property anywhere in the Klang Valley, takes measurements, traces issues, and sends a detailed itemized quote within 1–3 days.
