Cracked or Slipped Tiles
Clay and concrete tiles can crack from debris, age or foot traffic — letting water run straight to the underlayment below.
Stained ceilings, dripping walls, tile damage after a storm — NASAX's leak specialists diagnose the true source of the leak and repair it durably. 24/7 emergency response across Singapore.
The leak you see is rarely where the water enters. Four decades of Singapore roofs have taught us to chase the true source — not just patch the symptom.
Clay and concrete tiles can crack from debris, age or foot traffic — letting water run straight to the underlayment below.
Metal flashing at ridges, hips and walls is the most common leak source in Singapore. Sealant degrades faster in tropical sun.
Gutters choked with leaves and silt force water back under the tiles and into the ceiling during heavy downpours.
Water often enters through wall cracks or parapets and tracks along beams — appearing as "roof leaks" far from the real source.
R.C. flat roofs and balconies lose their waterproof coating over time. Hairline cracks become steady ceiling drips.
Heavy monsoon storms can lift tiles, tear flashing, and expose underlayment — often overnight, from a roof that was fine the day before.
NASAX has refined a straightforward leak-repair process over four decades: diagnose properly, quote clearly, repair durably, document thoroughly.

A specialist visits, often within 24 hours. We inspect the roof, ceiling and walls to identify the true leak source — not just the stain.
You receive a detailed, cost-conscious quotation with the recommended scope of works. No padding, no upsells.
Our licensed crew carries out the repair — tile replacement, flashing re-seal, epoxy injection, membrane patch — using the right method for the cause.
After service, we send photos of the completed repair so you have a record of exactly what was done and where.
