When October rolls around and the first heavy downpours hit Sanur, old villa roofs start showing their age. A small drip under the eaves can turn into ceiling damage within a single day. The good news is that most leaks are straightforward to fix once you know where to look.
Finding the Leak
Start inside. Turn off the lights in the affected room and use your phone torch to trace the wet patch back toward its source. Water rarely falls straight down; it runs along rafters before dripping, so the stain may be metres from the actual hole.
Climb onto the roof (or ask someone to) during or just after rain. Walk the ridge line first—loose or cracked ridge caps are the number-one culprit on older Sanur villas. Then check the valleys where two slopes meet, and the area around any chimney, vent pipe, or skylight flashing.
If you cannot safely get up there, take photos of the interior water mark and the nearest gutter from the ground. That is usually enough for a technician to narrow things down.
- Check gutters for blockages; overflow backs up under tiles and finds its own way in.
- Look for missing or shifted tiles near the eaves where wind lifts them.
- Inspect the felt or bitumen layer if visible at the edges.
Tile Roofs
Most pre-2010 villas in Sanur sit under clay or concrete tile roofs. After ten or fifteen years of salt-laden sea air, the galvanized nails holding each tile corrode and snap. Tiles then shift, crack, or simply fall away, leaving gaps that let monsoon rain straight through.
Walk the roof carefully—wet tiles are extremely slippery. Press gently on each tile near the leak point; if it rocks or lifts more than a centimetre, it needs re-nailing with stainless-steel or plastic-coated fasteners. Replace any cracked tile rather than trying to glue it back together.
The ridge caps deserve special attention. On older roofs they are often just stacked tiles held by wire. A single broken cap can channel an entire afternoon's rainfall into your living room.
Snap a photo of the wet patch or the damaged tile, send it over on WhatsApp, and you will get a straight answer on what needs doing and roughly what it involves.
Thatched and Palm-Leaf Roofs
A fair number of Sanur properties still carry traditional palm-leaf (ijuk or alang-alang) thatch. These roofs breathe well in tropical heat but need re-thatching every five to eight years depending on sun exposure and how close you are to the coast.
A leaking thatched roof usually means the lower layers have rotted or been blown apart. You will see dark, damp patches where the leaves have turned to mush. Unlike tiles, you cannot patch a small hole; the affected section needs to be stripped back to the bamboo lath and re-layered.
If the leak is minor and the rest of the thatch looks sound, a temporary cover buys you time until a proper re-thatch can be scheduled—ideally before the next wet season peaks.
A Quick Temporary Fix
Rain is not going to wait for a roofer's calendar. While you arrange a permanent repair, protect the area:
A bead of silicone sealant around a cracked tile or flashing can hold for a day or two, but do not rely on it through a full monsoon week.
- Lay a heavy-duty tarpaulin over the damaged section, weighted with bricks or sandbags at the edges so wind does not peel it off.
- Run a hose from under the drip point into a bucket to keep water off your ceiling and electrical fittings.
- If you smell burning plastic or see scorch marks near wiring, stop using that circuit and call an electrician before anything else. Water plus live wiring in a Bali villa is a genuine shock hazard.
Getting It Repaired Properly
For anything beyond a single loose tile, bring in a local roofer who works in Sanur regularly. They will know which suppliers carry replacement clay tiles, stainless fasteners, or quality ijuk bundles, and they will have the right scaffolding for steep pitches.
Send clear photos of the leak—both inside (the stain) and outside (the suspected gap)—on WhatsApp. A good technician will quote based on what they see; the final price depends on how much material is needed and how high the roof sits. Ask whether the quote includes removal of old nails, disposal of broken tiles, and a follow-up check after the first heavy rain.
Once the repair is done, walk the gutters and make sure nothing is blocking flow. In Sanur's dry season the debris from coconut palms and frangipani trees clogs channels quickly, and that back-pressure is a common reason 'fixed' roofs start leaking again by November.
Questions
How long does a typical roof repair take in Sanur?
A single-tile swap or ridge-cap fix can be done in an hour or two. Re-thatching a section takes a full day or more. The exact time depends on roof pitch, access, and how many tiles need replacing—the technician confirms this after seeing your photos.
Can I use PDAM water to rinse the roof before repairs?
You can hose off leaves and algae, but avoid high-pressure jets on clay tiles—they are brittle and can crack under concentrated force. Rinse gently from the eaves upward so water flows off the edge rather than forcing itself under the tiles.
My villa has a rooftop tank. Could the leak actually be coming from there?
It is possible. A cracked tank base or a failed overflow pipe can drip onto the roof surface and mimic a tile leak. Check the tank's underside and the overflow outlet first; if they are dry, the problem is in the roofing itself.
I'll reply with what's needed, a price and when I can come.
