Roofing contractor in Bali

Most roof problems we're called to fix were built in on day one: undersized gutters, tile laps that assume drizzle rather than a cloudburst, steel battens that started rusting the week they were installed. So we begin every roofing job at the drawing stage — calculating rain loads for the real catchment area, choosing fixings rated for coastal air, and detailing the boring parts (flashings, penetrations, valleys) where 90% of leaks are born.

We work across every covering commonly used on the island — colour-coated metal sheeting, clay and concrete tile, asphalt shingle, and reinforced-concrete flat roofs with proper falls and membranes. If your architecture calls for an alang-alang look without the maintenance, we'll show you the hybrid build-ups that deliver it.

What Bali does to roofs

The island's roofing enemies are specific. Rain arrives in bursts of 80–100 mm per hour, which turns undersized gutters into waterfalls that soak walls from the top down. UV at these latitudes chalks cheap coatings within three years. Salt air within a couple of kilometres of the coast eats unprotected fasteners long before the sheeting fails. And afternoon heat cycles make every material expand and contract daily — loosening whatever was fixed without allowance for movement.

None of this is exotic engineering; it just has to be respected line by line. Zincalume-grade steel or better, Class 4 coastal fasteners, laps sized for intensity rather than habit, and movement joints where the maths says so. That's the difference between a roof you forget about and a roof you meet every wet season.

Re-roofing without wrecking your weeks

Replacing a roof over an occupied villa is a logistics job as much as a construction one. We strip and close in sections so the building is never open overnight, protect interiors with temporary membranes, and sequence noisy work away from guest hours where villas trade. A typical 300 m² re-roof runs 3–5 weeks depending on structure condition — and you'll know the schedule before we lift a single tile.

Repair or replace? What we check on site

Many owners call us asking for a new roof when a targeted repair would do — and sometimes the reverse. The inspection decides, and it is free island-wide. We go up with a camera and a moisture meter and write down what we find, so the recommendation comes with photographs rather than opinions:

• Covering: rust and chalking on metal, cracked or slipped tiles, brittle shingles
• Fixings: corroded screws, lost washers, nails backing out of battens
• Structure: termite damage in timber, rust at steel truss joints, sagging ridges
• Flashings, valleys and every pipe or cable penetration
• Gutters and downpipes checked against the real catchment area
• Ceilings mapped for stains to trace where water actually enters

A repair is the honest answer when the structure is sound and the leaks trace to details — a flashing, a valley, a run of failed fixings. Replacement makes sense when the structure is compromised, when the covering has reached the end of its life across the whole roof, or when the drainage was undersized from day one and every wet season proves it. Flat concrete roofs get a flood test and moisture readings first; our note on why flat roofs leak in Bali explains what we look for.
