SEC C / ROOFING & ENVELOPE
Roofing contractor in Bali
A roof in Bali does two jobs: it sheds two metres of rain a year, and it does so while being grilled by equatorial UV and shaken by the occasional tremor. We build new roofs and replace failing ones — structure, covering, insulation and gutters as one engineered system, not four subcontractors pointing at each other.
- New roofs & full re-roofing
- 10-year workmanship warranty on structure
- Gutters & rainwater design included
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.
SCOPE OF WORK
What's included
Roof structure
Light-gauge steel or treated timber trusses, engineered for span, covering weight and wind uplift.
Covering installation
Metal sheet, clay/concrete tile or shingle laid to manufacturer specs — laps, fixings and expansion allowed for.
Flat roof systems
Concrete decks with screed-to-falls, waterproofing membrane and protected outlets.
Flashings & detailing
Ridges, valleys, wall abutments and every pipe or cable penetration sealed as a detail, not with a tube of sealant.
Gutters & downpipes
Sized from rainfall data for your actual roof area, with leaf protection where trees demand it.
Insulation & ventilation
Reflective and bulk insulation options plus ridge/eave ventilation that keeps rooms measurably cooler.
PROCESS
How the job runs
- 01
Inspection & measurement
We survey the existing roof or drawings, measure catchments and photograph problem points — free, island-wide.
- 02
Engineering & quote
Structure calcs, covering options at two or three price points, and a fixed itemised quote.
- 03
Build or replace
Our own roofing crew installs structure, covering, flashings and gutters; occupied buildings are sectioned and protected.
- 04
Water test & warranty
Hose-testing on valleys and penetrations before we leave, plus a written warranty on structure and workmanship.

Roofing in Bali — what owners ask
Which roof covering lasts longest in Bali?
Properly fixed clay tile and quality colour-coated steel both give 25+ years here. Steel wins on weight, speed and cyclonic fixing; tile wins on heat mass and looks. What actually decides lifespan is the detailing — fasteners, flashings and gutters fail years before good coverings do.
Can you re-roof while we stay in the house?
Yes — that's the normal case. We open and close the roof in sections, never leave it exposed overnight, and use interior protection where ceilings come down. Most families notice noise more than disruption.
Do you fix leaks, or only build full roofs?
We do both, honestly. If a leak needs a flashing rebuilt rather than a new roof, that's what we'll quote. Chronic leak patterns usually trace to design faults, and we'll show you photos of exactly what we found before recommending anything bigger.
How much does a new roof cost in Bali?
As a guide: complete metal roof systems from IDR 485,000/m², clay tile systems from IDR 650,000/m², including structure. Flat concrete roofs price by deck and membrane spec. Every quote is fixed after a free inspection — the guide prices exist so you're not negotiating blind.
