Roof & Structural Repair in Bali

What We Repair

Why Structural Issues Can't Wait in Bali

A small roof leak in the dry season is a five-month wet-season disaster waiting to happen — water tracks along beams, rots structure, and ruins ceilings and finishes far from the entry point. Termites work invisibly until a beam is hollow. The honest message we give every client: structural problems are the cheapest to fix early and the most ruinous to delay. Once a villa is sound, it is the right time for the finishing trades — waterproofing and painting, new flooring, or a wider full renovation. We always sequence structure first.

Termites: Map the Damage, Treat, Then Replace the Timber

Termite damage in Bali villas is rarely where it first shows. Mud tubes on a wall or a hollow door frame are the symptom; the colony is usually in the ground or in a roof void where timber touches damp masonry. Our order is fixed: map the damage by sounding and probing every accessible beam, rafter and frame; have the active colony treated; then cut out and replace the damaged timber with treated hardwood — or, where the same spot keeps being attacked, a steel or concrete detail. Only after that do ceilings and finishes go back. Termite treatment with timber replacement typically runs IDR 25–80 million, depending on how far the damage has spread.

Replacing an Alang-Alang Roof

Alang-alang thatch is beautiful and short-lived in Bali’s rain. A neglected thatch roof leaks, sheds grass and becomes a home for rats and insects long before it looks finished from the garden. When we re-thatch, we strip the old grass back to the structure, replace rotten bamboo or timber rafters and battens, and — where the owner agrees — lay a hidden waterproof membrane under the new thatch, so a thin patch of grass no longer means water on the bed. Where the structure is sound and the owner wants less maintenance, we re-roof the house in shingle or tile and keep thatch only on a bale or gazebo.

Rusting Rebar and Spalling Concrete

Coastal villas, especially on the Bukit and along the beach strip, suffer from what engineers call concrete cancer: salt and moisture reach the steel reinforcement, the rebar rusts and swells, and the concrete cover cracks and falls away — usually first on balcony edges, pool surrounds, columns and the underside of roof slabs. Painting over it hides the stain for a season while the steel keeps corroding. The repair is structural: we cut the concrete back past the rusted section, clean the bar, replace or add steel where it has lost section, prime it against rust and rebuild the cover with repair mortar, then seal the surface so water does not get back in. Larger repairs start with a written structural survey — IDR 6.5 million, credited against the work.

What Structural Repair Costs

Because every structural job is different, we quote after a proper inspection — but as a guide, a roof leak repair starts around IDR 8 million, termite treatment with timber replacement runs IDR 25–80 million, and major beam, foundation or re-roofing work is priced from a written survey. A standalone structural survey is IDR 6.5 million, credited against any work that follows. See the pricing page.
