A damaged roof doesn't wait for a good time to fail. Whether it's a leak after a Canterbury nor'wester, lifted iron after a hard frost, or a roof that's simply reached the end of its life, Oncore Ashburton & Timaru repairs and replaces roofs for homes and rental properties across the district.

We're local. We know how the wind off the Southern Alps and the exposed, open sites around Ashburton, Geraldine, and Timaru put more strain on a roof here than in a sheltered city suburb, and we build our repairs to handle it.

Signs your roof needs attention

• Water stains or damp patches on ceilings, especially after heavy rain
• Missing, cracked, or lifted roof tiles or iron sheets
• Rusted or corroded long-run roofing, particularly around flashings and valleys
• Sagging sections or visible daylight through the roof space
• Moss, lichen, or moisture build-up holding water against the surface
• Gutters overflowing or pulling away from the fascia
• A roof older than 25 to 30 years that hasn't been reassessed recently

If you're seeing any of these, it's worth getting a professional assessment before a small problem becomes a ceiling replacement.

Repair or replace? We'll tell you straight

Not every roofing problem needs a full reroof. In a lot of cases, we can fix a leak, replace a damaged section, or reseal flashings for a fraction of the cost of replacement, and we'll always recommend the option that makes sense for your budget and the age of the roof.

Where a roof has widespread corrosion, repeated leaks, or is past its practical lifespan, we'll walk you through a full replacement, including material options (long-run steel, tiles, or Colorsteel) suited to the local climate and your budget.

What we cover

• Leak detection and repair – tracking down the source, not just patching the symptom
• Roof tile repair and replacement – cracked, slipped, or broken tiles
• Long-run and Colorsteel roofing repairs – corrosion, punctures, lifted sheets
• Flashing repairs – the most common source of leaks around chimneys, valleys, and joins
• Full roof replacements – old roofs replaced end to end, including any timber repairs underneath
• Gutter and spouting repairs – closely tied to roof performance and often replaced at the same time
• Healthy Homes roofing compliance – making sure your rental property's roof meets current requirements

Frequently asked questions

How much does roof repair cost in Ashburton or Timaru?It depends on the extent of the damage and the roof type, but most minor repairs (a few tiles, a flashing reseal, a small leak) are far cheaper than people expect. We'll give you an exact price after a free inspection, not a vague estimate over the phone.

How long does a full roof replacement take?A standard residential reroof typically takes a few days to a week, weather permitting. We'll give you a firm timeframe as part of your quote.

Does my roof need to meet Healthy Homes standards if I rent the property out?Yes, rental properties in New Zealand need to meet Healthy Homes requirements, and roof condition can affect ventilation and moisture compliance. We can check this as part of any roof assessment.

Do you work with insurance claims?Yes, if your roof damage is storm related or otherwise likely to be covered, we can provide the documentation and quotes your insurer will need.
