A re-roof generates real waste. Here is what happens to old steel, tiles and membrane in NZ, how asbestos is handled, and what responsible disposal looks like.
Re-roofing strips off an entire roof, and where that material goes matters — both environmentally and legally. Old steel, tiles, membrane and any asbestos each have a correct path. Responsible re-roofers plan disposal as part of the job, not as an afterthought.
Steel Is Highly Recyclable
Old long-run steel and metal flashings are valuable scrap and are readily recycled in New Zealand. Sending clean steel to a metal recycler keeps it out of landfill and recovers value. This is one of metal roofing's quiet advantages — at end of life it goes back into the steel stream rather than to waste.
Tiles and Membrane
Concrete and clay tiles are often crushed for hardfill rather than landfilled. Membrane and bituminous materials go to managed waste streams. Sorting waste on site — metal one way, inert material another — reduces landfill volume and cost.
Asbestos Must Be Handled Correctly
Older Auckland roofs and eaves may contain asbestos cement. This cannot go in a normal skip — it must be removed under the correct controls and disposed of at a licensed facility. We identify, contain and dispose of asbestos legally, with documentation, so you are protected as the property owner.
Frequently Asked Questions
Can old metal roofing be recycled?
Yes. Long-run steel and metal flashings are highly recyclable and have scrap value. Responsible re-roofers send clean steel to metal recyclers rather than landfill.
What happens to old roof tiles?
Concrete and clay tiles are often crushed for hardfill rather than landfilled. Sorting them from other waste reduces disposal cost and volume.
How is asbestos roofing disposed of?
It must be removed under correct controls and taken to a licensed disposal facility — never a normal skip. We handle this legally with documentation.
Is disposal included in a re-roof quote?
It should be. Removal and disposal are real costs; we include them clearly so there are no surprises, and we handle any asbestos correctly.
