Decramastic Roof Care
Decramastic Roofing in West Auckland
Decramastic roofs are pressed steel tiles finished with a coating of stone chips, and they were a popular choice on West Auckland homes built from the 1970s through to the 1990s. You will see them on plenty of houses in Henderson, Massey, Glen Eden, Te Atatū South and Ranui. They are light and attractive when new, but after decades of sun and rain most are now showing their age. We provide decramastic roofing in West Auckland, from small repairs and maintenance through to full replacement.
The most common problems are chip loss, rust and leaks at the overlaps between tiles. Once the stone chip washes off, the coating underneath is exposed and the steel starts to corrode, usually first along the bottom edges of the tiles. Broken or lifted tiles from foot traffic and storms are also common. Many of these issues can be fixed with targeted repairs, and some roofs can be extended further with a careful roof restoration.
When rust has gone through a large number of tiles, repairs stop making sense. At that point most owners replace the decramastic with long-run steel, which is lighter on maintenance and much easier to keep watertight. We handle that conversion as part of a full roof replacement, and we will always tell you honestly whether your roof is worth repairing or ready to be replaced.

What We Offer
Decramastic Roofing Services in West Auckland
Repairs, restoration and replacement for pressed steel, stone chip tile roofs.
Chip Loss and Rust Treatment
Bare patches and early rust do not always mean a new roof. We treat surface corrosion, prime exposed steel and seal the affected tiles to slow further damage and keep water out for longer.
Decramastic Roof Restoration
For roofs that are still structurally sound, we clean the surface, carry out repairs, treat rust and apply suitable coatings. Restoration can add useful years to a decramastic roof at a fraction of the cost of replacement.
Ridge and Barge Repairs
Ridge caps and barge tiles take the brunt of the wind and often come loose first. We refix or replace them and reseal the joins so wind-driven rain cannot get underneath.
Leak Detection and Repair
Leaks on decramastic roofs usually start at overlaps, nail holes, valleys and penetrations. We trace the water back to its entry point and fix the cause rather than covering the symptom with sealant.
Decramastic to Steel Re-Roofing
When the tiles are past saving, we strip the decramastic, check the battens and framing and install a new long-run steel roof with matching flashings, giving you a lighter, lower-maintenance roof that will last for decades.
Signs Your Decramastic Roof Needs Attention
Decramastic roofs usually show their age gradually. From the ground, look for bare or dark patches where the stone chip has worn away, orange rust stains along the tile edges, and tiles that look lifted or out of line. Loose chips collecting in the gutters are another sign that the coating is breaking down. Inside, damp patches on ceilings or stains near the top of walls can point to water getting past the overlaps.
Small areas of chip loss and surface rust can often be treated before they become a problem. If rust has eaten through the steel across large parts of the roof, repairs become a short-term fix, and replacement is usually the better investment. A roof inspection tells you which situation you are in and what it will cost to put right.

Common Questions
Frequently Asked Questions
Answers to the questions West Auckland homeowners ask us most about decramastic roofing.
What is a decramastic roof?
Decramastic is a pressed steel roofing tile coated with stone chips. It was widely used on New Zealand homes from the 1970s to the 1990s because it was lighter than concrete or clay tiles while keeping a tiled look.
Can a decramastic roof be repaired?
Yes, if the damage is limited. Damaged tiles can be replaced, lifted tiles refixed and surface rust treated. If rust has gone through tiles across much of the roof, replacement is usually more cost-effective than ongoing repairs.
Why is my decramastic roof losing its chips?
The stone chip coating is held on by an adhesive layer that breaks down with age, UV exposure and weather. As it fails, chips wash into the gutters, leaving the steel underneath more exposed to corrosion.
Can I replace my decramastic roof with long-run steel?
Yes, and it is one of the most common re-roofing jobs in West Auckland. We remove the old tiles, check the battens and framing, and install a new steel roof. Building consent may be required depending on the project.
Can decramastic tiles be painted?
They can, as part of a restoration, provided the tiles are still sound. The roof must be cleaned, repaired and treated for rust first, and the right primer and coating used. Painting will not fix tiles that have rusted through.
