What causes a roof to start leaking during heavy rain?

Roof leaks during heavy rain are usually caused by water tracking under roofing materials rather than a single visible hole. Common causes include porous concrete tiles, deteriorated roof coatings, failed flashings, rusting metal roofing, and ageing Decramastic roofs where the protective stone chip has worn away. In many Auckland homes, the leak you see inside is not where the water is entering the roof.

Not all leaking roofs need to be replaced. Some leaks can be repaired if the roof structure and materials are still in good condition. However, if a roof has multiple leaks, widespread deterioration, or ongoing issues, repairs often become short-term fixes. In these cases, a roof coating system can be a more cost-effective long-term solution compared to re-roofing.

Yes — in most cases, roof coating is significantly cheaper than re-roofing. Roof coatings waterproof the entire roof surface, sealing small cracks, porous areas, and weak points that cause recurring leaks. This approach can extend the life of an existing roof by 10–20+ years without the cost and disruption of a full replacement.

We offer same-day or next-day leak inspections across Auckland, weather permitting. Roof leaks should be assessed as soon as possible, especially during ongoing rain, as water damage can worsen quickly and lead to ceiling, insulation, or timber damage.

Roof leaks often return because the repair only addressed the visible problem, not the underlying cause. Water can travel beneath tiles, sheets, or membrane systems before entering the building. If the roof surface itself is deteriorating, spot repairs may delay the issue rather than resolve it. A full roof coating system addresses the entire roof, reducing the risk of future leaks.

Yes. Concrete tile roofs commonly become porous over time, allowing water to soak through the tiles during heavy rain. Even if tiles look intact, moisture can penetrate the surface and cause leaks underneath. Roof coatings are often used on concrete tile roofs to reseal the surface and prevent ongoing water ingress.

Yes. Metal roofs can leak due to failed fasteners, degraded flashings, thermal movement, or rust pinholes that are difficult to see from ground level. Leaks may only appear during heavy or wind-driven rain. In some cases, a membrane coating provides better long-term protection than repeated repairs.

Decramastic roofs can leak as the stone chip surface wears away, exposing the metal beneath to corrosion. Leaks often occur at laps, fixings, or rusted sections. Roof coating systems are commonly used to restore and waterproof Decramastic roofs, preventing further deterioration and leaks.

If a leaking roof is left untreated, water can damage ceilings, insulation, electrical systems, and timber framing. Over time, this can lead to mould growth and structural issues. Early inspection and repair — or coating where appropriate — can prevent costly internal damage.

No. We always assess the roof first. If a repair is appropriate and cost-effective, we’ll recommend that. If ongoing repairs are unlikely to solve the issue long-term, we’ll explain why a roof coating system may be the better option — so you can make an informed decision without pressure.

Yes. We provide leaking roof inspections and repairs across all Auckland areas, including North Shore, West Auckland, South Auckland, East Auckland, and surrounding suburbs.

A roof leak is considered urgent if water is actively entering the home, ceilings are sagging or staining, or leaks worsen during rainfall. In these situations, we recommend contacting us immediately to arrange an urgent inspection and prevent further damage.
