Roofing Adelaide: All Roof Repair Services

Cracked cement mortar on ridge and hip capping is the most common cause on any tiled roof built before the 2000s. Adelaide's hot summers expand the roof, winter rain soaks it, and reactive clay under the plains shifts the frame slightly, so rigid mortar cracks and water gets under the caps. After that come rusted valley irons, lifted or fatigued flashings around chimneys and penetrations, porous concrete tiles, torn or missing sarking, and gutters that have lost their fall and overflow back under the eaves. On metal roofs it is usually backed-out screws, rusted laps and sheets lifted by a northerly. The leak inside the ceiling is often a long way from the point where water gets in, which is why a proper inspection comes first.

Usually, yes. Most Adelaide roof leaks come down to one or two failed components: a ridge that needs rebedding, a valley that has rusted through, a flashing that has lifted, a handful of cracked tiles, or screws that have backed out. Each of those is a repair, not a replacement. Replacement only becomes the right answer when the roof covering itself has failed across the whole roof, such as concrete tiles porous through their full thickness, a discontinued tile profile that cannot be matched, sheets rusted through rather than surface-rusted, or rotted battens. The roofer inspects first, tells you which situation you are in, and puts the options in writing before anything starts.

A full restoration on a tiled roof starts with a high-pressure clean, then replacement of every broken or slipped tile, rebedding and repointing of the ridge and hip capping with fresh mortar and a flexible pointing compound, replacement of rusted valley irons and lifted flashings, treatment of moss and lichen, and finally a primer or sealer followed by two coats of a roof membrane. On a metal roof it means replacing rusted screws with new cyclone-rated screws, treating rust, sealing laps, then priming and coating. The order matters: the repairs come before the coating so that the finished roof is sound underneath, not just clean on top. Every one of those steps should appear as its own line on the quote.

When the roof covering itself has failed rather than a component of it. Signs include concrete tiles that have gone porous through their full thickness and crumble when handled, terracotta tiles fretting across the whole roof, a discontinued profile that cannot be matched so every repair uses mismatched tiles, metal sheets rusted through rather than surface-rusted, battens that have rotted under long-term leaks, sarking missing across the whole roof, and an asbestos cement roof at the end of its life. Another sign is repairs that keep coming back each winter in different places. The roofer inspects the whole roof, tells you which situation you are in, and puts both the repair option and the replacement option in writing where both are possible.

Yes. Building work, including roofing, is regulated by Consumer and Business Services (CBS). A roofing contractor must hold a Building Work Contractors Licence issued by CBS, and roof plumbing, which covers metal roof sheeting, gutters, downpipes, flashings and box gutters, is licensed plumbing work under the Plumbers, Gas Fitters and Electricians Act. You are entitled to ask for the licence number before any work starts, and you can check it yourself on the CBS public register. A licensed roofer will give the number without hesitation. The licence details of the roofing business servicing this site are published here as soon as they are confirmed. Unlicensed work can affect your insurance and leaves you without recourse if it fails.

Two kinds. Manufacturer warranties apply to the products used, such as Colorbond steel, tiles, membranes and pointing compounds, and they run on the manufacturer's terms. The roofer's own workmanship warranty covers how those products were installed, and it is stated in writing on the quote rather than promised on the phone. This site does not publish warranty periods because they vary by job and by product, and an invented figure would mislead you. What you should insist on is that the workmanship warranty, the products used and the scope of work all appear in writing before you approve the job, so that if a problem appears later there is no argument about what was agreed.
