Before the colour goes on, we deal with the reasons a roof fails — perished ridge bedding, broken tiles, rust, moss and porous surfaces. Restoration first, then the coating, with a written scope before work begins.

What Roof Painting Includes

Roof Painting Melbourne for Tile, Colorbond & Cement Sheet

Our roof work covers the full surface and the parts that decide whether it lasts — concrete and terracotta tile, Colorbond and metal sheeting, and cement sheet, through to the ridge caps, valleys and flashings where most leaks begin. The path is set by condition, not age: a sound roof is cleaned, primed and recoated; a tired one is restored first — ridges re-bedded and re-pointed, broken tiles replaced, rust treated — before any colour goes on.

Porous concrete tile is sealed before finish coats; glazed terracotta is assessed first, because coatings do not bond to a sound glaze. What the substrate check finds is written into your scope before work begins, so you know which path your roof needs and why.

Our Roof Painting Process

Our Preparation-Led
Roof Restoration Process

A roof finish is decided long before the colour coat. The work moves through a deliberate sequence — each stage given its full time, without exception. You will have a single point of contact from consultation through to completion, with clear updates at each stage of the project.

Request a Roof Assessment
High-pressure cleaning & protection

Surrounds, gutters and downpipes managed and run-off controlled. The roof high-pressure cleaned to strip moss, lichen and the chalky degraded layer back to sound material before any coat is applied.

01
Consultation & Brief

A senior Mousi team member assesses the roof, identifies the substrate and condition, and discusses the brief in full. Colour consultation is included. A fully itemised written proposal follows.

02
Substrate Assessment

The roof is read for perished ridge bedding, cracked or slipped tiles, rust on metal, corroded valleys and porous or chalking surfaces — the failures that decide a coating’s life. The scope of correction, and whether the roof needs restoration or recoating, is set before any work begins.

03
Cleaning & Protection

Gutters, surrounds and downpipes managed, run-off controlled, then the roof high-pressure cleaned to strip moss, lichen, dirt and the chalky degraded layer — so the coating bonds to sound material, not loose debris.

04
Restoration & Repair

Ridge caps re-bedded and re-pointed, broken and slipped tiles replaced, rust treated or corroded sheets and fixings renewed, perished valleys replaced — the work that addresses the cause of leaks and early failure, most often skipped.

05
Seal, Prime & Coat

Porous tile sealed and primed, metal primed to the substrate, then the specified roof coating built up in the coats the system calls for — for an even, protective finish across the whole roof. Projects are managed by Mousi with specialist support where required, while Mousi remains responsible for scope, preparation standards and finish quality.

06
Final Review & Property Passport™

A final check of the roof against the written scope. On completion, a Property Passport™ records the substrate, system and colour applied, so future touch-ups are matched precisely. Access cleared, gutters left clean, the property left orderly.

On The Roof

What restoration
actually looks like.

The detail behind a roof finish is hard to picture from the ground. This is the work up close — the cleaning, the repairs and the coating, on the roof where it happens.

Restoring the Roof Surface

Common roof defects
& restoration.

Before any coating goes on, the underlying defects have to be identified and corrected. A coat over a compromised roof hides the problem briefly and then fails with it — often as a leak. We assess the roof for the issues below and restore the cause before any coating is considered, so the result is sound, not just newly coloured.

Perished Ridge Bedding & Pointing

Cracked mortar bedding and pointing under the ridge caps — the most common entry point for roof leaks. We remove and re-lay the bedding, then re-point with a flexible compound, so the ridge line is sound before any coating goes on.

Cracked, Slipped & Broken Tiles

Cracked, slipped or delaminating terracotta and concrete tiles let water through and undermine the coating. We replace broken and slipped tiles before coating rather than painting over them, so the surface is whole.

Rust & Corrosion on Metal

Surface rust at fixings, sheets and laps on Colorbond and metal roofs. We treat the rust or replace corroded sheets and fixings, then prime to the substrate — so corrosion is not sealed in to spread under the new topcoat.

Moss, Lichen & Algae

Moss and lichen hold moisture against the surface and lift the degraded layer. We high-pressure clean the roof back to sound material and treat the growth, so the coating bonds to the tile or sheet rather than to a living layer that will let go.

Corroded & Perished Valleys

Valley irons — where two roof planes meet and water concentrates — rust and perish over time and become a leak path. Where they have failed, we renew the valleys before coating so the roof sheds water as it should.

Porous & Chalking Surfaces

Weathered concrete tile becomes porous and chalky as its original surface breaks down. We clean it back, then seal and prime, giving the topcoats a stable base to bond to rather than soaking in and lifting.

Specification & standards.

The decisions made before the colour coat — the systems, sheens and preparation specified for your roof. Sealers, primers and finish coats are specified according to the substrate, its condition, the roof’s exposure and manufacturer requirements.

Coating Systems

Sealer, primer and finish coats specified for each roof type — seal-and-prime systems for porous concrete tile, metal-appropriate primer and topcoat for Colorbond and metal, and the membrane or roof coating the surface and condition call for.

Colour & Finish

Roof colour sets the look of the home from the street and affects heat; the finish governs how the surface sheds water and holds through Melbourne’s seasons. We specify both together and record them, rather than defaulting to one product.

Exposure-Matched Specification

North and west-facing roof planes and exposed, coastal frontages weather faster, so they are specified accordingly — with ridges, valleys and penetrations sealed against the points where water concentrates and enters.

Ridge, Valley & Penetrations

The detail decides whether a roof leaks. Ridge caps are re-bedded and re-pointed, valleys renewed where perished, and flashings around penetrations checked — the parts a colour coat alone never addresses.

Preparation Standards

A fixed sequence: assess the roof, high-pressure clean to sound material, re-bed and re-point ridges, replace broken tiles, treat rust, renew valleys, seal and prime, then coat. The steps most often skipped — thorough cleaning and back-to-sound restoration — we never skip.

Older Roofs & Hazardous Materials

Some older Melbourne roofs — particularly cement sheet — may contain asbestos-containing materials, and older roof coatings may contain lead. Where these materials are suspected, appropriate testing and specialist assessment may be recommended before cleaning or coating works commence. Safety, compliance and long-term performance remain the priority throughout the project.

Tile, Colorbond & Cement Sheet

Each roof type asks for
a different system.

Concrete and terracotta tile, Colorbond and metal, and cement sheet each fail differently and each asks for a different build. Porous concrete tile is sealed and primed before colour coats; glazed terracotta is assessed first, because coatings do not bond to a sound glaze; metal is cleaned, has its rust treated and is primed to the substrate; cement sheet is checked for condition and sealed for porosity. We specify to the roof rather than defaulting to one product.

Whichever the type, the roof is cleaned, restored where needed and primed to the correct system before the colour goes on — ridges, valleys and penetrations given the attention that decides whether a roof holds. The aim is a finish that sheds water and weathers evenly, not one that looks new for a season and fails at the detail.

Roof Restoration in Practice

What restoration
actually looks like
on the roof.

The sequence is explained above. This is what it looks like on the roof — the cleaning, ridge work, repair and priming that decides the finish long before the colour coat.

Most of it is invisible from the street once we leave. All of it is the reason the roof holds.

Roof Painting & Restoration — Charcoal Roof Membrane Finish

A complex tiled roof with multiple hips, ridges, valleys and lower roof sections, shown with a refined charcoal roof membrane finish. This visual example demonstrates how a weathered tiled roof can be transformed through careful cleaning, preparation, sealing and spray application.

Roof type
Multi-plane tiled roof with hips, ridges, valleys and lower roof sections. The profile requires careful surface preparation, edge detailing and consistent spray application across all visible planes.
Condition found
Typical Melbourne roof ageing — faded tile colour, surface chalking, general grime build-up, uneven tone and visible weathering across the tiled surface. The roof would require a thorough clean and preparation process before coating.
Work completed
Preparation, sealing and spray coating. High-pressure cleaning to remove dirt, moss, lichen and loose contamination, followed by preparation of ridge caps, hips, valleys, gutters and roof edges. The roof is then sealed and spray-coated to create a consistent charcoal finish, with attention to clean lines, even colour and sharp detailing around ridges, valleys and edges.
Coating system
Exterior roof membrane coating system. A specified roof membrane system including surface preparation, suitable roof sealer/primer and two finish coats of exterior-grade roof membrane coating, selected to improve colour consistency, weather resistance and long-term durability while retaining the natural profile of the tiled roof.
Colour
Colourbond-style Monument / charcoal grey — a deep contemporary finish that gives the home a sharper architectural appearance while complementing the light exterior façade and landscaped surrounds.

Restoration or Recoating?

Where the difference is
built in.

The path your roof needs is decided by condition, not by guesswork — and the difference between the three approaches below is rarely visible on the first day. It shows in what was done beneath the colour, and whether the roof still sheds water in the seasons after. Our aim is not simply to apply more coating. It is to reduce the likelihood of premature failure and leaks by restoring the roof before any colour goes on.

A finish, recorded
and protected.

A restored roof deserves a record. Qualifying projects include a Property Passport™ — a permanent record of the substrate found, the repairs carried out, and the coating system, colour and product applied to your roof, so future touch-ups and maintenance can be matched precisely rather than guessed.

Ongoing care is available for eligible projects through Mousi Care™ — a scheduled check on the roof’s condition over time, so wear at the ridges, valleys and surface is caught early rather than after the next leak.

Common Questions

Roof painting
answered directly.

Everything you need to know before your first roof assessment. If your question isn’t here, we’re happy to discuss it directly.

Request a Roof Assessment

Coating on its own is not a waterproofing guarantee. Most roof leaks come from cracked ridge bedding, perished pointing, slipped or broken tiles, or corroded valleys. Those causes are addressed in the restoration stage — re-bedding and re-pointing ridge caps, replacing broken tiles, and renewing valleys — before any coating goes on. The roof is checked first so the cause is identified, not simply covered over.

Recoating cleans a sound roof and applies primer and colour coats. Restoration is the repair work done first when the roof is not yet sound — high-pressure cleaning, re-bedding and re-pointing ridge caps, replacing broken tiles, treating rust on metal, and renewing valleys. Which path applies is decided by the condition found at the check, and that finding is written into your scope before any coating is quoted.

Glazed terracotta is non-porous, and coatings do not bond reliably to a sound glaze, so we do not coat sound glazed terracotta. Unglazed or weathered terracotta can be sealed and coated once it has been cleaned and primed. The tile is assessed before any work is quoted, and the finding is recorded in the written scope so you know what was found and why.

Yes. Metal roofs are cleaned, rust is treated or corroded sheets and fixings replaced, and a metal-appropriate primer and topcoat system is applied. Recoating restores colour and surface protection to a sound metal roof; where corrosion is present it is dealt with before any coating, so it is not sealed in under the topcoat.

Service life depends on the substrate, the condition at the time of work, the coating system specified, and the roof’s exposure. The system used and the surface condition found are recorded, and product manufacturer warranties are documented where they apply to qualifying projects. An honest figure can only be given once the roof has been assessed, not before.

A roof with sound tiles and structure that has lost only its surface finish is usually a restoration candidate. Widespread cracked or delaminating tiles, failed battens, or structural movement point toward replacement instead. The substrate check identifies which, and that finding is given to you in writing before any commitment is made.

Restoration is the preparation that makes a roof sound before colour goes on: high-pressure cleaning to strip moss, lichen and the chalky degraded layer; re-bedding and re-pointing ridge caps; replacing broken or slipped tiles; treating rust or replacing corroded sheets on metal roofs; renewing perished valleys; and sealing and priming porous tile. Each step removes a specific cause of early coating failure or water entry.

Cement sheet roofs are cleaned and assessed for condition and stability, sealed to manage their porosity, then coated. Older sheeting is checked and handled with appropriate care before work proceeds. Where a material is suspected of containing asbestos, appropriate testing and specialist assessment may be recommended before any preparation begins.

Qualifying roof projects include Property Passport™ documentation — a record of the substrate found, the repairs carried out, the coating system applied, and the colour and finish used, so future work can be matched precisely. Mousi Care™ is available for eligible projects: a scheduled check on the roof’s condition over time, so wear is caught early rather than after the next leak.
