Our Roof Services

Roof Cleaning
Thorough removal of moss, lichen, algae, mould and organic staining using softwashing and controlled pressure cleaning. Our softwash treatment targets biological growth at its source, including spores and root systems that would otherwise grow back with water pressure cleaning alone. This includes terracotta, concrete and metal roofs such as colourbond.
Roof cleaning stands as its own service — not every roof needs a full restoration, and plenty of customers book a clean on its own to lift years of built-up grime, improve street appeal, or simply keep on top of maintenance.Cleaning process includes:
• Full inspection of tile & ridge condition and roof access before starting
• Softwash treatment to eliminate moss, lichen, algae and mould at the root
• Controlled pressure cleaning matched to tile type
• Gutter and downpipe check as part of the service
Roof Restoration
Concrete and terracotta age differently, which is why they're treated differently. Concrete is porous and loses surface strength and colour over time; thermal cycling — the constant expansion and contraction between heat and cold — breaks it down faster, so left uncoated, concrete deteriorates faster than terracotta. Terracotta is fired clay — naturally weather-resistant and typically left uncoated for its full lifespan. We've worked on terracotta heritage roofs over 100 years old that are still structurally intact where they've been properly maintained.
Concrete tiles need restoration once worn — terracotta is a choice, not a requirement, though plenty of homeowners coat theirs anyway for a colour change or the added membrane protection.Roof Restoration process includes:
• Full roof cleaning including elimination of organic growth using softwash
• Tile repairs and/or replacement
• Ridge re-pointing
• Stabilising or high build primer
• Premium two-coat protective membrane using advanced systems like Dulux AcraTex and IRC, designed to last 15+ years
Neglect a roof and minor deterioration progresses to leaks, ceiling damage and eventually a costly re-roof. Maintaining and restoring a sound roof extends its service life and protects the building for years to come.

Why Roof Restoration?

Moss, lichen, and heavy environmental pollutants destroy roofs. Lichen roots eat through ridge pointing and pit concrete and terracotta surfaces, trapped moisture breaks down pointing and bedding mortar, and damp build-up literally rotting the roof.Ignoring roof decay leads directly to severe consequences:Internal Water Ingress: Moisture breaches worn tile glazing and degraded ridge capping, rotting roof timbers, ruining ceiling insulation, and causing internal structural damage.Accelerated Structural Failures: Trapped water expands and contracts through season shifts, cracking tiles and completely dislodging ridge caps.Financial Loss: Deferring standard maintenance turns simple restoration work into complete roof replacements, timber re-framing, ceiling repairs, and reduces property appraisal value.Klean Kingdom stops the damage cycle. We pressure-strip years of embedded build-up, replace cracked tiles and re-point ridge caps with modern flexible compound, and apply industrial-grade protective coatings.We don't just wash and paint roofs—we restore structural integrity, lock out the elements, and safeguard your property asset for decades.

FAQ?

Do you restore roofs on heritage or older period homes?
Yes. We specialise in terracotta tiles and aged concrete tiles that get brittle over decades — the clay work-hardens, concrete tiles lose surface strength, and mortar bedding crumbles. A basic high pressure clean on an old roof-that you'd use on a 10-year-old modern tile roof and you'll crack tiles or erode them and dislodge bedding that's been holding since the house was built. We inspect tile condition first — checking for cracks, spalling, and how the ridge capping mortar is holding — before deciding on cleaning agents to eliminate the organic growth and spores, pressure, technique, and whether repairs or re-pointing is needed before any coating goes on. Heritage roofs get restored properly, not just blasted and painted over, the horrors of a cheap job that often ends in a costly roof replacement.
What does a roof restoration actually cost in Sydney?
Anywhere from a few thousand dollars for a straightforward clean-and-coat on a small single-storey roof, up to well over ten thousand for a large double-storey roof needing extensive tile replacement, and re-pointing. Roof size, pitch, access difficulty, tile type, number of broken or cracked tiles, and the coating system all move the price. We quote on-site, not over the phone — a roof restoration quote given without inspecting the actual roof is a guess, and we don't work off guesses.
How long does a roof restoration actually last?
15+ years with a properly applied system — Dulux AcraTex or IRC roof membrane, high build primer underneath, two full coats. The coating brand gets the credit, but the primer and surface prep do the real work. Skip the primer, rush the prep, or apply a single thin coat, and you'll see the coating fail in 3-5 years regardless of what's in the tin. We don't cut that corner.
Does pressure washing crack or damage roof tiles?
Not when it's done correctly — and it's rarely the pressure washing itself that causes damage, it's incorrect technique. Too much pressure at close range on old, brittle terracotta will crack tiles. The wrong nozzle angle can lift or dislodge ridge capping. We adjust pressure, distance, and nozzle type to the specific tile — concrete tiles handle more pressure than aged terracotta, and we treat them differently rather than running one setting across the whole roof.
What's the real difference between a roof clean and a full restoration?
A roof clean isn't just cosmetic — our softwash treatment removes moss, lichen, algae, and mould at the root, including the spores and root systems that would otherwise regrow and continue eating into the tile surface and pointing. It stops the active damage a dirty roof causes. A full restoration goes further: re-pointing cracked mortar joints, replacing broken or cracked tiles, applying a high build primer to seal and stabilise the surface, then two coats of a protective membrane system — required for concrete tiles once worn, optional for terracotta. A clean removes what's attacking the roof. A restoration repairs the damage already done and protects the roof structurally for over a decade.
How long does a roof clean or restoration job actually take?
A roof clean alone is usually done in a day, depending on size and access. A full restoration takes longer — 2 to 5 days for most residential jobs. Size of the roof, number of tiles needing replacement, and ridge condition all affect it. Weather matters too — coating systems need dry conditions to cure properly, so a job can run longer if rain moves in mid-project. We don't rush a coat on before it's ready to go on.
Do you offer ongoing maintenance after the restoration's done?
Yes — and it matters, because a restored roof left unchecked for years will still develop the same problems eventually: gutters clog, downpipes block, small tile cracks go unnoticed until they're leaks. Our maintenance program covers gutter and downpipe cleaning and periodic roof checks, so small issues get caught and fixed before they turn into a ceiling leak or another full restoration years earlier than it should've needed one.
Which Sydney suburbs do you cover for roof restoration?
All of Greater Sydney — Southern Highlands, Upper North Shore, inner west, harbourside suburbs, and western Sydney. If you don't see your suburb mentioned anywhere on this site, get in touch anyway — we cover far more ground than any suburb list can show.
What roofing products and systems do you actually use?
Dulux AcraTex and IRC roof membrane for the coating system, Sika for structural repairs and sealants, Selleys for general sealing work. These are trade-grade systems, not retail hardware-store product — the difference shows up in how long the job actually lasts. We match the system to your roof's tile type and condition, not the other way around.
