What is it?

What is roof restoration?

Roof restoration is not just painting and it's not just cleaning — it's a full repair and protection system. The process covers everything from inspection and tile-level repairs, through rebedding and repointing all failing mortar, to a complete prep-prime-seal-coat sequence that seals the roof against Sydney's conditions for the next decade-plus.

A properly executed restoration follows a fixed sequence: inspection → tile repairs → rebedding & repointing → surface prep → primer → sealer → UV-rated topcoat. Skip any step and the coating fails early.

Sydney homes specifically need UV-rated coating systems. Sydney's UV index regularly hits extreme levels, coastal salt air degrades unprotected coatings faster than inland climates, and summer heat cycles cause significant tile expansion and contraction. A UV-rated elastomeric coating is rated to flex with those cycles rather than crack.

Warning signs

Signs your roof needs restoration

Cracked or broken tiles

Water enters the roof cavity long before ceiling stains appear. Each crack is a direct path in.

Crumbling mortar in gutters

Chunks of grey mortar washing into your gutters means ridge and hip pointing has failed.

Moss and lichen growth

Holds moisture against tiles around the clock, accelerating cracking and degradation.

Faded or flaking coating

UV protection is exhausted. Tiles are now absorbing UV damage directly — the window to restore without replacing is closing.

Water stains on interior ceilings

Damage is already happening inside the roof cavity. The longer it continues, the more the repair bill grows.

15+ years since last restoration

Overdue regardless of appearance. Coating, mortar, and tile condition all degrade on a 10–15 year cycle in Sydney's climate.

Step by step

The restoration process

1

Free inspection

Full roof access, photos, moisture and wear assessment. Written scope delivered before any commitment — you know exactly what's needed and what it costs.

2

Tile repairs

Crack filling, broken tile replacement, flashing checks. Fix what's failed so coatings aren't applied over active problems.

3

Rebedding & repointing

All ridge, hip and valley mortar reset and pointed. This is structural — done before any surface work begins.

4

Prep & clean

Surface preparation for coating adhesion. Low-pressure soft wash with biocide where needed — removes moss, lichen, and contamination without damaging tiles.

5

Sealer & primer

Compatible base system for the topcoat. The primer and sealer bond to tile and create the adhesion layer the final coat needs to last.

6

UV-rated topcoat

Manufacturer-backed coating in your chosen colour. Progress photos throughout every stage — you see what was found, what was fixed, and how it was coated.

Pricing

How much does roof restoration cost in Sydney?

Roof Clean & Treat

Moss, lichen & algae removal. Low-pressure soft wash with biocide.

From $490

ex GST

Repairs & Repointing

Broken tiles, ridge & hip repointing, leak fixes.

From $1,490

ex GST

Full Roof Restoration

Inspection, repairs, rebedding, repointing, primer, sealer & UV coating.

From $2,490

ex GST

Final price depends on roof size (measured in squares), pitch and access difficulty, the number of broken tiles needing replacement, the extent of repointing required across ridges and hips, and the coating brand selected. Two roofs of the same physical size can cost very different amounts once what's on them is assessed. That's why every Pristine quote is confirmed on-site after a free inspection — never sight-unseen.

Restoration vs replacement

Which one do you actually need?

Restoration

$3k–$15k

Right when tiles are structurally sound. Coating, mortar, and surface have degraded but the tiles themselves are intact. Adds 10–15 years of service life.

Replacement

$20k–$50k+

Only needed when tiles are cracked through, broken beyond individual repair, or the substrate underneath has structurally failed.

Most Sydney roofs that look tired need restoration, not replacement. A free inspection tells you which category yours is in — no obligation.

Hiring guide

What to look for in a Sydney roof company

Written scope before work starts

Not a verbal estimate that changes on the day. Every Pristine job is scoped in writing before a tile is touched.

$10M+ public liability

Pristine carries $20M. Documentation available on request before any job starts.

Owner on every job

Not rotating subcontractors. The same face on the website is the same face on your roof.

Low-pressure soft wash on tiles

High pressure damages terracotta and concrete tiles. Method must match the surface.

Manufacturer-backed UV-rated coatings

Coatings rated for Australian UV conditions — not imported products that degrade faster under Sydney's sun.

Progress photos during the job

Full transparency on what was found, what was fixed, and how it was coated.

FAQs

Common questions answered.

Full roof restoration starts from $2,490 ex GST — covering inspection, tile repairs, rebedding, repointing, primer, sealer, and UV-rated coating. Repairs and repointing only start from $1,490. A clean and biocide treatment starts from $490. Final price confirmed on-site after a free inspection. Factors that affect price: roof size in squares, pitch, number of broken tiles, extent of repointing, coating brand.
Typically 2–5 days depending on roof size, extent of repairs, and drying time between coats. Smaller roofs with minimal repairs can be done in 2 days. Larger roofs with significant repointing and multiple coating passes take longer. Timeline is confirmed in your written scope before any work begins.
Restoration ($3k–$15k) repairs and recoats existing tiles to extend life by 10–15 years — right when tiles are structurally sound but the coating, mortar, and surface have degraded. Replacement ($20k–$50k+) removes and relays all tiles — only when the substrate has failed beyond repair. Most Sydney roofs that look tired need restoration, not replacement. A free inspection tells you which category yours is in.
If your mortar is crumbling, tiles are cracked, or you have an active leak, you need more than a clean. Those issues require repairs and repointing before any coating is applied — applying coating over failing mortar or cracked tiles is a waste of money. A free inspection tells you exactly what's needed with no upsell.
High-pressure washing can damage terracotta and concrete roof tiles — it erodes the tile surface, strips granules, and drives water under flashing. Pristine uses low-pressure soft wash with biocide treatment. The method is always matched to the surface. No blasting where it isn't appropriate.
A UV-rated elastomeric coating applied over a compatible primer and sealer system is the industry standard for Sydney's conditions. The elastomeric formulation flexes with thermal expansion rather than cracking. Pristine uses manufacturer-backed coatings rated for Sydney's UV intensity, humidity, and coastal salt air — not imported products that degrade faster under Australian conditions.
Look for crumbling or cracked mortar on ridges and hips, loose ridge tiles you can move by hand, small pieces of grey mortar appearing in your gutters, or water entry after heavy rain. Failed pointing lets water, pests, and structural movement into your roof frame — it needs to be fixed before any coating is applied. A free inspection confirms the extent.
Yes. Moss and lichen hold moisture against tile surfaces continuously, accelerating degradation and cracking over time. Lichen physically bonds to the tile surface and damages the glaze as it grows. They also signal neglect to buyers and valuers. A biocide treatment removes them and stops regrowth — from $490, it's one of the cheapest problems you can fix on a roof before it compounds.
Yes. Pristine Pressure Clean holds $20M public liability insurance — double the industry minimum of $10M. The crew is height-trained with full PPE. Documentation is provided on request before any job starts. You get the certificate, not a verbal assurance.
