Your tile roof looks tired but the structure is sound. Restoration can add 15–20 years of life at a fraction of replacement cost. Here's how it works.
Tile roof restoration is a comprehensive process that returns an ageing tile roof to near-new condition without full replacement. It typically includes:
• High-pressure cleaning to remove moss, lichen, dirt, and salt deposits • Replacement of broken or cracked tiles • Rebedding and repointing of ridge capping • Valley and flashing inspection and repair • Application of a sealer coat and two coats of roof membrane/paint
The result is a roof that looks new, is fully waterproofed, and has an extended lifespan of 15–20 years beyond the restoration.
Restoration is suitable for concrete tile roofs (the most common type on the Central Coast) and terracotta tile roofs where the tiles themselves are structurally sound but have lost their surface coating and aesthetic appeal.
The decision depends on the structural condition of your tiles and timber framing:
**Restore when:** • Tiles are structurally sound (not crumbling or delaminating) • Timber framing is in good condition (no rot, no sagging) • Less than 5% of tiles are broken or missing • The roof is 20–40 years old • You want to maintain the existing tile look • Budget is a consideration (restoration costs 30–50% of replacement)
**Replace when:** • Tiles are crumbling, delaminating, or absorbing water • Timber framing shows rot, termite damage, or structural deflection • More than 10% of tiles are damaged • The roof is 50+ years old • You want to change from tile to metal (lighter, more durable) • Sarking (underlay) is missing or degraded and cannot be retrofitted
**The test:** Pick up a tile and tap it. A solid ring means the tile is sound. A dull thud or crumbling edges means the tile has reached end of life and restoration will not provide lasting results.
We inspect before quoting and will honestly advise if restoration is not appropriate for your roof.
A professional tile roof restoration follows this sequence over 3–5 days:
**Day 1: Preparation** • Roof inspection and broken tile identification • Gutter protection installed • High-pressure cleaning (2,500–3,500 PSI) to remove all biological growth and surface contamination • Roof left to dry (minimum 24 hours)
**Day 2: Repairs** • Broken tiles replaced with matching profiles • Ridge capping rebedded and repointed where required • Valley irons inspected and repaired/replaced if corroded • Flashings checked and re-sealed • Any pointing or sealing around penetrations (vents, aerials)
**Day 3–4: Coating** • Primer/sealer coat applied (penetrates tile surface, provides adhesion) • First coat of roof membrane applied (typically acrylic-based) • Second coat applied (provides UV protection, colour, and waterproofing)
**Day 5: Final inspection** • Touch-ups and edge detailing • Gutter clean-out • Final inspection and handover
Weather dependent — we require 3+ consecutive dry days for the coating phase. We monitor forecasts and schedule accordingly.
Restoration pricing depends on roof size, condition, and access:
**Typical costs (Central Coast/Sydney/Newcastle):** • Small home (100–150m² roof area): $4,500–$7,000 • Average home (150–250m² roof area): $7,000–$12,000 • Large home (250–400m² roof area): $12,000–$18,000
**What's included in a quality restoration:** • Full high-pressure clean • Up to 10 tile replacements (additional tiles charged per unit) • Ridge capping repointing (rebedding additional if required) • Valley and flashing inspection • Primer + 2 coats of premium roof membrane • 10-year coating warranty
**Compare to full replacement:** • Tile-to-tile replacement: $15,000–$30,000+ • Tile-to-Colorbond conversion: $20,000–$45,000+
Restoration delivers 70–80% of the benefit at 30–50% of the cost of replacement. For structurally sound roofs, it is the most cost-effective option.
A quality restoration using premium coatings adds 15–20 years to your roof's functional life. Factors that affect longevity:
**Positive factors:** • Premium coating products (Dulux, Shieldcoat, Roof Protect) with 10–15 year warranties • Thorough surface preparation (the most critical step) • Proper repairs completed before coating • Good roof ventilation reducing heat stress on coatings
**Negative factors:** • Coastal salt exposure (reduces coating life by 3–5 years) • Heavy tree coverage (biological growth accelerates coating breakdown) • North-facing aspects (maximum UV exposure) • Poor preparation (coating over moss or loose material fails within 2–3 years)
We use premium Australian-made roof coatings with manufacturer warranties. Combined with our workmanship warranty, you have confidence the restoration will perform for its full expected lifespan.
After restoration, we recommend a simple annual check: look for any areas where coating appears to be lifting or biological growth is returning. Catching these early means a simple touch-up rather than a full re-coat.
Typically 3–5 working days depending on roof size and weather. The process requires at least 3 consecutive dry days for the coating phase. We schedule around weather forecasts to ensure quality results.
Yes. Roof restoration coatings are available in a wide range of colours. Many homeowners take the opportunity to update from dated colours (brown, green) to modern tones (charcoal, slate grey, surfmist). Colour change does not affect cost.
Restoration addresses surface waterproofing and common leak points (ridge capping, valleys, flashings). However, if leaks are caused by structural issues (cracked tiles, failed sarking, timber movement), these must be repaired separately. We identify all issues during inspection and include necessary repairs in the quote.
It depends on tile condition. If tiles are structurally sound (not crumbling or water-logged), restoration at 40 years can extend life to 55–60 years. If tiles are deteriorating, replacement is the better investment. We'll give you an honest assessment.
