When Restoration Makes Sense

A roof restoration involves cleaning, repairing, and recoating your existing roof. It's the right choice when:

• Your roof is 15-25 years old but structurally sound
• You have minor issues like cracked tiles, faded colour, or small leaks
• The roof frame and battens are in good condition
• You want to improve energy efficiency (reflective coatings can reduce cooling costs)
• Your budget is limited

What's Included in a Restoration

1. High-pressure cleaning
2. Rebedding and repointing ridge caps
3. Replacing broken tiles
4. Sealing valleys and flashings
5. Applying primer and two coats of roof membrane

When You Need a Full Replacement

Sometimes restoration isn't enough:

• Roof is 30+ years old with widespread deterioration
• Sagging or structural damage to the frame
• Significant water damage to the internal structure
• Asbestos roofing (common in homes built before 1990)
• You're doing a major renovation that changes the roofline

Material Options for Replacement

• Colorbond steel - Most popular in Australia, 30-50 year lifespan, lightweight
• Concrete tiles - Traditional, 50+ years, heavy (may need frame reinforcement)
• Terracotta tiles - Premium look, 50+ years, excellent thermal properties
• Metal deck - Commercial look trending in residential, very durable
