Factors That Extend Timeline

Weather Delays

• Rain: Work cannot proceed in wet conditions (minimum 1-3 day delay per event)

Unexpected Issues

• Structural damage: Add 2-5 days for repairs
• Termite damage: Add 3-7 days for treatment and repairs
• Asbestos discovery: Add 5-10 days for licensed removal
• Water damage: Add 2-4 days for drying and repairs

Seasonal Considerations for Sydney

Best Times for Roof Replacement

• Spring (Sept-Nov): Ideal conditions, moderate contractor availability
• Autumn (March-May): Excellent weather, plan before winter
• Summer (Dec-Feb): Dry conditions but extreme heat, Christmas holidays affect availability
• Winter (June-Aug): Higher rain risk, longer timelines, better contractor availability

Project Management Tips

• Book 4-8 weeks in advance during peak seasons
• Ensure clear access for trucks and equipment
• Arrange alternative parking if driveway blocked
• Notify neighbors of potential noise and disruption
• Plan to be away during noisiest phases if possible
• Document progress with photos for your records
