Frequently Asked Questions
Q1: Why do roofs fail and need repair or replacement?
A: Roofs deteriorate over time due to age, weather, and poor detailing. Common causes include:
• Membrane breakdown from UV and heat exposure.
• Blocked or undersized drainage leading to ponding water.
• Poor detailing around penetrations, flashings, and joints.
• Ad hoc patching over years of repairs, creating weak points.
• Structural fatigue in timber or steel roof framing.
When these issues compound, repairs may no longer be viable — full replacement ensures long-term protection.
Q3: What does roof repair or replacement involve?
A: Works vary depending on roof type (concrete, metal, membrane, tiled) but typically include:
• Condition assessment & moisture testing.
• Targeted repairs (membrane patching, flashing upgrades, joint resealing).
• Full strip and replacement of roof sheeting/membranes where beyond life cycle.
• Improved drainage detailing (sumps, scuppers, overflows).
• Integration with adjacent façades, balconies, and services.
Atomic Projects ensures roofs are rebuilt as complete systems, not patched in isolation.
Q5: How much does roof repair or replacement cost?
A: Costs vary significantly by system:
• Minor patch repairs: $10k–$50k.
• Medium membrane or sheet roof replacement: $200k–$1m.
• Large-scale replacements on towers/estates: $1m–$5m+.
We provide transparent, itemised cost plans that outline repair vs. replacement pathways so committees can make informed decisions.
Q7: What warranties are provided?
A: All roofing systems are backed by:
• Manufacturer warranties (10–30+ years depending on system).
• Workmanship warranties on installation.
• DBP compliance packs where required.
• Certification of drainage and waterproofing performance.
This ensures peace of mind for owners, committees, and insurers.
Q2: What are the signs that roof repairs or replacement are required?
A: Warning signs include:
• Recurring leaks despite multiple patch repairs.
• Visible cracks, blisters, or bubbling in the roof membrane.
• Sagging or ponding water after rain.
• Corrosion of sheet metal roofing or flashings.
• Interior damage such as mould, stains, or plasterboard failure.
These symptoms often indicate systemic failure, not just isolated defects.
Q4: How long does roof repair or replacement take?
A: Timelines depend on size, height, and complexity:
• Small roof repairs: 1–3 weeks.
• Medium roof replacements: 1–3 months.
• Large-scale or high-rise roofing systems: 3–6+ months.
We stage works and install temporary weatherproofing to protect the building throughout the project.
Q6: What is the impact on residents and tenants?
A: Roof works are disruptive but manageable. Key impacts include:
• Noise from demolition and installation.Restricted roof access for building services (e.g., HVAC, antennae).
• Scaffold or crane use around the perimeter.
• Temporary leaks risk if roofs are left open — mitigated by staging and weatherproofing.
Atomic Projects provides advance notices, live progress reporting, and clear communication to minimise inconvenience.
