Roof Water Entry Investigation & Repairs

Signs that further investigation may be required

• Ceiling staining, peeling paint or damp insulation.
• Water appearing during wind-driven rain.
• Blocked, overflowing or poorly graded gutters.
• Corroded flashings, open laps or failed penetrations.
• Condensation or dripping beneath single-skin roof sheeting.

What DAC checks

• Roof sheets, tiles, ridges, valleys, flashings and penetrations.
• Gutters, sumps, outlets, downpipes and discharge points.
• Controlled spray and isolation testing where safe and suitable.
• Roof-space moisture mapping, thermal imaging and direct readings.
• Ventilation, insulation and condensation conditions.

Repair and remediation direction

Repairs may include flashing replacement, penetration sealing, gutter or downpipe works, tile or sheet replacement, drainage correction, ventilation improvements and localised internal drying.

Widespread deterioration or unsafe roof access may require specialist roofing or engineering input.
