Building guide

Roof space (attic) inspection guide

The roof void reveals leaks, insulation issues, framing condition, and pest activity that ceilings can hide for years.

Roof space

Why it matters

Water entry, failed sarking, and timber damage often show first in the roof space. A careful inspection here protects you from surprises after the first heavy rain.

Common defects

Rated the way we discuss findings in reports — Major, Minor, Safety, or Further investigation.

Water staining and active or historic leaks

Major

What you may see: Dark stains on rafters, sarking, or ceiling backs; damp insulation.

Risk: Ongoing water damage, mould, and ceiling failure.

Damaged, missing, or poorly detailed sarking

Major

What you may see: Torn membranes, gaps at ridges or penetrations.

Risk: Wind-driven rain and condensation issues.

Decayed or damaged roof framing members

Major

What you may see: Soft timber, splits, insect workings, or previous poor repairs.

Risk: Reduced structural reliability of the roof.

Inadequate or disturbed insulation

Minor

What you may see: Thin, missing, or compressed batts; gaps at edges.

Risk: Higher energy costs and uneven comfort.

Visible electrical or safety concerns in the void

Safety

What you may see: Exposed junctions, unsafe boarding, restricted safe access.

Risk: Fire or fall hazard — often needs specialist follow-up.

Evidence of pests in roof framing or debris

Further investigation

What you may see: Mud tubes, frass, nesting material, or damaged timber.

Risk: May indicate timber pest activity requiring pest inspection focus.

Quality checklist

What “good” tends to look like for this area.

  • Dry framing and ceiling backs with no active leak signs
  • Intact sarking or appropriate underlay for the roof type
  • Reasonable insulation coverage
  • Safe access path where a void exists
  • No obvious pest harbour or active workings

How Sitescop inspects

  1. Access via manhole where present and safe
  2. Survey for staining, moisture, framing condition, and penetrations
  3. Review insulation and ventilation clues
  4. Photograph defects and typical views for the report
  5. Recommend roof exterior correlation when leaks are suspected

Technology & knowledge

  • Moisture clues correlated with thermal imaging on combined assessments where used
  • Detailed photography in low light
  • Clear reporting of access limits

FAQ

Every house has a roof space?

No. Some roofs are flat or have minimal voids. We inspect what is readily accessible and state limitations.
