Roof Inspection & Building Survey Report

River Medway Aerials – Roof Inspection & Building Survey Report

Roof Inspection & Building Survey Report (visual only)

1. Property Information

2. Weather Conditions

Overcast, dry, light wind.

3. Roof Structure Assessment

• Roof Type: Pitched gable roof with interlocking concrete tiles (corrugated profile).
• Roof Covering Material: Concrete interlocking tiles; side extension with mineral felt flat roof.
• Condition of Tiles/Slates: General age-related wear; widespread biological growth (moss/lichen). No obvious missing tiles from altitude; local lifts possible where moss is present.
• Ridge / Hip Condition: Pronounced moss build-up along ridges/arrises; mortar condition not verifiable.
• Roofline (Fascia/Soffits): uPVC roofline components visible with organic staining at eaves.
• Underlay Condition: Not visible – visual drone survey only.
• Ventilation: Through‑tile vent/pipe penetration present on main slope; general ventilation not fully verifiable.

4. Building Survey Inspection (External Visual)

• Exterior Walls Condition: Brickwork appears serviceable; no significant cracks observed.
• Damp / Moisture Signs: No clear staining noted at eaves, but gutters show contamination suggesting possible overflow risk.
• Structural Movement Cracks: None observed.
• Windows & Doors: uPVC units observed; visual assessment only.
• Drainage / Gutters: Organic build‑up visible; cleaning recommended.

5. Defects Identified

1. Widespread moss & lichen on roof tiles
   • Severity: Medium
   • Urgency: Soon (3–6 months)
   • Recommended Action: Manual removal and biocide; avoid high-pressure washing; re‑inspection recommended.
2. Heavy moss accumulation at ridges/arrises and eaves
   • Severity: Medium
   • Urgency: Soon
   • Recommended Action: Remove moss, check ridge mortar, clean gutters post‑works.
3. Vent/pipe penetration – weathering at flashing/lead slate
   • Severity: Medium (potential leak point)
   • Urgency: Soon
   • Recommended Action: Close inspection from ladder; re‑dress lead/replace collar as needed.
4. Gutters – organic contamination and likely silt build-up
   • Severity: Medium
   • Urgency: Soon
   • Recommended Action: Full gutter/downpipe clean; consider guards.
5. Chimney – surface weathering; corroded cowl/brackets; redundant fixings
   • Severity: Medium
   • Urgency: Soon
   • Recommended Action: Remove redundant fixings; treat/replace metalwork; check flaunching/pot.
6. Flat roof (felt) – age-related wear
   • Severity: Low–Medium
   • Urgency: Routine
   • Recommended Action: Inspect laps/trims/upstands; monitor for cracking; plan maintenance cycle.

7. Summary & Recommendations

The roof appears generally serviceable for its age, with primary issues linked to moss/lichen build-up and contamination at eaves and ridges. No missing tiles identified from altitude; local lifting likely where moss is heavy. Chimney hardware shows corrosion; flashing points need closer inspection. Guttering requires cleaning post‑moss treatment.

Priority actions: (1) Professional moss removal + biocide, (2) Gutter/downpipe clearance, (3) Close inspection of flashings & chimney hardware, (4) Follow‑up inspection in 6–12 months.
