Roof Surveys: Why They're Essential for South London Properties

Roof problems are among the costliest property defects. Our experienced chartered surveyors explain what a comprehensive roof survey involves, why it's crucial for properties across South East London, and how early detection can save thousands in repair costs. This guide covers everything homeowners and buyers need to know about roof surveys in Greenwich, Lewisham, and throughout South London.

What is a Roof Survey?

A roof survey is a detailed inspection of your property's roof structure, covering, and associated elements. Our building surveyors conduct roof surveys as part of RICS Level 2 and Level 3 building surveys, or as standalone specialist inspections for properties throughout South East London.

During roof surveys, our chartered surveyors examine:

• Roof coverings (tiles, slates, flat roof materials)
• Roof structure and timbers
• Flashings around chimneys and abutments
• Gutters and downpipes
• Chimney stacks and pots
• Valley gutters and roof junctions
• Ridge tiles and verges
• Roof ventilation and insulation access

Common Roof Problems in South London

Our surveyors regularly identify these issues during roof surveys across Greenwich and Lewisham:

Slipped or Missing Tiles/Slates

Wind, weathering, and age cause roof covering failures. Victorian properties in South East London often have original slate roofs over 100 years old, nearing the end of their lifespan. Individual tile replacement costs £100-200, but widespread failure requires complete re-roofing (£8,000-£15,000).

Failed Roof Felt

Deteriorated roofing felt (underlay) allows water penetration even when tiles appear intact. Our building surveyors can only assess felt condition from loft spaces, making loft access crucial during property surveys. Felt replacement requires removing and replacing all roof coverings.

Damaged Flashing

Lead flashings around chimneys, skylights, and where roofs meet walls deteriorate over time. Failed flashings cause water ingress and internal damp. Replacement costs £500-2,000 depending on complexity and accessibility across South London properties.

Gutter and Downpipe Issues

Blocked, damaged, or inadequate guttering causes water overflow, leading to penetrating damp and potential structural damage. Our chartered surveyors check gutter capacity, condition, and proper water discharge during roof surveys throughout South East London. Gutter replacement costs £400-1,500 for typical South London terraced houses.

Types of Roof Survey

Level 2 Survey Roof Inspection

During RICS Level 2 home surveys, our surveyors inspect roofs using binoculars from ground level and adjoining properties. We assess overall condition, identify visible defects, and note areas requiring closer inspection. This provides good overview for conventional properties in reasonable condition.

Level 3 Survey Roof Inspection

RICS Level 3 building surveys include more detailed roof assessment. Our experienced surveyors access roofs where safely possible (using ladders or scaffolding), providing close-up inspection of coverings, flashings, and structural elements. Essential for older properties across Greenwich and South East London.

Specialist Roof Survey

Standalone roof surveys by our chartered surveyors include full access inspection, detailed condition report, repair recommendations, and cost estimates. Ideal when specific roof concerns exist or before purchasing properties with known roof issues across South London.
