Roof Survey vs HomeBuyers Survey: What's the Difference?

Summary

A HomeBuyers Survey provides a useful overview of the whole property, including a visual assessment of the roof. A specialist roof survey provides expert, detailed analysis of the roof only — to a depth that a general survey is not designed or intended to replicate. For most homebuyers purchasing older or complex properties, both surveys offer complementary value.

What Is a HomeBuyers Survey?

The RICS Level 2 HomeBuyers Survey is a standardised property inspection format. The surveyor visits the property and assesses its condition using a defined methodology, reporting findings against a traffic light system:

• Condition Rating 1: No repair currently needed
• Condition Rating 2: Defects that need repairing or monitoring but are not considered serious
• Condition Rating 3: Defects that are serious and/or require urgent attention

The survey covers the whole property — exterior, interior, services and grounds — and typically takes two to three hours to complete. It is designed to identify significant visible defects across all elements of the property.

How the HomeBuyers Survey Assesses the Roof

The RICS Level 2 survey assesses the roof externally, typically from ground level or from a vantage point accessible within the property boundary. The surveyor will assess:

• The visible condition of the roof covering
• The condition of visible flashings and gutters
• The condition of chimney stacks from ground level
• Whether the roof line appears level and regular

The loft space may be accessed if it is safely accessible, but this is not guaranteed. The survey does not include detailed assessment of individual tile fixings, flashing laps, valley details, ridge tile fixings or moisture levels within the construction.

What a Specialist Roof Survey Covers

A specialist roof survey dedicates the entire inspection to the roof. This includes:

• Assessment of every roof surface — pitch, flat, hip, valley, dormer
• Detailed inspection of all flashings and junctions
• Ridge and hip tile fixings assessment
• Valley construction and integrity
• Gutters, downpipes and drainage — falls, joints, condition
• Fascias, soffits — material condition and ventilation provision
• Chimney — masonry, pointing, flaunching, pot condition
• Loft space inspection — structure, timbers, insulation, ventilation, moisture
• Drone photography where direct access is not available
• Moisture meter readings as required

The report provides condition ratings for each element, photographic evidence, defect descriptions, prioritised recommendations and estimated repair costs.

A Direct Comparison

When Do You Need Both?

Commissioning both surveys makes most sense when:

• The property is more than 25 years old and the roof has not been recently replaced
• The RICS survey has flagged roof concerns or recommended specialist investigation
• The property has a complex roof form — multiple pitches, flat sections, extensive chimneys
• There is visible evidence of damage, missing tiles or water staining
• The property has recently had roofing work carried out and you want to verify its quality

Expert Commentary

"We regularly receive calls from buyers who have just received their RICS HomeBuyers Survey and been told that specialist investigation is recommended for the roof. This is exactly what the RICS surveyor should say — they have identified a concern and referred appropriately. The specialist survey then answers the question the general survey cannot. The two surveys complement each other; they are not alternatives."

Cost Comparison

A RICS Level 2 HomeBuyers Survey typically costs £400–£1,000 depending on property size and location. A specialist roof survey typically costs £250–£600. Commissioning both adds perhaps £300–£500 to the total survey cost — a modest addition to the due diligence spend on a purchase worth hundreds of thousands of pounds.

Frequently Asked Questions

Can the same person carry out both surveys?

A RICS surveyor with specialist roofing knowledge could, in principle, produce both reports. In practice, most RICS surveyors are generalists and refer specialist work to dedicated roof surveyors. A specialist roof surveyor does not typically produce RICS-format property surveys.

If the RICS survey says the roof is fine, do I still need a specialist survey?

A clean RICS assessment provides useful reassurance, but if the roof is old, complex or has any concern flagged — even a Condition Rating 2 — a specialist survey adds value. The RICS surveyor assesses the roof from a general property perspective; the specialist provides the depth of investigation the general survey is not designed to offer.

Can I use a specialist roof survey report with my mortgage lender?

A specialist roof survey is not a valuation report and cannot replace the lender's valuation. However, if a lender requests specialist investigation of a roofing concern flagged in a valuation report, our survey reports are suitable for this purpose.
