Buying a House: How a RICS Survey Rates Your Roofline's Condition

Updated 14 September 2026 · 5 min read

Unlike Scotland, where a Home Report is required before a property is even marketed, England has no equivalent mandatory pre-sale survey. Instead, a buyer typically commissions their own survey after an offer is accepted - and when they do, the roofline gets rated using a standardised RICS system worth understanding before you use the result to negotiate.

The condition rating system

RICS Home Surveys use a three-point scale for individual elements, including the roof covering, roof structure, and rainwater goods (gutters and downpipes):

• Condition Rating 1 - no repair currently needed
• Condition Rating 2 - defects that need repairing or replacing, but not considered severe
• Condition Rating 3 - serious defects needing urgent repair, replacement, or further investigation

Level 2 reports (HomeBuyer Reports) present this with a clear traffic-light colour system - green, amber, red - against each major element of the property, including the roofline specifically.

Level 2 vs Level 3

A Level 2 survey suits a conventional property in reasonable condition, and is the more common choice for a fairly standard house purchase. A Level 3 Building Survey is a considerably more detailed structural investigation, more appropriate for older properties, homes that have been significantly altered, or anywhere a Level 2 report (or your own viewing) has already flagged something worth investigating further - a roof in visibly poor condition being a classic trigger for stepping up to Level 3.

What commonly triggers a Rating 2 or 3 on the roofline specifically

• Visible sagging, missing or slipped tiles, or damaged flashing (roof covering and structure)
• Guttering that’s clearly blocked, damaged, poorly supported or leaking (rainwater goods)
• Damp staining the surveyor can trace to roofline defects rather than another cause

Using the rating in a negotiation

A Condition Rating 3 finding gives you a concrete, documented basis to renegotiate price, ask the seller to complete repairs before completion, or in some cases walk away - far stronger footing than a general impression that “the roof looked a bit tired.” Getting an independent quote for the actual repair cost (see our North West cost guide) turns a vague survey finding into a specific number to negotiate against.

If you’re selling

Addressing an obvious roofline issue before a buyer’s survey flags it is often cheaper than the price reduction a Rating 3 finding tends to trigger during negotiation - worth considering if you know your fascia or guttering is visibly in poor condition before you list.
