My homebuyer survey says the roof is condition rating 3. What should I do?

What does condition rating 3 mean for a roof?

Condition rating 3 is the most serious of the three ratings in a RICS Home Survey, and it means the surveyor wants the roof dealt with or looked at properly before you buy. RICS describes it as defects that are serious, or that need repairing, replacing or investigating without delay, and says written quotations for repairs should be obtained before you are legally committed to the purchase.

• Rating 1: no repair is currently needed.
• Rating 2: defects that need repairing or replacing but are not serious or urgent.
• Rating 3: serious or urgent defects, where RICS warns that leaving them could risk serious safety issues or severe long-term damage to the property.
• NI: the element was not inspected.

Ratings are given element by element, so check whether the 3 sits against the roof coverings, the chimney stacks or the roof structure seen from the loft. Read the wording next to the rating too, because RICS says the report describes the condition of each element and includes advice about repairs.

How closely did the surveyor look at your roof?

Usually from the ground, through binoculars and from inside the loft. The RICS descriptions of Level 2 and Level 3 surveys say the surveyor may inspect from ground level or neighbouring public property, and only uses a ladder for flat roofs and hatches no more than 3m above the ground or floor. They enter the roof space if it is safe and reasonable to do so, but they do not move insulation or stored goods, and the inside of the chimney is not assessed.

That matters in Yorkshire, where the rear slope of a Victorian terrace or the valleys of a stone slate farmhouse roof are often hidden from the street. RICS says that where a surveyor cannot reach a conclusion with reasonable confidence, they should recommend further investigation. So a 3 is often a prompt to get someone closer to the roof, and it is not a verdict that the roof has failed.

Is a roof rated 3 for age as urgent as one that leaks?

No. A roof given a 3 because the tiles or slates are worn is mainly a cost to plan for, while signs that water is already getting in need sorting soon after you move in, or before.

A tired concrete tile roof on a post-war semi may keep the weather out for a while with repairs, and the real question is whether you want to budget for a new covering in the next few years. An active problem looks different: wet or stained timbers and felt in the loft, damp insulation, or a brown patch on a top-floor ceiling. If the survey mentions any of these, our guide to a damp patch on the ceiling explains the usual causes.

Chimneys often pick up a 3 for cracked flaunching around the pots, open pointing or lifted lead flashing. These are usually chimney repairs that can be priced on their own, though the stack still needs safe access, which a good quote shows as a separate line.

What should you do before you exchange contracts?

Get the roof inspected and priced properly, then decide with the figures in front of you.

1. Talk to your surveyor. Ask what they saw, which parts they could not see, and how urgent they think the work is.
2. Get roofers' quotes in writing. The HomeOwners Alliance suggests at least two, so you can compare scope and price. Ask for an itemised quote with photos of each defect, which makes it clear whether you are looking at a repair or a full re-roof.
3. Use the quotes to negotiate. You can ask for a lower price or ask the seller to have the work done before you buy. The HomeOwners Alliance advises keeping any reduction sensible and in line with the cost of the work. For published price ranges, see our guide to new roof costs in Yorkshire.
4. Keep your lender and conveyancer informed. Yorkshire Building Society says you need to contact your lender if you renegotiate the price. The lender can also apply a retention, holding back part of the loan until the work is done, and Finder notes that firm quotes from a tradesperson can get it reduced or removed.
