What a homebuyer survey does (and doesn't) tell you about a roof

30 September 2026 · 5 min read

If you're buying a home, you've probably booked, or been advised to book, a survey. Surveyors do a demanding job, covering an entire house in a single visit, and a good survey is well worth having. But a survey covers everything from the foundations to the chimney, and the roof is only one part of it. It helps to know what that part is designed to tell you, and where it stops.

Which survey are we talking about?

The most common one for an ordinary home is the RICS Home Survey Level 2, which many people still call the HomeBuyer Report, its old name. Level 1 is a shorter, more basic report, and Level 3 is a fuller building survey, often chosen for older, larger or unusual properties. A lender's mortgage valuation is something different again: it exists to tell the lender whether the property is reasonable security for the loan, not to give you a condition report.

The rest of this article is about Level 2, because it's the one most buyers have.

What it does tell you about the roof

• The general condition, as far as it can be seen. The surveyor looks at the roof covering, chimneys, flashings and rainwater goods, and rates them so you can see what needs attention and how soon.
• Visible defects. Slipped or missing tiles, cracked or damaged areas, signs of movement, and ponding on flat roofs.
• What's going on in the loft. Where there's safe access, the surveyor goes into the roof space and looks at the structure, paying attention to parts that are prone to damage or decay.
• Where to dig deeper. If something looks like it needs a closer look, the report says so and recommends further investigation before you commit. That's built into the format, and it's a strength of it.

What it isn't designed to do

None of these are failings. They are the limits of a visual, general inspection carried out in one visit.

• It's a visual inspection. The surveyor looks at roofs, often from the ground, from neighbouring public property if needed, possibly with binoculars. Climbing up onto the roof is usually not part of the service.
• Loft contents stay where they are. The surveyor doesn't lift insulation or move stored belongings, so areas underneath aren't seen. They have a lot of house to cover in their alloted time.
• Some areas simply can't be reached. A loft with no safe access, a steep or high roof, or the far side of a roof may only be partly visible. When that happens, the report should say what couldn't be checked.
• It doesn't put a price on repairs. The report can say a roof needs work, but it doesn't cost that work or say how it should be done.
• The roof is one of many things on the list. A surveyor is a generalist by design, covering the structure, damp, drainage, services and more within a single visit.

Reading the roof section of your report

Pay attention to three things. First, the condition rating given to the roof, and whether the report separates different roofs, such as the main pitch and an extension. Second, any "limitations on the inspection" notes, which tell you what wasn't seen. Third, any recommendation for further investigation or a specialist opinion. If you see one, take it seriously. It's the surveyor doing their job properly, not hedging.

When a specialist second look is worth having

• The report recommends further investigation of the roof.
• Parts of the roof or loft couldn't be inspected.
• It has a flat roof, a specialist covering, or an older or unusual construction.
• The report suggests the roof needs major work or replacing and you're thinking of renegotiating or walking away.
• You're selling and have been told the roof needs replacing, and want to know if that's really the case.

Think of a survey as a general check-up: it will spot a scorched socket and tell you to get it looked at, and an electrician then works out why it happened and what to do about it. A roof inspection does the same job for your roof. I can tell you its overall condition, how much life it has left, where it has leaked in the past, and whether earlier repairs were done properly or are likely to cause trouble later.

Where I come in

I inspect roofs and write up what I find, with photographs, in plain English. I don't do repair work, so I have nothing to gain whether the roof is brand new, or is dire need of repair. A roof inspection is also not a replacement for your survey. It's a closer look at one part of the property, for the times when the roof is the thing that matters.
