Roof survey or RICS homebuyer survey: what is the difference?

A homebuyer survey is written by a surveyor and describes the condition of the whole house. The roof sits alongside the walls, damp, floors, windows, services and the garden, so it gets a section, not a chapter. The surveyor will normally rate the condition and say whether anything needs urgent attention or further investigation before you commit.

That breadth is its strength. You learn about a damp problem or a worn boiler as well as the roof, and the report is geared to your lender and your decision to buy. What it cannot offer is roofing depth. A surveyor covering a whole property has limited time on any one element, since the same visit must cover the structure, the damp, the drains and the rest, and often judges the roof from the pavement, a hatch in the ceiling or a neighbour's garden. The report will state how it was inspected, so read that line closely before relying on the rest. If it says the roof was seen only from a distance, treat any comment about its condition as provisional, and expect the sellers or your solicitor to be asked for more.

A roof survey goes up, or uses a drone or camera, to look at the covering closely. It records each tile, slate or membrane area, the ridge and hip lines, the verges, the flashings round chimneys and abutments, the valleys, and the gutters. It adds photographs of the faults, which a general survey seldom has room for.

The output is more useful for pricing. It tells you which faults are minor and which are structural, whether the covering is nearly worn out and what the sensible repair or replacement would be. Our answer on what a roof inspection report should include lists what a thorough one contains. Checkatrade's September 2026 table puts a roof survey at £300 to £500 and a drone survey at around £210, plus VAT, depending on the roof, its access and how much photographic detail you want.

Surveyors flag a roof for many reasons, some minor and some serious: slipped or missing tiles, signs of patching, moss, a sagging ridge line, stained ceilings in the loft or simply an age that suggests the covering is tired. A phrase such as 'further investigation is recommended' is the signal to get a specialist in before you exchange contracts.

At that point, ask a roofer to look and put the findings in writing with photographs. A repair may be modest, and you can use the quote to negotiate with the seller. A full replacement is a very different sum. Either way, you decide knowing the figure. Our roof inspections and surveys page explains how a survey is done, and how long a roof inspection takes helps you plan around a purchase timetable.

No survey sees everything. Neither one lifts tiles to examine every batten, and neither can see inside a cavity or under insulation without opening it up. Spray foam in the loft is a good example. The RICS consumer guide tells owners to ask their lender whether spray foam is acceptable, and says it can bear on a surveyor's view of value. In November 2024, some lenders said they would refuse such homes, and the rest decided case by case.

If the loft has been sprayed, read our page on spray foam insulation removal. Homes built before 2000 may also contain asbestos in roof materials, which the HSE tells people to assume. An inspection can note suspect materials, but only testing confirms them.

For most buyers the order is simple. Commission the homebuyer survey, read what it says about the roof, and only add a roof survey if the report asks for one or the roof looks old, patched or complex. That avoids paying twice for an opinion you did not need, while giving you a specialist view where the stakes are higher. A newly built or recently re-roofed house rarely needs the extra report, and its paperwork may answer the question for you.

If you are buying a house with a flat roof, a chimney stack in poor order or a conservatory roof, a roof-only survey is more likely to be worth it. Once you own the house, keep both reports; they form a baseline for your first repairs. Selling instead? See roof inspection before selling. Either way, ask for a written price with one total, so you can set the work against the asking price. If the survey finds more than you expected, you then have the facts to renegotiate, or to walk away, before you are committed.
