The short answer
For anything built or refurbished before 2000, yes, a survey is the sensible first step. HSE says to assume such a building contains asbestos, and roof sheets, soffits and rainwater goods are common places for it. A survey tells you what each material is before anyone cuts, drills or strips it. MyJobQuote gives a typical UK survey figure of £325 (Sep 2026).
Before a roofer lifts a sheet on an older commercial building, someone should know what that sheet is made of. A survey answers that.
Why the year 2000 matters
HSE's advice on whether asbestos is present is short. Where a building was put up or refurbished before 2000, you assume there is asbestos in it. That is a starting position, not a finding, and it means the building is treated as suspect until a laboratory result says otherwise.
Does that cover a modern-looking unit?
Look at the whole history of the site, not only the date on the plans. A unit put up after 2000 may be bolted onto an older shed, or an older roof may have been re-clad in part. A refurbishment before 2000 counts as well, and a building with a long record of small alterations can hold materials of several ages side by side.
Somerset Building Control makes the same point from its side of the desk. On its asbestos page it warns that pre-2000 buildings are likely to hold asbestos fibre in some of their materials, and that building work will meet them. A roof strip is building work. Skip the survey and the first sign of asbestos may well be a broken sheet and a stopped job.
What a survey looks at
A survey for roof work looks at the materials the work will touch: the roof sheets, any lining beneath them, ridge and flashing pieces, gutters and downpipes, and the soffits and fascias along the eaves.
Can you tell what is asbestos by eye?
Not reliably. HSE accepts that you cannot easily separate AIB (asbestos insulating board, a flat board used in places such as soffits) from look-alike boards that contain none, and it names external soffits as one place AIB turns up. Cement sheets that look alike can differ in content. That is why a surveyor takes small samples for laboratory analysis, and why a roofer glancing at a photograph cannot give you a yes or a no.
The result is a list of materials with their location and condition, which a contractor can price against and plan from. It also shapes the method. Lifting intact asbestos cement with care is non-licensed work under HSE's rules, smashing it up makes the job notifiable, and taking down AIB soffits is often licensed work, with the answer resting on how HSE's risk assessment rules treat that particular job. Each of these is checked, in that order, before anything starts, so nobody is surprised halfway through.
What a survey costs
MyJobQuote gives £325 as the typical UK price of an asbestos survey (Sep 2026). That is a national guide for orientation only, and a surveyor will give a firm figure for your site. A small lock-up and a multi-bay industrial building are different jobs, and the number of materials to sample moves the cost.
Is it worth paying before the roof quote?
Often it spares you a worse bill. Stopping a job part-way to test a sheet leaves scaffold standing idle and a crew sent elsewhere. A survey done first lets the roofer plan the scaffold, the working method and where the waste goes before quoting once, and it avoids the awkward call about a discovery on a Friday afternoon.
A survey for the same building may already exist. Ask whether a previous report is on file before paying for another, and check that it covers the roof and the eaves, not only the interior. An old report is a useful lead, though a roofer will want to see which materials it actually sampled.
Who arranges it, and what we do
The survey is normally arranged by the owner or whoever manages the building, such as a landlord or a managing agent, because it records information about the building itself. If you are a tenant, read your lease and ask who holds any existing records.
Where does a roofer fit in?
We begin with our own look at the roof from safe positions, and the pictures in our report show the roof exactly as we meet it, with each material that worries us marked. Where the building dates from before 2000, we raise it straight away and ask whether an asbestos survey exists. A roof that is plainly AC is treated as AC from the start, and the scaffold, the method and the waste route follow from that. A single written price comes afterwards, with no surprises about the sheets.

More on surveys and roof work
My roof is metal, so does it need a survey?
A metal sheet is not asbestos, but a pre-2000 building can still hold asbestos elsewhere in the roof zone, such as soffits, a lining or old gutter sections. Roof work often touches those parts. A survey of the materials in the work area is still the sensible step before anyone cuts or strips anything.
Can the survey be done after the roof is quoted?
It can, but the quote then rests on an assumption and may change if a sample comes back positive. A survey first means one price that already reflects the method and the waste route. If a survey is under way, tell us the date and we will fit our own roof survey around it.
