The short answer
It may be. HSE's rule of thumb is to presume asbestos where a building dates from before 2000, whether built or refurbished then. Sound asbestos cement sheet can come off as non-licensed work when handled with care. Anything needing a licence is passed to a specialist firm, and you hear what the survey suggests before anything is touched.
Garages on estates of this age were often roofed with corrugated cement sheets, and some of those sheets contain asbestos fibre. You cannot tell by looking, so the safe approach is to treat the sheets as suspect until a test says otherwise.
Q3.1What does HSE say about cement sheets?
Under HSE guidance, taking asbestos cement roof sheets off with care counts as non-licensed work, and that includes sheets that are weathered but not otherwise badly damaged. Once the sheets are substantially broken, or taking them off would crush them, the job becomes notifiable non-licensed work: the enforcing authority is told before it starts, medical examinations follow and health records are kept. We judge the condition of the sheets first and then explain which category applies.
Q3.2What about soffits and insulating board?
Asbestos insulating board, or AIB, is a different material and can occur in older soffits. Plain sight does not separate it from non-asbestos board, and HSE lists most removal of it as licensed work, which goes to a specialist firm, so we stop and advise you before going near it.
Q3.3What about waste and cost?
Asbestos waste from a home needs a consignment note and a registered waste carrier. MyBuilder, updated 21 August 2026, gives a typical national range of £350 to £1,295 for removing a single garage roof, and that excludes any new covering. The written quote after the survey shows our figure.
If you are not sure what your garage roof is made of, send us photographs of the sheets and, if you can see it safely, the underside, and we will point you to the sensible next step. Please do not drill, scrub or pressure-wash the sheets while you wait, since that is how fibres reach the air.
