The short answer
No licence is needed for intact asbestos cement roof sheets that are removed carefully and not broken up. The HSE classes that as non-licensed work, and says age and weather alone do not move it. Where the sheets are badly damaged, or the method would smash them, the job moves up to the notifiable group, which adds notification, medical and record-keeping duties for the contractor.
What non-licensed means for a whole-sheet garage roof
HSE guidance sorts asbestos jobs into licensed work, notifiable non-licensed work and non-licensed work. A garage roof of whole sheets sits in the lowest group. The Executive names asbestos cement products, with roof sheeting and rainwater goods as its examples, and says the work stays non-licensed where the sheets are lifted off whole and never broken into pieces. Its page on non-licensed work page adds that cement which has merely weathered is still inside that group.
Non-licensed does not mean unregulated. HSE says asbestos cement tasks should be carried out by trained workers, so whoever does the work still needs to know how to handle the material, and the waste still has to be dealt with properly. The label means no licence is required for the job. Moss, pale surfaces and surface roughness, all normal on a garage roof of that age, do not push you into a stricter group.
When the answer changes to notifiable work
The HSE draws its line at damage and at method. Its page on notifiable non-licensed work lists cement roof sheeting that has been substantially damaged, such as after a fire or flood, as one example. It also covers jobs where the removal itself will reduce the material to fragments and put significant dust and debris into the air, and it gives dropping a cement roof to the ground as its illustration.
That second case catches people out. A roof that is whole today can become notifiable work if it is taken down by smashing, throwing sheets off the rafters or levering them off in pieces. The category follows how the job is done as well as how the roof looks before it starts. Our guide to asbestos garage roofs and the HSE rules walks through the full position.
The extra duties when work is notifiable
For notifiable non-licensed work, the HSE lists three obligations on the employer. The enforcing authority must be told about the work before the job starts. There is no minimum notice period, and the HSE online form is the only method of notification. Workers must have medical examinations, repeated at least every three years, and a register of the work has to be kept as a health record for 40 years.
None of that falls on you as the homeowner in the same way, but it affects who you hire. A contractor handling broken sheet should be able to explain how they notify the work and where the waste is going. If a quote for a damaged roof mentions neither, ask why. The extra controls also cost money, which is one reason a cracked roof prices higher than the same roof in one piece.
Doing it yourself, and why the licence question is not the whole story
Hearing that no licence is needed, some owners wonder about taking the sheets off themselves. The rule about licences tells you which legal band the job sits in. It does not say the job is safe to improvise. Cement sheet is awkward to get off a roof: the bolts are corroded, the sheets are long and brittle, and a slip on a fragile surface is a fall risk before it is a fibre risk.
If you are tempted, ask yourself three things. Can you unfix every sheet without cracking one? Do you have somewhere approved to take the waste, which a household skip is not? And would you know what to do when a sheet splits halfway down? A contractor who does this routinely has answers to all three. Planning to replace the roof anyway makes the question simpler, because the same visit can price both the removal and the new covering.
Questions to put to anyone quoting
Because whole-sheet removal needs no licence, the useful questions are about method rather than paperwork. Ask how each sheet will be unfixed: whether the fixings will be cut or undone, and the sheets lifted off one at a time. Ask how they will be wrapped and stacked, and where they will go. Ask what happens if a sheet cracks mid-job, and whether the price moves when it does.
Ask, too, to see the plan for the new roof in the same document. If you are not yet sure the sheeting contains asbestos at all, look at what an asbestos test costs first, because there is no point arranging controlled removal for a roof that turns out to be ordinary fibre-cement.
Where our survey fits, and what you get in writing
We survey the roof first and photograph its condition. The quote then tells you whether we read it as whole sheet or damaged sheet, because that decides the controls and the cost. The quote covers access or scaffold, the careful take-down, waste carriage, the new roof and the tidying up, and it arrives after the visit. Waste is taken away and the site cleared.
If the survey finds sheets broken beyond careful handling, we tell you plainly and explain the route that follows, including the notification step. Our garage roof lifespan answer shows typical lives for the replacement coverings, and the main garage roof replacement page covers the job as a whole. The finished roof carries a 10-year workmanship guarantee in writing. Call 01453 933613 or send photographs through the enquiry form.
