How to repair hole in corrugated garage roof

ouraggie

Hi. Someone or something has made a hole in our garage roof, about 4" diameter. The roof is corrugated, made of a concretey material. Wondered if anyone has any ideas on how to repair it without replacing the whole sheet.
Thanks.

Thanks, Firefox. We did wonder if it was asbestos. Certainly looks like it!
Looks like it may be a bigger job than we thought. (I had suggested to OH that we get a piece of corrugated roofing plastic, stick this down onto the original roof over the hole and seal the edges with exterior sealant. )

I bought a garage that looked to have an asbestos roof, but when I got the plans, it says it's non-asbestos.
So if there was any planning for the garage, check that first before worrying about asbestos.
For the repair, google roof repair patch and see what's avaliable.

Depends how pretty you want it to look really. If you just want it patched up, i had a simular issue and literaly just cut a piece of corrugated plastic to the rough size and used a load of sealnt around it, needs resealing every 6 months or so but does the job, at least untill i replace the whole roof (one day...)

A planning application is of no use whatsoever in working out what the material is. Plans get changed between design and construction, and even if a non-asbestos material is specified that doesn't mean a non-asbestos was actualy used.

The only way of confirming or ruling out the prescence of asbestos is to get the material professionally tested.

This is the kind of situation where the danger exists. Most sealants suggest the surfaces it is applied to need to be clean and free of dust. Hopefully you didn't follow this advice and hopefully the OP will seek reliable information on the dangers of working with asbestos rather than giving it a good scrub with a wire brush to get a decent seal.

Asbestos is usually ok if it is in good condition and left alone. Damaged asbestos, and asbestos that needs to be worked on is an acknowledged and widely understood risk to health.

It is disappointing that people advising DIYers of the risks they might be unaware of are potentially going to be branded "the asbestos police". After all, we are talking about a material that has the ability (in very small quantities) to cause a very slow and painful death. :wall:

Rather than the snide remarks, how about explaining why you believe the OP would be perfectly safe carrying out a DIY repair of a garage roof which might be asbestos?

Why do you find it so offensive that other posters want to make sure people understand there are risks attached to working with an unknown material?

Keep the policing up.

Should we take the lack of any justification for your claims to indicate you haven't got a clue what you are talking about then? It would be nice for other posters if they know whether they are being advised by someone with expertise, or just someone who thinks elf an' safety has gone mad.

I won't drag this exchange on & will end it by saying I have worked with asbestos sheeting for over 45 years.

Great to hear. So you will of course be fully aware of HSE guidance on working with asbestos products and always applying that in everything you do. Unlike some of the cowboys in the industry who think it macho and tough to pretend there is no risk.

Strange then that you don't seem to want innocent DIYers to benefit from the same level of advice so they can make their own informed decision, but each to their own I guess.

So let's call a Christmas truce, and spare a thought for the families of the estimated 2500 of our former colleagues who died from mesothelioma in 2017 and won't be sharing Christmas with them. I suspect very few of those people wouldn't want to turn the clock back and have someone tell them there is no such thing as 'safe' asbestos and always to take care when working with it.
