Planning those 'summer' jobs - Garage roof options.

I currently have the dreaded asbestos corrugated sheets on the roof. These apart from the obvious danger aspect, badly leak when it rains heavy soaking the Westy and I have to use a outdoors cover to keep it dry .

 

What do folks suggest the best replacement options are, there appear to be many from what I have seen online.

Richard.

Edit to add.

Its the concrete sectional type and the sheets are fastened to 'L' sectioned angle iron with what looks like threaded bar.

Just a note of caution. Take off with care. Grind off bolt heads and remove sheets whole. Sometimes best when removing to wet it. The health danger is when the partials are released when the sheets are broken. Dispose of to an approved waste site - some will take it without charging you too much and others will want a fortune. 
Normal PPE also required. 
 

There are various options regarding replacement but depends if you are considering changing the roof structure. If you are not, options are reduced to a similar, more modern, alternative. 
 

Either way best to change it.

Yeah thanks, I am fully aware of the dangers. Sadly my grandad wasn't, as that was way before it was found to be dodgy. It killed him, so I will take great care.

No I don't wish to substantially change the structure , but rather wish to replace the current sheets with something that is waterproof and if possible 'green in nature'.

Wickes do a green bitumen impregnated corrugated system which is ok.

I have a feeling this was once used on mine to effect a repair, if they are the same thing they don't cope with hot weather too well, the one I had on there sank in the middle which then filled with water and finally gave way and ended up on top of the Westy - of course they may be stronger these days I don't know.

What’s your budget? 
 

the best long term solution would be to completely strip the roof, add some additional structural support then ply and an EDPM membrane.

Budget - Erm well obviously I don't mind paying for something that works, I have no clue as yet since I don't know what may be best.

If I hadn't  posted my first option was indeed marine ply then possibly heavy duty felt or whatever is better than that although as you say additional braces would be needed, maybe just more 'L' section iron to support the timber

If I had to put a price on it, well £500 would be somewhere about right for what is only a garage, as long as the car stays dry.

My concrete sectional garage has a Coroline roof. It’s probably been there at least 20 years and still OK. I used the same stuff when roofing the shed I put next to it 6 years ago, although that did have a 19mm T&G structure to lay it on.

 

As a replacement for asbestos it’s quick, easy and reasonably budget with pretty good life expectancy.

you’d have to double that budget for almost any sort of flat roofing membrane and the structural works needed. That also assumes you’ll be doing everything yourself.

Geez, really?, oh. You can buy quite a few car covers for that... Well in that case I need to have a re-think. I have a DIY shop at the bottom of the road, I will see what they are charging for materials. Yes, I would be doing it myself, I hate paying for stuff I can do myself.

Thanks for the input.

Just be careful with the existing roof . Do you know if its White, Brown or Blue asbestos cement sheets as they have different levels of risk when handling and disposing of them . You should wear appropriate PPE all the time when working with them

I have the white sheets, which I think are the worst type. As I said I am fully up to speed on wearing PPE etc and I suspect my covid mask isn't up to the job... I was joking I know its not.

I watched my grandad die with inhaling it, not a pleasant sight. He used to refurbish ships in the Liverpool docks in the 60's, they used a lot of the stuff back then.

If you wet the roof when you are removing the sheets, there is less risk of dust being released from them. A fine hose spray will do the trick

Hi, mine was corrugated steel that was 20years old , changed it to steel again from Cladco ( can have it painted, plastic coated , galvanised and have anti drip condensation stuff on it , cut to size and delivered) put on using tex screws into the steel supports. All done in one day by 2 of us , garage 5mtrs x 5mtrs . Andy

Thanks Andy, heard about the stuff but never used it. Can you remember the costings, I just have the typical single garage size wise.

And thanks Ian yes I did read about wetting it before removal, makes a lot of sense to me.
