keeping condensation out of a garage

[swiftb]

I have a detached single garage which is a concrete sectional effort with a corrugated asbestos roof. This time of yr it suffer badly from condensation.
Parked my bike in there about a week ago ready to sorn it over winter. The condensation seems worse every year and I got the bike out yesterday to already find mould growing on it here there and everywhere. Not happy. Cleaned up and re wd40'd the bike all over with a cloth and polished all the plastics.

Whats the best form of defence against the condensation - which literally drips from the roof and forms puddles all over and gets all over my sodding bike ?
A dehumidifier is sounding like an option - any positive reviews from anyone using one?
Ive read that keeping airflow and ventilation also helps but figure its one or the other, as I think a dehumidifier works better in a 'sealed' room. I thought of installing a bathroom style extractor fan right next to the bike? Or is this a waste of time?
Basically I need to keep this moisture down to a minimum at a reasonable cost. DOnt want to go as far as starting to insulate walls etc etc so just something to deal with it for the few months of the year that its an issue.

Ventilation.
Water in the air will condense any cold surface.

Fit more vents.

I had literally the same problem this time last year. Got soaking whenever i went in there. Especially as you open/shut the door it vibrates the whole garage and makes water drip all over everything

What I did was to put rockwool insulation up, with wooden struts all along on the regular wooden roof holder-uppers. Basically branching across.

Then put hardwood up against that and haven't had a drip yet! Isn't properly cold yet but it is going well.

Didn't cost too much either. Probably £40 for all of the hardboard, £20 for all of the timber and maybe a £10 for the rockwool. That is maximum, though. Can't remember exactly.

Money probably isn't an issue for you with a post 2006 gsxr either

But make sure to wear shitty clothes and you should really wear a mask and eye protection but I didnt Is a pain in the ass and putting the rockwool up then screwing the hardboard up cannot be done alone.

We had the hardboard cut up into 4 to make it easier to get home/put up too!

get an insulation company to do spray insulation on the roof. probs a little more than rockwool, but much less fart on!

A dehumidifier will only do one thing - cost a sodding fortune to run!!

I was gonna do the walls too but seeing as its a coucil garage cba with the extra money. Have already built a workbench and spent a fortune with decent locks, bolts and wall fixings

Then floor paint and paint for everything and lights and wiring. Nearly got kicked out the other day, what a waste of money that would have been!

Cheapest solution is probably to drill holes in the walls. For bonus points, angle them downwards to minimise water ingress.

Basically it was my dads and my garage but it was in his name and he never paid.

He then gave me the card and I started to pay. I forgot one week and father got a letter to say we would be evicted. Turns out the account has been minus since it was opened over a year ago!

So I have now set up a direct debit but I had 24 hours to get the money and nobody I knew could lend me the money but I managed to scrape it up.

And I haven't noticed the temperature really. Well sort off, I don't get cold when I get rained on in there

I had a similar problem in my shed,so I bought some anti-condensation paint from Screwfix and this cured the problem.But I only had the situation on really cold nights,despite proper ventilation.It is mainly to do with the corrugated sheet steel that I have as roofing.It is like an oven in there during the Summer,but like an ice box during the Winter.
