Mouldy roof .. what to do

[owas]

There was a leak in my gym shed for ages that I probably should've got round to a while ago, the plywood has rotted and is now mouldy (or w.e this yellow stuff is)

I now have a steel roof over the top, so the ply doesnt matter but I need to do something about the mould but I'm not sure what?

Types of Mold That Are Yellow
There are several types of fungus that can appear yellow in color including:

• Aspergillus — some forms of aspergillus will appear yellow in color. This is a very common household mold that can be found anywhere there has been any kind of water damage.
• Serpula lacrymans — This may be discovered as yellow fungus on wood. It is often called house eating mold because it feeds on wooden structures and quite literally eats away at the house.
• Mucor — This mold strain is initially yellow or white in color but eventually turns to gray. This is one of the fastest growing strains of mold and has very dangerous side effects when exposure occurs. This mold strain can cause a life-threatening infection called Mucormycosis where the mold invades the blood vessels in the body, causing the blood supply to be compromised.
• Epicoccum Nigrum — This strain of mold ranges in color from yellow to orange to a light brown color. This is another very rapidly growing strain of mold that can be found on a myriad of different household surfaces including; mattresses, carpets, wood, drywall and painted furniture.
• Geomyces Pannorum — this strain of yellow mold is unique in that it thrives in cooler environments whereas most other mold strains prefer warmer climates. This type of mold is common in the northern hemisphere, but not so much in the south. It is a yellow-brown color and can be found on many different damp materials including; walls, floors, wood and paper.

very good Dale...1st thing is buy a decent mask and start cutting out the mold..hard job to remove the plywood now its been covered..looks like its still getting water ingress between boards and whatever is on top..

Horrible stuff, get a good mask and rip it all out.

Edit, the timbers look rotten too, are they load bearing?

The timber seems ok to me,
It is just this section of the plywood that rotted, the rest looks the same as when it went up.

I'll get it cut out


On top is a 1x4 frame with the metal sheeting screwed to that.

Insulation and a vapour barrier next or it's going to rain with condensation in there, I put a tin roof on my garage and created my own micro climate!

Just be careful when dealing with mould, a friend of mine now has serious health issues due to pressure washing mould without a mask
