This summer/fall, I installed a new roof in the cold garage (wood paneling) and a few days ago, to my horror, I discovered mold (green and black) on the inside. I have essentially completely renovated it since I had problems with water damage and mold in the previously insulated garage. I left the crossbeams that didn't seem to be affected and brushed them with a product that was supposed to prevent potential mold growth (a safety measure, so to speak).
Devastating. What should I do? Grateful for any tips!

PS. The garage is from the 1960s.

I would review the ventilation and measure the humidity. Is it a cold garage or a heated garage with a cold attic?
If it is a cold garage, perhaps a solar air heater might solve the problem with high humidity, which is probably the issue if it's a new roof and there are no leaks.

It doesn't seem uncommon for newly laid timber to mold. It probably hasn't been dry enough. I assume you're talking about the roof, and that it's covered on the other side, i.e. moisture-proof, so the moisture in the paneling can only be ventilated inward.
Can you see if the mold seems to follow the boards?
If it's due to moist new timber, it should have dried out sufficiently by summer/fall. Then you can treat it again if you feel it's necessary.
Otherwise, it could be due to poor ventilation. That is, all the rain and snow brought in by the car create a damp environment resulting in mold. My cold garage is clearly ventilated enough since I don't have mold problems, despite a cold and wet car coming in every night during the winter months.

Thank you for your answers. Yes, it's not unthinkable that the boards have become a little damp when they've been left and that it can then cause problems with a tight roof. It's unfortunate in any case.
Now I have brushed on Mögel fri-medel and sincerely hope that it helps. I'm thinking of applying it once more - does anyone have tips on a good product?
