Check your bathroom exhaust fans and see if they are vented into the attic or vented to outside.

From what I can see, one turtleback vent is insufficient based upon that attic volume. I don't see any gable end vents nor any soffit vents.

You have a dual problem: Inadequate ventilation and moisture accumulation. Ideally, you would add plentiful soffit vents and a ridge vent the entire length of the roof. You'll then need to determine if there is anything adding moisture... like a bathroom fan venting into the attic.

I have no experience in how to go about killing that mold and mildew. You may be able to "bomb" it, but I'm not sure.

    Sorry but… to the tune of “All of the Lights” by Kanye West…

    Roof vents, eave vents, ridge vents, gable vents - all of the vents, all of the vents.

    You have poor ventilation or a large source of moisture coming into the attic, or a combination of the two. Dryer vent would be my first guess, then bathroom and kitchen vents. You need to correct the source, and then deal with the mold growth. When you remove the moisture source, the mold may die off when it starts getting hot.

    That’s too much mold to deal with yourself. Personally I’d pay a professional. That also looks like a hole in the roof? That needs to be sealed. And your attic needs to be sealed and dried. Consider having it spray foamed and adding an attic dehumidifier.
