VA guidelines require that “The surface requiring treatment must be thoroughly washed, scraped, wirebrushed or otherwise cleaned to remove all cracking, scaling, peeling, chipping and loose paint and then repainted with two coats of a suitable nonleaded paint, or:The paint shall be completely removed or the surface covered with a suitable material such as gypsum wallboard, plywood or plaster before any painting is undertaken if the paint film integrity of the surface needing treatment cannot be maintained.” 

I would wait 24 hours of low spore count before continuing work.Buy different color bags for mold material.

I get materials delivered on site so my foreman doesn't have to get them.

I would suggest either a high quality asphalt shingle with a Lifetime warranty (50 years material, up to 25 workmanship guarantees) or a natural slate tile.
