What method do you recommend for cleaning low-slope, residential metal roof? Mopping (with what type cleaner?)
steam cleaning? Or pressure cleaning?
Any precautions? And what might be a reasonable cost for about 1500 square feet?
Thanks for your early reply.

This question is best asked of the manufacturer. Appreciate that there are many differant types of paint systems by differant manufacturers.
A safe solution that we recommend is to mix some liquid TSP with some sunlight dish soap and household bleach (2%). Apply with a garden hose applicator and if some scrubbing is required, use a soft car wash brush then rinse. The TSP will loosen the grime, the dish soap will keep it loose and the bbleach will disinfect and kill any spores.
