Mold Removal

Have you ever wondered what causes those ugly black streaks on your roof?

Gloeocapsa Magna is an algae that thrives in warm and humid climates. It normally appears first on the north slope of the roof where shade is prevalent and moisture tends to accumulate. As the algae accumulates, it becomes visible as dark streaks on the roof.

HRA Home Improvement can remove those unslightly streaks from your roof with our biodegradable, non-corrosive solution that requires NO damaging power washing or brushing. No rinsing is required, and your landscaping will not be harmed.

Our cleaner removes green and black algae, mildew, fungus, and lichen stains from:
