Moss and algae are typically bad signs on a roof and indicate potential damage as the roots end up breaking the shingles and the layers present underneath high forms cracks and weak points in your ceiling. Another thing that moss can do is that it can trap moisture which can also spell trouble. If your roof has moss, then you need to clean it out as soon as you get the chance.
