The longer it is left untreated, the worse the damage to roofs. This is why removing stains should be a priority for homeowners. Roof stain is essentially fungus and mildew spores which are embedded in the shingles from nearby shrubbery, trees, and plants. All roofing are vulnerable to stain damage and that is why it is important to know how to remove roof stains and maintain them.

DIY solutions

Homeowners who would like to make some savings on roof stain removal cost can resort to DIY solutions. But before we start we want to warn you that climbing onto your roof is extremely dangerous and it can cause injuries if you are not careful. This is especially with houses that have large roofs.

The requirements include non-corrosive and non-toxic roof cleaning chemical, a garden hose, a garden sprayer and a full-body harness. Special tool applicators and even rinsing tools may be required for severe roof staining. The roof cleaning product that is selected should be safe for the environment and non-corrosive.
