Homeowners dread the day they find black streaks on their residential roofing, a sign indicating the presence of mold. What may seem to be mold might, however, actually be algae. The more important question here would be is algae as bad as mold? Crown Roofing LTD, one of the city’s top roof repair companies, answers that question by elaborating on the differences between the two.

Damage to Your Home

While similar in appearance, mold is more destructive than algae and is harder to remove. Mold is a type of fungus that can eat away organic materials, causing wood rot and weakening the structural integrity of your roof. Algae, on the other hand, is a moss-like plant that won’t do damage to your roof, except for diminishing its aesthetic appeal.

Lower Resale Value

First impressions count. Algae-infested residential roofing, however, can be a deal breaker for potential buyers. Blackened parts of your roof are unsightly and can significantly lower your home’s resale value. Since algae is easier to remove than mold, you can simply have a professional give your roof a good wash.

Health Risks

The problem with mold goes beyond just the appearance and structural integrity of your home; mold spores are a health risk to people with respiratory complications and compromised immune systems.
