If you have a home in Hawaii, your roof may turn green or show black streaks as it ages. Over time, your roofing will become an inadvertent garden for moss and algae due to consistent moisture exposure. While they may not be apparent at first, these substances will create long-lasting stains if they aren’t removed. Here’s what causes the growths and how you can keep them from happening.

Why Are Mold & Algae Growing on My Roof?

It’s easy for the spores to take hold if they land on the roof because the surface provides the perfect conditions for growth. Hawaii’s sunny, humid weather creates a warm, moist environment that the spores prefer, and the filler roofing material gives them nutrients.

Initially, the algae and mold will create dark streaks or a speckled appearance, centralizing in the seams between shingles. If these blemishes are ignored, they’ll degrade the fillers in your roofing material and saturate the surface with moisture, making your home susceptible to leaks.

How Can I Prevent Growth?

Safeguard your roof by having it professionally cleaned and coated with a protective barrier. The initial cleaning will help the team determine whether the growth caused any underlying structural problems. Once any necessary adjustments are made, the roof will be coated with a protectant to extend its life span and hinder further algae and mildew growth.
