Is your roof turning into a green jungle? Algae streaks or fuzzy moss patches might look harmless, but trust me—they’re bad news. Let’s talk about roof cleaning products that kick these invaders to the curb and keep your shingles looking fresh.
Why Algae and Moss Are Bad News for Your Roof
The Silent Invaders: How Algae Takes Over
Algae might seem like nothing more than annoying black streaks, but it feeds on the limestone filler in your shingles. Over time, this weakens your roof, leading to costly repairs or even early replacement. Yikes, right?

Moss: More Than Just a Green Carpet
Unlike algae, moss is thick and spongy. It soaks up water like a sponge, holding moisture against your shingles. This can warp or lift them, creating perfect spots for leaks. That’s why having reliable roof cleaning products on hand is non-negotiable.
