Why Moss and Algae Are Problems on Clarksville Roofs

Let us start with moss. Moss grows in damp, shaded areas. North-facing slopes. Under tree branches. Anywhere that stays wet for days after a rain. Clarksville's humidity and spring rains create perfect moss conditions. Moss holds water against the shingles. That water soaks into the asphalt. The shingles degrade faster. Within a few years, the shingles under the moss will be soft, cracked, and worthless.

Moss also has roots. They are shallow, but they can work their way under shingle tabs. That lifts the shingle. Wind can then get under it. Water can get under it. A small moss patch can lead to a leak that ruins your ceiling.

Algae (black streaks) is different. It does not damage the shingles structurally. Algae feeds on the limestone ller in shingles. It thrives in Clarksville's humidity. Once it starts, it spreads across the entire roof. It looks terrible. Homes on Fort Campbell Blvd with black streaks look neglected. When you go to sell, buyers notice.

Both can be removed. But you have to do it correctly. We use a soft wash system. Low pressure (like a garden hose). Eco-friendly cleaning solution (sodium percarbonate or zinc sulfate). No bleach. Bleach kills your plants and runs into storm drains. It is also not great for shingles.
