The Importance of Roof Cleaning
The dark streaks commonly seen on Louisiana roofs are often caused by algae that thrives in warm, damp conditions. North-facing slopes, shaded sections and areas beneath trees may stay wet longer and show staining first. Pollen, storms and organic debris can add to the buildup.

Humidity: Warm, damp air keeps roof surfaces wet and encourages organic growth.
-
Shade and rainfall: North-facing slopes and areas beneath trees often stay damp longer and stain first.
