The Danger of Skipping Cleaning
Moss Destroys Shingles
Moss roots lift and crack shingles, breaking the protective seal and letting water seep into your roof deck — causing rot over time.
Algae Weakens Shingles
Dark black streaks are algae feeding on shingle limestone. Left untreated, it strips granules that protect against UV rays.
Debris Traps Moisture
Leaves and pine needles hold water against your roof surface — creating the damp environment mold needs to thrive.
