How Do I Know If My Roof Needs to Be Cleaned?
Seven signs your roof is overdue for a cleaning — and why most homeowners in our area miss them until it's too late.
"It doesn't look that dirty" — the most expensive sentence a homeowner can say about their roof. Learn the specific signs before serious damage sets in.
THE WARNING SIGNS
7 Signs Your Roof Is Overdue for a Cleaning
Some of these are visible from your driveway. Others require a closer look. All of them mean it's time to call a professional.
- Dark Black or Grey Streaks: Gloeocapsa Magma algae feeding on shingle limestone.
- Green, Fuzzy Patches: Moss lifting shingle edges and creating pathways for water.
- Grey, Faded, or Uneven Color: Early-stage algae or biofilm spreading across the surface.
- Crusty, Scaly Growth: Lichen bonded at a cellular level, requiring professional treatment.
- Debris Buildup in Valleys: Trapped moisture accelerating rot in vulnerable areas.
- Granules in Gutters: A sign that algae is weakening the shingle surface.
- Over 2 Years Since Last Clean: Organic growth is almost certain in our climate within 2 years.
QUICK ASSESSMENT
The 60-Second Ground-Level Check
From the ground, look for vertical streaking, green patches, crusty growth, or debris accumulation. If you check even one item, it's worth an inspection. Two or more means a cleaning is overdue.

WHY THIS AREA IS DIFFERENT
Montgomery County Makes This More Urgent
Montgomery County has 90%+ average summer humidity and heavy seasonal pollen. What takes 3-4 years elsewhere takes 12-18 months here. The conditions are ideal for algae and moss.
