What’s Growing on Your Roof? How Algae, Moss, and Fungus Can Damage Your Home

Your roof is your home’s first line of defense against the elements, but it’s constantly exposed to rain, snow, and harsh UV rays. Over time, this exposure creates the perfect environment for unwanted growths like algae, lichen, moss, and fungus. If left untreated, these organic materials can cause significant damage, leading to costly repairs or even a full roof replacement.

The Hidden Dangers of Roof Growth

A roof covered in black streaks and moss isn’t just an eyesore—it’s a financial liability. Black algae, in particular, feeds on the limestone in asphalt shingles, causing them to curl and deteriorate. Once this happens, it’s too late for cleaning; you’ll need a full roof replacement.

Here’s what unchecked roof growth can lead to:

  • Shingle Damage – Algae and moss break down roofing materials, reducing their lifespan.
  • Higher Energy Bills – A weakened roof provides less insulation, forcing your HVAC system to work harder.
  • Water Retention – Moisture-trapping growths make your roof heavier and less effective at shedding rainwater, potentially damaging your gutters and drainage system.
  • Costly Roof Replacements – Severe roof damage can require a full replacement, often costing over $10,000.
