If you’ve ever noticed those ugly black streaks crawling across rooftops in the summer, you’re not imagining things! The hot, humid weather in Columbia, MD creates perfect conditions for algae, moss, and lichen to flourish on your roof. Let’s break down why this happens and how Maryland Pro Services can help protect your home.
Why Algae and Moss Love Summer Sunlight
Warmth + moisture = algae paradise!
Here’s why your roof becomes a target:
Longer sunlight hours heat roof surfaces, encouraging moisture evaporation — but not fast enough to dry everything.
Humid nights leave dew on shingles, feeding algae and moss.
Roof crevices hold onto moisture, providing the damp environment algae love.
Specifically, those black streaks you see? That’s likely Gloeocapsa magma — a type of blue-green algae that thrives on shingles. Maryland Pro Services offers expert Roof Cleaning to safely remove these streaks before they cause damage.
How Algae Growth Harms Your Roof
Algae and moss aren’t just unsightly; they’re destructive:
-
Traps moisture under moss mats, leading to rot
-
Weakens shingles by lifting or curling them
-
Shortens roof lifespan by promoting mold and lichen spread
-
Reduces energy efficiency by darkening your roof, which absorbs more heat
A professional soft-wash roof cleaning by Maryland Pro Services can remove algae and moss without damaging delicate shingle materials.
How Does Summer Weather Accelerate Roof Algae?
Here’s what people also ask:
Why does algae grow more in summer?
Warm, moist conditions make summer the peak season for algae, especially in shaded or north-facing roof areas.
Are black roof streaks dangerous?
They won’t collapse your roof overnight, but left untreated, they can degrade materials, reduce roof lifespan, and even hurt home resale value.
Can pressure washing remove algae?
Yes, but it’s best done with soft-wash techniques to avoid damaging shingles. That’s why professional help is recommended.

Preventing Algae Growth in Summer
To stay ahead of the algae battle, follow these tips:
-
Schedule annual roof cleanings before or after the peak season.
-
Keep trees trimmed back to reduce shade and improve air circulation.
-
Check and clean gutters so water flows away properly.
-
Install zinc or copper strips near roof ridges to inhibit algae growth.
Maryland Pro Services provides not just cleaning, but proactive solutions to help your roof stay algae-free longer.
