How to estimate your own roof
Roof area = your home's footprint × 1.2–1.4 (pitch and overhangs). For a one-story home the footprint is simply the home's square footage. For a two-story home, divide the square footage by 2 first.
- One-story, 1,858 sq ft: 1,858 × 1.3 = 2,415 sq ft of roof → 2,415 × $0.25 = $604
- Two-story, 2,400 sq ft: footprint 1,200 × 1.3 = 1,560 sq ft of roof → 1,560 × $0.25 = $390
Steep roofs (the kind you wouldn't walk on) use the 1.4 multiplier; low-pitch ranch roofs use 1.2. When you call, we confirm the exact number from satellite measurement before any work starts.
Those Black Streaks Are Alive
The dark streaks on North Atlanta roofs are Gloeocapsa magma — bacteria that eat the limestone in your shingles. Left alone, it spreads, holds moisture against the roof, and shortens shingle life. Rain won't remove it.
And here's the part many homeowners don't know: pressure washing a shingle roof is the wrong fix. It strips the protective granules off the shingles — visible damage, and a warranty-killer. We only soft wash roofs: low pressure, a solution that kills the growth, then nature rinses the dead streaks away over the next weeks of rain. We'll tell you honestly: the roof often looks dramatically better the same day, but full streak removal finishes with the weather — that's how the chemistry works.

How much does roof cleaning cost in North Atlanta, GA?
Factory Fresh LLC charges a flat $0.25 per square foot of roof area. Roof area is roughly your home's footprint times 1.2–1.4 depending on pitch. A one-story 1,858 sq ft home has about 2,415 sq ft of roof, which comes to $604. Service minimum is $150.
What are the black streaks on my roof?
They're Gloeocapsa magma — a bacteria-algae that feeds on the limestone filler in asphalt shingles. It spreads across the roof, holds moisture against the shingles, and shortens their life. It will not wash away in the rain; it has to be killed with a soft wash treatment.
Does roof cleaning damage shingles?
Pressure washing does — it strips the protective granules and can void shingle warranties. That's why we only soft wash roofs: low pressure with a cleaning solution that kills the growth. The streaks die immediately and rinse away over the following weeks with rain.
How long do roof cleaning results last?
Typically 2–4 years in Georgia's climate, longer on roofs with good sun exposure and no overhanging trees.
