— ROOF CLEANING · COOKEVILLE
Roof cleaning, gently restored.
Roof stains, moss, and algae aren't just cosmetic. They hold moisture against your shingles, which accelerates deterioration and can lead to leaks. I use a soft wash approach — not high-pressure blasting, which can damage shingles and void warranties. The method kills the growth at the root, rinses it away safely, and helps extend your roof's life. The dark streaks you see on roofs across our service area are Gloeocapsa Magma — a type of algae that feeds on the limestone filler in asphalt shingles. It spreads from house to house on the wind. Cleaning it off stops the damage. When local homeowners search for roof cleaning near them, Exterior Experts provides the soft wash treatment that shingle manufacturers recommend.

What causes the dark streaks on roofs in the Sparta area?
Those are almost always Gloeocapsa magma — a type of airborne algae that grows on asphalt shingles and spreads in humid climates. It's extremely common in Middle Tennessee. Soft wash roof cleaning removes it completely without pressure-washing the granules off your shingles.

How it works
Inspect the roof
I check for damage, loose shingles, and areas of heavy growth before starting. If there's pre-existing damage, I'll tell you before proceeding.
Apply soft wash solution
The cleaning solution goes on at low pressure, soaking into the algae and moss to kill it at the root.
Let it work
The solution needs time to do its job. I let it dwell long enough to kill the growth effectively — not just bleach the surface.
Rinse carefully
I rinse with low pressure, working from top to bottom. No shingle damage, no warranty issues.
Final inspection
I check the roof to make sure the job is complete and verify no damage occurred during the process.
A clean roof looks better and lasts longer. Algae and moss hold moisture against your shingles, which speeds up deterioration. If left unchecked, this can lead to leaks and expensive repairs. Regular roof cleaning is a preventive measure that protects your investment — typically at a fraction of the cost of a premature roof replacement.
I'm worried soft washing will damage my shingles.
Soft washing uses pressure similar to a garden hose — nothing that will harm shingles. The concern most people have is actually about high-pressure washing, which many roofing manufacturers explicitly say voids the warranty. The soft wash method is the approach recommended by major shingle manufacturers including GAF and CertainTeed. If your roof is in normal condition, there is no risk to the shingles from this process.
Can't rain just wash the stains off over time?
No. Those dark streaks are Gloeocapsa Magma — a type of algae that's actively feeding on the limestone filler in your asphalt shingles. It doesn't wash off in rain; it spreads. Left alone, it eats into the shingle coating and shortens your roof's life. Cleaning removes the growth and the spores. Rain after a roof cleaning is actually a good thing — it helps rinse away residual cleaning solution.
How Much Does Roof Cleaning Cost?
Roof cleaning pricing depends on the total roof area, pitch complexity, and severity of algae or moss growth. Heavier growth sometimes requires a second application.
Factors that affect the price
Roof FAQ
Is soft washing safe for my roof?
Yes. Soft washing uses low pressure and professional cleaning solutions. It's safe for all shingle types and won't void your roof warranty. High-pressure washing, on the other hand, can damage shingles and is often explicitly not recommended by manufacturers including GAF and CertainTeed.
How often should a roof be cleaned?
Most roofs in our service area benefit from cleaning every 2–3 years. If your roof is in heavy shade or you see moss starting to appear, don't wait — moss can cause real shingle damage if it gets established.
When will I see results?
The cleaning solution works immediately, but some algae streaks may take a few weeks of rainfall to fully wash away. Moss and heavy growth looks noticeably improved right away. Within 30 days, your roof should look significantly cleaner.
What type of roofs do you clean?
Asphalt shingles, metal roofs, tile roofs, and cedar shake. I adjust solution and approach based on the roof material. Each material has specific requirements — asphalt shingles need a different treatment than metal.
How do I know if my roof has algae vs. just dirt?
Algae typically appears as dark brown or black streaks, often running in lines down the roof. It tends to start on the north-facing side or under tree coverage where moisture stays. Dirt tends to be more uniform and powdery. Either way, if it looks bad from the ground, it's worth cleaning.
Will this prevent moss from coming back?
Cleaning removes existing growth and kills the spores. Zinc or copper strips at the ridge can help slow regrowth over the long term. Moss can return over time — especially in shaded areas — but regular 2–3 year cleanings keep it from getting established again.
How long does a roof cleaning take?
Most residential roofs take 2–3 hours from setup to final rinse. Complex multi-section roofs with steep pitch take longer — up to a half day for very large homes. I'll give you a time estimate when I quote based on your specific roof.
What's the difference between the dark streaks and moss?
Dark streaks are algae (Gloeocapsa Magma) — a flat, spreading growth that leaves dark brown or black lines running down the slope. Moss is a 3D plant growth that physically lifts shingles as it spreads. Both respond to soft washing, but heavy moss requires a more saturated application and a longer dwell time to kill it all the way to the root.
Will roof cleaning void my warranty?
Soft washing — low-pressure water plus cleaning solution — is actually the method shingle manufacturers recommend and what ARMA (the Asphalt Roofing Manufacturers Association) endorses. High-pressure washing can void a shingle warranty. I only use soft wash on roofs, which protects your warranty coverage rather than threatening it.
How long does roof cleaning last?
Most treated roofs in our service area stay clean for 2–3 years after a professional soft wash. Homes under heavy tree coverage may see algae return sooner. The cleaning solution I apply has a residual effect that slows regrowth for months after the treatment.
Can you clean a metal roof?
Yes. Metal roofs don't get the same algae streaking that shingles do, but they can accumulate mold, mildew, pollen staining, and rust streaks from fasteners over time. I adjust the approach for metal — lower pressure and a milder cleaning solution — to avoid any risk to the surface finish or coatings.
What time of year is best to clean a roof?
Spring and fall are both good. Spring cleaning removes the algae that developed during wet winter months before it spreads further in summer heat. Fall cleaning removes the summer's growth before winter sets in. I can clean any time temperatures are above 40°F — our local climate generally allows roof cleaning 9–10 months of the year.
Will roof cleaning damage my gutters?
No. I work from the roof down and the rinse flows in the natural direction. The gutters may catch some residue from the cleaning process, which I rinse out at the end. I also check gutter condition during the job and will let you know if I see anything that needs attention.
