Lansing, MI Roof Cleaning: Biodegradable Soap Removes Mold for 10-15 Years
Roof cleaning in Lansing, MI using biodegradable soap removes mold, black streaks, and mildew while keeping roofs free of growth for ten to fifteen years without harsh chemicals or high pressure.
What causes black streaks and mold on roofs?
Black streaks are caused by algae that feed on limestone filler in asphalt shingles, while mold thrives in shaded, damp areas with poor airflow.
The dark discoloration you see is actually a type of blue-green algae called Gloeocapsa magma. It spreads across shingles and holds moisture against the surface. Over time, that moisture promotes mold and mildew growth, especially on north-facing slopes that stay cool and wet.
Once algae takes hold, it accelerates shingle degradation by trapping heat and breaking down protective granules. Cleaning early prevents this damage and extends roof life significantly.
How does biodegradable soap work on roofs?
Biodegradable soap breaks down organic growth at the cellular level without the need for high-pressure washing that can damage shingles.
Traditional pressure washing can strip granules, loosen sealant tabs, and force water under shingles. Soft-wash methods apply cleaning solution at low pressure, allowing it to penetrate and kill algae, mold, and mildew from the root. The solution is then rinsed gently, leaving shingles intact and clean.
This approach is safe for all roofing materials and avoids the risk of leaks or warranty voids. The biodegradable formula also breaks down naturally, so it won't harm landscaping or stormwater systems.

Can roof cleaning really last 10-15 years?
Yes, when biodegradable treatments are applied correctly, they inhibit regrowth by leaving a protective residue that discourages algae and mold colonization.
The cleaning solution not only removes existing growth but also changes the surface chemistry slightly to make it less hospitable to spores. In most cases, roofs stay visibly clean for a decade or longer, depending on exposure and local climate.
Reapplication is rarely needed unless your roof is heavily shaded by trees or located in an area with high humidity year-round. Regular inspection helps you catch any early regrowth before it spreads.
Why is roof maintenance critical in Lansing's climate?
Lansing, MI experiences high humidity in summer and freeze-thaw cycles in winter, both of which accelerate mold growth and shingle wear.
Summer humidity creates ideal conditions for algae and mold, especially after thunderstorms. Winter ice dams trap moisture under shingles, which can lead to leaks and interior damage when snow melts. Cleaning your roof before winter removes organic material that holds water and worsens ice dam formation.
Spring is the best time to inspect and clean because you can address winter damage and prepare for the humid months ahead. If you also need help with other exterior surfaces, explore power washing services in Lansing, MI to tackle driveways, patios, and walkways.
A clean roof protects your home from water damage and improves energy efficiency by reflecting more sunlight. Regular maintenance prevents expensive repairs and keeps your property looking sharp.
