The dark staining on your roof is Gloeocapsa Magma — a resilient cyanobacteria that feeds on the limestone filler embedded in your asphalt shingles. It forms a UV-protective dark outer shell (that's the black color), which absorbs heat and destroys the Albedo effect of your roof — causing your home to retain more heat, spike your energy bills, and accelerate shingle degradation from the inside out.
Indiana's high-humidity climate creates ideal conditions for accelerated Gloeocapsa Magma colonization. What starts as faint dark lines becomes full-surface biological coverage within 2–3 seasons if left untreated.

We do NOT use high-pressure washing on roofs. High pressure destroys granules, voids warranties, and causes hydrostatic damage to your decking. Chemistry does the work — not force.
We wet down all surrounding vegetation and apply a neutralizing barrier to protect your landscaping before any chemistry is applied.
ARMA-recommended sodium hypochlorite solution is applied at under 100 PSI — letting chemistry do the work, not brute force.
We allow the biocidal solution to penetrate the Gloeocapsa Magma colonies, breaking down their UV-protective shells and eliminating the organism at the cellular level.
A thorough low-pressure rinse removes all residue. Plants are re-rinsed and neutralized to ensure zero landscaping damage.
After Gloeocapsa Magma treatment, your roof's natural solar reflectivity is fully restored. This Albedo effect restoration reduces attic temperatures, lowers HVAC load, and measurably reduces cooling costs — many clients report 20–30% attic temperature reduction within the first season post-treatment. Asphalt shingle rejuvenation isn't just cosmetic — it's a long-term energy and financial investment.
