When Glass-Making Giants Leave Their Mark: How Newark’s Century of Manufacturing Creates Stubborn Roof Stains That Ordinary Cleaning Can’t Touch
Newark, Ohio’s streets tell a story of industrial ambition that spans over 150 years, but that legacy lives on in ways homeowners never expected—embedded deep in their roof shingles. What many residents don’t realize is that decades of glass manufacturing, particularly from industry giants like A.H. Heisey & Company and Holophane, have left microscopic pollutants that create unique roof cleaning challenges unlike anywhere else in Ohio.
The Glass Capital’s Hidden Legacy
Glass has been a big industry in Newark and Licking County for almost a hundred and fifty years, largely due to the amount and quality of silica that naturally occurs in the area. August H. Heisey, a German-born Pittsburgh glassmaker who married into the Duncan family of the Ripley Glass Company, founded his own glass company in 1896, finding affordable labor and abundant natural gas in Newark, Ohio. Construction of the factory at 301 Oakwood Avenue began in 1895 and it opened in April of 1896 with one sixteen-pot furnace. The factory subsequently had three furnaces and employed nearly seven hundred people.
But glass manufacturing wasn’t just about creating beautiful tableware. Lead glass manufacture may result in lead emissions of about 2–5 kg/t. In all cases, the concentration of heavy metals and other pollutants in the raw flue gas mainly depends on the type of fuel used, the composition of the feed material, and the portion of recycled glass. These emissions didn’t just disappear—they settled into the surrounding environment, including on rooftops throughout the area.
Why Newark’s Roof Pollutants Are Different
Unlike typical environmental contaminants that sit on roof surfaces, Newark’s industrial legacy has created embedded pollutants that penetrate deep into roofing materials. Refining agents include arsenic trioxide, antimony oxide, nitrates, and sulfates. Metal oxides and sulfides are used as coloring or decoloring agents. Over decades of glass production, these compounds became airborne and eventually settled on roofs throughout the area.
Glass manufacturing plants that operate one or more continuous furnaces which produce at least 45 Mg/yr (50 tpy) of glass per furnace by melting a mixture of raw materials that includes compounds of one or more of the glass manufacturing metal HAP have historically released hazardous air pollutants that create lasting contamination challenges.
The problem is compounded by the fact that wet and dry air deposition contributes to the contaminants from commercial, residential, and industrial roofs, with metals, polycyclic aromatic hydrocarbons (PAHs), phthalates, and other compounds leaching from roofing and other construction materials. In Newark, this natural process was supercharged by decades of industrial emissions.
The Challenge for Modern Roof Cleaning
Standard roof cleaning methods often fail in Newark because they’re designed for surface-level contaminants, not the embedded pollutants that characterize the area’s industrial heritage. About 0.4 tons of wastewater is produced for every ton of waste glass cleaned by hydraulic cleaning technology, leading to secondary pollution. Greener and more efficient treatment is required to remove the organic impurity of waste glass. This principle applies to roof cleaning as well—traditional methods can actually make the problem worse by driving contaminants deeper into the roofing material.
Professional roof cleaning newark services require specialized knowledge of these unique challenges. Companies that understand Newark’s industrial history can develop targeted approaches that address both surface contamination and embedded pollutants that have accumulated over generations.

The Science Behind Effective Treatment
Effective roof cleaning in Newark requires understanding the molecular structure of embedded contaminants. The temperature of desiccation furnace is generally set to 200 °C, and thermal decomposition of organic impurity above 200 °C may produce toxic and harmful substances such as dioxins. Under the continuous supply of external heat, the organic impurity was separated from the glass surfaces. This historical process means that modern cleaning must use specialized techniques to safely remove these embedded compounds without causing further damage.
For glass fabrication applications, cleanliness of the workspace is particularly critical, as even the smallest particulates can result in manufacturing errors, downtime, and costly cleanup efforts. Clean rooms serve as the perfect solution to these issues as they employ high-performance filters that collect and remove a wide range of contaminants from the work environment. While homeowners can’t create clean room conditions, professional roof cleaning services can apply similar principles to ensure thorough contaminant removal.
Long-Term Protection Strategies
Because Newark’s industrial legacy continues to affect roofing materials, regular maintenance becomes even more critical. Specialized services include shingle rejuvenation and roof rejuvenation, which breathe new life into aging roofs, extending their lifespan and enhancing their appearance. For those needing a thorough cleaning, comprehensive roof power wash effectively washes roof shingles and eliminates grime.
The key is working with professionals who understand that Newark’s roofs aren’t just dirty—they’re chemically compromised by decades of industrial activity. This requires not just cleaning, but restoration and protection strategies that account for the area’s unique environmental history.
Moving Forward: Protecting Your Investment
Newark’s industrial heritage is part of what makes the community unique, but it also creates ongoing challenges for property maintenance. Understanding these challenges is the first step toward effective roof care. Growth shaped by the arrival of the Erie Canal, a prosperous farming community, and an industrious workforce continued to grow with the arrival of companies like Holophane, Heisey and Owens Corning Fiberglass — brought here by our rich store of silica, iron, oil and glass.
Today’s homeowners benefit from this industrial legacy in many ways, but they also inherit its challenges. Professional roof cleaning services that understand Newark’s unique contamination patterns can help protect your investment while preserving the historical character that makes the area special.
