How Delaware City’s Industrial Legacy Creates Unique Roofing Challenges for Homeowners

Delaware City’s position along the Delaware River has made it a hub for industrial activity for decades, but this industrial legacy comes with hidden costs for local homeowners. Industrial sites along the Delaware River and Delaware Bay, particularly on the outskirts of Delaware City and along the Route 9 corridor, have been key sources of significant air, land and water pollution. The refinery occupies more than 5,000 acres of land, making it one of the largest industrial facilities in North America. Understanding how this industrial pollution affects your roof materials and maintenance needs is crucial for protecting your home investment.

The Industrial Pollution Challenge in Delaware City

A hazardous air pollutant has been leaking from the Delaware City Refinery for several days. Early Monday morning, an alert sent through Delaware’s Environmental Release Notification System described a “mechanical issue” that started late Sunday night, causing the release of several chemicals into the air, including carbon monoxide, ammonia, hydrogen sulfide, sulfur dioxide and hydrogen cyanide. These chemical releases aren’t isolated incidents—they represent an ongoing environmental challenge that directly impacts building materials in the area.

From the late 1980s into the mid-2000s, state environmental regulators issued over two dozen violation notices to the company, including for emitting excess amounts of chlorine gas into the atmosphere. In 2002, Occidental ranked 16th in the nation for onsite mercury releases. Around that time, the company was also the state’s leading mercury polluter. This history of chemical emissions has created a unique environment where traditional roofing materials face accelerated degradation.

How Chemical Pollution Damages Roof Materials

Acid rain forms when pollutants like sulphur dioxide (SO₂) and nitrogen oxides (NOx) are released into the atmosphere and react with water vapour. These reactions create sulphuric and nitric acids, which then fall as precipitation with a lower pH, making the rain more acidic than normal. Aside from the usual rainfall, acid rain is particularly concerning because its acidic nature can accelerate the breakdown of certain materials, including some metals.

Acid rain can corrode your metal roof by speeding up the natural corrosion process. The acids in the rainwater, such as sulphuric acid, react with the surface of the metal, especially where protective coatings have worn thin. This reaction can strip away any remaining protective layers, exposing the metal underneath to moisture and air, which accelerates rust formation.

The impact extends beyond just metal roofing. Several roofing materials released relevant amounts of hazardous substances impacting water quality. Clay tiles are a source of vanadium, manganese, and arsenic. Treated wood shingles release ammonium, boron, copper, and Bisphenol A. When these materials are exposed to the chemical-laden environment around Delaware City, the degradation process accelerates significantly.

Specific Maintenance Challenges for Delaware City Homeowners

Rain, snow, and humidity provide the perfect environment for oxidation—the chemical process that leads to corrosion. This process is particularly dangerous because it often starts slowly and goes unnoticed, but over time, it can degrade the roof’s structural integrity. Even small puddles from melted snow or light rainfall that don’t drain properly can lead to corrosion, especially in areas where water tends to pool.

In Delaware City’s industrial environment, homeowners should pay particular attention to:

• Accelerated coating breakdown: Over time, this leads to pitting, a form of localized corrosion where small holes appear in the metal. Pitting is particularly dangerous because it can weaken specific areas of the metal roof, making it more prone to damage and leaks.
• Chemical residue accumulation: Industrial emissions can leave chemical deposits on roofing surfaces that require more frequent cleaning
• Faster deterioration of sealants and flashing: Chemical exposure can break down protective barriers more quickly than in non-industrial areas

Enhanced Maintenance Strategies

Consistent maintenance mitigates acid rain damage. Power wash exterior surfaces at least once a year to remove acidic residues. For stone surfaces, use a pH-neutral cleaner to avoid further damage. For Delaware City homeowners, this maintenance schedule should be even more frequent due to the higher concentration of industrial pollutants.
