Keeping your commercial roof in top-notch condition is crucial for maintaining your property’s value and ensuring it withstands New Jersey’s diverse weather patterns. Whether it’s combating harsh winters, humid summers, or the occasional storm, understanding how to clean a commercial roof is essential. This guide provides actionable insights into the process, benefits, and considerations of commercial roof cleaning in New Jersey.

Why Is Cleaning Your Commercial Roof Important?
A clean roof is more than just about appearances. Regular maintenance can:
- Extend Lifespan: Dirt, debris, algae, and moss can degrade roofing materials over time. Cleaning removes these harmful elements.
- Prevent Structural Damage: Clogged gutters or accumulated debris can lead to water pooling and leaks, potentially causing damage to the underlying structure.
- Improve Energy Efficiency: Clean roofs reflect sunlight better, reducing heat absorption and lowering energy costs—a key factor during New Jersey’s hot summers.
- Maintain Compliance: In New Jersey, local ordinances may require businesses to adhere to maintenance standards, including roof upkeep, to avoid fines or penalties.
Steps to Clean a Commercial Roof
Here’s a step-by-step breakdown of how professionals clean a commercial roof:
1. Conduct an Inspection
Before cleaning, it’s vital to assess the roof’s condition. Inspect for leaks, damage, and the type of debris present. In New Jersey, roofs are often subjected to seasonal leaf buildup, so special attention is needed in autumn. For professional work, see CJ Commercial Roofing NJ.
2. Choose the Right Cleaning Method
Commercial roofs in New Jersey vary widely in material, from TPO and EPDM to metal or asphalt. The cleaning method depends on the material:
- Soft Washing: Ideal for delicate surfaces like single-ply membranes. A mixture of water and eco-friendly detergents is applied to remove dirt and algae without damaging the material.
- Pressure Washing: Used for durable surfaces like metal roofs, ensuring moss, mildew, and grime are effectively cleared.
- Manual Cleaning: For sensitive areas, hand tools and non-abrasive materials can ensure thorough cleaning without damage.
3. Remove Debris
Start by removing larger debris, such as branches, leaves, and dirt. This step is especially critical for businesses located near New Jersey’s wooded areas or in urban centers prone to pollution buildup.
4. Apply Cleaning Solutions
Apply the appropriate cleaning solution evenly across the roof. In New Jersey, where mold and mildew are common due to the state’s humidity levels, solutions with anti-fungal properties can be highly effective.
5. Rinse and Inspect Again
Thoroughly rinse off the cleaning solution with water, ensuring no residue is left behind. Afterward, inspect the roof for missed spots or signs of damage that require repairs.
Common Challenges in Commercial Roof Cleaning
Businesses in New Jersey often encounter unique challenges when cleaning their roofs, such as:
- Seasonal Variations: Heavy snow in winter and falling leaves in autumn can lead to clogged gutters and debris buildup.
- Urban Pollution: Industrial areas in cities like Newark or Trenton may experience more soot and grime accumulation, requiring frequent cleaning.
- Strict Regulations: Some New Jersey towns have ordinances against using certain chemicals, so always confirm compliance with local rules.
DIY vs. Professional Roof Cleaning
While DIY cleaning might seem cost-effective, hiring professionals is often the safer and more effective choice for commercial properties. Here’s why:
- Safety: Professionals are equipped with safety gear to navigate roofs safely, reducing the risk of accidents.
- Expertise: They understand New Jersey’s weather patterns and how they impact roof conditions, ensuring thorough and tailored cleaning.
- Time-Saving: Cleaning a commercial roof can be time-intensive, and professionals can complete the job efficiently.

Frequency of Commercial Roof Cleaning
The frequency of roof cleaning depends on factors like the type of roofing material, location, and surrounding environment. For New Jersey businesses:
- Urban Areas: Buildings in cities like Jersey City or Hoboken may require more frequent cleaning due to pollution and bird droppings.
- Suburban and Rural Areas: Properties near forests or open fields may experience debris accumulation during specific seasons and require bi-annual cleaning.
- Flat Roofs: These roofs may need cleaning every three to six months to prevent water pooling and algae growth.
Cost of Commercial Roof Cleaning in New Jersey
