Industrial buildings such as warehouses and production plants are hubs of human activity. Maintenance staff, technicians, vendors and third-party agencies frequent these buildings all the time, in addition to the regular transportation of raw materials and finished goods in and out.
While maintaining clean premises is important for public image, certain areas of the building often are overlooked and not properly maintained such as the roof.
Reasons for cleaning flat roofs
Roofs of industrial buildings are vulnerable to a host of cleaning issues.
- Foliage falling from trees starts rotting and attracts insects.
- Stagnant water, snow and humidity trigger the growth of moss, mildew and fungus on the roofs. Some of them leave stains on the rooftop, which can be hard to clean normally.
- Smoke and soot from vehicle emissions or the exhaust of adjacent buildings create a layer of grime on the roofs, which cannot be cleared by a simple soap-and-scrub.
- Some rooftops of buildings are designed to reflect solar energy, and debris on the roof can make the building less energy-efficient.
- Rooftops can be made of a wide range of materials such as glass, aluminium, concrete, thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), white ethylene propylene diene terpolymer (EPDM), etc. Each of these materials has its own unique texture and surface hardness, thereby requiring different cleaning techniques.
- In industries such as Food & Beverage, compliance with Federal norms for production and clean premises is very important; else, the organization can warrant legal hassles.
- Algae, moss and rust can structurally damage the building and reduce its lifespan.
Pressure washing as a superior technique
Industries that employ traditional janitorial services have found that they are not very effective for every kind of roofing material or cleaning needs required. In the last decade or more, pressure washing has emerged as a much better alternative. The use of cold or hot water, high or moderate pressure, and mild or strong reagents makes it very effective to clean different kinds of roofs, for different cleaning needs.
Steps involved in the cleaning
- Large chunks of dirt, moss, algae, rotting vegetation and debris are scoured off, and then swept away or vacuumed as may be required. Smaller chunks are brushed out using thick-bristled brushes.
- Using the desired temperature and pressure settings, cold or hot jets of water mixed with appropriate cleaning reagents (if necessary) are used. The loosening dirt is scrubbed away and to allow for a properly maintained roof.
Rooftops are no longer an invisible or insignificant part of an industrial building. They are as vulnerable to structural damage as the rest of the building; keeping them clean is a priority from perspectives of both safety and cost.
As against in-house janitorial services, a reputed commercial cleaning company is a much better option. These companies have the experience to ensure the job is done right. All these ensure that a quality job is done on time, and within projected costs.
