A large industrial unit in Redhill was facing significant roof drainage issues, with gutters overflowing during rainfall due to years of moss, leaves, and debris accumulation. DrainBoss performed a complete roof and gutter clearance using specialist access equipment and high-pressure cleaning tools. All drainage channels and guttering were safely cleared, flushed, and tested to ensure full water flow. The proactive maintenance not only restored efficiency but also helped extend the roof’s lifespan — saving the client from future repair costs.
The facilities manager of a busy industrial unit in Redhill contacted DrainBoss after ongoing gutter overflows began affecting external walls and loading areas. Inspections showed that the gutters and roof gullies were heavily clogged with organic matter and silt deposits built up over several years. As the property had extensive roof drainage and multiple downpipes, the blockages had caused standing water to collect on the roof — posing both safety and structural risks.
Recognising the scale and height of the building, a tailored access plan was required to safely carry out the work without disrupting daily business operations.
DrainBoss deployed a team of experienced commercial cleaning specialists equipped with mobile elevating work platforms (MEWPs) and safety harness systems. The team began by manually removing large debris such as moss, leaves, and roof sediment before performing a full high-pressure clean of all gutter runs, roof channels, and downpipes.
Using water-fed poles and jetting attachments, the engineers flushed each section to verify full flow and remove fine silt residue. Special care was taken to ensure that outlets and gullies connected to the internal drainage system were free from obstruction.
Once the cleaning was completed, a final inspection confirmed unrestricted water flow across the entire roofline, ensuring the drainage system could handle heavy rainfall efficiently.
The project was completed on schedule and without any disruption to site operations. The client immediately noticed a dramatic improvement in rainwater discharge, with no further overflow or pooling issues. The preventative maintenance approach taken by DrainBoss also reduced the risk of roof leaks and corrosion, significantly prolonging the service life of the roofing system. The facilities manager commended the team for their professionalism, adherence to safety standards, and attention to detail throughout the project.
DrainBoss Comment: Regular roof and gutter maintenance is essential for commercial properties, especially large industrial buildings where access can be difficult. This Redhill project demonstrates how proactive cleaning prevents costly damage, improves drainage efficiency, and protects valuable assets. Our team’s methodical, safety-focused approach ensures that even complex sites are maintained to the highest professional standard.
