Commercial Flat Roof Repair & Waterproofing at Green Isle Hotel, Dublin 22

The Green Isle Hotel in Newlands Cross required commercial flat roof repair works following concerns around water ingress and general deterioration across sections of the roof. Large commercial roofs are exposed to constant weathering, standing water, foot traffic from maintenance teams, and movement around roof-mounted plant and service equipment. During inspection, MJ Roofing & More identified several common issues affecting the roof:

• Localised waterproofing failure around roof penetrations and service equipment
• Open or weakened areas around pipework, ventilation units and duct supports
• Previous repair patches showing signs of wear and water retention
• Ponding water in sections of the flat roof surface
• Exposed junctions around parapet walls, upstands and rooflight openings
• Loose debris and working materials affecting roof drainage and inspection access
• Areas where the existing flat roof membrane required reinforcement to prevent further leaks

On a commercial property such as a hotel, unresolved flat roof defects can quickly lead to internal water damage, ceiling staining, disruption to guest rooms, plant-room issues and higher repair costs. For this reason, a targeted commercial roof inspection and flat roof leak repair programme was carried out to address the most vulnerable sections.
