Peak Roofing and Building delivers commercial roofing services to property managers, building managers, business owners and landlords across Dún Laoghaire. We handle everything from emergency flat roof repairs on commercial units and industrial buildings to planned maintenance programmes, full roof replacements and written condition reports for insurance, lease renewals or property transactions. All work is carried out to a commercial specification with full documentation, clean and tidy sites, and minimum disruption to building occupants and business operations.

We carry out commercial roofing work throughout Dún Laoghaire, covering office buildings, retail units, warehouse and industrial properties, apartment blocks, mixed-use developments and managed commercial estates. Commercial flat roofs — whether EPDM rubber, fibreglass (GRP), built-up felt or traditional asphalt — have a finite service life, and planned maintenance is significantly more cost-effective than reactive emergency repair. We offer free roof condition surveys across Dún Laoghaire with full written reports and photographic documentation, suitable for lease renewals, insurance submissions, planned maintenance budgets and dilapidations assessments.

Areas we cover in Dún Laoghaire: Glenageary Road, Corrig Avenue, Tivoli Road, Upper Glenageary Road, Clarence Street and Myrtle Square
