Peak Roofing and Building specialises in flat roof repairs and replacement throughout Dún Laoghaire. From garage flat roofs and rear extension roofs to parapet-enclosed flat roofs on Victorian terraces, we carry out both like-for-like felt repairs and full upgrades to modern EPDM rubber membrane. EPDM roofs carry a manufacturer's 25-year product guarantee and require minimal maintenance — they are the most cost-effective upgrade available for any flat roof in Dún Laoghaire.

Flat roofs are common on garages, rear extensions and outbuildings throughout Dún Laoghaire. Original felt flat roofs from the 1970s and 1980s have a typical lifespan of 15–25 years, meaning most are now at or past their end of life. If you are seeing blistering felt, sagging, or damp patches on the ceiling below a flat-roofed area in your Dún Laoghaire property, it is time for a replacement. We offer free flat roof surveys across Dún Laoghaire with no call-out charge.

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

"Excellent work from start to finish. I had other roofers quote and all felt the plywood was still good. James was 100% correct it had to go and be replaced. I also really liked that they supplied so many photos and vids to show the quality of the work. Gave me great assurance."

The coastal location means constant exposure to salt-laden air which accelerates the deterioration of mortar joints, natural slate nibs and metal flashings. Properties within 500 metres of the harbour particularly benefit from annual roof inspections.
