Dún Laoghaire homeowners trust Peak Roofing for flat roofs. 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. For roofs in reasonable condition, resurfacing is often a more affordable option — from €1,500 depending on size and surface condition, most jobs completed in 1 day. Our free inspection tells you whether resurfacing or full replacement is the right fit for your Dún Laoghaire roof.

"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."

Frequently Asked Questions

From €4,200 depending on roof size, access and materials chosen. Most jobs 1–2 days. Free inspection and written quote before any work begins. If your roof is in reasonable condition, ask about resurfacing — a more affordable option from €1,500, and our free inspection will tell you which is the right fit.
EPDM rubber membrane is the most durable and cost-effective flat roof system available today. It carries a manufacturer's 25-year product guarantee, requires minimal maintenance and is significantly more durable than traditional felt. GRP fibreglass is also an excellent option, particularly for roofs with complex detailing. We will recommend the right system for your specific roof after a free inspection.
Most flat roof replacements in Dún Laoghaire are completed in 1–2 days. We always confirm the expected duration in our written quote.
A free inspection is the most reliable way to assess this. In general, blistering felt, cracking, ponding water or damp patches on the ceiling below are signs that full replacement is the right solution. If the roof structure is sound and damage is localised, a repair may extend the roof's life cost-effectively. We always recommend repair over replacement where it is genuinely the right option.
Yes. We carry out patch repairs, full re-felting and EPDM rubber replacements across Dún Laoghaire. Where a flat roof can be repaired rather than replaced, we will always recommend that option — repair is typically the more cost-effective solution where the roof structure is sound.
In Dún Laoghaire, the roofing problems we see most often are accelerated slate and mortar deterioration from coastal salt air, storm-driven rain penetration on exposed seafront properties, cracked chimney stacks on Victorian terraces, and flat roof failures on rear extensions. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
