New Roofs Killiney

A complete roof replacement is a major investment in your home, but in Killiney, it requires specialized structural standards. Standing exposed along the coastal contours of Killiney Hill Road, Strathmore, and Victoria Road, homes here withstand severe wind uplift, salt-air saturation, and torrential Atlantic rain.

When an aging roof reaches the end of its structural life, patch repairs become an expensive distraction. Perished bitumen underlay, nail sickness on original slates, split valley metal, and rotted timber battens will allow water to keep finding new paths into your property, quietly weakening rafters and ceiling structures.

At AD Roofing, we deliver complete, high-performance roof replacements across Killiney. Managed and installed directly by Augustine Doherty and our experienced team, we replace failing roofs with authentic natural slate, premium tiles, and marine-grade flat roof systems. Every complete new roof installation is backed by our 15-year written guarantee.

Killiney’s housing stock features grand 19th-century granite villas, mid-century hillside family homes, and modern architectural residences, many of which have reached the end of their original roofline lifespan:

• Widespread Nail Sickness on Victorian Slate Roofs (Killiney Hill, Church Road):

  Many historic homes across Killiney still feature original natural stone slates. While the slate itself can endure for over a century, the original iron or light galvanised fixing nails have long since corroded from decades of salt-air exposure. Slates continually slide out of position, leaving exposed holes that cannot be securely repaired without a complete strip and re-nail.

• Degraded Bitumen Underlay & Rotted Timber Battens (Ballinclea, Seafield, Bayview):

  Homes built in the 1960s, 70s, and 80s were installed with traditional tar-based bitumen felt under the tiles. After decades of attic heat and coastal humidity, this felt turns brittle and shreds to dust. Once wind-driven rain forces its way past aging tiles, there is no secondary waterproof barrier to protect your ceiling plasterboard.

• Failed Celtic Tiger Valleys on Complex Hillside Rooflines:

  Substantial detached properties built on hillside contours often feature complex roof designs with multiple hips, gables, dormers, and intersecting valleys. When cheap valley liners or thin lead substitutes crack along their centre fold, continuous water tracks unseen into structural timber rafters. Where patch fixes have failed repeatedly, stripping the flanks and re-roofing with modern dry-fix systems is the only permanent solution.

• Failing Flat Roofs on Contemporary Hillside Extensions:

  Killiney features many modern architect-designed homes and extensions with flat or low-pitch roofs. Traditional mineral felt flat roofs struggle with coastal temperature swings and standing water, typically blistering and cracking within 10 to 12 years. Upgrading to a seamless, marine-grade GRP fibreglass system provides permanent weatherproofing.

We never cut corners by overlaying old materials or skipping modern ventilation standards. Every complete roof replacement we undertake in Killiney includes:

• Engineered Scaffolding Setup: Safely erected and dismantled in full compliance with Irish HSA standards, designed to respect your garden, stone walls, and driveway access.

• Complete Strip-Down to Rafters: Total removal and legal disposal of old slates, tiles, rotted battens, and perished felt down to the structural timber framework.

• Structural Timber Inspection & Restoration: Augustine personally inspects every rafter, purlin, and wall plate, replacing any water-damaged timber with structural, pressure-treated wood.

• High-Performance Breathable Membrane: We install heavy-duty vapour-permeable underlay (such as Tyvek Supro) that repels driving rain and sea spray while allowing attic humidity to escape naturally.

• Treated Counter-Battens: Pressure-treated timber battens spaced with precision to guarantee correct tile overlap and structural rigidity against high coastal winds.

• Natural Slate or Premium Tile Installation: We install authentic Blue Bangor Welsh slate, high-grade Spanish slate, or premium concrete tiles, secured using non-corrosive copper or marine-grade stainless-steel nails to prevent future nail sickness.

• Maintenance-Free Dry Fix Systems: Mechanically secured dry ridge and dry verge systems that clamp edge tiles firmly against gale-force winds, eliminating cracked sand-and-cement mortar.

• Code 5 Milled Leadwork: Heavy-gauge lead hand-dressed to all chimney aprons, step flashings, roof valleys, and abutments for long-term waterproofing.

• Spotless Site Clearance: All old materials and site debris cleared into our own skips, leaving your driveway and grounds clean.

• 15-Year Written Guarantee: A direct, personal guarantee covering materials and workmanship, signed by Augustine Doherty.
