New Roofs Monkstown
Heritage Slate & Complete Roof Replacements
A complete roof replacement is a major structural undertaking for any property, but in Monkstown, it demands specialised coastal knowledge and heritage craftsmanship. Properties situated along Longford Terrace, Belgrave Square, Richmond Hill, and Albany Avenue endure punishing coastal conditions: intense wind uplift from easterly maritime gales, persistent salt dampness, and driving rain.
When an older roof reaches the end of its structural life, continuing to pay for patch repairs simply postpones the inevitable. Rusted fixing nails, rotted timber battens, perished underlay, and cracked slates allow water to keep penetrating deeper into the building, compromising roof rafters and ceiling structures.
At AD Roofing, we deliver complete, high-performance roof replacements across Monkstown. Managed and installed directly by Augustine Doherty and our experienced team, we replace failing roofs with authentic natural slate, heritage tiles, and marine-grade flat roof systems. Every complete new roof installation is backed by our 15-year written guarantee.
When Does a Monkstown Home Require a Complete Re-Roof?
Monkstown features an architectural mix of early 19th-century Regency villas, Victorian townhouses, and mid-century family homes, many of which have reached the end of their original roofline lifespan:
Widespread Nail Sickness on Victorian Slate Roofs (Belgrave Square, Longford Terrace, Richmond Hill):
Many historic homes across Monkstown 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 (Carrickbrennan, Mounttown Borders):
Homes built in the mid-20th century 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 Lead Valleys on Complex Period Rooflines:
Substantial period properties often feature complex roof designs with multiple hips, gables, dormers, and intersecting valleys where Victorian additions were joined to earlier structures. When aged lead valley channels split from thermal movement and marine salt exposure, water tracks unseen along rafters, rotting structural timber framing. Where patch fixes have failed repeatedly, stripping the flanks and re-roofing is the only permanent solution.
Failing Flat Roofs on Extensions & Rear Returns:
Monkstown features many period homes with two- and three-storey rear returns, as well as contemporary kitchen extensions with flat roofs. Traditional mineral felt flat roofs struggle with thermal expansion and standing water, typically blistering and cracking within 10 to 12 years. Upgrading to a seamless GRP fibreglass system provides permanent weatherproofing.

What Our Monkstown Roof Replacement Package Delivers
We never cut corners by overlaying old materials or skipping modern ventilation standards. Every complete roof replacement we undertake in Monkstown 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.

Frequently Asked Questions
Do I need planning permission to replace my roof in Monkstown?
In the vast majority of standard residential cases, replacing an existing pitched roof like-for-like is classified as "Exempted Development" by Dún Laoghaire-Rathdown County Council, provided you keep the original roof profile and do not alter the height or pitch. If your property is a Protected Structure or situated within an Architectural Conservation Area (such as Belgrave Square or Longford Terrace), specific heritage regulations apply regarding slate selection and leadwork detailing, which we can review during your physical survey.
Why do you specify copper or stainless-steel nails in Monkstown?
Standard galvanised nails corrode rapidly in coastal salt air, causing "nail sickness" where perfectly good slates slip down the pitch because the fixings have rusted through. We fix our natural slates using heavy-gauge copper or marine-grade stainless-steel nails that will never corrode, ensuring your roof remains intact for decades.
How long does a full roof replacement take on a period Monkstown home?
Depending on roof size, pitch complexity, and weather conditions, a complete strip and re-roof on a large period townhouse in Monkstown typically takes between 5 to 8 working days. We work in tightly managed sections to ensure your home remains completely dry and weatherproof every night of the project.
