Gutter Repairs Blanchardstown

A leaking or overflowing gutter does far more than create an annoying drip outside your window. When rainwater spills unchecked over your eaves in West Dublin, it tracks backward into the timber fascia boards, penetrates external cavity walls, and can steadily undermine property footings.

Blanchardstown is one of Dublin’s largest and most varied residential districts, encompassing everything from established 1970s and 1980s estates to high-density Celtic Tiger developments.

At AD Roofing, Augustine Doherty and our team provide permanent, structural gutter repairs and roofline overhauls across D15. We don’t just clear away surface leaves—we diagnose why your system failed, reset drainage falls, replace worn union seals, and install heavy-duty roofline components designed to withstand Irish weather.

Because Blanchardstown expanded rapidly across different building eras, roofline issues usually follow the construction style of your specific neighbourhood:

• Rotting Timber Fascia Boards (Hartstown, Huntstown, Coolmine, Whitestown):

  Many houses built throughout the late 1970s and 1980s still feature their original soft-timber fascia boards. Decades of minor overflow cause water to soak into the wood behind the gutter. As the timber softens with wet rot, the screws holding the gutter brackets pull free under the weight of winter rainfall, causing long sections to sag visibly.

• Perished Union Joints & Plastic Warping (Waterville, Annfield, Tyrellstown):

  The rapid build boom of the late 1990s and 2000s relied heavily on standard domestic uPVC systems. After 20 years of intense summer UV exposure followed by winter frost, internal rubber gasket seals dry out and crack. Water leaks directly through the joints, dripping onto front doorways and driveways.

• Heavy Moss Compaction on Shaded Concrete Tiles (Mountview, Fortlawn, Corduff):

  Many Blanchardstown homes feature standard concrete interlocking tiles that harbor heavy moss growth on north-facing pitches. During heavy rainstorms, clumps of wet moss wash straight down the roof and settle in the gutter channel. This debris acts like a dam at downpipe outlets, causing gutters to overflow along their entire length.

• Continuous Terraced Roofline Drainage Issues:

  In terraced layouts, gutter runs often span continuously across multiple homes. If a neighbouring gutter sags or becomes blocked, water flows back across your property line, overloading your downpipes and spilling over front walls.

We never rely on temporary tubes of silicone mastic that degrade within weeks. Every gutter repair we carry out is a permanent mechanical fix:

• Gutter Joint Resealing & Replacement: We strip out broken or leaking union brackets, clean the channel contact points, and install new heavy-duty union clips with durable, UV-stable EPDM rubber seals.

• Fall Realignment & Heavy-Duty Re-Bracketing: If water pools in the centre of your gutter run, we re-pitch the entire line using string levels to ensure a continuous fall toward the downpipe. We secure the line with heavy-duty fascia brackets spaced closely to bear heavy rainwater and moss loads.

• Deep-Flow High-Capacity Upgrades: Standard half-round gutters frequently overflow during severe West Dublin thunderstorms. We install deep-flow and ogee-profile uPVC systems capable of carrying significantly higher water volumes away from large roof pitches.

• Complete uPVC Fascia, Soffit & Gutter Replacement: We remove rotted, peeling timber entirely down to the structural rafter feet. We then install solid 18mm marine-grade uPVC fascia boards and vented soffits that prevent attic condensation and eliminate exterior painting for good.
