A full roof replacement is a significant decision — one our roofing contractors approach with complete transparency across Castleknock. We cover all roof types: concrete and clay tiles, natural slate, and flat EPDM rubber. Where replacement is genuinely necessary — failed underlay, compromised structure, covering past its service life — we strip the existing roof, inspect and repair the timbers, install new breathable felt, and lay the new covering to current standards. A full roof replacement typically starts from €5,000 depending on roof size, design, access and materials — every job begins with a free survey and a written, guaranteed price.

Castleknock is an affluent north-west Dublin suburb with a semi-rural feel, characterised by large detached homes on mature wooded plots, quality 1980s and 1990s executive estates, and some modern new-build developments near the Phoenix Park. Properties in Castleknock are predominantly Large detached homes on mature plots along Castleknock Road, 1980s and 1990s executive semi-detached and detached estates, quality modern new-builds, and some period properties near the old village. Common roof issues we address here include natural slate deterioration on older prestige properties, lead valley failures on complex hipped rooflines, chimney repointing on larger homes, guttering blockages from mature deciduous trees, and moss accumulation on shaded north-facing pitches, making professional roofing maintenance essential for Castleknock properties. Our roofers understand the construction methods and typical materials used in Castleknock — every inspection is free and every job begins with a written quote.

From €5,000 depending on roof size and specification. Free survey and written quote always provided first. Most jobs 2–3 days.
Most full roof replacements in Castleknock are completed in 2–3 days. Larger or more complex roofs may take longer. We always confirm the expected duration in our written quote.
We carry out full roof replacements using concrete interlocking tiles, clay tiles, natural slate and man-made slate across Castleknock. We will recommend the most appropriate material for your property's age, style and budget after a free inspection.
In most cases a like-for-like roof replacement does not require planning permission. Changes to roof design, adding dormers or changing the ridge height may require consent — we will advise you during the free inspection if your planned work is likely to need planning permission.
A free inspection is the most reliable way to assess this. Common indicators for full replacement include widespread tile failure, significant batten rot, failed felt underlay across the whole roof, or a roof that is approaching or past its expected lifespan of 30–50 years. We always recommend repair where it is genuinely the right solution.
In Castleknock, the roofing problems we see most often are natural slate deterioration on older prestige properties, lead valley failures on complex hipped rooflines, chimney repointing on larger homes, guttering blockages from mature deciduous trees, and moss accumulation on shaded north-facing pitches. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
