Galway's older stone and slate houses in the city centre and surrounding townlands face constant Atlantic salt spray and high wind loads that lift tiles and crack natural slate over decades. Modern estates on the outskirts often mix concrete tiles with poor original fixings that fail faster under heavy driving rain. We match replacement materials to the original build rather than forcing a one-size approach that leads to leaks at hips and valleys.
Natural Irish slate remains the first choice for period properties because it weathers to match existing roofs, while GRP fibreglass valleys and abutments give a watertight seal where lead would corrode quickly in salt air. SEAI grants can offset costs when the work improves the BER rating, but only if insulation and ventilation are upgraded at the same time. We always check for hidden rot in rafters before quoting because damp from failed underlay is common once the old covering comes off.
Edge cases include narrow access on terraced streets and steep pitches above 45 degrees that require extra scaffolding time. Homeowners often underestimate how much the roof pitch and exposure change the fixing method; using standard clips on a wind-exposed gable leads to repeated failures within a few winters.
Technician insight
In Galway the thing that catches most people out with slate and tile replacements is how quickly salt air eats through standard fixings on roofs over thirty years old, especially on the exposed side facing the bay. Older terraced houses around the city often have hidden rafter rot once the covering is stripped, and skipping the insulation upgrade means you miss the SEAI contribution that many jobs now rely on.
Slate failure on a Claddagh terrace
Wind-driven rain had lifted several slates on a 1920s terrace house near the Claddagh. We found widespread nail corrosion and wet underlay. After full strip we fitted new Irish slate with stainless fixings and GRP valleys, then added insulation to lift the BER. The owner avoided repeated patch repairs through the next winter.
Slate & Tile Roof Replacements Services We Offer
✓Natural Slate Roof Replacement
Full strip and re-cover using Irish or Welsh slate matched to the existing roof on older Galway homes for wind and salt resistance.
✓Concrete Tile Roof Replacement
Replacement of failing concrete tiles on modern estates with heavier gauge tiles and upgraded fixings suited to Atlantic gusts.
✓GRP Valley and Abutment Installation
Installation of fibreglass valleys and wall abutments during re-roofing to prevent leaks where lead would degrade in coastal air.
✓Ridge Tile and Verge Replacement
Renewal of ridge tiles and verges with mechanical fixings and mortar that holds up to repeated high-wind events in County Galway.
✓Insulation Upgrade During Re-roof
Addition of roof insulation and ventilation upgrades at the same time as slate or tile replacement to support better BER ratings.

How it works
- 1
Site Inspection and Measurement
We measure the roof from Monivea Rd and note exposure, pitch, and any rot in rafters before preparing a written scope.
- 2
Material Selection and Quote
We select slate or tile grade and fixings based on the property's age and location, then provide a fixed quote including scaffolding.
- 3
Strip and Preparation
Old covering is removed, damaged timbers replaced, and new breathable underlay fitted with correct overlaps for driving rain.
- 4
Installation and Detailing
New slate or tiles are fixed to code, GRP valleys installed, and all ridges and verges mechanically secured.
- 5
Final Check and Handover
We walk the roof with the owner, clear all debris, and leave contact details for any follow-up within the first winter.
Pricing
Full slate and tile replacements in Galway typically fall between €8,000 and €18,000 depending on roof size, access and whether insulation is added.
