Constructing a new roof or replacing an aging, failing structure is one of the most critical investments you will ever make in your property. In Galway, a roof must do far more than look good—it has to act as a resilient shield against the harsh Atlantic climate.
From driving rainstorms and gale-force wind gusts in coastal areas like Salthill, Spiddal, and Connemara to persistent winter downpours across Galway City, your roof requires structural integrity engineered specifically for the West of Ireland.
At Shamrock Roofing & Guttering, Desmond Sweeney and his certified team bring over 15 years of expert craftsmanship to every new roof installation. Whether you are building a custom home, undertaking a residential extension, or completely replacing a deteriorated slate or tiled roof, we manage the entire project from timber framing to the final ridge cap.
Using only heavy-duty Irish and European materials, we build roofs designed to withstand decades of extreme weather while fully complying with modern Irish building regulations and ventilation standards.
We take total ownership of your roofing project, ensuring seamless execution, clear communication, and zero stress. Every complete re-roofing project executed by Desmond Sweeney includes:
Full Removal & Disposal of Old Roofing: Safe stripping of old slates, tiles, rotted battens, and degraded felt, followed by responsible eco-friendly waste disposal.
Structural Timber Inspection & Reinforcement: Thorough evaluation of rafters, joists, and wall plates. We replace rotted timber sections and reinforce structural framing where needed to support new tile loads.
High-Performance Breathable Underlay: Installation of heavy-duty, vapour-permeable roof membrane to ensure secondary waterproofing while allowing moisture trapped inside your attic to escape.
Treated Counter-Battens & Timber Fixings: Precision installation of pressure-treated timber battens aligned for maximum ventilation and tile anchorage.
Premium Slate or Concrete Tile Fitting: Expert lay of your chosen roofing surface—from traditional natural slate to modern interlocking concrete tiles—secured with storm-rated fixings.
Leadwork & Valley Flashings: Custom code-molded lead aprons around chimneys, dormers, sidewalls, and recessed valleys to guarantee watertight joints.
Dry Ridge & Dry Verge Systems: Modern, mortar-free mechanical fixing systems along roof peaks and gables that eliminate crumbling mortar and resist wind lift permanently.
Eave Protection & Roof Ventilation: Continuous airflow systems installed at the eaves and ridge to stop attic condensation, timber rot, and mould growth.
Complete Roofline Integration: Seamless fitting or upgrading of uPVC fascia, soffit, and seamless guttering to complete your drainage system.
Choosing the right material is essential for balancing aesthetic appeal, structural weight, and weather resistance. Desmond Sweeney will guide you through the best material choices for your property:
