Single Ply Roofing Systems for Commercial & Residential Projects
Single-ply roofing systems are one of the most widely used flat roofing solutions in Ireland due to their reliability, speed of installation, and long-term performance. These systems use a single waterproof membrane to protect buildings from water ingress, wind, and weather exposure.
QBM supplies a full range of single-ply roofing systems across Ireland, including EPDM, TPO, and PVC membranes. Each option offers different performance benefits, making them suitable for commercial, industrial, and residential flat roofing applications. Choosing the right system depends on the building type, budget, and exposure conditions.
EPDM membranes are known for their durability and cost-effectiveness, making them a popular choice for residential and light commercial projects. TPO membranes offer reflective properties that help improve energy efficiency, particularly on larger commercial roofs. PVC membranes provide excellent chemical and fire resistance, making them ideal for industrial buildings and environments with higher performance demands.
Single-ply systems can be installed using fully adhered, mechanically fastened, or ballasted methods. This flexibility allows the system to be tailored to wind exposure, roof design, and structural requirements. When correctly specified and installed, single ply roofing delivers predictable performance backed by manufacturer warranties.
At QBM, our role is to support our local contractors, architects, and specifiers with technical guidance, product selection, and training to ensure each system performs as intended in Irish conditions. Get in touch with us today.

How long does it take to install single-ply roofing on a typical commercial building?
Installation duration for single-ply roofing systems varies based on roof size, complexity, weather conditions, and the chosen attachment method. A standard 1,000 square metre commercial roof typically requires 3-7 working days for experienced crews, including substrate preparation, insulation installation, and membrane application. Fully adhered systems generally take longer than mechanically fastened methods. Complex geometries with multiple penetrations, parapets, and transitions extend timelines. Weather significantly affects scheduling, wind and rain halt installation, particularly for mechanically fastened applications. Project planning should include buffer time for weather delays.
Can single-ply membranes be installed over existing roofing?
Yes, single-ply membranes can be installed over existing roofing systems in many situations, subject to structural capacity verification and substrate condition assessment. This overlay approach avoids tear-off costs and waste disposal whilst potentially improving insulation values. However, wet or deteriorated existing roofing must be removed to prevent trapped moisture issues. Building regulations may restrict the number of roof layers permitted. Engineers should verify that additional weight from new materials, insulation, and attachment systems stays within structural design limits. Our technical team assesses existing conditions and recommends appropriate approaches.
What warranty coverage comes with single-ply roofing systems?
Single-ply roofing warranties vary by manufacturer, system type, and installation quality, typically ranging from 10 to 30 years, depending on the specification and contractor certification status. Material warranties cover manufacturing defects, whilst system warranties may include installation workmanship when installed by approved contractors. Warranty terms specify maintenance requirements, inspection schedules, and exclusions that could void coverage. Extended warranties often require specific attachment methods, insulation types, and accessory products from approved manufacturers. QBM provides comprehensive warranty documentation and helps contractors understand certification requirements to maximise coverage options.
