Approvals and certifications vary by product and system. Where required for building control submissions, tender documentation, or specification work, we can supply the relevant data sheets and certification information for the specific products you are using. Delivering Across Carlow from Our Baldoyle Warehouse We ship our roofing products across Carlow and the rest of Ireland from our warehouse in Baldoyle, Dublin 13. Orders placed before midday are dispatched the same day for next working day delivery. For larger construction projects requiring multiple loads or phased deliveries, our logistics team can coordinate scheduled drops to keep your site supplied as the programme progresses. Our trade counter in Baldoyle is also open for collection if a project timeline is tight or you happen to be passing through Carlow. Contractors, builders, and specifiers working in Carlow choose to source from QBM rather than a general builders merchant for many reasons. Stock availability . One of the more frustrating parts of any construction project is waiting on materials. We hold substantial stock at our Baldoyle warehouse across the main product categories, which means fewer delays and less time spent chasing back orders. For Carlow-based contractors, that translates to materials arriving when they are supposed to. Technical support and system guidance . Our team can help with product selection, material compatibility, and full system specification. That includes advising on the right membrane for a given exposure or build-up, recommending compatible accessories, and helping you avoid the kind of mixed-system issues that cause problems later. If you are tendering or pricing a job in Carlow, we can assist with take-offs. Documentation for submissions . We can supply the data sheets, certification information, and product documentation needed for building control submissions, tender packages, and specification work. If you need something for compliance, ask us, and we will get it to you. Nationwide delivery from a single Carlow hub .

Orders confirmed before noon go out the same day for next working day arrival. Larger projects requiring coordinated or phased deliveries can be arranged through our logistics team. You can also collect from our trade counter in Baldoyle if that suits your schedule better. Where is QBM Located? QBM operates from a single warehouse and trade counter in Baldoyle, Dublin 13. We stock, supply and deliver a wide range of roofing materials and products to all local customers in Carlow. Can QBM recommend a roofing contractor in Carlow? QBM is a materials supplier and does not directly employ roofing contractors. That said, we work with installers across Ireland who are familiar with the systems we supply. If you need a steer towards experienced roofers in Carlow for a specific product, our team can usually help point you in the right direction. What roofing system is best suited for a project in Carlow? The right system depends on the building type, roof geometry, exposure, and the performance requirements of the project. EPDM rubber membranes perform well across a wide range of Irish conditions because they stay flexible and resist UV degradation. However, PVC single-ply systems are often specified for commercial buildings where particular fire or chemical resistance requirements apply. The best approach is to talk to our technical team about your specific project so we can recommend a suitable system.

Looking For Flat Roof Light Systems? QBM Stocks Rooflights, Skylights And Flat Glass Roof Windows. Quality Products Designed To Maximise Natural Daylight. Flat Roof Light Systems: Rooflights, Skylights & Roof Windows FLAT ROOFS - MEANS OF ILLUMINATION The benefits of natural illumination of buildings are unquestionable but in those with flat roofs it is not always possible to install sufficient standard vertical windows. < Back Next > Fakro Light Tunnels Fakro Flat Roof Lights Proud Stockist of: To play, press and hold the enter key. To stop, release the enter key. Premium Rooflights That Deliver Style and Performance Contemporary flat aluminium rooflights offer clean, minimal frames with large glass areas, making them ideal for modern builds and extensions where design matters as much as function. The slim profiles maximise daylight and reduce visual bulk, working particularly well in living spaces and open-plan kitchens. Most feature thermally broken frames to prevent condensation and heat loss at the frame edges, though not all budget options include this important detail. VELUX flat roof windows remain a popular choice for residential projects, combining brand recognition with proven product quality. Options include fixed units for pure daylighting and opening versions that add ventilation, with accessories such as blinds, awnings, and smoke ventilation variants available across the range. Fixed flat glass units prioritise simplicity and light transmission, making them ideal for roof skylight applications in hallways, stairwells, and other areas where ventilation isn't the primary concern. Without opening mechanisms, there are fewer components to fail over time, contributing to long-term reliability. Glass specifications vary widely, including double- or triple-glazing, tinted options, and self-cleaning coatings, providing flexibility to meet both thermal and practical requirements. Not every project needs a premium solution. Rooflite and similar products offer solid performance at more accessible price points, making them particularly common in utility areas, garages, and commercial spaces where function outweighs design considerations. These still meet relevant thermal and weather resistance standards, so budget-friendly doesn't mean compromising on the basics. Got a Question? Find the Answer Here What's the difference between a flat rooflight and a flat roof window? The terms are often used interchangeably, though "rooflight" typically refers to larger, more architectural units with minimal framing, whilst "roof window" usually describes smaller opening units like VELUX products. Both serve the same purpose of bringing natural light into spaces below flat roofs. Your choice depends on the size of the opening, whether ventilation is needed, and aesthetic preferences. Do flat roof lights need planning permission in Ireland? Most domestic flat roof light installations fall under permitted development and don't require planning permission, provided they meet certain conditions. Generally, the rooflight shouldn't protrude more than 150mm above the roof plane and shouldn't face a public road on a principal elevation. Conservation areas and protected structures have stricter rules. It's always worth checking with your local planning authority before committing to a specification. How do flat rooflights handle Irish weather conditions? Quality flat roof lights are tested to cope with wind-driven rain, standing water, and temperature extremes. Look for products with good weathertightness ratings and proper drainage channels around the frame. Installation quality matters enormously here; even excellent products can leak if fitted poorly. Thermal performance also affects condensation risk, so specifying appropriate U-values for Irish conditions helps avoid moisture problems inside. How do I prevent condensation around flat roof windows? Condensation typically occurs when warm, moist internal air meets cold surfaces. Choose rooflights with thermally broken frames to minimise cold spots at frame edges. Ensure adequate ventilation in the room, particularly in bathrooms and kitchens. Triple-glazed units offer better thermal performance than double-glazed alternatives. Proper installation with insulated kerbs also prevents thermal bridging around the opening. Can flat roof lights be installed on any flat roof? Flat roof lights can be installed on most flat or low-pitch roofs (up to 15 degrees typically), but the roof structure must be assessed first. The opening needs adequate support, and the waterproofing must be properly detailed around the unit. Some very shallow-pitch roofs may require specific products designed for minimal falls. We can advise on suitability for your particular roof type and construction. Looking for Your Ideal Roofing Product? Get in Touch with Us Today. Get in Touch

To stop, release the enter key. Flat Roof Systems with Ireland's Most Comprehensive Range of Drainage Solutions and Roofing Accessories Even the most advanced waterproofing membrane will fail catastrophically if rainwater cannot drain efficiently from the roof surface, yet drainage design remains one of the most frequently overlooked aspects of flat roof specification. QBM supplies the complete range of roof outlets, drainage accessories, and finishing components needed to create fully functional flat roof systems that shed water reliably throughout their service life. Our Roof Outlets and Accessories stock includes rainwater outlets from leading European manufacturers like b/s/t and Harmer, edge trims and drip profiles from Italprofili, expansion joints, pipe flashings, walkway systems, and specialist accessories for every flat roof configuration. Whether you're specifying drainage for a compact residential extension or designing complex multi-level commercial roof systems, we supply the technical solutions and expert guidance that ensure proper water management from the outset. The performance and longevity of roof drainage systems depend fundamentally on compatibility between outlets and waterproofing membranes, correct sizing for rainfall intensity and roof area, and appropriate detailing at critical junctions. QBM's technical team understands these interdependencies and can recommend drainage solutions matched to your specific waterproofing system, whether EPDM, PVC, liquid applied, or reinforced bitumen. Our b/s/t drainage range exemplifies best-practice design with outlets engineered for specific membrane types, incorporating integral flanges that bond directly to waterproofing layers whilst maintaining the flexibility needed to accommodate structural movement. For refurbishment projects where existing drainage proves inadequate, we supply retrofit solutions including raised outlets, sump formers, and overflow systems that upgrade performance without requiring wholesale roof reconstruction. Material compatibility extends beyond outlets to encompass every roof penetration and termination detail where waterproofing integrity must be maintained. QBM supplies comprehensive accessory ranges including prefabricated pipe flashings for soil vents and ventilation terminals, expansion joint profiles that accommodate building movement whilst preserving watertight integrity, and edge trim systems that provide professional finishing whilst protecting vulnerable membrane edges from wind uplift and UV degradation. Our Italprofili range offers particularly elegant solutions for edge details, parapet cappings, and architectural features where aesthetics matter alongside technical performance. Every accessory we supply carries appropriate certifications and manufacturer approvals for use with major waterproofing systems, eliminating the compatibility uncertainties that void warranties and generate premature failures. Beyond basic drainage and waterproofing accessories, QBM stocks a comprehensive range of ancillary components that professional roofing contractors require to deliver complete installations. Our inventory includes walkway systems and protection mats for roofs requiring maintenance access, gravel retention grids for ballasted systems, green roof drainage layers and root barriers for vegetated assemblies, and specialist sealants and adhesives for complex details. We also supply tapered insulation systems and drainage composites that create the falls needed for effective water shedding on structurally flat decks, addressing one of the most common causes of premature flat roof failure. This comprehensive approach means contractors can source complete system packages from a single supplier, streamlining procurement whilst ensuring material compatibility throughout the roof assembly. Quality Building Materials has built its reputation by maintaining the most comprehensive stock of flat roof drainage products and accessories in Ireland, eliminating the project delays associated with special orders or back-ordered components. Our Dublin trade counter provides immediate access to standard products, whilst our relationships with manufacturers enable rapid procurement of bespoke fabrications for non-standard applications. We supply complete technical data sheets, CAD details, and installation guidelines for every product line, supporting contractors and specifiers in delivering compliant installations that satisfy both Building Regulations and manufacturer warranty requirements. Whether you're a roofing contractor pricing materials for tender submission, an architect specifying drainage capacity for building control approval, or a facilities manager sourcing replacement components for maintenance works, QBM provides the products, technical expertise, and commercial terms that support successful project delivery. Got a Question? Find the Answer Here Does QBM install roof outlets and drainage systems, or only supply materials? QBM is a specialist roofing materials supplier and does not provide installation services. We supply high-quality roof outlets, drainage systems, and roofing accessories to professional contractors and roofing specialists across Ireland. Our Dublin trade counter provides expert product selection advice, technical specification support, and drainage calculations to help installers specify appropriate materials, whilst your chosen contractor handles the actual installation. This focus on supply allows us to maintain Ireland's most comprehensive stock of flat roof drainage products and provide the technical expertise that supports successful installations. How do I calculate the correct number and size of roof outlets needed for my project? Roof outlet sizing depends on several factors, including roof area, rainfall intensity for your location, drainage run lengths, and whether you're designing primary drainage only or including emergency overflow provision. As a general guide, Irish Building Regulations typically require drainage capacity based on rainfall intensity of 75mm/hour, with most residential flat roofs under 50m² adequately served by a single 70-90mm diameter outlet. Larger commercial roofs require hydraulic calculations accounting for multiple outlets, box gutters, and overflow systems. QBM's technical team can provide drainage calculations for your specific project or recommend appropriately qualified drainage engineers for complex commercial applications requiring detailed hydraulic modelling. What's the difference between primary drainage outlets and emergency overflow outlets? Primary drainage outlets handle normal rainfall and are connected to the building's rainwater drainage system. Emergency overflow outlets (also called spigot or scupper outlets) provide secondary drainage if primary outlets become blocked by debris or cannot cope with exceptional rainfall events. Irish Building Regulations require emergency overflow provision on most flat roofs to prevent structural overloading from ponded water. Overflow outlets are typically set 50mm higher than primary outlets and discharge visibly at the building perimeter, so blockages are immediately apparent. Both outlet types must be sized appropriately and detailed correctly with the waterproofing membrane to maintain watertight integrity. Are roof outlets universal, or do I need specific outlets for different waterproofing systems? Roof outlets are not universal and must be compatible with your waterproofing system to maintain watertight integrity and warranty compliance. Different membrane types require specific outlet flange configurations, bonding methods, and sealing details. For instance, EPDM outlets use rubber flanges that bond with EPDM adhesives or tape, whilst PVC outlets have welded PVC flanges, and bitumen systems use torch-applied flanges or two-part epoxy bonding systems. Using incompatible outlets is a common cause of leaks and voids manufacturer warranties. QBM supplies membrane-specific outlets from manufacturers like b/s/t and Harmer that carry approvals for major waterproofing systems, and our technical team can confirm correct outlet selection for your chosen membrane. What maintenance do roof drainage systems require to continue working effectively? Roof drainage systems require regular inspection and maintenance to ensure continued effectiveness. We recommend clearing debris from outlets and gullies at least twice annually, typically in autumn after leaf fall and in spring. Box gutters should be inspected quarterly on commercial buildings and after severe weather events. Remove all accumulated leaves, moss, and debris that could block outlets or restrict water flow. Check that outlet grilles remain secure and undamaged. Inspect overflow outlets to ensure they're clear and unobstructed. On green roofs or roofs near trees, more frequent maintenance may be necessary. Many building owners establish planned maintenance contracts with roofing specialists to ensure consistent inspection schedules and prompt clearing of blockages before water back-up causes damage.

Driving rain, high humidity, and temperature fluctuations lead to water ingress, whilst coastal areas face additional deterioration from salt-laden air. The damage isn't always immediately obvious as moisture can travel through masonry, causing spalling and surface breakdown of concrete and render, corrosion of embedded steel reinforcement, efflorescence and staining, mould growth within wall assemblies, and thermal bridging where insulation becomes saturated. Addressing these issues after they've developed costs significantly more than specifying appropriate protection from the outset, and even retrofit treatments work best when applied before significant damage occurs. Our range covers most common applications, from straightforward water-repellent treatments to complex structural waterproofing systems. Surface impregnation treatments using silane and siloxane penetrate concrete and masonry substrates, creating water-repellent barriers without blocking vapour transmission—essential for preventing trapped moisture issues. Waterproof coatings and renders form continuous barriers over surfaces, with modern elastomeric coatings capable of bridging hairline cracks and withstanding building movement. For below-ground applications and areas subject to hydrostatic pressure, we supply tanking slurries and membrane systems specifically designed to withstand demanding conditions. Different facade types require different approaches. Concrete structures need penetrating sealers, anti-carbonation coatings, or crack-bridging systems, depending on age and condition. Rendered surfaces may benefit from water repellent treatments, protective overcoating, or complete renewal with integrated waterproofing systems. Metal facades require proper detailing at joints, fixings, and interfaces, with sealants and weathering components maintaining the weather-tight envelope. Historic and heritage buildings need breathable treatments based on silicate or lime chemistry that maintain vapour permeability, working with the building rather than against it. Product selection depends on substrate type and condition, exposure conditions, performance requirements, appearance expectations, and maintenance considerations. Even the best products won't perform properly without correct application, surface preparation, weather conditions during application, and proper coverage rates, all of which affect outcomes. Modern facade waterproofing often involves external wall insulation systems where waterproofing forms part of a larger assembly, requiring careful detailing at interfaces, around windows, at corners, and where different materials meet. We stock renders, basecoats, finishing systems, beads, profiles, and sealants needed to complete these junctions properly, including products for critical roof-facade transition zones. Got a Question? Find the Answer Here How long does facade waterproofing treatment last? Durability varies considerably depending on product type, application quality, and exposure conditions. Impregnation treatments typically require renewal every 5–15 years, while coating systems may last 15–25 years before needing attention. Harsh coastal environments or heavily polluted urban areas tend to shorten these intervals. Regular inspections help identify when retreatment is needed before protection is compromised. Manufacturers provide expected service-life guidance, but real-world conditions ultimately determine actual performance. Can waterproofing be applied to damp walls? Some products tolerate residual moisture better than others, but most perform best on dry substrates. Applying water-repellent treatments to saturated masonry can trap moisture within the wall, potentially causing more severe problems than leaving it untreated. Where existing damp issues are present, it's generally advisable to identify and address the moisture source first. Certain breathable systems can be applied to walls that aren't fully dry, though this should be discussed with the product manufacturer. What's the difference between water repellent and waterproof treatments? Water-repellent treatments cause water to bead on surfaces rather than be absorbed, but they don't create a continuous barrier. They're breathable and maintain the substrate's appearance. Waterproof treatments form an impermeable film that blocks moisture movement, making them appropriate for below-ground use but potentially problematic on facades, where trapped moisture needs to escape. The distinction matters particularly for older buildings with solid walls, where breathability is often essential for long-term building health. Do waterproofing treatments affect the appearance of facades? It depends on the product. Penetrating sealers and impregnation treatments are typically designed to be invisible once cured, though they may slightly darken some substrates. Coating systems obviously change appearance, that's partly the point, and are available in various colours and textures.

Everything ships from our Baldoyle warehouse in Kildare, which is how we maintain consistent stock levels and product availability for customers right across Ireland. What Roofing Products Does QBM Supply? Our product range covers everything you may need for your next roofing project in Kildare. This includes, but is not limited to; Single Ply Membranes : EPDM rubber membranes (Elevate RubberCover) and PVC systems (FDT Rhenofol) for flat roofing on residential and commercial buildings. Reinforced Bitumen Systems : Modified bitumen membranes from Nord Bitumi, suitable for traditional flat roof construction and refurbishment. Liquid Waterproofing : Seamless liquid-applied systems for complex roof geometries where sheet membranes are difficult to detail. Standing Seam Metal Roofing : Kalzip and Vestis metal systems for pitched and architectural roofing projects. Roof Drainage and Accessories : Rainwater outlets (b/s/t and Harmer), edge trims, pipe flashings, roof vents, primers, adhesives, and sealants.

Professional Roofing Tools : Specialist hand tools by Freund, hot air welding equipment, and sheet metal folding machines for on-site fabrication. Facade Systems : Kalzip FC rainscreen facade panels and airtight membranes from Riwega. One of the practical advantages of ordering from QBM is the ability to source a complete roofing system from one supplier. Membrane, insulation, drainage, trims, adhesives, and tools all come from the same place, which helps ensure material compatibility and avoids warranty issues that can arise from mixing components from different manufacturers. Approvals and certifications vary by product and system. Where required for building control submissions, tender documentation, or specification work, we can supply the relevant data sheets and certification information for the specific products you are using. Delivering Across Kildare from Our Baldoyle Warehouse We ship our roofing products across Kildare and the rest of Ireland from our warehouse in Baldoyle, Dublin 13. Orders placed before midday are dispatched the same day for next working day delivery. For larger construction projects requiring multiple loads or phased deliveries, our logistics team can coordinate scheduled drops to keep your site supplied as the programme progresses. Our trade counter in Baldoyle is also open for collection if a project timeline is tight or you happen to be passing through Kildare. Contractors, builders, and specifiers working in Kildare choose to source from QBM rather than a general builders merchant for many reasons. Stock availability . One of the more frustrating parts of any construction project is waiting on materials. We hold substantial stock at our Baldoyle warehouse across the main product categories, which means fewer delays and less time spent chasing back orders. For Kildare-based contractors, that translates to materials arriving when they are supposed to. Technical support and system guidance . Our team can help with product selection, material compatibility, and full system specification. That includes advising on the right membrane for a given exposure or build-up, recommending compatible accessories, and helping you avoid the kind of mixed-system issues that cause problems later. If you are tendering or pricing a job in Kildare, we can assist with take-offs. Documentation for submissions . We can supply the data sheets, certification information, and product documentation needed for building control submissions, tender packages, and specification work. If you need something for compliance, ask us, and we will get it to you. Nationwide delivery from a single Kildare hub .

Frequently Asked Questions Does QBM deliver roofing materials directly to sites in Kildare? Yes. We deliver across Kildare, from our warehouse in Balydoyle, Dublin 13.

We stock, supply and deliver a wide range of roofing materials and products to all local customers in Kildare. Can QBM recommend a roofing contractor in Kildare? QBM is a materials supplier and does not directly employ roofing contractors. That said, we work with installers across Ireland who are familiar with the systems we supply. If you need a steer towards experienced roofers in Kildare for a specific product, our team can usually help point you in the right direction. What roofing system is best suited for a project in Kildare? The right system depends on the building type, roof geometry, exposure, and the performance requirements of the project. EPDM rubber membranes perform well across a wide range of Irish conditions because they stay flexible and resist UV degradation. However, PVC single-ply systems are often specified for commercial buildings where particular fire or chemical resistance requirements apply. The best approach is to talk to our technical team about your specific project so we can recommend a suitable system.

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.

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. Looking for Your Ideal Roofing Product?
