Harmer Detail Roof Outlets are designed to cover all the awkward detailing situations that occur in building design and refurbishment. The range includes balcony, gulley and car park outlets and two way outlets for use where the roof surface abuts a wall or parapet. Harmer Rainwater Outlets Harmer Detail Roof Outlets are designed to cover all the awkward detailing situations that occur in building design and refurbishment. The range includes balcony, gulley and car park outlets and two way outlets for use where the roof surface abuts a wall or parapet. < Back Next > Harmer Roof AV Vertical rainwater outlets are designed for use with flat roof structures using either insitu cast concrete, timber or lightweight metal deck construction. Harmer Roof outlets are ideal for connection to continuous waterproofing systems using single ply membranes, mastic asphalt, high performance built-up felt, hot melt systems and wet-applied systems. Harmer Aluminium Roof Outlets Download Frequently Asked Questions Which roof constructions can use Harmer AV outlets? Harmer AV vertical outlets are intended for flat roofs formed on in-situ concrete, timber or lightweight metal decks. The outlet body, extension, connection and support detail must match the roof construction and insulation depth. Which waterproofing systems can connect to Harmer outlets? Harmer publishes options for continuous waterproofing systems including single-ply membranes, high-performance built-up felt, mastic asphalt and liquid-applied waterproofing. The correct clamping, flange or bonding arrangement must be selected for the membrane. When is a Harmer Detail outlet required? Detail outlets address balconies, gullies, car parks, parapet abutments, two-way drainage and other locations where a standard vertical outlet may not suit the geometry. The designer should select the outlet from the actual drainage and interface detail. Why are many Harmer outlets made from aluminium? Harmer uses cast aluminium to provide a lightweight, durable and corrosion-resistant outlet body. Published life expectancy varies with rural, industrial and marine exposure, and compatible gunmetal options may be required where copper or lead is present. How is the correct outlet size selected? Outlet size and quantity should be calculated from the design rainfall intensity, effective roof area, permitted head of water, outlet performance and emergency-overflow strategy. Product compatibility alone does not confirm compliance with the drainage design.

Everything ships from our Baldoyle warehouse in Kerry, 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 Kerry. 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.

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 Kerry from Our Baldoyle Warehouse We ship our roofing products across Kerry 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 Kerry. Contractors, builders, and specifiers working in Kerry 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 Kerry-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 Kerry, 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 Kerry hub .

We stock, supply and deliver a wide range of roofing materials and products to all local customers in Kerry. Can QBM recommend a roofing contractor in Kerry? 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 Kerry 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 Kerry? 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. Request a Quote or Speak to Our Technical Team If you have an upcoming or ongoing project and are looking to request a quote or speak to our technical team about the right specification for your job, call us on 01 839 117 and send us an email at info@qbm.ie .

You need materials that actually work, advice you can trust, and, perhaps most importantly, stock that's available when you need it. QBM's trade counter at Baldoyle Industrial Estate has been serving Dublin's roofing professionals since 2012, and there's a reason contractors keep coming back. Our Opening Hours & Location Monday to Thursday: 7:00 AM – 5:00 PM Friday: 7:00 AM – 4:00 PM Location: Baldoyle Industrial Estate, Dublin 13 Early access works well for contractors collecting materials before the site opens.

Our Baldoyle facility sits right in Dublin 13, easily accessible from the M50 and M1. Early starts? We're open from 7:00 AM Monday to Friday, so you can collect materials before heading to site.

Some projects demand specific solutions based on substrate type, budget constraints, or access limitations. Our technical team helps you match the right product to your actual requirements rather than just pushing whatever's on promotion.

Our technical design team reviews your project drawings, suggests solutions, and calculates precise material quantities. This service is completely free, by the way. It prevents the frustrating situation of missing a critical component halfway through installation. On-Site Profiling Service We run an in-house profiling service for hard-metal standing-seam systems. Custom flashings and cappings get pressed to your exact specifications. No waiting weeks for special orders, we handle it right here in Dublin. On-Site Training Installing roofing systems properly requires skill.

Perhaps you're working with a new membrane system or need to master complex detailing? These sessions save time and materials on actual jobs. Why Stock Quality Matters in Irish Weather Irish weather is brutal on roofs. Constant rain, wind-driven moisture, and temperature swings demand materials engineered for these conditions. Cheap imports might work fine in drier climates but fail spectacularly here. Every product we stock has proven performance in Irish conditions. Our suppliers provide proper warranties, not the vague "guarantees" that disappear when problems occur. Technical support continues after purchase because successful installations protect everyone's reputation. Who We Serve Roofing Contractor Trade accounts available with competitive pricing. Regular customers benefit from account terms that help manage cash flow across multiple projects. Our technical team provides on-site support when installations get complicated. Architects & Specifiers Looking for CPD courses or product specifications? Our team delivers presentations at your office or our facility. We work with you during the design phase to ensure specified systems meet performance requirements and budget constraints. Builders & General Contractor Not every builder specialises in flat roofing. That's fine. We guide you through product selection, calculate quantities, and explain installation requirements. Building control documentation? We provide all necessary certifications and technical data sheets. DIY & Homeowners Tackling your own flat roof project? Brave choice. We sell to DIY customers and provide the same technical advice available to professionals. Some systems are genuinely achievable for competent DIYers, though we'll be honest if you're attempting something better left to specialists.

RubberGard EPDM is a synthetic rubber single-ply waterproofing membrane for flat and low slope roofs of commercial, industrial and residential buildings. It offers outstanding durability, resilience and adaptability to current and future building needs. Elevate RubberGard EPDM - EPDM SA RubberGard EPDM is a synthetic rubber single-ply waterproofing membrane for flat and low slope roofs of commercial, industrial and residential buildings. It offers outstanding durability, resilience and adaptability to current and future building needs. < Back Next > The waterproofing market has been changing during the past few decades, with single-ply roofing membranes steadily gaining market share. Product durability, ease of application and ability to optimize the energy efficiency of buildings while minimizing their environmental impact are key factors behind this trend. RubberGard EPDM roofing membrane ticks all these boxes. RubberGard EPDM is a synthetic rubber single-ply waterproofing membrane for flat and low slope roofs of commercial, industrial and residential buildings. It offers outstanding durability, resilience and adaptability to current and future building needs. Unlike other traditional roofing membranes on the market, the installation of RubberGard EPDM is flame-free, making onsite working conditions safer. Being a single-ply membrane, it offers a lightweight roofing solution that is quick and easy to install. Features and Benefits Superior durability and longevity Total peace of mind for a very long time, that is what the RubberGard EPDM roofing membrane has to offer. Properly formulated EPDM membranes show an unmatched resistance to ozone, UV radiation and extreme temperatures. As they do not contain any plasticizers or flame retardants, their characteristics remain stable and unchanged over time. Studies show that EPDM roofing membranes have a life expectancy of more than 50 years. Quick and easy installation The RubberGard EPDM roofing membrane is easy to install. It is available in large seamless sheets up to 15.25 m wide x 61 m long (930 m²), resulting in fewer field seams needed for large surfaces and a shorter installation time. Elevate’s QuickSeam tape technology offers a proven field seaming solution without requiring sophisticated or costly equipment. High flexibility and elongation RubberGard EPDM remains highly flexible, even at temperatures as low as -45°C, enabling year-round installation. The membrane can also elongate over 300% to accommodate building movements and temperature fluctuations. Low-life cycle cost RubberGard EPDM requires little or no maintenance. If needed, it can be easily repaired using Elevate QuickSeam products, even after decades of service. This feature, combined with its inherent durability and competitive installation costs, result in a very low life-cycle cost. Sustainable roofing solution RubberGard EPDM supports your sustainable efforts. It is an inert material with a low environmental impact. No toxic substances are released during or after its installation, allowing the collection of run-off rainwater for domestic use. RubberGard EPDM can also be recycled and re-used. Elevate’s EPDM manufacturing facilities have received the ISO 14001 certification, a testimony of the company’s commitment to environmental management. Compatible with green roofs and photovoltaic installations Having successfully passed the EN 1394 test for resistance to root penetration on extensive green roofs, the RubberGard EPDM roofing membrane is ideal for extensive green roof systems that use lightweight, low-maintenance sedum vegetation. You can also easily combine RuberGard EDPM with any type of PV (photovoltaic) installation thanks to its high-temperature resistance, wear and tear resistance, and unmatched life expectancy. Choosing the Right Roofing System Are you planning to install a new roof or refurbish an existing roof? Do you want an accessible or non-accessible roof, a green roof, a roof with solar panels, a blue roof…? RubberGard EPDM roofing systems offer a variety of installation options to best meet the requirements of your project. Mechanically Attached (RMA) System Lightweight, non-penetrating mechanically attached system developed around Elevate’s QuickSeam RMA strip. The QuickSeam RMA strips are laid over the substrate and mechanically secured to the roof deck. The membrane is then adhered to these self-adhesive strips. Fully Adhered System The membrane is fully adhered directly to the substrate using Elevate bonding adhesive. Ballasted System The membrane is loosely laid over the substrate and held in place using approved ballast. RubberGard EPDM Brochure Download RubberGard EPDM Data Sheet Download RubberGard EPDM MSDS Download RubberGard EPDM SA Brochure Download Frequently Asked Questions What installation options are available for RubberGard? Standard RubberGard EPDM can form part of fully adhered, mechanically attached RMA and ballasted systems. RubberGard EPDM SA is a separate factory self-adhered product with Secure Bond adhesive. The selected system must match the deck, insulation, wind-uplift design and project approval. What is different about RubberGard EPDM SA? EPDM SA has a factory-applied adhesive across the back of the membrane, reducing on-site adhesive application and waiting time. The receiving substrate must still be clean, dry, smooth, compatible and prepared in accordance with Elevate guidance. Can RubberGard be installed in cold conditions? The standard membrane remains flexible at very low temperatures, but installation limits depend on the adhesive, primer, tape and substrate. Elevate states that EPDM SA can form a bond at temperatures as low as approximately -7°C, subject to the full application instructions. How do large sheet sizes benefit commercial roofs? Standard RubberGard is available from the manufacturer in large sheets up to 15.25 m by 61 m, reducing the amount of field seaming on suitable open roof areas. Handling, lifting, wind conditions and roof geometry must be considered when selecting sheet size. Can RubberGard be used below a green roof? RubberGard has documented resistance to root penetration for suitable extensive green-roof systems. The complete build-up must also include protection, drainage, growing media, inspection zones and structural verification, and must comply with the project warranty requirements.

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.

Protect Your Investment with Ireland's Leading Liquid Waterproofing Solutions When it comes to safeguarding your building against Ireland's unpredictable weather, liquid waterproofing systems deliver unmatched protection and longevity. At QBM, we supply premium liquid-applied membranes that form seamless, durable barriers across flat roofs, balconies, walkways, and gutters. Unlike traditional sheet membranes, liquid systems eliminate joints and seams where water typically finds its way through, creating a completely watertight envelope that moves with your structure. Our range of liquid waterproofing systems offers versatility that sheet materials simply cannot match. Whether you're working on new construction or refurbishing an existing property, these advanced formulations can be applied directly to various substrates, including concrete, asphalt, metal, and timber. The cold-applied nature of many systems means safer application conditions for contractors, with no naked flames or hot works required. This makes them particularly suitable for occupied buildings, sensitive environments, and projects where health and safety considerations are paramount. The technical performance of modern liquid waterproofing systems has transformed how the industry approaches roof protection. Products like Ultraflex, Polyroof, and Mariseal Detail provide exceptional resistance to UV degradation, thermal cycling, and standing water whilst maintaining flexibility throughout their service life. These systems typically cure to form a tough, elastomeric membrane that can accommodate structural movement and thermal expansion without cracking or splitting. Many formulations are also suitable for application in cooler temperatures, extending the working season for Irish contractors beyond the constraints of traditional systems. One of the most compelling advantages of liquid waterproofing is the speed and efficiency of installation. A competent contractor can apply these systems using standard rollers or spray equipment, dramatically reducing labour time compared to torch-on felt or adhered sheet systems. The ability to achieve a full cure within hours rather than days means buildings can return to service quickly, minimising disruption for occupants. Additionally, the self-levelling properties of liquid membranes ensure consistent coverage across complex details, upstands, and penetrations where traditional materials struggle to achieve proper adhesion. QBM maintains comprehensive stocks of liquid waterproofing systems from the industry's most trusted manufacturers, backed by technical support and warranty options that give specifiers and contractors complete confidence. Our Dublin trade counter provides immediate access to materials, whilst our technical team can assist with system selection, coverage calculations, and application guidance. Whether you're a roofing contractor seeking reliable materials for your next project or an architect specifying long-term protection for a commercial development, QBM delivers the products and expertise you need to get waterproofing right the first time. Got a Question? Find the Answer Here What surfaces can liquid waterproofing systems be applied to? Liquid waterproofing systems can be applied to a wide range of substrates, including concrete, asphalt, bitumen felt, metal decking, marine plywood, and existing weathered membranes. The surface must be clean, dry, and properly primed according to the manufacturer's specifications. Different systems are formulated for specific substrates, so it's important to select the appropriate product for your particular roof construction. How long does liquid waterproofing last compared to traditional felt systems? High-quality liquid waterproofing systems typically offer superior longevity compared to traditional torch-on felt, with many products carrying 20-25 year warranties when installed correctly. The seamless nature of liquid membranes eliminates the weak points found in sheet systems, whilst modern polymer formulations resist UV degradation and thermal cycling more effectively than older bituminous products. Regular maintenance inspections can extend service life even further. Can liquid waterproofing systems be applied in cold weather? Many modern liquid waterproofing formulations are designed for application in temperatures as low as 5°C, making them suitable for year-round installation in Ireland's climate. However, substrate conditions are critical – surfaces must be dry and frost-free. Some systems offer cold-weather variants or accelerated cure options specifically developed for lower temperature applications. Always consult the technical data sheet for specific temperature requirements of your chosen system. Are liquid waterproofing systems suitable for roofs with foot traffic? Yes, many liquid waterproofing systems are specifically designed to withstand regular foot traffic and can be specified for balconies, walkways, and accessible roof areas. Some products require a protective wearing course or aggregate finish to enhance slip resistance and abrasion resistance. For areas with intensive foot traffic or vehicular access, specialist heavy-duty systems are available that incorporate reinforcement layers for additional durability. What maintenance do liquid waterproofing systems require? Liquid waterproofing systems require minimal maintenance compared to traditional roofing materials. We recommend annual inspections to check for debris accumulation, clear drainage outlets, and inspect joints and upstands. Any minor damage or punctures can typically be repaired using the same liquid membrane material, making maintenance straightforward and cost-effective. Many manufacturers offer maintenance contracts and inspection services to protect warranty coverage and maximise system lifespan. Looking for Your Ideal Roofing Product? Get in Touch with Us Today.
