When you're selecting flat roofing materials for a commercial project, two names dominate the conversation: TPO and PVC. Both are single-ply thermoplastic membranes. Both create watertight roofing systems. Both reflect sunlight effectively. Yet they're remarkably different in ways that matter for long-term performance and total project cost. The choice between TPO and PVC isn't simply about matching specifications to a budget; it's about understanding which material genuinely

If you’ve been researching flat roofing options for a commercial building, you’ve probably come across PVC single-ply membranes. In Ireland, one of the most established PVC-P solutions is FDT Rhenofol—a welded, reinforced membrane system used on everything from warehouses and retail units to education and healthcare projects. But what exactly is PVC roofing, and why does it perform so well on flat and low-slope roofs? This guide explains PVC roofing in plain terms, how Rhenof

Bitumen flat roofs protect thousands of commercial and residential buildings across Ireland. They're reliable, cost-effective, and when properly maintained, can provide decades of service. Yet many property owners only think about their flat roof when something goes wrong, and by then, what could have been a simple fix has become an expensive emergency. The good news? Most bitumen flat roof problems are preventable. Regular maintenance doesn't require specialist knowledge or

Modified bitumen is one of the most widely used waterproofing systems for flat and low-slope roofs across Ireland, particularly on commercial, warehouse, and industrial buildings. It combines the proven waterproofing performance of bitumen with polymer modification to improve flexibility, durability, and resistance to cracking. If you’re comparing flat roof options, understanding how modified bitumen works (and how it’s installed) will help you choose a system that performs r

When you're budgeting for a commercial roofing project, one question matters more than almost any other: how long will this roof actually last? It's a fair question, especially given the investment involved. Nobody wants to be facing another roof replacement in just a few years. Bitumen roofing systems have protected Irish buildings for decades, but their lifespan isn't a simple number you can look up and forget about. The reality involves several variables, from material typ

You've got an EPDM rubber roof and need to access it for maintenance, gutter cleaning, or window washing. Perhaps you're even thinking about converting that flat roof into a usable balcony space. But can you actually walk on EPDM without causing damage? The straightforward answer: yes, you can walk on EPDM roofs, but there are important caveats. Light foot traffic for installation, maintenance, and occasional access is fine. Regular or heavy use requires protective modificati

You’ve decided on EPDM for your flat roof, which is a solid choice. But now comes another decision that perhaps matters more than you’d think: what membrane thickness should you choose? Many people assume thicker is always better, but that’s not necessarily true in every situation. A garden shed doesn’t need the same protection as a commercial building with regular maintenance access. Your budget matters too, because thickness directly affects cost. EPDM membranes are availab

Choosing the right flat roof material isn’t always straightforward. You’ve probably heard about EPDM, that black rubber membrane that’s become increasingly popular across Ireland, but you might be wondering whether it’s actually the right choice for your property. Maybe you’re roofing a new extension, or your existing flat roof has reached the end of its life and needs replacing. Either way, it makes sense to understand the pros and cons properly rather than choosing a system

When you're investing in a flat roof, lifespan matters. Nobody wants to replace a roof every decade. EPDM rubber roofing has built a strong reputation for longevity, but what does that mean in practical terms for Irish property owners? A realistic expectation for a properly installed EPDM roof in Ireland is 30–50 years , depending on specification, exposure, and maintenance. That’s not marketing talk, it’s supported by decades of real-world performance, with EPDM roofs instal

Replacing a flat roof forces you into a decision between competing materials. EPDM rubber roofing keeps appearing in your research, while traditional felt still covers countless roofs across Ireland. So which option actually gives better value? Both systems work, otherwise neither would still be widely used. But they differ significantly in how they’re installed, how they age, what they cost over time, and which problems typically show up years down the line. Budget might pus

In recent years, flat roof design has come under increased scrutiny, particularly around fire safety, durability, and long-term performance. Against that backdrop, BS 6229 was revised in 2025 , introducing clearer expectations around how flat roofs should be designed, specified, and delivered. A common question from Irish design teams is:  Why does a British Standard still matter in Ireland, especially post-Brexit?  And just as importantly: what has actually changed in the 20

Energy prices continue to rise, and most homeowners in Ireland are now looking for real, long-term ways to reduce heat loss rather than quick fixes. Your roof is critical in this equation. A poorly designed flat roof can leak heat all winter; a well-designed system can significantly cut energy consumption and improve comfort. At QBM, we do not supply tiles or metal sheets for pitched roofs. Instead, we specialise in flat roofing systems – bituminous membranes, PVC single-ply,

Flat roofs require reliable, long-lasting protection. Among the available options, EPDM roofing has become one of the most widely used solutions for domestic extensions, garages, garden rooms, modular pods, and off-site constructed buildings across Ireland. If you are planning a flat roof, whether for a home improvement project or a factory-built modular structure, understanding EPDM’s capabilities, benefits, and applications will help ensure you select the right membrane sys

Choosing the right roof for your home is not just about appearances. It is about protection, longevity, compliance with regulations, and overall value. For many Irish homeowners, the key decisions are now happening on flat and low-slope roofs – extensions, dormers, balconies, garages and terraces – rather than on traditional pitched roofs. At QBM, we specialise in flat roofing systems and accessories supplied to professional roofing contractors and design teams across Ireland
