How Should a Flat Roof be Constructed?
To ensure durability and functionality throughout its lifetime your flat roof needs to be constructed with proper building techniques. With Avant Garde Roofing providing 15 years of expertise, we deliver top grade flat roof installations throughout the UK. Our detailed information explains how you can build a flat roof for maximum effectiveness.
Choose the right materials
Your flat roof will stand up better to weather conditions throughout its lifespan depending on your chosen materials. commercial flat roofs should be built utilising materials including EPDM rubber or TPO and PVC membranes. When installed properly synthetic rubber membranes provide seamless protection against weather while showcasing strong durability. For smaller domestic flat roofs personnel find bitumen felt to be cost-effective. Make sure to pick roofing materials that feature a least a 20-year manufacturer warranty.
Get the right falls
It's essential to build the right falls into your flat roof to allow water to drain effectively. We recommend a minimum fall of 1:40 - this means for every 40 units horizontally; the roof needs to drop 1 unit vertically. Any less and you risk water pooling on the roof. We'll assess your plans and advise on the optimal falls during the design process.
Pay attention to detailing
Effective water drainage requires building correct falls into a flat roof. We recommend a minimum fall of 1 for every horizontal distance of 40 units the roof covers it should descend by 1 vertical unit. Roof material won't perform optimally if the structural slope drops less than one unit for every 40 units horizontally. Our team will review your designs to recommend the best roofing falls throughout the developmental phase.
Hire professional installers
Even with the right materials and design, poor installation workmanship can still result in problems down the line. We have an experienced in-house fitting team who will install your flat roof to exacting standards. Or if using your own contractors, check references and ensure they have proven expertise fitting the type of flat roof you need.
Plan regular maintenance
Once installed, it's important to schedule routine inspection and maintenance to maximise your flat roof's longevity. We recommend checks at least twice a year, and after any major storms. Look out for damage, debris buildup and vegetation growth. Nip any problems in the bud before they escalate into costly repairs. With proper care, a good quality flat roof should last over 20 years.
