Building better roofs: Essentials for flat roof construction

Building better roofs: Essentials for flat roof construction
Flat roof construction requires meticulous planning, smart material choices, and strict compliance with industry standards. As a roofing contractor, you know that a successful flat roof installation extends beyond protecting the building to enhancing energy efficiency, safety, and sustainability.

Whether you’re tackling residential, commercial, or industrial projects, optimising every detail of the flat roof construction is critical for long-term performance and client satisfaction. In this blog, we’ll break down the essential components of a durable and reliable flat roof system, equipping you with practical insights to make informed decisions and deliver exceptional results on every project.

Materials that last
The foundation of a successful flat roof system lies in the materials you choose. The right materials not only affect the roof’s longevity but also its ability to withstand diverse weather conditions, UV radiation and general wear and tear. IKO offers a comprehensive range of flat roofing membranes to meet the needs of a variety of project types.

• Bituminous systems: Combining quality underlays, high-performance insulation and durable capsheets, IKO’s reinforced bituminous membranes ensure long-lasting performance. One such system is IKO Carrara, a durable, sustainable roofing solution. The mineral finishing of IKO Carrara systems is coated with a special type of titanium dioxide (TiO2). Under the influence of UV rays, the membrane acts as a catalyst and converts nitrogen oxides and sulphur oxides (NOx and SOx), which are contributory factors in the acidification of the environment and the greenhouse effect. Each of these gases are converted into harmless and environmentally neutral substances.
• Single ply membranes: IKO’s single ply systems, such as IKO Spectraplan TPE, are lightweight and easy-to-install solutions for large flat roof constructions, ideal for projects like warehouses, factories, and residential buildings. Free from hot works or gas torches, they have the potential to reduce insurance costs and simplify installation. Offering design flexibility, bespoke colours, and PVC standing seams for a metal-look finish, they suit a variety of projects across several sectors, including education and healthcare.
• Mastic asphalt systems: IKO mastic asphalt roofing systems are a trusted choice for both modern and heritage buildings, offering a seamless and durable waterproof finish. Mastic asphalt is often the original material used in historical structures, making it ideal for sympathetic restorations. Its proven longevity, resilience, and compatibility with a variety of substrates ensure it preserves the integrity of older buildings while delivering modern performance.

These are just some of the numerous solutions IKO produces to provide robust protection and ensure roofs remains functional for years to come.

Effective insulation for energy efficiency
Roofing insulation plays a crucial role in maintaining thermal comfort and ensuring the energy efficiency of a building. Insulation is often the unsung hero of roofing, as it helps regulate internal temperatures, reduce energy consumption, and comply with building regulations.

IKO’s range of high-performance insulation solutions is designed to provide exceptional thermal conductivity while reducing heating and cooling costs. IKO enertherm PIR boards are lightweight, slim, and easy to install, which makes them ideal for flat roof insulation. Incorporating high-quality insulation into a roof installation can ensure energy savings while adhering to the latest industry standards.

Reliable waterproofing for long-lasting protection
Waterproofing is the most critical aspect of flat roof construction. A failure in waterproofing can lead to costly repairs and structural damage, making it essential to select a roofing system that offers long-lasting, seamless barriers against water infiltration.

IKO’s waterproofing solutions are engineered to withstand diverse weather conditions. Whether you’re using bituminous, single ply, mastic asphalt membranes or other built-up systems, IKO’s systems help to ensure your flat roof remains leak-free and protects the underlying structure.

Safety and compliance: Responsible roofing
Safety and compliance are cornerstones of responsible construction, going beyond legal obligations to prioritise the integrity of structures and the wellbeing of occupants. Flat roof construction requires adherence to rigorous standards, the use of high-quality materials and a forward-thinking approach to sustainability and safety. With IKO, you can achieve all of this with confidence.
