Flat Roof
Residential flat roofs are a popular choice for modern homes due to their sleek design and efficient use of space. These roofs not only provide a contemporary aesthetic but also offer practical advantages, including additional usable space that can be transformed into rooftop gardens, patios, or solar panel installations. Flat roofs are generally more cost-effective to construct and maintain, though they require proper drainage systems to avoid water pooling. With advancements in roofing materials and insulation, flat roofs can be both durable and energy-efficient, making them a smart option for homeowners looking to optimize their living space.
Why Self-Adhere?
For over a century, multi-ply bituminous (asphaltic) roofing has been trusted for its unmatched durability, consistently protecting buildings and the valuable assets within. However, traditional installation methods often come with drawbacks—time-consuming processes, heightened safety risks, and unpleasant odors that can disrupt building occupants.
Self-adhered modified asphalt roofing offers all the proven benefits of this time-tested material without the usual challenges. Faster to install, easier to learn, and free of the downsides of traditional application methods, it’s a modern solution for contractors seeking efficiency and performance.
Flintlastic SA has been the leading self-adhered roofing solution for nearly 20 years, renowned for its superior bond strength and the comprehensive support we provide. Whether you’re working on a residential or commercial project, discover why Flintlastic SA is the go-to choice for contractors nationwide.
