Flat roofs

Flat roofs today are no longer just cost-effective alternative solutions, but they are part of future-oriented architecture that enhances the functionality of buildings.

Due to the increasing impacts of climate change, flat roofs must meet ever-increasing requirements, which is why high-quality selected materials for sealing with a long lifespan and their correct installation are crucial. Therefore, the roofing for flat roofs must be well selected, designed, and installed. The chosen roof membrane must be suitable, with proper waterproofing and thermal insulation.

A flat roof refers to a multi-layer roof with a slope of up to 5°, which is the most exposed part of buildings due to numerous construction and physical influences.
Depending on the utility of the roof surface, they can be classified as unused roof surfaces, which are walkable only for general maintenance, and used roof surfaces intended for human activity or traffic, including green roofs.

Flat roofs are particularly common in the construction of industrial buildings, but they are increasingly being seen in individual construction as well, as they offer unique solutions.

Our program includes the sale of high-quality membranes from recognized manufacturers. We provide a complete range of materials, accessories, and equipment for the quality implementation of flat roof systems.

Flat roofs can be categorized as cold roofs, warm roofs, inverted or semi-inverted roofs, and green roofs.

Unventilated (warm) roofs consist of a supporting structure, a sloping and levelling layer for the substrate, a vapour pressure equalization layer, a vapour barrier, thermal insulation, a waterproofing layer with an equalization layer, and a protective layer for the surface of the waterproofing.


Ventilated (cold) roofs consist of a supporting structure, thermal insulation, an air gap (ventilated), and an upper supporting structure with waterproofing.


Inverted or semi-inverted roofs have a layer of thermal insulation above the waterproofing. This protects the waterproofing from temperature fluctuations and the impact of UV rays (increased durability). The inverted roof system is highly suitable for renovating deteriorated flat roofs, as it improves thermal insulation and allows for new waterproofing.


Green or vegetated roofs have additions above the waterproofing that protect against root penetration, followed by a drainage layer, a filtering layer, and a growing substrate. Green roofs are also known as ecological roofs, as they provide valuable additional green space in urban areas.

We have a permanent stock of top-quality products for flat roofs from renowned manufacturers.

PVC roofing membranes
(SIKA, BAUDER, etc.)

PVC roofing membranes are multi-layered, synthetic membranes reinforced with polyester, based on polyvinyl chloride (PVC).

UV resistance of the membrane, resistance to point loads such as hail, various attachment methods (mechanical, welding).

FPO/TPO roofing membranes
(SIKA, BAUDER, etc.)

FPO roofing membranes are multi-layered synthetic membranes based on flexible polyolefin, known as TPO roofing membranes in the American market. To ensure longevity and dimensional stability, they are reinforced with a polyester mesh and a layer of fibreglass. The membranes are suitable for direct exposure to weather conditions and can be used in all climate conditions. They can be used for mechanically attached and ballasted roofs.

UV resistance of the membrane, resistance to point loads such as hail, various attachment methods (mechanical, welding), dimensional stability.

Liquid membranes

Liquid membranes are a versatile, ideal solution for flat roofs with numerous joints and various penetrations (ventilation shafts, air conditioning installations, etc.) and complex details. They can be used for both new constructions and the refurbishment of existing roofs. Due to their versatility, they can be applied over existing roofs without the need to remove the original roofing material. They can also be used as a material for waterproofing balcony pavements.

Bitumen tapes

Bitumen tapes are still the most commonly used solution for waterproofing flat roofs. In a traditional flat roof, they are installed above the thermal insulation, while in an inverted flat roof, the waterproofing layer is placed beneath the thermal insulation. You can choose between the conventional approach using standard bitumen tapes or opt for high-quality tapes.
