Bitumen roofs

Bitumen roofing started to gain popularity as a roofing material in the early 20th century. Its main component, bitumen, provides it with waterproofing properties, resistance to weather conditions, fire, mechanical loads, and dimensional stability.

Initially, bitumen roofing was primarily used on flat roofs or roofs with very low slopes. However, after World War II, the production of bitumen roof shingles, also known as bitumen shingles, began.

Bitumen roofing, or bitumen waterproofing with granules in strips, is a versatile roofing option that requires minimal maintenance. It is widely used in the construction industry for covering flat roofs of multi-story buildings, houses, industrial facilities, and more. The bitumen strips with granules are welded onto various substrates without the need for screws or nails, ensuring a completely watertight roof. Consequently, it is considered one of the most reliable options for flat roofs.

On pitched roofs, bitumen shingles are the most commonly used, although bitumen strips can also be utilized. The greatest advantage of bitumen shingles is their lightweight nature, starting from 3 kg/m2, making them suitable for various types of structures such as houses, canopies, garden sheds, or garages. Due to their low weight, they are particularly suitable for roof renovations. In some cases, they can even be installed over the existing roof covering. Additionally, bitumen shingles can be applied to roofs of different shapes and with various slopes, ranging from 3° to 90°, and they can effectively cover uneven surfaces.

Bitumen shingles are available in various shapes, from rectangular to multi-angular, and they come in different dimensions and colours that do not fade over time. The installation of bitumen roofing is exceptionally straightforward. Depending on the manufacturer and the quality of the bitumen shingles, warranties of up to 25 years are often offered for this type of roofing material.


Isola shingles are made on a fibreglass carrier. When laid on a wooden roof surface, they provide a safe and functional roof for several decades! The combination of the fibreglass mat and dense, flexible bitumen allows the product to be strong and highly flexible at the same time. Large self-adhesive surfaces with special strong adhesive ensure a durable and waterproof roof. Through pressure and heat, Isola bitumen shingles adhere firmly and successfully withstand storms and rain. The slate granule coating provides protection against UV radiation and mechanical loads.

Bitumen roofing has been present on the Slovenian market for a long time and has maintained a significant share among all roofing materials. The use of bitumen roofing is extremely suitable for complex roofs, as the basic sheet can be formed into the most demanding shapes and cover all slopes from the smallest (3°) to vertical (90°). That is why it is cost-effective for complex roofs compared to other roofing materials, as there is no need for additional elements, which are always very expensive and often represent a greater cost than the expense of all basic roofing elements.
