Renovation of flat roofs – how to effectively restore the tightness and durability of the roofing?
Check out practical methods for renovating bituminous felt.
Flat roofs, compared to other types of roofs, require more frequent renovation. Reinforced concrete structures with a slight slope (from 2% to 15%) covered with bituminous felt usually need periodic refurbishment or local repairs. The use of modern bituminous materials for this purpose is one of the most practical and economical solutions.
Renovation methods – what to choose?
One of the most popular methods of renovating flat roofs is the use of renovation coatings. They work particularly well in critical areas – around chimneys, parapets and other details where leaks most often occur. Their great advantage is that they do not require advanced equipment or specialist knowledge, so the works can be done independently. This is a practical solution for those who want to renovate their roof quickly, effectively and without hiring a roofing team.
Renovation products – what to look for?
Before you start renovation works, be sure to check the substrate and repair any defects and unevenness. Minor defects can be quickly levelled with a sealing compound, such as NEXLER Arbolex Aqua Stop, which adheres perfectly even to damp surfaces. You do not always have to replace the entire covering – often it is enough to repair microcracks or apply a special protective coating.

A roof that leaks after two seasons? Complaints, lost customer trust – something every roofer wants to avoid. That is why proper substrate preparation, including priming, is not a detail, but the foundation of durable and trouble-free roofing. Although it may seem like a mere ‘formality’, in practice, priming has a huge impact on the durability, safety and effectiveness of the entire waterproofing system. In this article, we explain briefly and concisely why priming is not an option but a necessity.
