Professional Flat Roofing Designed For Norwegian Weather Conditions
Flat roofs are a practical solution for many Oslo properties, including extensions, garages, commercial buildings and modern homes. However, long-term performance depends on correct drainage, quality materials and professional installation.
Oslo’s climate brings challenges such as snow, heavy rain, freezing temperatures and freeze-thaw cycles. A well-designed flat roof helps prevent leaks, water pooling and premature damage.
We install durable flat roofing systems across Oslo and surrounding areas, including Grünerløkka, Sagene, Majorstuen, Frogner, Nordstrand, Ullern, Bjerke, Stovner, Kolbotn and Lørenskog.

Understanding Flat Roofing
Flat roofing systems are installed with a low pitch rather than the steep slopes found on traditional roofs. They are designed with a slight fall to allow rainwater and snowmelt to drain effectively.
A reliable flat roof depends on:
When these elements are correctly designed and installed, modern flat roofs can provide reliable performance for many years. Problems usually occur when drainage is inadequate, materials are unsuitable or installation details are overlooked.

Why Flat Roofing Is Popular In Oslo
Flat roofing is widely used for both residential and commercial properties because it provides flexibility in design and practical benefits. Common applications include:
Home Extensions
Flat roofs are often used on extensions because they provide a clean appearance while maximising available space.
Garages And Outbuildings
Flat roofing provides a practical solution for garages, workshops and additional structures.
Loft Conversions
Flat roofing systems are commonly used on dormer sections where a low-profile design is required while providing reliable protection against changing weather conditions.
Commercial Buildings
Large commercial properties often use flat roofing because it allows efficient coverage of wide areas while supporting practical building designs.
Our flat roofing Process
We follow a structured process to ensure every flat roof is properly assessed, installed and finished for reliable long-term performance.
Inspection & Diagnosis
We assess the roof condition, drainage, waterproofing and existing issues to identify the correct solution.
Roofing Installation
We recommend the right solution and install with attention to waterproofing, seams, edges and drainage.
Final Inspection
We check the completed roof to ensure proper drainage, secure waterproofing and quality workmanship.
Flat Roofing Systems We Install
We install a range of flat roofing systems selected for durability, weather protection and suitability for different property types.
EPDM Flat Roofing
EPDM is a durable rubber membrane system suitable for many residential and commercial flat roofs. It provides waterproof protection, weather resistance and relatively low maintenance when correctly installed.
GRP Fibreglass
GRP fibreglass creates a strong, seamless waterproof surface suited to roofs with complex shapes, multiple edges, roof lights and detailed junctions. It offers excellent durability, impact resistance and a low-maintenance finish.
Felt Flat Roofing
Felt roofing remains a practical solution for smaller extensions, garages and less exposed structures. The right choice depends on the roof design, expected performance and specific property requirements.
