A composite roof is a modern roofing solution that combines the aesthetics of natural materials with the practicality of synthetic materials. Composite roof panels can replicate slate, tile, or wood shingle — yet they are lighter, more affordable, and easier to install than the original materials.

Why choose a composite roof?
A composite roof is an excellent choice when you want the appearance of natural materials without their drawbacks. For example, a slate-look composite panel weighs a quarter of genuine slate, so it does not require structural reinforcement. Composite materials withstand weather conditions well and are nearly maintenance-free.
Types of composite roofing
Composite roofing products fall into three main categories: slate replicas, tile replicas, and wood shingle replicas. The materials are typically manufactured from recycled plastic, rubber, fibres, and crushed stone. Leading manufacturers (DaVinci, BRAVA, EcoStar) offer an extensive colour range.
Composite roof pricing
The price of a composite roof is typically 50–80 €/m². It is significantly more affordable than slate (120–250 €/m²) or copper (100–180 €/m²), yet offers a similar appearance. Installation is faster and easier, which also reduces labour costs.

Composite roofing in Finland
The popularity of composite roofing is growing in Finland. They are well suited to the Finnish climate — the materials withstand frost, freeze-thaw cycles, and UV radiation. A composite roof is a particularly good option when you want the look of a tile or slate roof without the structural load.
Composite roof maintenance
A composite roof requires little maintenance. Removing moss and debris and cleaning gutters is usually sufficient. The material does not need painting or coating. Individual damaged panels can be replaced easily. We recommend a professional inspection every 10 years.
