This is an estimate based on average 2026 prices. Actual costs may vary. Always request multiple quotes for an exact price.

Cost factors

The total cost usually consists of:

  • Materials: 45-55% of the total
  • Labor: 30-40% of the total
  • Structure and finishing: 5-10% of the total
  • Permits and preparation: 5-10% of the total

These percentages can vary depending on the situation and materials chosen.

Why do prices vary?

  • Roof type and structure: The existing roof structure determines installation and reinforcement.
  • Size: Larger dormers require more materials and labor time.
  • Finishing: Windows, roofing, and insulation choices affect the price.
  • Permits and access: Permits and limited access can add extra cost.

Subsidies & incentives

In Belgium, this type of work usually does not qualify for a fixed regional grant like insulation or heat pumps do. The biggest financial impact usually comes from VAT, renovation loans, and local exceptions.

What usually helps

  • For homes older than 10 years, work carried out by a contractor often qualifies for 6% VAT instead of 21%.
  • Mijn VerbouwLening in Flanders and ECORENO in Brussels can help spread a larger renovation budget.
  • Municipalities may offer extra support for accessibility, de-paving, or neighbourhood renewal, but this is never automatic.

Always check

  • Whether a notification or permit is required.
  • Whether the work forms part of a broader renovation that does qualify under a regional scheme.
