Repair or replace a roof in Antwerp

Repair or replace a roof in Antwerp

Repair the roof when the damage is local and the structure is still sound. Renovate when leaks, a worn covering or a failed underlay keep returning across much of the slope. A roof check on site makes that distinction. A photo does not.

The difference

A repair replaces or closes what is broken: a few tiles, a flashing, a penetration or a local joint. The rest of the roof stays.

A renovation replaces the covering across the slope, and often the battens or underlay if they can no longer do the job. That is different work, with a different price.

When a repair is enough

One leak after a storm, a broken tile or a loose valley usually points to a local fault. If the underlay is dry and the timber is still firm, repair comes first.

A roof under twenty years old rarely needs a full replacement just because one spot is wet.

When renovation makes more sense

If the leak returns in several places, tiles are dished or the underlay has failed, a new tile will not fix it. The same is true when rafters are soft from rot.

Age is not a rule. Past forty years, look first at the underlay, battens and drainage, not only at the colour of the tiles.

What this site's guide price says

For concrete tiles in ordinary wear, the calculator starts at €85 per m². The top of the range is 30% higher, because an estimate is not a quotation. For 100 m² that is €8,500 to €11,050.

Natural slates start at €145 per m², so €14,500 to €18,850 for the same 100 m². A poor roof, with rot or leaks, adds €30 per m².

Those amounts include 6% VAT only if that rate applies to the work, and they exclude grants. A final price follows an inspection of the structure.

What often matters in greater Antwerp

Terraced houses in Antwerp, Mortsel, Edegem or Kontich often have a pitched tile roof on the main house and a flat roof on the extension. Those need different work.

In Brasschaat, Schoten, Schilde and Kapellen, detached and semi-detached houses have longer gutters and more roof area. The calculator therefore runs from 30 to 350 m².

FAQ

Can a photo decide between repair and renovation?

No. A photo shows the covering, not the underlay or the timber. Nova Group starts with a roof check at the address.

Does a roof older than forty years always need replacing?

No. Age is a reason to look more carefully, not a reason to replace the roof at once.

Is the guide price fixed?

No. €85 per m² for concrete tiles is the start of the estimate on this site. The quotation comes after the inspection.
