Roof timber treatment: the guide before requesting a quote

How do you know if your roof frame needs treating?

Curative roof timber treatment becomes essential as soon as wood-boring insects have settled in. The telltale signs:

  • Holes in the beams: oval, 6 to 10 mm, the signature of the house longhorn beetle
  • Sawdust or frass in the attic, at the foot of timber pieces
  • Gnawing sounds in the roof frame, especially at night: larvae are tunnelling right now
  • Worm-eaten wood that crumbles or sounds hollow when probed

Preventive treatment of roof timber is recommended for old frames that have never been treated, before an attic conversion or when buying a property.

Worm-eaten roof beam attacked by wood-boring insects: galleries and crumbling wood
Infested beam: galleries, frass, crumbling wood. At this stage, a treatment by injection is still possible.

Is an infested roof frame dangerous?

It is the most expensive risk in the house. Longhorn beetle larvae tunnel through structural timbers for 3 to 10 years, invisible beneath the surface. A heavily infested roof frame or beams lose their load-bearing capacity: sagging roof, floors that give way, and in extreme cases complete replacement of the roof frame. Treating in time costs around ten times less than rebuilding a roof frame.

Roof timber treatment: what price?

It is the question everyone asks, so let us answer it: a roof timber treatment by injection starts from €1,500, depending on the volume of timber, the accessibility of the attic and the extent of the damage. A localised wooden beam treatment by injection costs less. The technical visit leads to a free, precise, no-obligation quote: clear pricing, no surprises.
