Woodworm in Roof Timbers – What Chorley Homeowners Need to Know

Why Roof Timbers Are Susceptible to Woodworm

In many Chorley homes — especially those built with older or untreated timbers — roof and loft structures can be prone to infestation by wood-boring beetles, commonly referred to as woodworm. The most frequent culprit is the Common Furniture Beetle (Anobium punctatum), which prefers softwoods and can weaken beams, rafters, and joists over time.

Key Signs of Woodworm in Roof Timbers

When checking your loft space, look for:

Tiny round exit holes (1–2mm in diameter) in timber surfaces
Fine powdery dust (frass) beneath beams or on insulation
Brittle or weakened timber when probed with a screwdriver
Tunnels in cross-sections of damaged wood
Dead beetles near loft hatches or window sills

While these signs can indicate past activity, only a professional inspection can confirm whether the infestation is active.

Why Infestations Occur in Loft Spaces

Woodworm thrives in timber with a moisture content above 18%. In roof voids, this is often caused by:

Poor ventilation, trapping humid air
Condensation forming on cold rafters and joists
Water ingress from minor roof leaks
Lack of preservative treatment in older timbers

Effective Treatment Options

At Weather Wise Solutions Limited, our treatments are tailored for lasting results:

Inspection & species identification – Confirming the beetle type and activity level
Moisture assessment – Ensuring environmental conditions won’t encourage re-infestation
Application of professional timber preservatives from PAM Ties
Replacement or reinforcement of severely damaged timbers
Ventilation improvements to reduce humidity levels in the loft

Why Choose Professional Treatment Over DIY

DIY surface sprays rarely penetrate deep enough to kill larvae within the wood. Our professional-grade products and application techniques ensure thorough coverage and effective eradication.
