Cost Analysis: Timber vs. Steel Truss Roofing Systems
Weighing Durability Against Initial Cost
The roof structure is a long-term investment. Choosing between the traditional timber frame and the modern steel truss system involves comparing upfront costs, long-term durability, and maintenance requirements.
Timber Truss System
**Pros:** Lower initial material cost, readily available skilled local labor for installation, and easy to modify. **Cons:** Requires anti-termite treatment (pressure-treated timber is preferred), susceptible to warping and rotting over time, and high fire risk.
Steel Truss System
**Pros:** Superior strength-to-weight ratio, completely fireproof, impervious to pests (termites) and rot, offering a lifespan of decades with minimal maintenance. **Cons:** High initial material cost, specialized welding and installation skills required, and potential for corrosion if not galvanized and painted properly.
**Conclusion:** For low-budget, simple residential homes, timber remains viable if properly treated. For high-value commercial properties or large complex roofs, the **steel truss system** offers superior peace of mind and long-term cost savings on maintenance.
