Metal Trusses vs Wood Trusses in Ghana: Which is Better for Your House?
Quick answer: Metal (galvanized steel) trusses are more durable and maintenance-free but cost 30–40% more. Wood trusses are excellent for standard residential builds and are more budget-friendly. The right choice depends on your budget, building type, and long-term plans.
What is a Roof Truss?
A roof truss is the structural framework that supports your roofing sheets. It is the skeleton of your roof. In Ghana, two primary truss types are used: wood trusses (timber) and metal trusses (galvanized steel).
Getting the truss right is the single most important decision in roofing. A strong truss means your roof survives Ghana's heaviest rainfalls and strongest winds.
Wood Trusses in Ghana
What is a Wood Truss?
A wood truss (also called a timber truss) is made from treated hardwood timber cut and assembled on-site or prefabricated. In Ghana, plantation timber (such as Odum and Wawa) is commonly used.
Kinkok Roofing uses chemically treated premium timber that resists termites, rot, and moisture — addressing the two biggest risks of wood trusses in Ghana's humid climate.

Frequently Asked Questions
Q: Can I mix wood and metal trusses in one build?
A: It is technically possible but not recommended. Mixing materials can create structural inconsistencies. We advise choosing one system throughout.
Q: Do metal trusses make my house hotter?
A: Steel conducts heat but does not generate it. With proper insulation board or a sarking layer, temperature differences are negligible. We always advise on appropriate insulation during installation.
Q: How long do wood trusses last in Ghana?
A: Properly treated wood trusses in Ghana typically last 20–35 years. Kinkok Roofing uses premium chemically treated timber with anti-termite and anti-rot protection to maximize lifespan.
