Furnace Roof Vent Replacement Cost Lagos

If your property in Lagos has ageing or faulty roof venting for your furnace or HVAC system, planning and understanding the replacement cost for a roof vent in Lagos is key. Efficient roof ventilation supports proper exhaust of furnace or HVAC emissions, maintains indoor air quality, and protects your property asset.

What a Roof Vent Replacement Entails

Replacing a roof vent (for a furnace or HVAC exhaust) typically includes:

• Removing the old vent and flashing or boot

• Inspecting roof structure around vent area for rot or damage

• Installing a new vent cap/flashing suited for the system (exhaust hood, turbine vent, ridge vent, etc)

• Sealing and weather‑proofing the connection (flashing, sealant, roofing membranes)

• Ensuring compliance with ventilation, safety and roof integrity standards

Estimated Cost Range

Based on typical repair and replacement projects in Nigeria and Lagos in particular:

• Minor roof vent replacement (simple roof access, minimal roof repair) — likely in the range of ₦80,000 – ₦200,000

• More complex replacements (higher roof, additional roof structure repair, premium vent materials) — could rise to ₦200,000 – ₦500,000+

• If major roof work is needed (e.g., replacing decking, flashings, or extensive damage) the total cost can escalate significantly upward.

Tips for Budgeting and Hiring Contractors

• Secure multiple quotes from reputable contractors and compare what’s included (parts, warranty, access, roof repair).

• Ensure the quote clearly lists the vent specification, labour cost, roof access requirements, and any roof repair scope.

• Check the contractor has roofing licence/credentials, good reviews, and bases the quote on inspection.

• Factor in contingency for unexpected roof structural issues—add ~10‑20% to budget to cover surprises.

• Consider scheduling during dry seasons when labour is less disrupted by rain and cost may be lower.

• Keep documentation of the replacement (photos before & after, warranty) — useful for property value and future maintenance.
