Sir, I can't tell for other materials.
But these the price of woods/nail,
2x3 wood N300 each
2x4 wood N350 each
2x6 wood N450/N500 each
3" Nail N7,500
4" Nail N7,500
5" Nail N8,000
I am the person managing our church building project, am the one that have been going to market materials.

Thanks a lot.

QS in the building.
Specifications are not complete and calculations incorrect
e.g
5) 5 inches nail 3 bags @ N8,500
Is it N8,500 per bag or per specific number or per half bag? etc.
if per bag then the calculation is wrong

for a 4-bedroom flat. Total cost of roof structure for N689,100 is still fair but can be reduced by 50k-100k depending your location

Yes, N8,500 per bag. Total = N25,500 not N255,000 that was a typo, can't edit it.

Location = A lagos sub-urb.

Thanks everyone for your contribution.

Here is the final quotation we got from a builder to lay the roofing wood for a 4 bedroom
house under construction on about a plot of land.
I'm not an expert in this area, let the experts in th house help me out. Is it ok?

1) Facial board 22 pieces @ N1800 each = N39,600
2) 2 X 6 wood 40 pieces @ N1,000 = N40,000
3) 2 X 4 450 pieces @ N500 = N225,000
4) 2 X 3 350 pieces @ 450 = N157,500
5) 5 inches nail 3 bags @ N8,500 = N255,000
6) 4 inches nail 2 bags = N17,000
7) Oja-Agba(3 bundles) @ 1,500 = N4,500
8 ) Labour for carpentry = N160,000
9) Transport = 20,000

Total Cost = N689,100

What I'm more concerned about are the prices of the materials and the specified
quantities.

I have removed the cost of omo onile.
