Well I believe its an estimated quotation which can never give an acurate measurement. It will only guide you.
He didn't make provision for cladding, and flashings ( ridge, gutter, eave angle, bottom, e.t.c )

This are Zinc and Aluminium roofing sheets - but they're not as good as Longspan.

It's better to use Longspan or Asbestos roofing sheet (IN MY OPINION)

not that what I calculated for is LONG SPAN ROOFING - if its GERRADE it wld be more... also, I assumed the eave projection was 450mm.. if its wrong, what was used on site.

lastly, I only calculated the roof covering minus the others cladding etc...
Re: How To Practically Calculate The Quantity (m2) Of Roofing Sheet Required by osayuwamwen(m): 11:05am On Jan 15, 2025
Yes it for long span aluminum stucco

go with the 2nd or 3rd guy - both are about same.

Note: apart from the Length, Breath and King post you sent; there are other measurements needed to calculte Area of Roofing (which you did not send) and I assumed dimension for those/

So. my area of 340m2 might not be accurate.

Good day @Saydfact and others.

Thank you for the calculation presented.

Please can you help me with the calculation of this plan? Gerard is preferred, but I would appreciate it if you could add a quote for long span also.

I am curious also, is there a way to estimate wood also?

Thank you for your time

Evening...
On wood - the answer is yes. But it needs a lot of experience..

Your roofing is in the region of 420-450m2
I won't advice long span because of the many small entities.

Goodluck
