Thanks so much

when buying hardwood for roofing, consider Akun, Itara, Ogborugboru, Koko Igbo, Ayin, they are good wood that stand the test of time

HSLBroker Sir,
1. I noticed in your quote you didn't add that thick wire used to hold the wall plate and passed through the blocks. Or is that an old school method?
2. If it's not the proper way, how then are wall plates fastened in the internal walls?
3. Have you used or heard of Chinese nails for roofing? Please educate us on the nails used for roofing.
Thanks

HsLBroker:
maybe I forgot Sir, that will not be a problem, you are referring to Oja agba, 3 Dozens will be ok, but if you have a parapet there won't be need for the usage because cutter rod is already inside the parapet.

The Chinese nails are good for roofing just like uk nails too, better than traditional nails

Thanks for the reply

Does the Oja Agba apply to internal walls even when quarter rods are used in the external parapet?

Please what is the cost of the Chinese or UK nails in bags? Do you also use them?

HsLBroker:

topmosttee:
I got it. Thanks a bunch.

I have responded. I am also awaiting your reply on the aluminium quote.

Thanks

HsLBroker:
you 're welcome sir, but the issue about quote for the aluminum roofing sheets without taking the physical measurement of the wooden carcass for aluminum roofing sheets is that you can't get accurate measurement now this is just an estimate and it will be plus or minus 10%, this is just for you to have an ideal of cost, physical measurement still be need to taking to get the accurate measurement. Thanks sir

topmosttee:
Yea, i am aware buf i would just love to have an idea if what to prepare for. Plus or minus 10% is fyn.

Thanks

From the picture above you can see the height of the roof of building and the length and breadth of building is already shown in the floor plan, so left to be known is the rafter or the fall ‘x’ as shown in diagram above.

Remember the Pythagoras theorem in secondary school days used in calculating the longest part of a right angle triangle.

The numbers of wood to be calculated also depends on spacing for the purpose of this exercise, we are using the format in diagram above as our specifications for our calculations.

For ceiling noggins of 600mm centers it simply means the wood are nailed 600mm apart, so add the breadth of plan and 600mm as overhangs both sides i.e 7,800mm or 7.8m +1200mm or 1-2m=9meters

Then divide by 0.6m=15pcs of 16.975m of 50 by 50.

For the longitudinal portion, 16.975+1.2m(the overhangs of 0.6m both sides)=18.175m then divide by 0.6=31 pcs of 9m of 2” by 2” ( Note how the length on one side is used to calculate the pieces/numbers of wood required for the length of the other side)

So to know the number of 2 by 2 to buy in the market for the ceiling noggins-

18.175m x 15pcs=273m of 2” by 2”

9m x 31pcs=279m of 2” by 2”

Total=552m

In the market, the wood comes in 3.6m per piece

So 552/3.6=153 pcs of 2” by 2” timber to buy in the market for ceiling noggins.

WALL PLATE is the timber/wood that are placed on top of blocks or roof beams as the case may apply, so for the fastest way to calculate this, is to add the entire walls length and divide by 3.6m to know the numbers of pieces you need. I am using approximately 100m.

So for 100m, divide by 3.6=28pcs of 3” by 4” or 75mm by 100mm to purchase in the market for timber named wall plate.

For FACIAL BOARD, remember the length and breadth of the plan of the building with its overhangs of 0.6m each, so add the perimeter

9m+9m+18.175m+18.175m=54m

Divide 54m by 3.6m=15pcs of 1” by 12”

For TIE BEAM, going by the section, it was recommended that we lay the timber named tie beam which is 2” by 6” or 100mm by 150mm at 1.2m centers apart. So what we need to do is to follow the same format used in calculating the ceiling noggins but it is going to span only the breadth of 7.8m only.

So divide 18.175m by 1.2m centers (spacing)

=15pcs of 7.8m =117m, then divide by 3.6m to know the numbers to buy/purchase in market.

117/3.6=32pcs of 2 by 6 of wood termed as tie beam to buy in the market.

STRUTS are a bit complex to calculate, they are the members placed diagonally as shown in diagram to connect the rafter with tie beams. We can use the numbers of tie beams and multiply by 2-

i.e 32 pcs multiply by 2=64 pcs of 3 by 4 or 75mm by 100mm termed as struts to be bought in the market.

For RAFTER, check the height of roof and the breadth of plan to determine the rafter which is the falling portion of the roof (except is already given from the section)

Lets take the height of the roof as 3.5m and the breadth of plan plus overhang is 9m.
