Feasible in the far north with low rainfall, but a disaster in the southern and central parts of Nigeria that get Heavy rainfall and must use some type of Gable roofing.

Besides why would anyone want to roof a proper house with Flat roofing?
Na warehouse you dey build abi residential building?
If you want to build , make sure you invest your best into your personal space and build properly, pricing not withstanding.

I am in the bid to roof my house and I am constrained to weigh different options due to cost implication. the cost I got for my roof design including facial wall for the roof is about 2m. However, I started thinking about flat roof designs may be it will be cheaper and beautiful.

My questions,
1. What are the pros and cons of it in Nigeria?
2. Is it cheaper to do and what volume of savings?
3. Is it affected by rain or sun reflection on the building?
4. Do Nigerians use or not?
5. If they don't why?



cheers

Did i hear you say "why would anyone want to use flat roof"?
Am an architect, Flat roof is unique for me.

1. Is cheaper
2. It gives building a unique look
3. It controls the flow of zinc rain to one side, meaning u don't need to spend much on Water collectors.
4. It has low possibility of leakages because it has no complications.

For the leakage u pointed out, just use long span and avoid much space between the poleins so that the roof won't cave-in overtime.

Thanks

Perhaps he means single-sloped roofs.

Flat (horizontal) roofs will only work in the driest deserts. Not even in northern Nigeria.

The trusses in a single-sloped roof are simple triangles and the king post (upright part of the triangle) can be as low as 1m to1.5m. Very economical on wood.

The roofing sheets will not be cut since the roof plan is just a rectangle, so no waste of roofing materials.

You will need to shade windows from sunlight though.

Placing hoods above windows or having trees (eg those tall slim trees) in the compound can provide shade.

Thanks, pls show sample of single slope roof for me to see. Regards

malcom2x:
By flat roof do you mean roof top? I've always preferred rooftop cuz of the large space for lounging and laundry line. I like Cotonou architectural designs. Each house stands out unique from another. I don't know why we don't really see that in Nigeria.

Kingharzyz:


Thank you very much.. I've been reading people comment and I discover its either they lives in village or its something else because flat roof its in vogue in lekki right now, it makes structures more beautiful, I'm planning on using it at my site. In fact all new wema bank structures at the moment are flat roofs... Its cheaper and beautiful

Jeezuzpick:


Something like this:

arcahmad:
Flat roof is more economical than pitch roof. The amount of money spent on flat roof can be 20% compared to pitch roof. But the choice of roof covering sheet matters to prevent early rusting.

Jeezuzpick:


Hmmmmm..... Nice design. But heavy rainfall will be a huge challenge o. I would introduce a very slight slope and introduce high discharge pipes to remove water fast.

The slope is to ensure even a little water does not stay on.

Chukazu:



Even Ghana has better designs ...

In Nigeria however, it's as if all the Houses are designed by the same architect ...no uniqueness
