Having a concrete slabbed roof is dicey but not impossible. It has to be taken care of greatly.
Bituminous felt or rubber felt should be applied. Very important.

Overall, is it cheaper or "much" more expensive than a pitched roof?

mufutau55:


I will say much more expensive o. We are talking about decking and other treatments.

That last part is what they use mostly in this part of the world for many roof including the concrete roof as a water sealant.

KolaShangOne:

Hajji..

The cost should be comparative. A little bit more or less or equal.

My decking cost was not any close when I did mine o.
But then you may be right.

we just competed a roof with Tilcor stone coated tiles. Woodwork and Tiles cost about 4.6million naira..

A deck of the house will cost less than that..

Hahaha. I can afford it if it's not very expensive and won't give me problems in the future.

Hello pro builders in the house. I will be starting my building project soon and I have been thinking about roof designs. Personally, I like the feel of flat roofs. But I had lived in a house that leaked heavily (just decking, no roofs). And this has given me reason to rethink.

The typical roof designs in Nigeria are pitched. Is this because of our weather? Is it more expensive or cheaper in the long run?

The idea for a flat roof is because I intend having a vegetable garden on the roof and of course DIY solar assemblies. Will this decision cost me more in the long run? And yes, I have limited funds

Hello guys,

I love this discussion.

I stand for flat roofs over pitch any day any time. But i prefer to use a different technique to dodge concrete slabs in a flat roof as much as possible.

What I do is I make the roof parapet high enough that it can accommodate the slope of a flat aluminium roof in a way it Is still not visible from the outside. It depends on the design of the house and hence the roof design. So in most cases it comprises of;

A flat sloping roof to one or 2 directions covered with long span aluminium roofing sheet

Gutters that drains the runoff water from in-between the alu minium roof and the concrete parapet

Gutters should be treated with water sealants

Drain pipes to channel runoff water from the roof to the waste water system.

I guess with this it's a problem solved. No need to bother about the disadvantages of decking.

I hope this helps.

Regards,

Arc. Efe

WE did something like that here on this project.

In fact you can collect water and pass it through drains in the pipes embedded in the columns as we did here.

After the deck, we applied felt (bitumen) on the parapet wall and controlled flow into the drain pipes..

but you won't be able to lounge on the roof with the aluminium roof. can you please put a picture

There's a technique I know of that solves this decking leakage. It involves the use of propane gas with a burner like what you see in fire extinguishers and neoprene sheets of say 4mm thickness. The idea is to heat these sheets and have them stick to the roof permanently. Most Control Buildings with decked roofs are done this way.

I may not be exact with the material name but I sure will pull up some records.

mikolo80:
I know there's always a way. I'm just trying to visualise your roofing sheet parapet set up.
