Greetings All -

I've been a silent member of Nairaland for quite sometime, but I'm now stepping forward to tap into the experience and knowledge of its members.

Please excuse me if I use incorrect construction terminology.

I would like to know if there is a functional difference between flat and raised roofs? Will the installation of a flat roof cost less than a raised roof over the same sqm of living space? I'm assuming it would cost less because less material will be used.

Thank you in advance.

Yes it will cost less, cause the height of roof determines the area qty. Where is the location of your project? May be we can help you in any way. We do stonecoated roof and aluminium longspan. 07038092452.

Thank you for your reply.

We've not yet settled on a location. The search continues, but my wife and I are already discussing the style of the home so I wanted to confirm the raised roofs only purpose is to cover the living spaces.

Are there any advantages in a raised roof over a flat roof?

Yes, a raised roof drops water freely and faster than a flat roof thereby leakage is avoided. And the beauty of the material profile used on the roof is more obvious, which add value and taste to the structure as a whole.

My dream of a roof-top deck is slowly slipping away.

I'd like to get a second opinion from the experienced builders on Nairaland (others are welcome to respond).

The image attached is not my house, nor is it my proposed house but I want a rooftop deck similar to what you see. The only difference is the rooftop deck I am hoping for will be above my dinning and guest room, not a garage.

Would a rooftop deck for entertainment require the same level of support that is required for decking that will be used to support first level living (bedrooms, masters suite, additional cement blocks)?

Can a thin slab be poured for the deck? Is there an alternative to achieve a roof top deck?

Thanks in advance for your responses.
