in UK a LOFT is BUILT in it
most European people creates ATTIC in the ROOF due to space to build STORE or dump GARAGE as buildings are carved on No/little space

I Googled it and it's cool concept. I'll try to do that in my future house InshaAllah. Wooden floor instead of conventional concrete decking but the load there won't be much. We can be praying and eating there while beds, fridge, wardrobe and other heavy household items remain down. Thanks for the insight

Best fit answer!!!!!!!!!!!

its just a trend "send doen drain"

not so appropriate for nigerian climate

Thanks for bringing this to public discuss.

I have always had my reservations for this trend which is fast gaining popularity.

Firstly, the assertion of improvement in water run off does not hold water. A 45 degree slope is enough evacuate any amount of precipitation.

The idea may have started from people copying western designs without configuring them to our climate.
The high roof creates space for the attic which "oyibo" people also use as living spaces. But in our clime, you would fry to death because of the heat up there.

Some have adduced that it makes the house cooler. This is another misconception because simple physics should tell them that the larger surface area of roofing tiles or aluminium exposed to the sun increases the convection of heat into the living spaces.

More worrisome is the addition of cornices or parapet which prevents the roof from breathing thereby trapping tremendous heat in the attic and by extension the living spaces below.

Visiting old institutions built during the colonial era, you will marvel at how passive those design were and are liveable even without artificial cooling e.g UI main library, UCH main structures, ABH.

In a nut shell, increasing floor to ceiling height with clerestory Windows is more tropical oriented than the miss-fit we are discussing.

To prevent their neighbors from getting fresh air.

🤣🤣🤣🤣🤣🤣🤣

CoolAmbience:
Lol...
You must be really ignorant.
Any sane person knows that the higher a roof is away from its occupants, the greater the comfort they derive. We are talking impact of proximity as it relates to heat radiation here.

Funny how you people quick to insult when empty.

What is the standard recommendation for roof Design as par BS8110 or EC2?

I did a course on the revolutionary Cool Ambient Technology in far away North America, exactly ten years ago.

Simple analogy, do you feel the heat of fire more when it is closer or farther from you?
Try dey reason na, and be open to learning.

I repeat in building cross ventilation is achieved through openings not roof.

Advantage of high roofing


There's less danger of pooling water: On high-slope rooftops, gravity makes short work of any moisture—as the roof quickly channels the water down into gutters. The lower the slope, the longer moisture lingers on the rooftop where it degrades materials and turns weak spots into leaks.

relax. The major reason na because e fine

Didn't read all the comments .... and I'm not into architecture. I believe the high roof has nothing to do with rain .... but about making a larger roof area to install solar panels. These are sensible forward thinking people and not the follow follow type who in hot hot Nigeria be copying Europe cold climate house designs. Then they be broiling in their homes if they don't have commercial fans or can afford to run a/c 24/7. High roof also makes the house cooler. Hot air rises and will be wayy up leaving the cooler air at the bottom where people will be comfortable. The house becomes even cooler if a few windows are way up to allow the hot air to escape and cooler air sacked in through the lower windows. Such a house never needs a fan. We need to be building houses to suit our climate .... houses to allow heat to escape ... not to trap heat. We can see tht clearly in the US. houses in New York are not the same as those in Texas or Florida... NY houses are designed to trap heat .... Florida/Texas houses are designed to release heat. Even if they do .... they can afford to run a/c 24/7 .... can we?

Snacks... feel free .

Sorry, does that mean a set of windows up the wall and another set below?... Don't really understand

High roof top is actually an artistic purpose more, but there are some benefits too.
1. If properly design with all features in place, it helps in cooling the lower living space. A high roof with proper vent will definitely cool the room, because there is enough space to contain the hot air in the space., but if improper vent is not put in place it actually heat up the living space below. Most country with low extreme temp, usually use this design to hold up the heat during the day, some even create a living space within the roof space just to get some warmth.
2. Water run off on such high roof is good , because it prevent water sipping through weak point or dent in the roof. That is why flat roof are really prone to leakage easily so the more the roof slope the better it run off water due to free fall under gravity .
3. It has more stability than any other form of roofing, yes that very true. The higher the roof top the more is difficult for such roof to be blown off by wind or hurricane if well designed. This is because the air from above the surface during wind turbulence will be more and it will counter the air flow below the roof round the building .This type of roof design is actually meant for low high buildings course the roof serve as wind breaker, reason why it also helps in cooling. Because all wind directed at it,hit on the surface of the roof. So the more the surface the more the wind, so if the vent are in place more airflow will cool the surface of the living space. ( Note some design even direct the vent air flow back into the living space below the ceiling for heating and cooling the room instead of using burning fuel to heat the room, the heat gather in the roof during the day is allow to flow through the vent into the room .) But such design are only meant for country with extreme low temp..
So high top roof actually have important apart from it artistic view or beautification.

The disadvantages may include,
1. Required more materials to use up for a limited budget individual, the number of materials both the wood lengths and the roofing sheet is more compare to just moderate or flat roof
2. Excessive dead weight on the building, yes the number of truss that will linked up to complete the structure will add more weight the block work below

Hope this pic clears it up! I'm almost sure you saw several houses with similar roof designs ... but minus those upper windows. In this one ... there may be an attic ... if not ... when the small upper windows are opened ... the hot trapped up there escapes.

Are you jealous?

We heard in your own village una no even get roof . . . The few that you managed to have is all rusted brown

Guy your brain is just for nap time.
Sorry for your confusion

And I repeat, you are ignorant of what you are saying.

That's no insult. It is a statement of fact.

Is it angels that made the design recommendation that you talked about?

You can't talk about cooling in a building without paying cognizance to the amount of heat that radiates into the building from the roof...

Are you aware that over 70% of heat that comes into the building is from roof?
