Apart from aesthetics, high roof has no special advantage. It is even a disadvantage in case of maintenance because carpenters will find it difficult to maintain good balance when carrying out repair works on the roof.

There is a popular saying amongst carpenters: a high roof is the gateway to heaven.It insulates you against them sub saharan heats.

gasparpisciotta:


Kindly watch out for any new roof installation around your area, you will understand better

Arcbox:

Can you come up with your points! Mumu

atiku4President:

Lies. The higher the roof the higher the angle of elevation which reduces the impact of rain on the roof and increases durability.
On high-slope rooftops, gravity makes any moisture from water to be quickly channelled t down into gutters. The lower the slope, the longer moisture lingers on the rooftop where it degrades materials and turns weak spots into leaks

I dont need to. or have you watched out for any new roof installation around your area?

If it's a disadvantage to maintenance, how was the roof installed?

This is pure lie!

Cross ventilation is achieved in a building with good opening not from the roof.

Lifemanage:

Wrong. By experience they all leak. Na format for more money by the carpenter. Nothing special

BloomingDale:
To prevent their neighbors from getting fresh air.

The carpemter makes less when the roofs are high like this.
The amount of wood being used are less too.

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.

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.
