can anybody tell me what is the official name for the system with the spinning things on top of your roof.
the one that are supposed to make your house less hot.
where to buy?
what's a good brand?
how much is the going rate for a normal intermediate double story house? (material + installation cost)

Turbine vents... those are the spinning type...

Or if you have the money you can install a fan driven ventilator...

edit:

As for brands I've come across mostly generic...

Here is a tip pick one with self lubricating bearings because after some time turbine might squeak and drive you nuts on windy nights...

The other thing is to make sure your place is fairly windy, if the air is mostly still then turbines don’t work at peak efficiency…

any idea on price?
need to budget.

Those ventilations create dust after installing . My house have those type too. It is now sealed completely because a few screws came off and the dust keep falling on to our furnitures.

Better look for other types of ventilations. Luckily I haven't seen any rats falling down from the hole as one of them is just right above my bed. Fuuh!!

Bunnyhoney, your room is directly below the roof tiles? There is no ceiling between the roof tiles and your room? Or is there any ducting?

Other types of ventilation I could think of are:-

1) Normal eletric wall mounted ventilation fan
2) Ventilation tiles

Any good suggestion on this? As I'm considering in place this to have free air flow in the house instread of eletric type.

Is DENKO brand good?

need some recommendation too, planning to get 2 on the roof since this new house pretty hot

how much it will take to do this?
sounds good.

several type exist..
1)residential/commercial/industrial
2) size-12"; 14" 16"

price for 14" residential about 160

it does really help?
Beside the dust and possible noise after sometimes... any other problems?

My place is quite windy, wonder how must the installation would cost.

TELL ME ABOUT YOUR ROOF DESIGN....

metaldec? tile? insulated? etc

160? Are you refer to the Ventilation fan like Kitchen / Toilet type or the Turbine vents type?

Bro Tiles.. red tiles...
