Ventilation 

Your home needs to breathe, which is where home ventilation comes in. Roof caps can enable hot attic air to be continuously exchanged for the cooler air outside, making it a lot simpler to keep the home temperature at a level that is comfortable.  Among other things, the caps can provide a practically invisible and attractive solution for the issue of an unbearably hot attic. Meanwhile, bathroom exhaust fans will rid the bathroom air of excess moisture, humidity, odors and other pollutants. It also helps to remove water vapor that has accumulated on mirrors and walls. Drywall is porous and paint is breathable, so the moisture can seep into the drywall and create fungal growth often in places you cannot see it.
