Warm air gets out through the roof by a process called convection. Think of your entire house as a chimney. The heated air is spread out through your house and eventually goes up to the top of your home which boosts air pressure close to the ceiling. The primary difference between the lower pressure from the external environment on a colder season and the pressure inside the house, will force the warm air through any gap, crevice, and crack. Aside from that, the high pressure at the very top of your house develops low pressure close to the bottom of your home. Therefore, tugging colder air into your house through any cracks or openings surrounding your home’s foundation.
The first thing you have to do is conserve energy and begin saving cash right away, by stopping heat from getting out. Close up any gaps that lead from the living space and then to the attack. Monitor the areas around the wiring and the pipes. Inspect the ceiling and the attic floor and close up any cracks or holes. Check the door and window frames. Finally, have your roof inspected for any breaches or failing shingles. Even the tiniest of holes can lead to significant problems.
