common upgrade alternatives for the attic, especially in the gable or peak spots. However, this practice is neither required nor recommended. Airflow is increased by an electric exhaust fan such that there can be too much for the soffit vents to process. This, in turn, will cause more air to be drawn from other parts of the home, causing the opposite effect to the one intended.

It is advisable to check on the condition of the attic a few times a year, especially after heavy rain or when it is cold. Be alert for wet areas, the presence of mold, signs of rot or even tiny "drip holes" that appear on the insulated areas or floor. Since attics can be of many different designs and come in various shapes and sizes, it can be difficult to assess current conditions. If accessing existing insulation proves difficult, you may need to seek professional assistance.
