  1. Having a regular check on your attic ventilation should be fundamental as any delay could cost you a lot of money and time. You can do it yourself by making a checklist. It could have a lot of things to look but the priority should be to look if it is moist. Humidifiers or indoor pools could be the indoor sources for it. Secondly, check for intake ventilation. There should be at least 50% ventilation provided through intake vents. However, too much intake will pressurize the attic so the ratio should not exceed more than 60% intake/40%. It’s perfect for your attic.
