Improper Ventilation
Oftentimes, moisture or condensation you notice in your attic may not actually be from a leaking roof, but rather from improper ventilation in the attic or an attic that is not properly insulated with a vapour barrier. Proper attic ventilation is crucial to the optimal function and longevity of your roofing system. Venting from bathroom fans, washers, dryers and dishwashers, must be properly vented outside and not into your attic. If any of these elements is installed poorly or incorrectly, it can cause moisture buildup in your attic potentially leading to mould development and rotting wood.
