What Insufficient Ventilation Does to Your Roof


May 15, 2020


Fewer components of a home are more vital to its comfort and safety than its roof. Various issues can contribute to this pertinent structure’s deterioration over time. One such matter is inadequate ventilation.

What Poor Ventilation Means For Your Roof

The Formation Of Ice Dams

On poorly ventilated roofs, warm air often becomes trapped. During the winter season, such events can precipitate the refreezing of melted snow that typically collects around the roof’s edges. Over time, frozen ice damn form because water cannot properly flow off the structure. Trapped water leads to increased moisture on the roof, which can lead to shingle damage and, ultimately, leakages that could seep into the home. 

Damaged Underlayment

The underlayment is placed directly atop a roof’s deck and cushions other roofing materials, such as shingles. Underlayment serves as an added protective barrier from harsh weather conditions like precipitation, wind and temperature extremes. Improperly ventilated roofs allow excessive heat to accumulate. As time progresses, this occurrence can damage this structure and eventually cause leaks.

Sagging

Inappropriately ventilated roofs often contain excessive moisture contents. Over time, water weakens the adhesive substances holding the roof’s materials together. This often precipitates a sagging and warped appearance. Moreover, such circumstances could pose a severe collapse risk for anyone traversing the structure.
