When considering a long-lasting roof, it doesn’t end with quality shingles and strong underlayment installed by professionals. They’re certainly critical, but don’t forget the ventilation factor that expels summer heat and moisture-laden winter air that cause premature roof failure. How to install roof ventilation is a main ingredient for looking after one’s roof and why?

1. Protects Roofing Materials

Adequate circulation of air through the intake and exhaust vents controls temperature and moisture up in the attic.  It reduces thermal stress by expelling hot air during the summer that can lead to shingles cracking and aging too quickly. This ventilation process also keeps warm air from the living area from condensing on the chilly roof sheathing during the winter, a process that causes wood rot and mold growth.

2. Prevents Moisture and Mold Damage

In order to empty humid air that rises from the interior of the house to the attic, there must be constant airflow through the roof space. This is essential for inhibiting moist from forming on the wooden frame and underside of the roof deck that result in mold and mildew. Ventilation also guards against wood rot and guarantees that the roof assembly stays dry and lasts long.

3. Decreases Heat Buildup and Energy Strain

The concern over how much ventilation does a roof need is a vital line of defense against excessive heat that accumulates if disregarded. A poorly ventilated attic that’s extremely warn during summer can cause the roof decking to get overheated and the shingles on top to bake and crack. Effective ventilation in the upper part of the house also eases the burden on the home’s cooling system and reduces the bill for power consumption.

4. Reduces Ice Dams and Winter Roof Stress

Adequate ventilation is an essential line of defense against winter’s assault on the roof as well. It maintains a consistently cool roof temperature. Without it, the bottom layer of snow melts due to heat from the attic. Upon reaching the colder edges, this water then refreezes and creates ice dams that hold back more melted water. This pooled liquid can seep through the shingles and cause leaks or cause the deck below to decay.

5. Preserves Roof Structure and Insulation

The attic is kept consistently dry, and it keeps moisture from doing a number on the hardwood foundation of the roof that should serve as a secure platform for roofing materials. With the constant airflow, moisture is kept at bay in winter, and the temperature in the attic is cooler in summer. Both conditions contribute to the effective insulation that keeps a home comfortable and gives the roof a lot longer lifespan.

The Ventilation Victory

Proper ventilation is pretty much about keeping the temperature in an attic closer to that of the outside air. An equal amount of intake and exhaust is essential. This is why a professional installation must be done to fit the roof size and attic space of one’s house.
