Why Is Roof Ventilation Important?

Although you may be aware that the majority of roofs are ventilated, you may not be sure of the reason for this. As well as vents on the outside of the roof, ventilation within the attic is just as important and many homes do not have enough. This lack of ventilation can cause damage to the roof and home, as well as increasing your energy bills.

The ventilation in your attic is important for air flow, otherwise the air would just sit causing heat and moisture build up. When outside air flows in and out, it cools the space and prevents this build up, as well as creating an air balance which makes your home more comfortable and will maintain your roof condition.

When there is not enough ventilation in your attic or roof, it can cause the loft area to overheat, which heats up the rest of the home. During the summer, this can cause wasted energy to try and cool down the property. This heat can also reduce the lifespan of the shingles on the roof which can be expensive to replace.

The heat caused by a lack of ventilation will also cause a moisture build-up both inside and outside the property. On the outside of the roof, algae and moss can thrive in a moist, warm environment. Your roof will require a professional roof cleaning Surrey to remove this before it damages the roof. On the inside of the home, condensation and excess moisture can build up in the insulation, damaging it.
