Good ventilation is the key to a healthy roof system. A well-ventilated roof can last double the amount of time as a similar roof with no or poor ventilation. But why is that?
Ventilation allows for warm air to escape from under the roof, and allows for the cooler air from the underside of the roof to replace it. The ventilation system consists of roof vents/ridge vents, located on the top of the roof which allow for the hot air to escape, and soffit vents which are located on the underside of your roof’s overhang and allow for cool air to flow to the surface of the roof. This ventilation system ensures that heat does not accumulate on the roof surface, costing money and resulting in damage.
Lack of proper ventilation results in:
- Broken or damaged shingles from the extreme heat in the summer. Shingles can actually scorch and glue can melt off.
- Ice dams and large icicles: With a warmer surface temperature, the roof causes snow to melt. The melted snow then refreezes when it reaches a colder section of the roof, creating ice. This causes a dangerous condition outside, and can result in leaking inside your house.
- Moisture under the roof deck causing dry rot, mold, rust, and fungus
- High cooling bills in the summer. Heat from the roof has no place to go and will accumulate in the attic.
- Damage to your attic. The accumulated heat in the attic can result in moisture and mold
