Most homeowners know that they need to be watching for damaged shingles or water leaks when monitoring the condition of their roof. What many homeowners fail to realize is that ventilation also plays a critical role in the performance of a residential roof.

Your roof must be properly ventilated in order for your home to function efficiently as a whole. Paying attention to your roof's ventilation can yield some important benefits that you will want to take advantage of in the future.

1. Reduced Energy Costs

Roof ventilation plays an integral role in the performance of your home's HVAC system. Vents in your attic allow hot air to escape through your home's roof. As the hot air moves out, cool air takes its place. This keeps your attic at a lower temperature than the attic in a home without adequate ventilation would be.

A cooler attic means that temperatures within your living space will remain lower, allowing your air conditioner to expend less energy to maintain comfortable temperatures inside your home. Your HVAC system will last longer and you will have more affordable utility bills when your roof is properly ventilated.

2.  Even Heating and Cooling

A home that has extreme temperature fluctuations from one room to the next may not have proper roof ventilation. When there are not enough vents for hot air to escape the attic, or the existing vents in your roof become clogged, then pockets of heated air can become trapped within the attic space.

These pockets of heated air translate to pockets of warmer temperatures within your home. Clearing out clogged vents or having a local roofing company install additional vents in your roof can help you even out the heating and cooling that takes place within your home. Eliminating temperature fluctuations makes your home more comfortable over time.

3. Extended Roof Life

Replacing a residential roof can be costly. Most homeowners want to extend the life of their roof for as long as possible, and proper ventilation can be a valuable tool in accomplishing this goal.

Ventilation prevents a heated attic space from creating too much heat beneath your shingles in the summer. Excessive heat could damage the underside of your shingles, causing them to fail prematurely.

During the winter months, ventilation prevents your attic from retaining heat that can contribute to ice dams. Ice dams can cause extensive water damage to your roofing materials, requiring costly repairs or a total replacement. Rely on proper ventilation to help you extend the life of your roofing system.
