Roofing ventilation is something that most homeowners probably don’t think too much about—or know much about, period. In fact, unless you have worked as a Bedford roofing contractor in the past, you might not even be aware of how roofing ventilation works and why it’s so critical. Yet it plays a very important role in maintaining the life and health of your roof, so it’s important that you understand what it is and check to make sure it’s properly working each year.
Extending Roof Life
A roof is a major investment, and something that should last for several years (even decades), but it requires proper maintenance to ensure it will last. In a climate like Bedford this ventilation can maintain a more constant temperature in your attic, preventing excessive cold from causing issues like ice dams, and preventing heat and humidity in the summer from building up inside the attic that puts a strain on your cooling system.
Preventing Ice Dams
Perhaps one of the most important reasons you should check roofing ventilation in Bedford is to prevent ice dams from forming. In the winter when you heat your home, the warm air rises through your attic. Without good ventilation, this heat will continue to rise up to the roof, melting snow at the ridge. Unfortunately when it gets to the colder outer edges of your Bedford roofing, the melted snow freezes again and creates a “dam” that prevents water from draining into your gutters. This often leads to damaged shingles, leaks, and other problems.
Roofing ventilation also plays an important role in the summer when the weather gets warm. Without good ventilation hot air rises into the attic and remains—where it mixes with humidity in the air and can foster mold and mildew growth, causing rusted nails, fasteners, and screws. These issues often lead to Bedford roofing damage, but can be prevented if you have a way for air to move freely from the attic to the outdoors. Moisture control also helps reduce the strain on cooling systems, which won’t need to work as hard to keep the house cool if the temperature is more constant throughout.
Proper ventilation for your Bedford roofing is important to preserve the life of your roof, prevent ice dams, and avoid excess moisture. Call a contractor today to inspect and make sure you have the right ventilation levels.
