What Good Attic Insulation Means for Your Roof

In its own way, the attic insulation does an effective job at keeping your roof system healthy and well-performing. But how exactly does good attic insulation do it? The premier residential roofing specialist in the area, M&A Exterior Home Improvement, shares what you need to know. 

Stops Ice Dams From Forming

The climate in Virginia may be milder than in other regions, but there are days when it does get cold, sometimes accompanied with snowfall. This type of weather may prompt you to switch on your furnace — except some of that valuable heating energy may leak into the attic. This is where good attic insulation (along with proper ventilation) comes into play. It prevents warm air from building up in the attic and creates a ‘hot’ roof surface. A hot roof causes snow and ice to melt down and refreeze along the eaves. This results in ice dams, which can wreak havoc on your roof and create leaks. But with good attic insulation, this shouldn’t be much of a problem. That’s because it helps keep your roof cool by keeping the attic temperature stable.

Prevents Mold Growth in the Roof Structure

Good attic insulation doesn’t just stop ice dam formation — it can also reduce the potential for mold growth inside the attic. Working in tandem with the attic ventilation, good insulation prevents warm and moisture-laden air from ending up inside the attic. That’s because excess heat and moisture are in the same space as wood or wood composite (the material used for the roof decking and trusses) encourages mold growth. By heading off this issue, good attic insulation ensures that your roof structure will remain sturdy and intact.

How well your attic insulation performs will depend on its quality and type. Attic insulation is available in several different options. If you have trouble choosing which one to install your attic, just consult M&A Exterior Home Improvement. We’ll be more than happy to help you explore your options and decide on the attic insulation that best suits your needs and budget.
