Roofing In Cambridge: Benefits Of Attic Air Sealing And Insulation


Homeowners can save serious money on HVAC costs with attic air sealing, attic insulation, and roofing in Cambridge and surrounding areas. If your home has an unheated attic space, you are probably losing quite a bit of the air you pay to heat and cool into that attic space no one is using. Conditioned air leaks out of your home’s living space through tiny spaces around your light fixtures, bathroom fans, chimneys and flues, and dozens of other places you would probably never have noticed. They call them thermal bypasses in the construction trade. Sealing thermal bypasses from living space to attic is an important first step in creating a more comfortable and energy efficient home.

Improving your attic insulation is the second vital step, because it keeps heat from transferring through the ceiling into your attic. When the attic air is warmed this way, it can melt the ice on the roof and cause ice dams to form, which can damage the roof material or cause leaks, which damage the structure of your home. Combining attic air sealing with improved attic insulation can eliminate ice dams for good.

The Benefits Keep Adding Up

In addition to saving you money on heating and air conditioning and extending the life of your roof an roof structure, what can attic air sealing and insulation do for you?

  • Improved Safety – A warm attic creates ice on your roof. And sometimes that ice slides off the roof. If you are lucky, it will only damage your landscaping. A properly insulated roof prevents dangerous ice from forming on your roof.
  • More Comfortable Environment – A home with a lot of thermal bypasses gets drafty. Really drafty. It also tends to have hot and cold spots in the living space, which make it impossible to adjust the entire house to a comfortable temperature.
  • Better Health –There are a lot of small ways that living in an improperly sealed house can affect your health. Allergens and germs are circulated more vigorously through your home when it is drafty. When there are hot and cold spots in the house, your heating and air conditioning have to run more, in order to try to keep up. Heating and air conditioning both dry the air significantly, and that dry air is tough on your skin and your respiratory system.
