An improperly insulated and ventilated house can lead to air quality issues from mold and mildew and leaks caused by ice dams. This can lead to a variety of heath problems, such as sick home syndrome as well as serious water damage.
For many years it has been a common building practice to construct a roof system with two key insufficient insulation elements.
- Attic air ventilation of one square foot of open air ventilation for every 100 square feet of attic floor
- Attic floor insulation with a minimum of R-19.
Changes in construction have driven the need for significant insulation and ventilation
changes. Recent codes have increased the insulation requirements in new construction
for cold region climates to R-30 insulation or better. For example, Energy Star recommends
R-49 in the attic floor, in this region, combined with appropriate ventilation. When
installed properly, the insulation increases can help to save energy and reduce heating
and cooling costs. The ventilation requirements, unfortunately, are not as easily
defined, as there are many different roof designs and slopes, which require unique
tailored ventilation approaches for each. An experienced and trained roofer and insulation
expert can make all the difference.
Most roofers follow standard, but outdated practices that leave you with insufficient ventilation and air flow. Proper ventilation is critical to releasing any excessive heat that rises up from your heated living spaces in your home. Proper ventilation ensures that the air temperature inside the attic is as close as possible to the outside air temperature.
Improper ventilation and insulation, can cost you a lot to install, but still won’t
prevent an ice dam nor mold and mildew buildup. And this can affect your children’s
health by contributing to sick home syndrome? http://www.epa.gov/iaq/index.html
Ice dams were not a common problem in older homes because they were poorly insulated and as a result, very inefficient. As home construction and remodeling methods have changed and where making homes as air-tight and highly insulated as possible is the new mandate with highly efficient windows, increased minimums for insulation, insulated vinyl siding etc., conditions inside the home have changed. These new conditions in turn change the airflow dynamics and impact the ventilation and insulation requirements.
Many contractors will recommend added ventilation such as wind turbines, electro-mechanical ventilation, whole house fans, etc. These approaches are expensive and still may not solve the mold or ice dam problems, in fact some even make them worse. The homeowner is left with an inefficient home with ice dams and/or mold and mildew even though they have insulated, ventilated, installed new roofing, and painted and repainted their eaves and ceilings.
Mechanical ventilation, while necessary in some cases, may also cause your air conditioning units to run less efficiently because these high CFM (cubic feet of air per minute) fans draw the air from the space you are trying to keep cool. As the air is removed it needs to be replaced from lower levels of the home such as the basement or from outside air infiltrating through sill plates, windows, doors, electrical outlets and any other penetrations on the outside wall.
