If you re-roof your house, it is the best time to ensure that your house’s attic ventilation is functioning correctly. All the moisture that’s naturally generated inside our houses by laundry, cooking, bathing houseplants, through open windows and doors toward the drier outdoors and other ways is trapped inside our homes. Unless your home features an excellent vapor barrier behind the ceilings and walls, which moisture subsequently winds up in the attic, when it isn’t correctly vented out of the loft, it condenses on cold surfaces inside your attic such as the bottom of the roof when nighttime temperatures fall. Condensation in a loft will eventually lead to mold and even rot — not extraordinary things!

Helps and Prevents ice dams

Finally, for people in northern climates, having excellent attic ventilation helps avoid ice dams on your roof. Heat leaks cause those damaging dams from the living space to the loft, melts the snow. That melted snow on the re-roof runs down the roof until it hits the cold overhangs where it re-freezes, forming an ice dam. Adequate ventilation in a loft will direct that warm atmosphere to your roof’s summit and then outside. Know more about ice dams.

How Great Ventilation Works

The vent spaces should be balanced 50-50 between exhaust and intake vents. If anything, you want to have marginally more intake than exhaust vents. Having more exhaust vents than intake vents may cause the exhaust vents to behave as combustion vents, drawing weather from the roof. Proper attic ventilation requires intake vents for fresh air and exhaust vents. Ventilation takes advantage of convective airflow (warm air rises) to keep bathing your loft with a new perspective, pushing the friendly, moist atmosphere.

Find the Right Roofing Contractor

Many individuals, including contractors, mistakenly feel that the heat-reflective finishes on today’s metal roofs, reduce attic ventilation demand. That is not correct. Ventilation should nevertheless be
performed per code. Inadequate or decreased venting, unless the home was specially constructed not to require ventilation, will result in higher energy costs, ice dams, and a massive threat of attic mold and condensation. Whatever sort of roof your home has, ventilation is essential.
