When it comes to preparing the roof for the winter season, most people look at the roof’s surface and the gutters. They check if shingles are out of place and if the gutter will be safe from ice dams, but that doesn’t mean other parts of the roof doesn’t need attention. Home improvement experts say that this is especially true for roof and attic ventilation because of a number of key reasons.
Good roof and attic ventilation ensures that air will keep flowing in and out of the roof. This will significantly reduce the chances of condensation on surfaces of the roof that might be vulnerable to moisture damage. In short, you get to air out the roof before rust and rot starts becoming a major issue.
Shingles are designed to withstand the harsh winter elements. However, a poorly-ventilated roof can cause the bottom side of the shingles to be warmer than its surface. This imbalance in temperature can cause problems like shingles curling or popping, which can compromise the roof. With good ventilation, shingles will have a more consistent temperature less likely to get damaged.
Damp, poorly ventilated roofs are prime breeding grounds for mold and mildew colonies. Aside from these colonies releasing spores that can cause respiratory irritations, they can also create dark spots in the ceiling that can be very difficult to remove. Keeping the roof and attic ventilated and dry will go a long way in preventing mold and mildew-related issues.
Poor ventilation (along with improper insulation) can cause “hot spots” to occur throughout the roof’s structure. These spots where warm air from indoors can’t properly circulate can melt the snow on the other side of the roof. Snowmelt can freeze back into solid ice, which can lead to the formation of damaging ice dams that have to be removed with help from certified roofing contractors.
