What to Know About Roofing Ventilation Before Winter Hits
As Iowa’s characteristically short fall rolls in, it’s only prudent to start thinking about the next season down the line: winter. None of us like even speaking the dreaded w-word, but it’s critical for your home exterior’s wellbeing that you get your seasonal prep-work done, even this far ahead of time.
One thing that often flies under the radar when it comes to that, though, is your roof and its ventilation. Though it may or may not require attendance at the moment, if it’s left ailing throughout the colder months, your home could suffer some serious structural damage.
Haggerty Windows & Siding, providers of roof replacement services and roof repairs, discusses the importance of proper roof ventilation below—and what can happen if it’s neglected.
The Basics on Roof Ventilation
Most roofs are designed to allow the air within them to “breathe.” This is accomplished via strategically placed vents that allow airflow without compromising watertightness. Functionally, it helps to prevent mold damage and keeps your home’s internal temperatures consistent.
Without these vents, humid air from day-to-day activities below—showering, washing the dishes, etcetera—moist air congregates in the attic, which creates the opportunity for fungus to set up shop. It also can, surprisingly, be a fire hazard, as dampness and nearby electrical wires don’t exactly mix. Finally, it can cause the metal fixtures in your roof to rust and deteriorate, opening up the door for structural strain and damage.
On the flip side, though, you also don’t want too much ventilation! That can lead to sky-high utility bills, as temperature-treated air just escapes through your attic.
Ice dams, for one, can result from improper roofing ventilation. Without a roof repair contractor to properly open up your attic space, warm air can melt the snow on your roof, which then refreezes as it rolls downward. This creates a dangerous backup of standing water that can wom its way under your shingles and cause dreaded wintertime roof leaks.
Ice formation in the roof Is also a commonly seen issue in improperly ventilated spaces. This might not seem like too big an issue at first—water can’t do much damage if it’s frozen, you might think—when that ice heats up, it soaks your attic through, reducing the efficiency of your insulation and even staining the ceiling below.
