Attic & Roof Ventilation

Attic and roof ventilation is the system of intake and exhaust vents that keeps air flowing through your home's upper structure, helping regulate temperature and prevent moisture buildup. Proper ventilation protects your roof from premature aging, reduces energy costs, and keeps mold at bay.

Common Attic & Roof Ventilation Questions

Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

No, you do not need gable vents if you have a ridge vent. In fact, gable vents would actually interrupt the process that ridge vents are set to conduct. You would be better off to decide between the two depending on your home’s needs.

No, ice dams aren’t a standalone sign that you need a new roof. Ice dams can form on new roofs, as issues with the insulation inside your home are often the underlying problem. However, if you notice signs of roof damage from ice dams, you might need to hire a local roofer for repair or partial replacement.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

Roof raking helps clear snowfall from your roof and, in turn, you hope that this prevents ice dams. But can roof raking actually cause them? Generally, no, it cannot. But you should note that while, in some cases, you might successfully prevent ice dams from forming near the edge of your roof by keeping it cleared with a roof rake, they could still form higher up on the roof, where you are unable to reach. This may leave you wondering: Does roof raking prevent ice dams? While it is not a 100% guaranteed way to prevent them, it does help.
