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.

A skilled DIY enthusiast will likely have minimal trouble installing their own attic fan. Solar and passive attic fans require no electrical wiring work, making the project reachable for intermediate DIYers as well.

However, be sure you have the knowledge and skills to prevent leaks before starting. Should anything go awry, prepare to pay for attic fan repair costs, which range between $200 and $450.
