  • Roof style. Sometimes, the style of your roof influences the overall cost of installing a roof vent. For instance, flat, shed, and butterfly roofs are flatter and easier to work with, while gable and A-framed roofs have a steeper and more complex structure making installation more difficult.
  • Steepness. If you have a steep roof, the contractors will have to spend extra time and potentially use additional safety equipment to install the roof vent. In this case, your costs will increase.
