How to install a roof vent

When it’s time to install a roof vent, the process is relatively simple if you don’t overthink it.

Roof vents are a must when installing or repairing a roof. The air in houses is filled with moisture and roof vents allow a place for that moisture to escape. This prevents rot, decay and mold and mildew buildup. After you’ve determined how many roof vents you’ll be installing and where on the roof you’ll be putting them, the next step is to get that thing installed.

Here’s how to install a roof vent:

The tools needed are

  • Hammer
  • Screw gun
  • 4″ hole saw
  • Caulk gun
  • Nail bar
  • Utility Knife with hook blade


Mark your spot:

To begin, get in your attic and put a screw all the way through the roof so you know where you’ll be putting the roof vent.
