Installing a Soffit Vent Instructions

  • Installing Soffit Vents

    Distorted and curled up shingles are often a sign of insufficient attic ventilation. Proper air flow is crucial to extend the life of your roof and help alleviate ice dams and attic condensation in the winter. Air flow will also reduce heat build up in the summer. Soffit vents allow fresh air into your attic while roof vents exhaust hot, humid air. You need to have equal intake and exhaust vents in order for attic ventilation to be effective,. Therefore, for every soffit vent, you also need a roof vent, or a ridge vent. Before you begin, be sure that you follow any precautions on your ladder.

  • Overview

    The basic steps to completing this project are to first, indicate the location of your new vent. Then, create a template, cut out a centered hole in the soffit, and finally install the vent and check your work.

  • Mark the Location

    From inside the attic, mark the location of your new soffit vents by following between the two rafters that are closest to your existing or planned roof vent. To mark the location of the soffit on the outside of your house, drill a hole through the pencil mark and poke a coat hanger out through the hole.

  • Choose the Soffit

    There are several types of vents to choose from. You can purchase rectangular vents, round vents or continuous vents that run the entire length of your soffit. Base your decision on the amount of ventilation you need and the size of your soffit. The installation procedures for each type are really the same, but you will need to cut a hole in your soffit that matches the vent you purchased.

  • Make a Template

    Before you install the soffit vent you need to make a template for the cut out. Cut out a template from cardboard or similar material with a hole directly in the center, which you will align with the hole you put into your soffit. The template should be one inch smaller than the actual length and width of your vent. This will allow a half-inch mounting surface all the way around the vent. Carefully position your ladder below the location of the soffit vent. Center the template over the hole that you made from inside the attic and confirm that each edge of your template is the square to the soffit. Trace around the template.

  • Cut the Hole

    Using the hole as the starting point, cut out the traced outline with a jig saw or reciprocating saw. Make sure you wear safety glasses to protect your eyes from falling sawdust. It is very easy to actually attach the soffit vent. Center the vent over the opening you just cut out and nail it or screw it into place. If nails were not provided, you can use galvanized roofing nails.

  • Check for Ventilation

    Check that you have adequate ventilation through your roof vent. Wet your finger and hold it up to the roof vent or light a match and blow it out close to the vent. If your finger feels cold or the smoke from the match goes out the roof vent, you should sufficient ventilation. If you feel that your ventilation is too slow, install additional soffit vents; or install an attic fan or a ridge vent.
