Attic Ventilation: Louvers vs Ridge Vents

Louvers provide a solution to the attic ventilation problems in many homes. Attic ventilation is important because it facilitates proper maintenance of the roof. When temperatures are high during summer hot air accumulates at the attic. In addition, moisture generated by the home may easily find its way up to the attic. When such moisture condenses, it has a damaging effect on the construction material. Attic ventilation serves 2 purposes. It achieves temperature control and moisture control. The most efficient method in terms of cost and safety is natural ventilation. This occurs through use of air inlets and outlets. For best results, the air outlets should be located at the ridge while the air inlets should be located near the ceiling line. Use soffit vents and ridge vents for attic ventilation. Soffit vents come with a screen to keep insects out of the attic. They also have an aluminum panel with louvers to allow airflow.

Step 1 – Safety Procedures

Before you start the work of installing your vents, take time to ensure your safety while on the attic. It is advisable to put on loose garments with rubber-soled shoes. Rubber soled shoes help to avoid skidding on a slippery surface. You should only go up to the roof when the weather is calm and dry. Be careful where you tread. Look out for slippery shingles or rotten decking. Avoid power lines and television antennas. Pick up all the tools and materials you will need and deposit them on the attic.

Step 2 - Position Ladder

Position the ladder at an angle in relation to the wall so that you can access the top roof. Make sure it is secure and thereby avoid an accident.

Step 3 – Install Air Inlet

You may install your air vent anywhere near the ceiling line. Identify a good location between the rafters. Use the circular saw to cut a hole. Use a screwdriver to attach the vent to the soffit thereby covering the hole.

Step 4 – Install Ridge Vent

Extract the shingles to within 6 inches of the ridge or 1 foot from the chimney. Use a utility knife to remove the felt paper. Pull out the staples and the roofing nails. Use a chalk line on all sides of the ridge and use a circular blade to cut to a depth slightly thicker than the sheathing material. At this point remove any nails or pieces of the sheathing material that still remain.

Step 5 – Finishing the Job

Finally hoist the ridge vent on the peak. Begin the vent either at the end of the roof or at the slot.

Note:  Different ridge vent systems use different methods to maintain a cool environment on the attic.
