For many people, learning how to install vinyl soffit over wood isn’t necessarily something they think about regularly. Most people take their roof and all that goes along with it for granted. After all, your roof tends to last for decades with minimal upkeep and maintenance from you. New construction homes can go even longer between repairs because they are often made with more durable products than those used in older homes.

Vinyl is one of the newer materials that has helped the home construction industry in leaps and bounds. It is an excellent material to use, particularly when compared to the wooden pieces that tend to rot with exposure to the elements over time. The truth is that your home could probably benefit from the new vinyl soffit.

The argument for vinyl soffits and fascia is relatively clear. Not only is it an affordable option, but it is also one of the best materials for insulating the home. It comes in a wide array of design choices so that it’s easy to find something that matches the look and feel of your home. Unlike wooden soffits, vinyl is both water-resistant and impervious to rot. It can also be much simpler to clean between seasons.

Proper Ventilation with New Vinyl Soffit

If you happen to be working on an older home, most contractors and homeowners find that they will need to install their vinyl soffit over top of old wood. This can definitely be done, but you will need to take several precautions to prevent the wood from rotting beneath this new layer. First and foremost, you need to ensure that there will be adequate ventilation based on the size of the attic.

The proper amount of ventilation can vary based on the size of your attic and the climate of your particular area. You will want to consult your local building codes before moving ahead with installing the new vinyl soffit.

Many people find that perforated siding is sufficient for their ventilation needs. Because some manufacturers do make vented soffit, you might not need to make many changes to the existing structure in order to install vinyl soffit over the plywood.

However, it is considered standard practice to cut holes in the existing plywood to direct more airflow into the attic space before covering it with vinyl. Planning to install vinyl soffit over plywood means planning to improve these areas of ventilation. You will likely need to cut a hole in the plywood every few feet to meet the building codes for your unique area.

Installing Vinyl Fascia Over Wood

Fascia board is equally important when it comes to the construction of your home. This is the horizontal board that runs along the edge of the roof, allowing you to attach both gutters and soffit panels. Older homes mostly have wood fascia, but many homeowners wish to upgrade this to a vinyl product that is more durable and long-lasting as well.

Vinyl fascia is considered by most individuals to be more visually appealing than painted wood. However, it also serves a more practical function. Installing vinyl fascia over plywood helps to protect the wooden structure that is currently in place.

Installing the fascia is relatively simple.

  1. Remove all of the gutters and downspouts from your home.
  2. Place a J-channel along the wall and nail it to the underside of your soffit plywood every foot and a half.
  3. You will then cut the new vinyl soffit pieces and slide them into the J-channel, nailing the opposite side into the wooden fascia board. This should hold the soffit in place until you can install the fascia.
  4. Cut your fascia pieces and tuck the top of the drip edge between your shingles and the plywood on the roof.
  5. Nail it approximately one inch from the top of the new vinyl fascia and finish by reinstalling the gutters.

It may take some time to follow all of these instructions, but none of them are too terribly complicated. With a little bit of time and some knowledge of measuring and making cuts, you can easily figure out how to install new vinyl soffit and fascia.

Installing Vinyl Soffit and Fascia

While it is certainly feasible to install vinyl fascia and soffit over wood, you need to ensure that you are keeping in line with the local building codes. Make sure that your attic has enough ventilation before affixing your vinyl soffit over the plywood.

Taking care of these important details upfront will save you from having major issues with your home in the future. Learning how to install vinyl soffit over wood is an important skill to help you improve the look and functionality of your home.
