What Are the Advantages of Installing Vinyl Siding Over Existing Vinyl Siding?

Extra Insulation

• Though vinyl siding doesn’t provide much insulation in and of itself, the layer of siding does have a slight impact on the amount of energy your home leaks. If you place a second layer on top of your current layer, you can double up this impact, insulating your home even more completely to keep the climate controlled inside without as much energy use.

Ease of Installation

• If you elect to place your new siding over existing siding, you remove one step in the vinyl siding installation process: stripping away the old siding. Placing your new siding atop your old is easier than first removing the original layer and then placing the new siding.

Error-Proof Coverage

• Especially if you are placing a new layer of siding that is the same color as the layer that rests below it, putting your fresh siding on top of existing siding can reduce the chances of noticing any gaps in your siding. Though you will work to minimize these gaps, from time to time gaps may show despite your efforts. If the layer that is visible in these gaps is another vinyl siding of the same color, it will be more difficult to spot these imperfections.

Pattern for Installation

• Leaving the vinyl siding that already coats your house in place can provide you with a pattern for new siding installation. If the siding is the same dimensions as the siding you are covering, this under-layer of siding can help you more easily line up your new siding pieces, creating uniform siding that is level and even without you having to constantly pick up your level or adjust your placement.
