Can I Install New Siding over Old Siding?

If your home needs new siding, you may wonder if it can simply be installed over your existing siding, and the answer is that it’s complicated. The kind of siding you currently have and its condition will play a critical role in this equation. Before even considering having new siding installed over old, you’ll need to consult with a seasoned Pennsylvania siding professional at KSL Roofing and Remodeling.

Building Codes

Installing new siding over old siding is not considered an ordinary repair, which means you’ll need a permit as well as a professional inspection. Your local building department will need to greenlight your plan to install new siding over old, and you will need to address the matter with them before proceeding.

Another important consideration is asbestos. Some older homes still have asbestos siding, and it must be removed before new siding can be installed.

Your Current Siding

Before you think about covering up your old siding with new, you’ll need to have a solid understanding of what you’re working with. If your current siding shows signs of wear, such as any rotting, warping, or insect infestations, it must be removed and replaced. This helps to ensure that you have a solid base to work from and that your current issues won’t become even bigger problems over time.

If your siding shows signs of mold, mildew, or any other form of water damage, the best option is removing it prior to installing new siding. This allows you to locate the underlying problem and to adequately address it before installing your new siding, which is a significant investment.

Every instance of installing new siding over existing siding must be considered in relation to the unique specifics involved.
