While it would be nice if all house construction and improvement projects stayed on schedule, delays can lead to scenarios like a house sitting without siding for longer than intended. After 30 to 180 days of exposure to the elements, UV rays will compromise the house wrap and reduce its moisture protection. We break down reasons a house may sit without siding, factors that affect how long you can leave a house without siding, and the risks of delaying siding installation.
Why a House May Sit Without Siding
Construction delays are, unfortunately, a common occurrence that can throw off your intended schedule. Leaving a house with house wrap but without siding isn’t an ideal situation, but it’s an unavoidable one from time to time. Reasons a house may sit without siding include:
Delays waiting for materials or trying to locate discontinued siding
Waiting on a permit to install siding to be approved
Supply chain delays
Labor shortages
Bad weather

Climate and Weather
While you can’t always choose the best time of year to install siding to schedule your siding installation or replacement, the weather your home is exposed to before the siding is installed can significantly affect how long you can wait. Your house will be exposed to UV rays no matter the weather, but hot, sunny days may cause the house wrap to degrade faster. Extreme cold, wind, rain, or snow can also add to the urgency of installing siding as quickly as possible.
Type of House Wrap
House wrap is a water-resistant barrier made of synthetic materials that protects your house from moisture intrusion and is installed over the exterior of the house and underneath the siding. Different brands and types of house wrap can be exposed to the elements for different amounts of time—the manufacturer will have a guide to how long the wrap can offer UV protection.
Adding the cost of a house wrap with higher UV protection into your cost to replace siding or installing new siding can offer more peace of mind in the case of unexpected delays.
Risks of Letting a House Sit Without Siding
The longer a house sits without siding and is exposed to UV rays, the more compromised the house wrap will become. Risks of compromised house wrap include:
Reduced moisture protection
Higher chance of mold growth and rot
Energy loss
Compromised structural integrity
To avoid damage to your home’s exterior and an increased risk of mold and rot, hire a siding contractor who can complete the project in a timely manner without leaving your home exposed to the elements. A local siding pro can work with you or your general contractor to minimize delays and ensure your home stays protected. Finding a pro who installs siding in your area will help you determine the best time to install siding and to time the project right to reduce the risk of extended exposure.
