When people see a house under construction, they often wonder: When is siding installed during the building process?
Siding installation typically happens after the structure of the home is framed and weather barriers are installed, but before exterior trim and finishing work is completed.
For homes in Collinsville, IL and throughout the Metro East area, siding plays an important role in protecting the home from weather while also improving curb appeal.
At Barringer Brothers Roofing, we install siding systems designed to protect homes from rain, wind, and seasonal temperature changes common in Southern Illinois.

What Happens Before Siding Is Installed?
Before siding can be installed, several important steps must be completed to prepare the home’s exterior.
These steps usually include:
• Structural framing of the home
• Installation of exterior wall sheathing
• Installation of a weather-resistant barrier (such as house wrap)
• Flashing around windows and doors
These layers help protect the structure from moisture and ensure the siding system performs properly.
Once these steps are complete, siding installation can begin.
Why Siding Is Important for Your Home
Siding does more than improve the appearance of a house. It serves as a protective barrier that shields the structure from weather and environmental damage.
Proper siding installation helps:
• Protect the home from rain and moisture
• Improve insulation and energy efficiency
• Prevent structural water damage
• Increase the durability of exterior walls
When siding is installed correctly, it helps extend the life of the home’s exterior and reduce maintenance issues.
Signs Siding May Need Replacement
Over time, siding can begin to wear down due to weather exposure and age.
Homeowners should watch for signs such as:
• Cracked or broken siding panels
• Warping or buckling siding
• Water stains inside the home
• Loose siding sections
• Fading or discoloration
If these issues appear, a professional inspection can help determine whether siding repairs or replacement are needed.
