How Do You Replace Damaged Roof Sheathing?

Roof sheathing, also called decking, is one of the most important components of a roofing system. It provides the solid base that supports shingles, underlayment, and other roofing materials. When sheathing becomes damaged, it compromises the strength of the roof and can lead to leaks, sagging, or even structural issues. For homeowners in West Mifflin, PA, replacing damaged roof sheathing quickly is essential to maintaining a safe and durable roof.

What Causes Roof Sheathing Damage?

Several factors can weaken roof sheathing over time:

• Moisture Intrusion: Leaks from damaged shingles or flashing can cause plywood to rot or warp.

• Pests: Insects or small animals can nest in or chew through sheathing.

• Age: Older homes may have sheathing that has weakened simply from years of exposure to changing weather.

• Improper Ventilation: Trapped heat and moisture in the attic can damage sheathing from underneath.

  
  

When any of these issues arise, the sheathing must be inspected and replaced to prevent further problems.

Steps to Replacing Damaged Roof Sheathing

Replacing roof sheathing is not a small task, but understanding the general process helps both homeowners and contractors know what is involved.

1. Remove Roofing Materials Shingles, underlayment, and nails are carefully removed in the area where sheathing is damaged. This step exposes the plywood and makes it easier to inspect.

2. Inspect the Sheathing Contractors identify which sheets of plywood need to be replaced. Sometimes the damage is limited to a small section, while in other cases, larger areas may need attention.

3. Cut and Remove Damaged Sections The damaged plywood is cut out and removed. This requires precision to avoid disturbing surrounding materials that are still in good condition.

4. Install New Plywood New sheathing panels are measured, cut, and secured into place. Contractors use nails or screws to fasten the plywood to the roof trusses or rafters, ensuring a stable base.

5. Re-Install Roofing Materials Once the new sheathing is in place, underlayment and shingles are reinstalled. Contractors pay close attention to sealing the area properly to prevent future leaks.
