In this guide, we’ll walk you through the process of replacing plywood on your roof.

1. Why Do You Need to Replace Plywood on a Roof?
Plywood on a roof serves as the foundation for your shingles and roof covering. Over time, weather conditions, moisture, and wear can cause the plywood to warp, rot, or degrade. Here are common reasons you might need to replace plywood on your roof:

Water Damage: Leaks that have caused the plywood to rot.

Age: Plywood deteriorating over the years due to exposure to elements.

Storm Damage: Severe weather or high winds that may have caused damage to the roof structure.

2. Signs That Your Roof Plywood Needs Replacing
Identifying the right signs of damage will help you decide whether replacing plywood is necessary. Some signs include:

Visible Holes or Rot: Look for soft or spongy areas on the roof.

Sagging Roof: A sagging roof may indicate a weak plywood foundation.

Leaks: Persistent leaks inside your home are often a clear sign that your plywood may be compromised.

3. Tools and Materials You’ll Need
Before you begin, make sure you have all the necessary tools and materials:

Ladder

Pry bar

Hammer

Circular saw

Replacement plywood

Roofing nails

Safety equipment (gloves, goggles, harness)

4. Safety Precautions
Safety should always be your top priority when working on a roof. Some important safety tips include:

Always use a stable ladder and ensure it’s on a flat surface.
