    Roof Decking & Plywood Replacement

    Roof Decking & Plywood Replacement in Wasaga Beach & Simcoe County

     

    705 Roofing provides professional roof decking and plywood replacement services for damaged, weakened, or rotting roof structures. A strong roof deck is critical for the performance, lifespan, and safety of your entire roofing system.

     

    If your roof has soft spots, leaks, sagging areas, or water damage, damaged plywood may need to be replaced before a new roofing system is installed.

    What Is Roof Decking?

    Roof decking is the wood surface installed over the roof framing that supports the roofing system.

    Most residential roofs use:

    • Plywood
    • OSB (Oriented Strand Board)

    Common Causes of Roof Deck Damage

    Roof decking can become damaged due to:

    • Moisture buildup
    • Poor ventilation
    • Ice damming
    • Aging roofing systems
    • Mold and rot
    • Structural movement

    Damaged decking should be replaced before installing new shingles or metal roofing.

    Signs Your Roof Decking May Be Damaged

    You may have damaged plywood or roof decking if you notice:

    • Soft spots on the roof
    • Sagging roof areas
    • Interior water stains
    • Mold or moisture in the attic

    In many cases, decking damage is hidden beneath old shingles and only becomes visible during roof replacement.

    Our Roof Decking Replacement Process

    1. Roof Inspection & Tear-Off

    We remove the existing roofing materials and inspect the roof deck thoroughly for damaged or weakened areas.

     

    2. Damaged Wood Removal

    Rotten, soft, or deteriorated plywood and decking materials are removed safely.

     

    3. New Decking Installation

    New plywood or roof decking is installed securely to create a solid foundation for the roofing system.

     

    4. Roof System Installation

    Once the decking is repaired, we install:

    • Ice and water shield

    • Underlayment

    • Roofing materials

    Why Proper Roof Decking Matters

    A weak roof deck can lead to:

    • Shingle failure
    • Roof leaks
    • Structural issues
    • Sagging roof sections
    • Reduced wind resistance
    • Premature roof deterioration

    Proper decking replacement helps ensure a longer-lasting and safer roofing system.

    Roof Deck Repairs During Roof Replacement

    During roof replacement projects, it’s common to discover hidden decking damage after shingles are removed.

    We believe in fixing the roof properly — not covering damaged wood with new shingles.

    Roof Ventilation & Moisture Protection

    Excess moisture trapped inside the attic can lead to:

    • Mold growth
    • Wood rot
    • Condensation damage
    • Premature plywood deterioration

    We inspect ventilation systems during roofing projects to help prevent future moisture problems.
