Attic Defects

Missing collar ties(this is done to prevent rafters from spreading apart under load and help hold the ridge assaembly together) Rafters not sistering properly which will not maintain the structural integrity.

Wood rot can and will start when the moisture content of the wood reaches 20 percent. But wood rot is a slow process where the fungi start to grow and feed on the cellulose in the wood. The wood needs to remain damp and wet all the time for wood rot to advance.

A bathroom vent can run through an attic. This warm moist air should go in the most direct path possible and have continuous insulation to prevent condensation and water damage.

Missing attic insulation is one of the most common—and most costly—problems in cold‑climate homes. Since you work in Ajax and the surrounding areas, you see firsthand how Ontario winters expose every weakness in a building envelope. When insulation is thin, patchy, or completely absent, the house starts telling on itself in very predictable ways. Why Missing Attic Insulation Is a Big Problem in Cold Areas 1. Massive Heat Loss 2. Ice Dams and Roof Damage 3. Condensation and Moisture Problems 4. Uneven Temperatures Throughout the Home 5. Reduced HVAC Lifespan 6. Poor Indoor Comfort 7. Higher Energy Bills 8. Lower Home Value
