How Can An Improper Ventilation System Cause Damage To My Roof?
It is the moist attic air that can cause the most damage to the structural integrity of your roof. Without proper ventilation, moist air collects on the underside of the roof decking and can cause the decking and attic insulation to expand slightly. As the wood dries out, it contracts. If your home was built without the use of deck spacer clips, this cycle of expansion and contraction can cause the wood to warp over time or lead to premature wood fatigue.
