eco-system. Poorly ventilated soffits, lack of vapor barrier, and improperly insulated attics can cause serious problems to your roof deck and your shingle system (new or existing). Your roof deck could expand and contract causing your shingle system to buckle and curl as well. These factors can also contribute to attic condensation and interior leakage, especially during freeze-thaw cycles. It may appear as if your roof is leaking, when in fact it is interior condensation. These same factors can also contribute to ice damming. Please refer to www.airvent.com for more information on proper ventilation or inquire your TCR representative for more details.
