Did you know that 90% of the homes in the Portland Area are wasting 30% of their energy due to improperly ventilated roofs?
An under ventilated attic will retain moisture. Just a 2% increase in humidity will cause your attic’s insulation value to drop by 30%!
Improper ventilation is a leading cause of premature failure in roofing today. Improper ventilation creates many problems for homeowners in the Portland Area:
Higher Cost of Heating/Cooling Bills
More wear on HVAC system
Less life span and loss of value to your roof
Toxic mold and mildew that can cause allergies, respiratory issues, and other ailments
Structural damage to your roofing system unseen to the homeowner
When air enters your home it rises to the attic space and can become confined. Improperly vented homes trap air and moisture, causing a reduction in your insulation’s value (R-Value). In addition, this trapped moisture will cause premature agin of your roof and deterioration of your roof structure. Causing the homeowner concerns with long term monetary stress and possible health issues.
Proper ventilation in your home occurs when the air exchange is equal. This gives your home the chance to breathe and expel heat in the summer and moisture in the winter. Remember also that construction has become efficiency focused; using house wraps and sealants around windows and doors. These home wraps force all moisture in the home to travel upward into your home’s attic space, increasing the need for higher ventilation standards.
Every roof inspection we do we are checking the ventilation to be sure your home will be working in it’s best condition.
