It's no wonder that architechural shingles in coastal South Carolina don't last as long as the manufacturers' claims; with the unbearable heat we have in Charleston a roof's life span is pushed to the limit. However, with proper attic and roof ventilation you can prolong the life of your roof while at the same time increase the energy efficiency of your home. During warmer months, ventilation helps keep attics cool. It helps prevent hot, moist summer air from warping the roof sheathing. It also stops shingles from deteriorating prematurely. What's more, fresh air in the attic makes a home much easier to cool, which can result in lower energy costs. In winter months ventilation helps reduce moisture to keep attics dry. It stops water from backing up under shingles, damaging insulation, and rotting the roof structure itself. If you'd like an attic and roof inspection and live in Mount Pleasant, Isle of Palms, Sullivans Island, Daniel Island, or the surrounding areas of the tri-county please contact us.
Here are the results done by third party research trial (paid for by AirVent) where an unbalanced poorly or non-ventilated home in Texas had proper balanced 50 In-50 out attic ventilation installed. 98 Degree day.
Maximum roof deck temperatures dropped from 146.5°F to 124°F (-22.5°F).
• Maximum attic temperatures dropped from 123.2°F to 113.9°F (-9.3°F).
• Maximum interior surface temperatures dropped from 83.1°F to 76.7°F (-6.4°F).
• Kilowatt Hours dropped from 130 to 104 (-20%). A 20% reduction in electrical bill can be over $500+ year in savings.
