The question of whether to vent the roofing in a residence has only recently become a common one. Standard ventilation is still the most popular choice overall, but homeowners are seeking more varied roof formations that can sometimes make vent setup prohibitively difficult. To work around these complications and capitalize on an appealing set of benefits, some new and existing homeowners are opting to hire professional roofers to seal their Summerville roofing and attic spaces entirely.
An unvented roof assembly is constructed with the goal of an airtight boundary between the attic and the outside world. The soffit and ridge vents included in conventional roofs are omitted completely in newly constructed unvented roofing. Insulation in this setup is typically applied to the attic ceiling from the roof deck peak to the top edge of the walls and anywhere else that may leave an opening instead of the ceiling directly below the attic.
The International Residential Code has determined the specific R-values that an unvented assembly should be required in South Carolina to successfully prevent condensation and meet the IRC standard for energy efficiency. Condensation prevention only requires material with an R-value of 5 thanks to the relative heat of the area. An R-value of 30 is needed to establish an efficient energy pattern.
When built by skilled and knowledgeable professionals, homeowners are often highly satisfied with sealed roofing, particularly in a hotter climate such as that of South Carolina.
