FAQs
Why is proper attic ventilation so important for homes in Jellico?
Jellico experiences hot, humid summers and cool, damp winters. Without balanced intake and exhaust ventilation, trapped heat and moisture can reach 150°F in summer, baking shingles from beneath, raising cooling costs, and fostering mold. In winter, warm interior air that escapes into an under-ventilated attic condenses on cold roof decking, causing rot and ice dams. A code-compliant ventilation system keeps temperature and humidity near outdoor levels year-round, protecting shingles, framing, insulation, and indoor air quality.
How do you determine the right amount of ventilation for my attic?
We follow the International Residential Code (IRC) 1:300 rule: 1 sq ft of net free ventilation area (NFA) for every 300 sq ft of attic floor space when a balanced system with vapor barrier is present. First, we measure your attic’s square footage, then calculate total NFA required. We split that 50/50 between intake (soffit or lower-roof vents) and exhaust (ridge or roof-mounted vents). We also factor in Jellico’s wind zone to ensure vents meet uplift resistance requirements and use manufacturer NFA ratings to select the right number and style of vents.
What types of ventilation products do you install?
For exhaust, ridge vents are our first choice because they run the entire roof peak, providing continuous, low-profile airflow. If the roof design prevents a full ridge vent, we install static roof louvers or power vents with humidistats. For intake, we prefer perforated aluminum or vinyl soffit panels paired with SmartVent in areas lacking soffits. Every product we use is Miami-Dade/TAS-100 certified for wind-driven rain, ensuring durability in Jellico’s spring storms.
Will adding more vents ever cause roof leaks?
Not when installed correctly. We use manufacturer-approved flashing kits, ice- & water-shield underlayment around all cuts, and stainless or hot-dipped fasteners. Ridge vents are secured with corrosion-resistant ring-shank nails and covered by cap shingles. Each penetration is sealed with high-grade polyurethane, and we photograph every step for your records. Our "Roofing Done Right" warranty covers workmanship for 15 years, so if a leak occurs, we fix it free of charge.
How long does an attic ventilation upgrade take, and will it disrupt my household?
A typical single-family home in Jellico needs 4–6 hours for a ridge-vent retrofit and soffit-vent installation. We start after 8 a.m., finish before dinner, and leave your attic insulation undisturbed. Our crew uses catch-all tarps to protect landscaping and magnetic rollers to remove nails. You can stay home the entire time; electricity and HVAC remain on. We perform a blower-door exhaust test afterward so you can immediately see the airflow improvement.
What is the cost and return on investment (ROI) of improving attic ventilation?
Cost depends on roof size, pitch, and vent style, but most Jellico homeowners spend $850–$1,700. TVA energy-efficiency studies show that balanced ventilation combined with proper attic insulation can cut cooling costs by up to 15 %. Many customers recoup the project cost in 3–5 years through lower energy bills, extended shingle life (adding 5–10 years), and fewer moisture-related repairs.
