FAQs

Why is proper attic ventilation important during a roof replacement?

During a roof replacement, ensuring balanced intake and exhaust ventilation prevents heat and moisture buildup in the attic. Adequate airflow prolongs shingle life, reduces the risk of mold or wood rot, improves HVAC efficiency, and protects your new roof’s warranty—many manufacturers require proper ventilation for full coverage.

How does the climate in Soddy-Daisy affect attic ventilation needs?

Soddy-Daisy experiences hot, humid summers and mild, damp winters. High summer humidity can raise attic temperatures well above outdoor levels, stressing shingles and AC systems. In winter, moisture from daily activities can condense in a cool attic, promoting mold. A well-designed ventilation system tailored to our local temperature swings and humidity levels keeps the attic near ambient conditions year-round.

What types of ventilation systems can be installed when you replace my roof?

Common options include ridge vents paired with soffit vents, static box vents, powered attic fans, and gable vents. For most homes we install continuous ridge vents for exhaust and full-length soffit vents for intake, creating a natural convection flow. We’ll evaluate roof pitch, attic volume, and existing openings to recommend the optimal mix that meets or exceeds FHA’s 1:150 ventilation ratio.

How can I tell if my current attic ventilation is inadequate?

Warning signs include: shingles curling prematurely, excessive attic heat (feels like a sauna in summer), rusty roofing nails, damp or matted insulation, ice dams along eaves in cold snaps, musty odors, or visible mold on rafters. If you notice any of these, schedule an attic inspection before or during your roof replacement.

Will adding ventilation increase my energy bills in winter?

No. Proper ventilation removes moisture without significantly lowering attic temperature because most heat loss occurs through air leaks and insufficient insulation, not ventilation. By keeping insulation dry and preventing moisture-induced R-value loss, good airflow can actually reduce heating costs and improve indoor comfort.

Do local building codes in Soddy-Daisy require specific attic ventilation ratios?

Yes. Hamilton County follows the 2018 International Residential Code, which calls for a minimum of 1 square foot of net free ventilating area for every 150 square feet of attic floor space—or 1:300 when balanced between high and low vents. During your roof replacement, we calculate current NFVA and ensure your new system complies with these code requirements.
