FAQs
How does metal roofing affect attic temperatures in Farragut’s climate?
In Farragut, summer highs routinely hit the 90s, while winter lows can drop below freezing. A properly installed metal roof reflects much of the sun’s radiant heat instead of absorbing it like asphalt shingles. This keeps attic temperatures up to 30°F cooler on hot days, reducing the strain on your HVAC system. In winter, the same reflective surface paired with adequate insulation prevents heat loss, keeping your attic temperature more stable year-round.
Will a metal roof eliminate the need for attic ventilation?
No. Even though metal reduces heat gain, Farragut’s humid climate still produces moisture that migrates upward into the attic. Without balanced intake (soffit) and exhaust (ridge or gable) ventilation, that moisture can condense on rafters and decking, leading to mold and wood rot. A metal roof should be paired with at least 1 sq ft of net free ventilation area per 300 sq ft of attic floor (or 150 sq ft if a vapor barrier is absent).
Can radiant barriers be installed under a metal roof to further lower attic temps?
Absolutely. Many Farragut homeowners add a foil-faced radiant barrier or a reflective synthetic underlayment beneath the metal panels. This layer can block up to 97 % of radiant heat transfer, dropping attic temperatures another 5–10°F. Radiant barriers work best when there’s an air gap between the deck and the metal panels or when the barrier faces an enclosed air space.
How does attic insulation interact with metal roofing performance?
Insulation and metal roofing complement each other. The roof reflects heat; insulation slows conductive transfer into the living space. Farragut homes should have at least R-38 (about 12–14" of fiberglass or cellulose) on the attic floor. If you choose a ‘vented nail-base’ or ‘insulated standing-seam’ system, rigid foam above the deck can raise overall R-value to R-60, nearly eliminating thermal bridging at rafters.
Is condensation a problem under metal roofs in Farragut?
It can be if the assembly isn’t designed properly. Warm interior air that reaches the cool underside of metal panels can condense. To prevent this, we install a high-permeability synthetic underlayment with taped seams, maintain proper ventilation, and ensure attic humidity stays below 50 %. Optional panel-backing membranes with built-in condensation fleece are also available for extra protection.
Will a metal roof increase energy savings enough to offset higher upfront costs?
Most Farragut homeowners see summer cooling bills drop 10–20 % and winter heating bills about 5 %. Over a 40- to 70-year metal roof life span, energy savings plus avoided re-roofing costs often exceed the initial premium. Added benefits include lower insurance premiums due to Class 4 impact and Class A fire ratings, which further improve total return on investment.
