FAQs
How much can a metal roof lower my summer cooling bills in McMinnville?
Because coated steel and aluminum panels reflect a high percentage of the sun’s radiant energy, homeowners here typically see a 10-25 % drop in July–September electricity use compared with an asphalt-shingle roof of the same color. On a 2,000 sq ft home this often translates to $150–$300 in annual cooling‐season savings, depending on insulation levels and thermostat settings.
What makes a metal roof cooler than traditional shingles?
Metal roofing products come with infrared-reflective pigments and granular finishes that bounce heat away instead of absorbing it. Unlike composition shingles, metal panels also cool off quickly once the sun sets, so attic temperatures drop faster at night. The result is less heat transfer into living spaces and reduced run-time for your AC unit.
Do I need a special “cool roof” coating for maximum savings?
Nearly all premium metal panels sold today already meet Cool Roof Rating Council (CRRC) requirements, but McMinnville’s warm, sunny summers make a high Solar Reflectance Index (SRI) worthwhile. Ask for panels with an SRI of 60 or higher (typically labeled “cool white,” “light gray,” or “bare metal”). If you prefer darker colors, select a Kynar 500/Hylar 5000 coating with IR pigments, which retains 30-40 % reflectance even in charcoal or bronze tones.
Will a metal roof make my attic hotter when temperatures hit the 90s?
No. In fact, thermal imaging shows attic sheathing under a vented metal roof stays 10-15 °F cooler at 3 p.m. than under dark asphalt shingles. Proper attic ventilation (ridge vent plus soffit intake) is still essential, but the reflective surface combined with the airspace under raised standing-seam ribs actually lowers peak attic temps.
Are there tax credits or utility rebates in Yamhill County for installing an energy-efficient metal roof?
Yes. Through 12/31/2032, the federal Energy Efficient Home Improvement Credit (IRC §25C) covers 30 % of the cost of ENERGY STAR-qualified metal roofing materials, up to a $1,200 annual cap. In addition, Portland General Electric customers in the McMinnville area can apply for a $0.25 / sq ft Cool Roof rebate when the SRI is ≥64. Always check current program rules before purchase.
How long will the energy-saving performance last in our rainy climate?
High-quality PVDF-coated steel or aluminum panels maintain at least 70 % of their original reflectivity after 20 years of Oregon weather. The smooth surface sheds moss, pollen, and debris better than shingles, retaining its cool-roof properties with minimal maintenance (an annual rinse with a garden hose is usually enough). Most manufacturers back fade resistance with a 30- to 40-year finish warranty.
