FAQs
How do energy-efficient metal panels reduce heating and cooling costs in Gruetli-Laager’s climate?
Our panels are manufactured with high-reflectivity paint systems that bounce a large portion of the sun’s infrared radiation away from the roof or wall surface. In a warm, humid summer like Gruetli-Laager typically experiences, this reflectivity can lower attic and interior temperatures by 10–15 °F, easing the load on your air-conditioning system. During winter, the integrated, tight-fitting seams and optional insulation backers minimize heat loss caused by wind infiltration. Homeowners generally report 10–25 % annual savings on energy bills after upgrading to our metal roofing or siding.
What profiles and coatings are available, and which options are best for my home or business?
We stock standing-seam, corrugated, and concealed-fastener panels in gauges from 24 to 29. For residential applications, 26-gauge standing-seam in a Kynar 500® (PVDF) coating is most popular because it combines sleek curb appeal with superior color retention. Light-commercial and agricultural buildings in Gruetli-Laager often choose 29-gauge corrugated panels with a silicone-modified polyester (SMP) coating for cost-effectiveness. All profiles can be ordered with Cool Roof certified colors that meet ENERGY STAR® reflectivity standards.
Will a metal roof be noisy during rain or hail, and how is sound controlled?
When installed over solid decking with an approved underlayment, a metal roof is only 2–4 dB louder than an asphalt roof—about the difference between an indoor conversation and a soft whisper. For extra sound dampening, we offer high-density foam or mineral-wool insulation that fills the air cavity beneath the panels. Most customers find that interior noise is comparable to, or quieter than, their previous shingle roof once these measures are in place.
How long do your metal roofing and siding panels last, and what warranties are included?
The corrosion-resistant Galvalume® steel substrate carries a manufacturer’s warranty of up to 45 years. PVDF paint finishes are warranted for 30 years against fading and chalking, while SMP finishes are covered for 20 years. In practical terms, you can expect a service life of 50+ years with minimal maintenance—more than double the lifespan of traditional asphalt shingles or wood siding.
Can your panels be installed over an existing shingle roof, and what is the typical installation timeline?
Yes. Local building codes in Grundy County allow metal roofing to be installed directly over up to two layers of asphalt shingles, provided the decking is sound. This saves tear-off costs and reduces landfill waste. A standard 2,000 sq ft residence can usually be re-roofed in three to five days, weather permitting. Siding jobs of similar square footage typically take four to six days because of additional trim and flashing work.
Are metal panels environmentally friendly, and can they help me qualify for energy rebates or tax credits?
Absolutely. Our panels contain up to 35 % recycled steel and are 100 % recyclable at end of life. The Cool Roof coatings can reduce urban heat-island effect and may qualify for TVA’s EnergyRight® incentives or the federal Residential Clean Energy credit, which currently offers up to a 30 % tax credit on qualified installations. We provide all necessary reflectivity and emissivity documentation to help you complete rebate or tax credit applications.
