FAQs
What are standing-seam metal roof panels and how do they differ from other metal roofing profiles?
Standing-seam panels are long, vertical metal sheets whose edges interlock with a raised seam that sits 1–2 inches above the roof deck. Unlike exposed-fastener panels (such as corrugated metal) where screws penetrate the face of the panel, standing-seam systems hide all fasteners beneath the seams or clips. This design creates a continuous, watertight surface that better resists leaks, expands and contracts without stressing the fasteners, and delivers the clean, modern lines many Winfield property owners prefer.
How long can I expect a standing-seam metal roof to last in Winfield’s climate?
With proper installation and minimal upkeep, a standing-seam metal roof typically lasts 40–70 years in the Midwest. Galvalume or aluminum panels resist rust, wind-driven rain, hail, and freeze–thaw cycles far better than asphalt shingles, which often need replacement after 15–25 years. Most manufacturers back the metal with 30- to 40-year paint warranties and limited lifetime warranties on the substrate, giving Winfield homeowners long-term peace of mind.
Will a metal roof make my house noisier during heavy rain or hail?
When a standing-seam roof is installed over solid roof decking (plywood or OSB) with underlayment and attic insulation—standard practice in Winfield residential projects—indoor sound levels are comparable to or slightly quieter than those of an asphalt-shingle roof. The combination of rigid decking, synthetic underlayment, and attic insulation absorbs much of the impact noise. If you desire even more sound dampening, a thin acoustic membrane can be added beneath the panels.
How energy-efficient are standing-seam metal roofs?
Metal reflects a large portion of solar radiation instead of absorbing it like dark shingles. Many standing-seam finishes carry ENERGY STAR® ‘cool roof’ ratings, meaning they reflect at least 25–65 % of the sun’s heat. In summer, that can lower attic temperatures by 10–20 °F and cut cooling costs by up to 20 %. In winter, the tight seams and continuous panels minimize heat loss from wind-driven infiltration. Some Winfield homeowners pair metal roofing with above-sheathing ventilation or a radiant barrier to maximize efficiency.
Can standing-seam panels be installed over my existing shingle roof?
Yes—provided the current roof deck is flat, dry, and structurally sound. Building codes in DuPage and Kane Counties allow one existing layer of shingles to remain if local weight and fire regulations are met. We place a slip sheet or synthetic underlayment over the shingles, then attach the concealed clips and panels. Re-roofing saves tear-off disposal costs and shortens the installation timeline. However, if there are soft spots, rot, or more than one layer of shingles, a complete tear-off is recommended.
What routine maintenance does a standing-seam metal roof require?
Maintenance is minimal: 1) Rinse leaves or debris from valleys and gutters each spring and fall to ensure unobstructed water flow. 2) Inspect sealant at flashings, skylights, and roof penetrations every 3–5 years; re-caulk if it shows signs of cracking. 3) After extreme hail or high-wind events common in the Winfield area, do a visual check for denting or displaced ridge caps. Because the fasteners are concealed, there are no exposed screws to retighten periodically—one of the key advantages of standing-seam metal roofing.
