FAQs
What exactly are standing-seam metal panels, and how do they differ from traditional metal roofing?
Standing-seam panels are long, vertical metal sheets joined together with raised interlocking seams that conceal the fasteners. Unlike ribbed or exposed-fastener metal roofs, all screws and clips are hidden beneath the seams, giving the roof a sleek appearance and preventing potential leak points. This concealed-fastener design also allows the panels to expand and contract with Oakdale’s temperature swings without stressing the metal or fasteners.
How long can I expect a standing-seam metal roof to last in Oakdale’s climate?
With proper installation and minimal maintenance, a standing-seam metal roof typically lasts 40–70 years in Oakdale. The panels are fabricated from galvanized or Galvalume steel or aluminum, all of which resist corrosion, high summer temperatures, and the occasional heavy winter rain. Factory-applied Kynar or SMP paint finishes further protect the metal from UV breakdown, helping the roof retain its color and structural integrity for decades.
Are standing-seam metal roofs energy-efficient for Oakdale homes and businesses?
Yes. The raised seams create a continuous metal surface that reflects a significant amount of solar radiation, lowering attic temperatures and reducing cooling costs during Oakdale’s hot, dry summers. Many panels are ENERGY STAR® rated and available with cool-roof coatings that meet California Title 24 requirements. Homeowners often see a 10–25 % reduction in energy usage after upgrading from asphalt shingles to standing-seam metal.
How much upkeep does a standing-seam metal roof require?
Maintenance is minimal. We recommend a visual inspection each spring and fall, removing any debris from valleys and gutters, and checking for sealant wear around rooftop penetrations such as vents or skylights. Because fasteners are concealed, you don’t need to retighten screws the way you would with exposed-fastener panels. Periodic cleaning with a garden hose and mild soap will keep the paint finish looking fresh.
Will a metal roof make my home noisier during Oakdale’s infrequent rainstorms or hail?
Not if it’s installed correctly. A standing-seam roof sits atop an underlayment and often a solid roof deck. Together with attic insulation, these layers dampen sound so effectively that indoor noise levels are comparable to or quieter than what you’d experience with composite shingles. If extra sound absorption is desired, we can add high-density acoustic underlayment at a modest cost.
Can standing-seam panels be installed over my existing shingle roof, or does the old roof need to be removed?
In many cases we can install over one layer of asphalt shingles, saving disposal costs and shortening project timelines. We’ll first inspect the decking for structural integrity, confirm local code compliance, and add a slip-sheet or synthetic underlayment to prevent shingle granules from abrading the metal. If your current roof has two or more layers, significant water damage, or an uneven surface, full tear-off is recommended to ensure the new standing-seam system performs to its 40-plus-year lifespan.
