FAQs
What advantages does standing-seam metal roofing offer Kelso homeowners versus other roofing materials?
Standing-seam metal panels are formed from heavy-gauge, corrosion-resistant steel or aluminum that is joined with raised vertical seams, creating an exceptionally watertight, wind-resistant surface. In Kelso’s wet climate, the concealed fasteners eliminate the exposed nail holes that can allow moss, moisture, and wind-driven rain to penetrate asphalt shingles. Metal reflects solar radiation, lowers summertime attic temperatures, and is non-combustible for superior fire safety. With a service life of 50–70+ years, minimal maintenance, and the potential for insurance discounts, it is a long-term upgrade that typically pays for itself over time.
How long can I expect a standing-seam metal roof to last compared with an asphalt shingle roof?
In the Pacific Northwest, a quality architectural asphalt shingle roof averages 18–25 years before significant granule loss and leaks appear. A properly installed standing-seam metal roof, however, routinely performs for 50 years and often exceeds 70 years thanks to its rust-inhibiting coatings and robust panel interlocks. The panels resist cracking, curling, and UV degradation, meaning you are likely to reroof once—possibly never again—over the life of the home.
Will a metal roof make my home louder when it rains or hails?
No. When installed over solid roof decking and underlayment, a standing-seam metal roof is no noisier than traditional shingles. The plywood or OSB deck, synthetic underlayment, and attic insulation all absorb sound. Many homeowners report less noise than with their previous roof because metal’s rigid panels dampen vibration, and there are no loose tabs to flap in high wind.
Is standing-seam metal roofing energy-efficient for Kelso’s mixed climate?
Yes. Metal reflects a large percentage of the sun’s radiant heat, reducing summer cooling costs by 10–25 percent. In winter, the panels shed snow quickly, preventing ice dams and keeping attic insulation dry so it performs at full R-value. We also install an optional high-temperature synthetic underlayment that adds another thermal break. Several colors are ENERGY STAR® rated and may qualify for utility or tax incentives.
What does a standing-seam metal roof replacement cost in Kelso, and what factors affect the price?
Installed pricing in Cowlitz County typically ranges from $9 to $14 per square foot ($900–$1,400 per roofing square). The final investment depends on: • Home size and roof complexity (number of planes, dormers, valleys) • Panel metal type (galvanized steel, Galvalume, or aluminum) and thickness • Coating quality and color (standard SMP paint vs. premium PVDF/Kynar) • Removal and disposal of existing roofing • Needed substrate repairs or upgrades (sheathing, ventilation) • Access, steepness, and safety requirements. We provide a free on-site inspection and written estimate so you know the exact cost before work begins.
What does the installation process look like, and how long will my roof replacement take?
1. On-site visit & measurement: We digitally map the roof and order custom-length panels. 2. Tear-off & inspection: Old shingles are removed, decking is inspected, and any damaged wood is replaced. 3. Underlayment & flashing: High-temp synthetic underlayment, ice- and water-shield in critical areas, and new drip edge, valley, and wall flashings are installed. 4. Panel installation: Continuous metal panels are secured with hidden clips and screws, then mechanically or snap-locked together for a watertight seam. 5. Trim & accessories: Ridge caps, snow guards, attic ventilation, and gutter interface pieces are finished. 6. Clean-up & final walkthrough: We magnet-sweep for nails and provide the manufacturer and workmanship warranties. For an average 2,500-sq-ft single-family home, the complete process takes 2–4 days, weather permitting.
