FAQs
Why is metal roofing a good choice for homes in Kelso and the wider Pacific Northwest climate?
The Pacific Northwest is known for its persistent rain, periodic snow, high winds, and seasonal temperature swings. Metal roofing excels in these conditions because it is non-porous, sheds water quickly, resists moss and algae growth, and carries wind ratings of 120–140 mph when properly fastened. In addition, the coated steel, aluminum, or zinc alloys used today are corrosion-resistant, so they will not rust despite the area’s constant moisture. Homeowners gain a roof that can last 50+ years, far exceeding the 15–25-year life span of typical asphalt shingles.
How does a metal roof handle Kelso’s heavy rainfall and potential moss growth?
Metal panels have a smooth, hard surface that allows rainwater to run off almost instantly, which minimizes standing water and prevents leaks. Because the surface does not retain moisture and has no granular surface for spores to cling to, moss and algae have difficulty taking hold. Many products also have factory-applied PVDF or SMP finishes with built-in mildew inhibitors, adding another layer of protection. In most cases, an annual rinse with a garden hose is all that’s needed to keep the roof clean.
Will a metal roof protect my home from the high winds and occasional snow or ice storms common to Cowlitz County?
Yes. Standing-seam and screw-fastened metal roofing systems are engineered to interlock tightly and are tested to withstand winds well above the strongest gusts typically recorded in the Kelso-Longview area. The panels’ slick surface also encourages snow to slide off before heavy loads develop, reducing the risk of structural stress and ice damming. For regions that experience ice storms, optional snow guards can be installed to control the slide and keep snow from dumping all at once near entryways.
Is metal roofing energy-efficient in the Pacific Northwest’s mild summers and cool, damp winters?
Modern metal roofing is often ENERGY STAR® listed. The reflective coatings bounce a portion of the sun’s infrared rays, helping keep attic temperatures lower during sunny summer afternoons. In winter, metal’s low thermal mass means it releases heat quickly at night, reducing the chance of snow melt and refreeze at the eaves (ice dams). Pairing the roof with a continuous ridge vent and proper attic insulation further improves year-round efficiency, potentially lowering heating and cooling bills by 10–25 % compared to a dark asphalt roof.
How long can I expect a metal roof to last in Kelso, and what maintenance does it require?
A quality 24- or 26-gauge steel, aluminum, or zinc roof typically lasts 40–70 years in the Pacific Northwest, depending on the profile and coating. Warranties of 30–50 years on paint and weather-tightness are common. Maintenance is minimal: keep gutters clear, remove large branches or debris after windstorms, and have fasteners or sealant points inspected every 10 –15 years. Unlike cedar shakes or asphalt shingles, metal roofs never need periodic chemical treatments or re-roofing layers.
Does installing a metal roof raise any noise concerns during the region’s frequent rainstorms?
When installed over solid decking (plywood or OSB) with an underlayment—as required by Washington State building codes—a metal roof is not significantly louder than an asphalt roof. The sheathing, insulation, and attic air space all act as sound dampers. Most homeowners report only a soft, muted patter during heavy rain, and many find it pleasant. If additional sound reduction is desired, high-density foam backer boards or acoustic underlayments can be added during installation at a modest extra cost.
