When Your Asphalt Shingles Can’t Keep Up With New Mexico’s High Plains Weather
Last spring, Maria watched as yet another piece of her asphalt shingle roof landed in her Des Moines yard after a particularly fierce windstorm rolled across the high plains. The wind had been howling at 40 mph—nothing unusual for the 88418 area—but her ten-year-old roof was already showing its age. Between the intense UV exposure at our 4,800-foot elevation, the dramatic temperature swings that can drop 40 degrees overnight, and those relentless northeastern New Mexico winds, her asphalt shingles were deteriorating faster than anticipated. She’d reached that frustrating crossroads every homeowner in Des Moines eventually faces: keep patching an aging roof or invest in something more permanent.
Why Metal Roofing Installation Makes Sense in Des Moines, NM
If you’re tired of watching your roof age in dog years while you pay in human dollars, metal roofing deserves serious consideration. Here’s what matters: Des Moines sits in a unique climate zone where we don’t get the snowfall of northern New Mexico, but we do face brutal sun exposure, wind that tests every fastener, occasional hail from summer thunderstorms, and winter ice dams when temperatures hover around freezing. A properly installed metal roof addresses all these challenges while lasting 40-70 years compared to asphalt’s 15-25 year lifespan in our climate.
The standing seam metal roof cost typically ranges from $9-$14 per square foot installed in the Des Moines area, which translates to roughly $18,000-$28,000 for an average 2,000 square foot home. That’s approximately double the cost of asphalt shingle replacement, but when you factor in longevity and energy savings, the math shifts dramatically. Metal roofs reflect solar radiation rather than absorbing it, which can reduce cooling costs by 10-25% during our scorching summers when temperatures regularly hit the mid-90s.
Should You Install Metal Over Your Existing Shingles?
One decision you’ll need to make is whether to pursue metal roof over shingle installation or tear off the existing roof completely. Both approaches have merit depending on your situation. Installing metal over shingles can save $2-$4 per square foot in labor and disposal costs, and it adds an extra layer of insulation. However, this only works if your current roof deck is in solid condition and you have just one layer of existing shingles. In Des Moines’s older homes—particularly those built in the 1960s and 70s near the downtown area—you might discover the roof deck needs repairs or reinforcement to handle metal roofing’s different load distribution.
The tear-off approach, while more expensive upfront, gives your contractor the chance to inspect and repair the decking, improve ventilation, and ensure proper installation of underlayment specifically designed for metal roofing. Given our wind conditions, this inspection opportunity is valuable. I’ve seen too many Des Moines homes where hidden deck damage from years of wind-driven moisture only became apparent after removal.
Critical Questions to Ask Metal Roofing Contractors
When you’re getting quotes for metal roofing installation in the 88418 area, arm yourself with these specific questions:
- What gauge metal do you recommend? For our wind conditions, 26-gauge or thicker steel provides better durability than thinner 29-gauge options, though aluminum (measured differently) also performs well.
- How do you handle thermal expansion? Metal expands and contracts with temperature changes, and Des Moines’s 60+ degree daily swings require proper panel attachment that allows movement.
- What’s your fastener strategy for high-wind areas? Standing seam roofs use concealed fasteners that aren’t exposed to weather—far superior to exposed fastener systems in windy locations.
- Do you include ice and water shield at critical areas? Even with limited snow, ice dams can form along north-facing eaves during our freeze-thaw cycles.
- What’s the paint warranty? Quality finishes like Kynar 500 or Hylar 5000 should carry 30+ year fade warranties—essential given our UV exposure.
- Will you install snow guards? Even our modest snowfalls can create dangerous sliding sheets on metal roofs; metal roof snow guard installation prevents this and protects landscaping and entryways.
Metal Roof vs Asphalt Shingle: The Real Comparison for High Plains Living
Beyond initial cost, consider the total ownership picture. Asphalt shingles require inspection after every significant hail event and typically need replacement every 15-20 years in our intense sun. Metal roofing installation is basically a once-in-a-lifetime expense for most homeowners. Metal also handles our wind better—properly installed standing seam systems are rated for 120+ mph winds, while asphalt shingles start experiencing problems around 60-70 mph, which we see several times yearly in Des Moines.
The maintenance difference is substantial too. While metal roofs rarely need attention beyond occasional inspection, you might eventually want metal roof painting contractors if you decide to change colors or if the finish shows wear after 25-30 years (though quality coatings often outlast this timeframe). Compare that to asphalt’s regular replacement cycle, and the winner becomes clear for long-term homeowners.
Finding the Right Roofing Partner in Des Moines
The key to successful metal roofing installation is finding contractors who understand both the product and our specific climate challenges. Look for installers with specific metal roofing certifications from manufacturers, verifiable local references, and experience with Des Moines, NM’s building requirements and weather patterns. A qualified professional serving the 88418 area should be willing to walk your roof with you, explain their installation process in detail, and provide written warranties covering both materials and workmanship.
