When powerful mountain gusts rip through Duff, HEP keeps homes and businesses protected with craftsmanship that stands up to the challenge. Our crews specialize in high-wind installations, anchoring panels with precision fasteners and reinforcing every seam to prevent uplift, rattles, and leaks. The result is a roof that shrugs off 120-mph gusts, hail, and driving rain while adding modern curb appeal to your property.
Choosing metal roofing means choosing a lifetime of confidence. Cool-roof coatings reflect solar heat for lower energy bills, the interlocking steel or aluminum panels resist fire and corrosion, and HEP backs every project with industry-leading warranties and 24/7 emergency support. From free wind-zone inspections to streamlined insurance claims, we make it easy for Duff residents to upgrade once and never look back—because storm season shouldn’t keep you up at night.
FAQs
How well do metal roofs stand up to the high-wind events we experience in Duff?
Modern steel and aluminum roofing panels are engineered to lock together and are anchored with high-strength screws or concealed clips that penetrate into the roof deck or structural purlins. When properly installed, a metal roof can resist wind uplift pressures of 140–180 mph—or even higher with specialty systems—far exceeding the gusts typically recorded in Duff and meeting or surpassing International Building Code (IBC) requirements for our wind zone.
What specific wind-resistance ratings do your metal roofing systems carry?
Our standing-seam and through-fastened panels are tested under UL 580 (Uplift), UL 1897, and ASTM E1592 protocols. Depending on panel profile and substrate, they achieve Class 90, Class 120, and even Class 180 ratings, translating to design wind speeds of roughly 140–200 mph. We provide stamped engineering packages so you and your building official can verify that the selected panel assembly meets the required wind design pressure for Duff.
Can switching to a metal roof reduce my homeowners insurance premiums for wind damage?
Many insurers consider a properly installed, rated metal roof a ‘fortified’ covering because it is less prone to wind-borne shingle loss and water intrusion. Homeowners in Duff frequently receive discounts of 5–15 percent on the wind or ‘roof surfacing’ portion of their policy. Actual savings vary, so we recommend sending our product data sheet and installation certificate to your carrier after the roof is completed.
What installation practices ensure my metal roof stays secure during strong wind gusts?
1) We fasten panels with stainless or coated screws at manufacturer-specified spacing into solid decking or 1" x 4" purlins. 2) Concealed clip systems allow panels to expand while keeping them locked to the structure. 3) Edge and ridge zones—the areas that experience the highest uplift—receive extra fasteners and continuous cleats. 4) All trims are hemmed and mechanically seamed to prevent wind from getting underneath. 5) Factory-formed sealant gaskets or butyl tape are applied under every lap to stop driven rain.
Do I have to tear off my existing shingles, or can metal be installed over them without compromising wind performance?
A metal-over-shingle retrofit is possible, but for the best wind rating we advise a complete tear-off. Removing the old roof lets us inspect the decking, replace any damaged sheathing, and secure panels directly to a flat, solid surface—eliminating the air gaps that can magnify uplift forces. If budget or disposal concerns favor an overlay, we will install purlin battens and obtain engineering that confirms the assembly still meets local wind design pressures.
What post-storm maintenance should I perform to keep my metal roof wind-ready?
After any major wind event, walk the ground with binoculars or schedule our complimentary inspection. Look for displaced ridge caps, bent trims, or missing fastener heads. Clear branches or debris that may have dented panels or created scratch points where corrosion could start. Every 3–5 years, we tighten exposed fasteners, replace deteriorated washers, and renew sealant in critical seams. Routine checks protect your manufacturer wind warranty—often 30–40 years—and ensure the roof remains a robust shield against Duff’s next high-wind day.
