Dent Resistance
Dent Resistance | Metal Roofing | Roofing | Palmer
When Palmer’s winds howl and hailstones hammer down, HEP’s dent-resistant metal roofing stands guard over your home. Forged from high-gauge steel and finished with a specialized impact-deflecting coating, each panel shrugs off flying debris, tree limbs, and toys gone rogue, all while delivering a sleek, contemporary look that lifts curb appeal. Because it’s engineered for Alaska’s freeze-thaw cycles, you get year-round protection without the rattles, leaks, or rust that plague ordinary roofs.
Homeowners also love the smart extras built into every installation:
• Hidden fastening systems that lock out moisture and 120 mph winds
• High-density insulation to keep winter heat in and summer sun out, trimming energy bills
• A transferable lifetime warranty that boosts resale value as reliably as the roof boosts security
From first inspection to final shingle, HEP handles everything with local know-how and neighborly care, so you can relax under a roof that’s as tough as Palmer itself—and looks great doing it.
FAQs
What makes your dent-resistant metal roofing different from standard metal panels?
Our dent-resistant panels are manufactured from 24-gauge, high-tensile-strength steel that is nearly 30 % harder than conventional 29-gauge roofing. The added thickness and tensile strength disperse impact energy from hail, falling branches, or errant baseballs, so the surface springs back instead of dimpling. In addition, we use deeper ribbing and a concealed-fastener design, both of which increase structural rigidity and resistance to deformation.
How well does the roof stand up to Palmer’s frequent hail and wind-blown debris?
Lab tests performed to UL 2218 Class 4 standards show our panels can withstand 2-inch steel balls dropped from 20 ft without cracking or denting, which is equivalent to golf-ball-sized hail. In real-world field tests around Palmer, roofs have endured 60-mph wind-blown pea-size gravel and tree litter with no visible damage. The tougher steel and baked-on PVDF coating prevent divots, while tight interlocking seams keep wind from flexing the panels.
Will the paint finish crack if a large object hits the roof?
No. The PVDF (Kynar 500®) finish we apply is formulated to stay flexible enough to move with the metal substrate. Even when an unusually heavy impact does leave a slight cosmetic mark, the paint bonds at a molecular level and resists cracking, chalking, or peeling. This protects the underlying steel from moisture, preventing rust and extending the life of the roof well beyond its 40- to 50-year warranty period.
Does Palmer’s freeze-thaw cycle affect the roof’s dent resistance over time?
The high-tensile steel’s low thermal-expansion coefficient means it expands and contracts far less than aluminum or thinner steel panels. Because micro-movement is minimal, stress fatigue around fasteners and seams is virtually eliminated. That stability, combined with a weathertight clip system that floats on the deck, preserves the panel’s structural integrity through decades of Palmer’s freeze-thaw cycles without increasing its susceptibility to denting.
Can a dent-resistant metal roof be installed over my existing asphalt shingles?
In most cases, yes. As long as your current deck is sound and local code permits, we can install a vented underlayment and then attach the new impact-resistant panels over the shingles. This saves tear-off costs, adds an extra moisture barrier, and enhances energy efficiency. An on-site inspection will confirm whether your structure can handle the additional 1.5 lb/ft² weight of the steel panels.
Is dent-resistant metal roofing more expensive, and does it pay off?
Upgraded 24-gauge dent-resistant panels cost roughly 10-15 % more than standard 29-gauge panels, but they can save money long-term by preventing hail damage claims, repainting, or premature replacement. Most homeowners in the Palmer area recoup the difference within 7–10 years through lower maintenance bills and potential insurance premium discounts for UL 2218 Class 4 roofs.
