Curved Metal Roofing

Curves are in! Whether simply used as a design accent or for an entire roof, radius roofing is gaining in popularity. McElroy Metal offers five distinct standing seam systems that can be curved right on the jobsite which both lowers transportation cost and ensures a proper fit.  These standing seam systems include Maxima 1.5, Maxima ADV, 138T, 238T, and Medallion I.

Medallion I curving is performed on the jobsite by roofing contractors using rented curving equipment. Curving equipment is available for rent through Developmental Industries at mcelroyseamers.com, a website created just for McElroy customers. DI is the only approved supplier for this type of equipment.  Maxima 1.5, Maxima ADV, 138T, and 238T panels are curved on the jobsite by McElroy Metal roll forming technicians.  Contact your McElroy representative for pricing and details.

FAQs

Metal roofing consistently outperforms shingles when it comes to resisting harsh elements. In addition to being fire and hail resistant, metal roofs are also effective against extreme winds. Many insurance companies recognize the durability of metal roofing, offering discounts for structures with metal roofs.

Thanks to a combination of ASV (Above Sheathing Ventilation) and special coating designed to reflect the sun’s energy and release absorbed heat, metal roof panels can reduce energy costs by as much as 20% compared to asphalt shingles.

Compared to shingles and clay tile, metal roofing holds up better against hail and extreme winds in addition to being fire resistant. In fact, many insurance companies offer discounted rates to homes with metal roofs because they’re more likely to hold up under harsh conditions.

With a lifespan of up to 60 years, a metal roof is an ideal long-term solution for residential roofing. Homeowners can rest easy knowing that they won’t need to replace the roof before selling their house or shortly after purchasing a new home.

While it may be true that metal roofs on buildings like garages and pole barns intensify the sound of falling rain, this is primarily caused by the lack of a roof deck, insulation, and underlayment. On a residential home, layers of building materials between the metal roof and the living area reduce the noise significantly, making metal roofs as quiet as any other roofing material when it rains. Check out this video to see and hear for yourself.

Metal roofing actually reflects much of the sun’s heat and energy. While conventional shingles absorb much of the sun’s heat, metal roofing can actually reduce cooling energy costs by as much as 20%. That’s because the coating used on modern metal roof panels incorporates special pigments that reflect the sun’s energy and release heat that is absorbed throughout the day.

The odds of a lightning strike hitting a metal roof are the same as any other roof, regardless of material. In the event that there is a lightning strike, however, metal roofing will not ignite and catch fire since it is not combustible.

Far from it. Studies conducted by the Insurance Institute for Business & Home Safety (IBHS) have found that metal roofing is far less likely to be punctured by hail than conventional asphalt shingles, withstanding even golf ball-sized hailstones with only cosmetic damage.

Metal roofing consistently outperforms shingles when it comes to resisting harsh elements. In addition to being fire and hail resistant, metal roofs are also effective against extreme winds. Many insurance companies recognize the durability of metal roofing, offering discounts for structures with metal roofs.
