METAL ROOFING BY CMG

METAL ROOFING IS ONE OF THE MOST DURABLE, LOW-MAINTENANCE ROOF SYSTEMS AVAILABLE. WE INSTALL CMG PRODUCTS FOR LONG LAST PERFORMANCE, CLEAN LINES, AND RELIABLE PROTECTION.

WHY METAL ROOFING IS A GREAT CHOICE

METAL ROOFING IS A HIGH-PERFORMANCE ROOFING SYSTEM BUILT FOR LONGEVITY, TOUGH WEATHER, AND A CLEAN DESIGN. IT'S A SMART OPTION FOR HOMEOWNERS WHO WANT A ROOF THAT CAN HANDLE HARSH CONDITIONS, REQUIRE LESS MAINTENANCE OVER TIME, AND STILL LOOK SHARP FOR DECADES.

BUILT FOR EXTREME WEATHER

PERFORMS WELL IN WIND, HEAVY SNOW LOADS, AND FAST TEMPERATURE SWINGS.

LONG LASTING VALUE

METAL ROOFS ARE KNOWN FOR LONG SERVICE LIFE, MAKING THEM A STRONG LONG-TERM INVESTMENT.

LOW MAINTENANCE

DOESN'T CRACK OR CURL LIKE SOME MATERIALS AND TYPICALLY REQUIRES LESS ONGOING UPKEEP. DEPENDING ON WHICH PROFILE YOU CHOOSE, OIL CANNING STILL CAN OCCUR.

SHEDS SNOW EFFICIENTLY

SMOOTH PANEL SURFACES HELP SNOW SLIDE OFF MORE EASILY ESPECIALLY WHEN PAIRED WITH PROPER SNOW RETENTION SYSTEMS.

FIRE-SMART OPTION

METAL IS NON-COMBUSTABLE AND ARE MADE FROM FIRE-RESISTANT METALS LIKE STEEL, ALUMINUM AND COPPER. THE PANELS INTERLOCK TIGHTLY, MINIMIZING GAPS FOR EMBERS TO FLY IN. 

PROTECTIVE COATING SYSTEM

CMG OFFERS DURABLE COATINGS THAT PROVIDE LONG-LASTING PROTECTION AND VIBRANT COLORS. OPTIONS LIKE ULTRA-CLAD HYLAR AND ULTRA LOW GLOSS PVDF ARE EXTRA ADD ONS FOR PRESTINE FINISHES AND RESISTANCE AGAINST FADING.

ENERGY-CONSCIOUS FINISHES

METAL ROOFS REFLECT SOLAR HEAT, REDUCING COOLING COSTS IN THE SUMMER.

BOX RIBS

DETAILS

  • Two raised "box" ribs that create a more structured, architectural look.
  • Uses concealed attachment methods with the rib shape built into the panel for stiffness.
  • Adds visual depth and can help panels feel more rigid than a totally flat look.
  • The added shape helps reduce how noticeable oil canning can look compared to smooth, flat panels.
  • Panels are offered in all CMG standard finishes as well as Bonderized, A606, and Galvalume Plus.

CORRUGATED PANELS

DETAILS

  • A classic panel with repeating rounded or wavy ribs.
  • Installed by an exposed-fastener system with overlapping laps.
  • Gives a timeless rugged look thats typically more budget-friendly.
  • Great for cabins, barns, shops, and accent roofs.
  • Panels are offered in all CMG standard finishes as well as Bonderized, A606, and Galvalume Plus.

SNAP-LOCK PANELS

DETAILS

  • Snap Lock panels have a male/female seam.
  • Installers attach the panel to the roof deck with clips or concealed fasteners, then the next panel snaps over the seam to lock it in.
  • Faster installation than mechanical-lock seams.
  • Clean appearance and hidden fasteners.
  • Great for most residential steep-slope roofs - recommended 3:12 pitch or greater.

spec sheet

SINGLE- LOCK MECHANICAL PANELS

DETAILS

  • This is a mechanically seamed standing seam where the vertical seam is folded/locked once.
  • Panels are set with sealed clips/fasteners, then the seam is crimped to lock the adjacent panel.
  • A strong clean look with the added security of a true seamed connection - more "locked in" then snap systems.
  • Great for tough weather, often selected when you want a mechanically seamed roof but don't necessarily need the tightest seam.

spec sheet

DOUBLE-LOCK MECHANICAL PANELS

DETAILS

  • Mechanically seamed where the seam is folded/locked twice for extra-secure seam closure.
  • Same concealed- clip setup, but the seam is double-folded for a tighter lock and higher seam integrity.
  • Maximum seam security - commonly chosen for higher exposer, harsher conditions, or low-slope application where extra strength is needed.
  • The most resistant to wind-driven weather and movement.
  • Best for those who want the highest level of mechanical seam closure and long-term durability.

spec sheet

FLUSH PANELS

DETAILS

  • A standing seam panel style with a flat, smooth face - no ribs or texture across the panel field.
  • Panels attach with concealed clips, then seams lock together.
  • The most clean, modern, high-end look - simple lines and a sleek finish.
  • Because the panel face is flat, oil canning can be more noticeable.

GAUGES

22 Gauge (Thickest / Most Rigid)

 Our heaviest-duty option. 22 ga is the most rigid and typically offers the best resistance to “oil canning” and minor denting. It’s a great fit for premium builds or homeowners who want maximum strength and longevity. 

24 Gauge (Standard / Best All - Around)

 A popular, balanced choice for residential metal roofing. 24 ga offers strong performance and durability while keeping cost and weight in a practical range. This is often the “go-to” gauge for many standing seam projects. 

26 Gauge (Thinnest / Most Economical)

 Our lightest and most cost-effective option. 26 ga is commonly used for Delta Rib / exposed-fastener panels, especially on garages, shops, and outbuildings, or projects where budget is a bigger driver while still wanting the benefits of a metal roof.
