AGAWAM, Mass. — When it comes to protecting commercial roofing systems in extreme weather, the edge metal system is roof’s first line of defense. As such, OMG’s line of TerminEdge Fascia and PermaSnap Coping systems are ideal for use on hospitals, schools or other buildings that are often designated as ‘shelters’ during severe weather events, according to the company.

TerminEdge is one of the industry’s strongest facia systems with Factory Mutual (FM) system ratings up to 1-315. The system is ANSI/SPRI/FM-4435/ES-1 tested, FM approved, compatible with most commercial roofing systems, and available in a range of sizes from 3.75-in. to 13-inches to accommodate most building needs.

The three-piece fascia system consists of a continuous formed galvanized or extruded aluminum retainer (depending on the rating) that is self-locating and pre-punched with slotted holes to accommodate building expansion and contraction. The snap-on fascia cover is available in 24- or 22-ga. galvanized steel, or in .040-, .050- or .063-in. aluminum (again, depending on the required rating). Matching 4-inch wide concealed splice plates allow fascia covers to expand and contract without creating visible gaps.

PermaSnap is an FM tested and approved coping system for use on parapet walls up to 32-inches wide, and offers some of the highest wind ratings in the industry. PermaSnap is compatible with most roofing systems and is available with face heights of 4- to 12-inches.

The highest performing PermaSnap system comes with heavy duty 16-ga. galvanized steel clips, six-inch wide concealed splices with integral gutter and snap-on coping cover. A dual hook cover profile provides a clean professional look and offers some of the highest wind protection ratings in the industry: up to an FM 1-120 system rating for walls up to 28-inches wide.  Snap on covers are available in 24- or 22-ga. galvanized steel or .040-, .050-, .063 or .080-in. aluminum.

“We’ve seen an increase in the frequency and severity of storms across the U.S. in the past few years. With these changing weather patterns, it’s important that design professionals carefully evaluate the roof’s edge system whenever specifying a roof for a hospital, school or any building designated as a shelter during a major storm,” said Patrick O’Connor, product manager for OMG EdgeSystems. “We have a long and successful history of supplying high performance edge systems for these types of facilities.”

Both TerminEdge and PermaSnap edge metal systems are available with a 25-year Category 5 wind warranty for wind-speeds up to 155 mph.  All OMG EdgeSystems products are supplied in 10-foot lengths for easy handling on the roof. In addition, users have a choice of 31 standard colors to match virtually any design requirements.
