The greatest structural burden on the house comes from the roof. A heavy roof will cause the house to shift and settle, causing cracks and structural misalignment. These effects may be evident as early as three to five years after installation. All national building codes dictate that if the weight of the roofing material exceeds six pounds per square foot then the residence will require additional structural support. This will often incur additional expenses for structural analysis, materials, and installation. Additionally, older homes that require re-roofing are often in need of structural reinforcement when using concrete, clay tile, or fiber-cement.

Weighing at average of 1.4 pounds per square foot, a Roser roof is an ideal solution for homes or commercial projects that cannot be structurally altered, or when structural changes would incur significant costs. A Roser Stone Coated Steel Roof was not only designed to decrease structural load on a residence.  It also improves the structural integrity of the house through an interlocking fastener system, providing significant reinforcement during physical stresses such as hurricanes, earthquakes, and hail storms.

Homeowners and installers often choose Roser for applications for where they want the look of tile or shake, but cannot go with concrete or cement due to weight restrictions.  Additionally, Roser Tile, Shake and Shingle profiles are offered in a greater variety of colors then concrete, cement or asphalt roofs.

The interlocking profile is an excellent protection from debris, which is known to break and tear up cement and asphalt shingles.  The Roser panel, with its steel core, maintains its structure upon impact of 2.5″ hailstones, thus making it a premier performer in the industry.   The Stone Coated Steel Roof system is highly recommended in every part of the country that has a high hurricane potential.

The Roser 26 gauge steel roofing system is an unparalleled solution in areas susceptible to hail storms. The industrial grade warranty coverage extends to 2.5’ inch hailstones, making it ideal for homeowners. Hailstones are known to cause thousands of dollars worth in damage to roofing structures, requiring extensive repair and in some cases complete re-roofing. Clay, concrete tiles, fiber cement, composition shingles, and cedar shakes will often crack, shatter, and displace during hail storms. In some cases, debris can pose a danger to occupants.

In 1996, Underwriters Laboratories developed Test Standard UL 2218 to gauge the hail resistance of roofs on a four point scale. Steel balls are dropped from different heights on the roofing material to test the resistance of the roof and simulate a hailstorm. If the roofing material is given a rating of one, then it’s the most susceptible to damage during a hailstorm. A rating of 4 indicates that it’s the best the roofing material available to residential and commercial projects.

As an example, a standard wood shake roof receives a Class 1 UL rating while a typical asphalt shingle roof will receive a rating of 2 or 3. The Roser Roofing System is given a Class 4 rating which is the highest in the industry. The interconnected panel system dissipates impact across the roofing structure, minimizing damage potential. The 26 gauge steel is among the toughest roofing materials available.

Class 4 rated products are qualified for home insurance premium reductions because they increase safety characteristics of the house. Some homeowners reported that they saved as much as a thousand dollars in their annual premiums. Houses in hailstorm areas typically require re roofing as often as 15 years when protected by standard shake or shingles.  A Roser Roof, engineered for impact resistance, is backed by a 50 year warranty which includes hail damage.

An earthquake can cause a roof to shift and dislodge its heavy shake and tile shingles. This can create a danger of falling debris. When an earthquake shakes the frame of the house and the roofing materials are heavy enough, then some of the framing parts can dislodge, causing a partial or total roof collapse. Many houses, after going through an earthquake have been left flattened or partially destroyed because heavy roofs have caused too much stress on the structure.  

During an earthquake, the Roser Roofing System exhibits the best performance when compared to other roofing materials. Weighing in at only 1.4 pounds per square foot, Roser places minimal stress on the house frame.  Additionally, the interlocking panel system reinforces the house structure.
