METAL ROOFING FAQ

Most frequently asked questions and answers

Metal Roofing fulfills the building owner’s need for durable, puncture-resistant protection against the weather while working in concert with the forces of nature.

Metal roofing has an established track record in new construction, where it has been used in some 50% of all low-rise commercial and industrial buildings erected in the last several years.

Yes. Fiberglass blankets are the most common insulation material in standing seam metal re-roofing projects. 

On some projects, un-faced fiberglass insulation is simply laid directly on the existing roof surface before insulation blankets of the new standing seam roof. For other projects, insulation blankets are installed directly under the metal panels and stretched over supporting members. Foam insulation blocks are often used to separate the panels from the purlins to prevent thermal short-circuiting and condensation from forming. The roof expands and contracts independent of the insulation, giving the roof surface a floating action.

Standing steam metal roofs pay for themselves from the day that they are installed. Moreover, they are cost-competitive.

Twenty-year material warranties are customary for metal roofing systems, which is considerably longer than the standard protection for built-up and single-ply systems. 

High wind-uplift ratings can also substantially reduce insurance rates high-wind areas.

Standing seam metal roofs assure adequate drainage from rain and snow, effectively solving ponded water problems, leaks and other related troubles commonly associated with flat built-up roofs. 

The panel fastening system is uniquely designed to handle potentially damaging effects from thermal movement. Precisely formed, factory-made metal panels are locked in place by clips inside a raised seam standing two to three inches above the roof surface. The clips have a moveable feature that allows panels to expand and contract with temperature changes. The concealed clip system reduces the chances of leaks and makes the standing seam roof attractive.

Metal roof panels resist corrosion with the help of a zinc, aluminum, or aluminum-zinc alloy metallic coating applied to the base steel.

Additional protection can come from attractive, specially pigmented organic paints that harmonize the roof with conventional brick, concrete and wood sidewall materials. Popular beige and earth-tone colors allow architects to coordinate the roof attractively with other design elements of the building.

 

The standing seam metal roof is designed to withstand rain, wind and snow, and still remain weather tight. Panels are joined together by a weather tight seam that is raised above the roof’s drainage plane. 

Metal panels are attached to the roof substructure with concealed clips. These are roll formed or crimped into the panel seams without penetrating the corrosion-resistant steel weathering membrane. The clip system performs two functions: It retains the panels in position without exposed fasteners, and allows the roof to expand and contract during temperature changes.

Standing seam metal roofs are also designed to perform in high-wind conditions and can qualify for the Ul-90 wind-uplift rating. This is the highest rating in the industry. 

Yes. Steep slopes and flat roof profiles can be designed with the standing seam roof. The structural roof is the industry’s alternative to flat build-up and single-ply systems.

The architectural standing seam roof is used for visually exposed roofs, mansards facia, and similar applications.

Like wood shakes, tile and slate, this application needs some form of decking for support and a base felt for added protection against moisture penetration.

 

Unlike flat built-up roofs that require frequent maintenance, standing seam metal roofs offer 20 years and beyond of trouble-free performance with little or no maintenance time or expense.

The overall recycling rate of steel products in North America is 70.7%, the highest of any construction material. 

Building professionals are becoming increasingly aware of the importance of using recyclable metal roofing materials for retrofit applications over old non-metallic roofs. This helps avoid expensive tear-off and disposal of solvent and chemical-based materials, which often wind up in overburdened landfills.

Metal roofs can be installed year-round. Heavy rain, extremely cold weather or high winds are about the only conditions that prevent metal roof installers from working. In most projects, the metal roof can be installed right over the existing roof, eliminating costly and time-consuming tear-offs. Owners do not need to close the building area being re-roofed if the work must be done while occupants are inside. Occupants can continue their normal activities, even in the immediate area being re-roofed.

In most retrofit projects, standing seam roofs can be installed right over existing built-up roofs, eliminating costly and time-consuming tear-offs. The metal panels are attached to a steel sub-assembly to provide the necessary slope for ice and water to drain, providing a low-slope solution to flat built-up roofs.

The standing seam roof handles thermal shock through its concealed, sliding clip system. The clip assembly uses a rigid base attached to the building’s structural members. An upper part clips the roof panel and forms into a seam during the seaming operation. The clip allows equal amounts of movement in either direction.

Metal roof panels weigh a relatively modest 1-1/2 pounds per square foot.
