Features & Benefits

Standing seam metal roofing systems are suitable for commercial, institutional, and residential applications for buildings both large and small. They are adaptable to both low- and steep-slope designs and offer a wide range of size and finish options. In addition to offering exceptional value and longevity for building owners and occupants, metal roofing is a safe and environmentally-conscious alternative to other roofing materials.

Cost Effective

Although the initial cost of metal roof systems may be higher than shingles, the cost/benefit ratio over the life of the roof is superior to that of a shingle system and far superior to either shake, slate or tiles. Metal roofing systems manufactured to exact length also contribute to a fast and installer-friendly application process, keeping labour costs reasonable and construction project duration shorter.

Light-Weight

Metal roofing can be as little as 1/10th the weight of competing roof materials, translating to lower transportation and construction costs.

Aesthetics

Metal roofing is beautiful as well as durable and is available in many different styles, configurations, and colors to fit diverse architectural requirements and tastes. Local building codes and design/performance requirements should be reviewed when considering standing seam roofing.

Life Expectancy

A quality metal roof that is properly installed could last the lifetime of the owner. In fact, because metal withstands so many elements, metal roofing is known for its extensive life cycle.

Weather Resistant

Properly installed metal roofing systems will withstand inclement weather (high winds, hail, snow and rain) better than any other roofing material. With proper installation, metal roofing is just as lightning-resistant as other roofing material.

Durability

Metal roofing is a much better overall investment – it is longer lasting, durable and more weather-resistant (no warping, cracking, or peeling) and it does not burn and is impervious to termites and pests. In testing, metal systems have withstood winds up to 200 m.p.h. and have historically survived hurricanes and wind storms when other materials have failed.

Application

Standing seam metal roofing systems are suitable for new construction or renovation projects with slopes as shallow as ¾/12 pitch*. It is especially cost-effective in re-roofing applications where it can be installed over the existing roofing material, bringing significant savings in time and labor in addition to eliminating the problem of disposal.

*Especially low-slope roofing may require additional weatherproofing or membrane products to meet performance requirements. Consult building code and/or National Roofing Contractors’ Association guide to properly select all system components.
