Westman Steel: Benefits of Steel

Pre-painted sheet steel is now the standard roofing and siding product used on agricultural, commercial and residential buildings across North America. Sheet steel is extremely economical, durable, easy to install and readily available. The sheets are normally about 36 inches wide and available in a range of profiles, colours and thicknesses to satisfy both structural and aesthetic considerations. Buildings are going beyond the utilitarian look of the past and incorporating the variety of steel products and colours into very attractive building packages, at an economical cost.


While all Canadian industries re-examine their impact on the environment, the Canadian steel industry is making significant progress in manufacturing greener products for its end users, as well as cleaning up its own manufacturing processes. Steel is the environmental alternative to the current recycling problem in the building industry. The North American steel industry dedicates nearly 15% of its capital spending towards improving the environmental and sustainable development of its facilities.

At approximately 1 lb. per square foot, steel roofing/siding is lighter than asphalt roofing (5 lbs per square foot), which means less stress on the building, allowing for better architectural designs.

Weather Resistant

Fire Resistant

Steel roofing and siding doesn’t shrink, crack, split, curl or rot. It has been tested to resist acid rain, winds up to 110 mph, hail damage, high temperatures, sun exposure, and other weather conditions. Best of all, it retains its color and shape better than other roofing/siding materials. Westman Steel offers a 40 year warranty giving you the peace of mind that your project will stand the test of time.


Steel roofing/siding is available in a variety of styles and colors to suit any design or architectural flare. It can also replicate the look of wood, copper, stone or clay roofing without encountering decay problems.

High Quality

All WESTMAN STEEL roofing is made from Galvalumeâ„¢ aluminum-zinc substrate or galvanized steel and conforms to Canadian Sheet Steel Building Institute (CSSBI) standards to ensure the best quality possible.

Reduced Heat and Sound

Steel roofing transfers heat away from the interior, unlike asphalt shingles which retain heat. With proper insulation and ventilation, buildings stay cooler in summer and warmer in winter, saving money on heating and cooling costs.

Reduced Disposal Costs

Replacing your roof can be expensive and a big hassle. The disposal costs of your old shingles alone can be as much as 10-15% of the cost of a new roof. Studies continue to prove that metal roofing/cladding has the best return on investment. This means the one-time investment in metal roofing or siding is more cost-efficient than re-doing your roof or siding 2-3 times during the same time period with regular materials (asphalt shingles, etc).

Built to Last

Steel roofing lasts 2 to 3 times longer than traditional roofing, which means 40 to 60 years! All WESTMAN roofing comes with a 40 year limited transferable warranty, but with proper care should last much longer.
