Why “metal roof” and why CLM Steel Roofing?

Driving through the residential neighbourhoods you might have noticed more and more people are opting out for a metal roof. You might ask yourself “Why go for metal roof if you can re-shingle the roof at a lower price?” The truth is shingles have lost their longevity and endurance due to a ban on asbestos in 1989. Asbestos was a crucial component in shingles as it has great textile strength and provides great resistance to chemical damage and weathering. After asbestos was discovered to have direct link to cancer Canadian government has outlawed the use of asbestos, and, as a result, the life expectancy of an installed asphalt shingle roof is 10-15 years. In addition to low life expectancy there are other reasons why asphalt shingles are inferior to a Toronto metal roof:


Shingles have trouble withstanding harsh Canadian weather, as a result constant maintenance and repair is needed which actually increases the life cycle cost of Toronto steel roofing drastically

Steel roofing products offered by CLM Toronto metal roofing are manufactured to withstand RC3 levels of corrosion (such levels of corrosion are present in industrial and marine environments). With RUV4 level of ultraviolet resistance, our products can tolerate UV rays at altitudes of up to 2,100 meters above sea level, which results in minimal discoloration.

Save on your energy bill!

During the summer months you might have noticed that it gets very hot in the attic without metal roofing. This is due to the fact that shingles soak up the heat from the sun, and due to poor ventilation that heat is trapped in the attic and transferred to the rest of the house. This of course increases your energy consumption

Unlike asphalt shingles, metal roof is not installed directly over your roof/shingles. The space between the metal and your roof provides airflow and ventilation throughout the roof. In addition to that, metal roof reflects 85% of sunlight which means that your attic will not trap heat and your energy costs can be decreased by as much as 30% (depending on the property layout).

Help planet Earth!

Only about 5% of your shingle roof is recyclable. This means that about 95% of asphalt shingles end up in our landfills which will take thousands of year to decompose.

Voestapine metal roofing material is 100% recyclable – this will decrease your environmental footprint and give you peace of mind knowing that you are contributing to reducing the amount of harmful waste in our landfills. CLM steel roofing in Toronto products are manufactured in Austria by steel manufacturer Voestalpine – one of the largest steel manufacturers in the world, and a pioneer when it comes to environmentally sustainable steel manufacturing. Since 1998, Voestalpine completely removed chromium and chromate from the paint which is used to cover the metal tiles and opted for 100% organic substitutes. This actually increased the durability of metal roofing and made it even more environmentally compatible.

Read the fine print when it comes to warranty

Asphalt shingle manufacturers offer warranties of up to 50 years. However, in the fine print you will discover that only the first 3-5 years are completely covered by the warranty. After the initial period the pro-rated warranty takes over, which means that, depending on when the roof was installed and the thickness of the shingles, you may only be eligible for as little as 10% of the value of the product.
