Galvanized steel roofing sheet

Answers to the Most Commonly Asked Questions
About Metal Roofs

How does the cost of a metal roof cost compare to other roofs?
Metal roofs are a premium product. Although initial costs for a metal roof manufactured from high performance pre-painted steel maybe slightly higher when compared to roofs made from other materials, substantial long-term savings can be realised over a period of time (i.e. life-cycle cost analysis). This is because metal roofs will outlast any asphalt/fiberglass shingle or concrete tile roof. Additionally, metal roofs have many advantages and benefits over asphalt / fiberglass shingle roofs.

Can I walk on a metal roofs?
Yes you can; however, like walking on any roof, you should be careful.

Is a metal roof noisy when it rains?
No, metal roofs are not really all that noisy when it rains. According to one study, the noise levels of a metal roof are about the same as other roofing products such as asphalt or wood shingles or clay tiles.

Can a metal roof be damaged by hail?
Metal roofs are very tough and highly resistant to hail damage... much more so than asphalt/fiberglass shingles. In fact, many metal roofing products have the highest impact resistance and hail rating granted by the insurance commissions in the hail belt regions of the U.S. Some insurance companies even provide a reduced rate for metal roofs.

How about resistance to wind damage?
All metal roofing products are very wind resistant. Many styles have been tested to withstand hurricane force winds; and wind warranties can be as high as 120mph.

Is a metal roof fire safe?
A steel roof is the most fire safe roof. It is classified as a noncombustible roofing material with a Class "A" rating - the highest rating given.

How does the weight of a metal roof compare to other types of roofing?
Much to many peoples surprise, metal roofs are significantly lighter than other types of roofs. Typically they weigh less than one-third the weight of asphalt/fiberglass shingles; and are as much as 75% lighter than clay, concrete or slate.

Will a metal roof rust?
Genuine 55% Aluminum-Zinc coated steel roofing panels are protected by layers of metallic and polymer coatings. Industry studies have repeatedly shown them to outperform the corrosion resistance of other coated metals. They are available from Colourcoil Industries with 25 year warranty* against corrosion.

Does the color fade?
Colour fading affects all painted surfaces when exposed outdoors. The question is when or rather how fast. Commercial Quality (CQ) pre-painted steel, coated with low quality paints will fade very quickly, sometimes in as quick as 3 to 5 years. On the other hand, Colourcoil high performance pre-painted steel are coated with special paints containing high-performance polymers that have exceptional weathering properties. The are available in a wide variety of colours and come with warranties* of up to 20 years against colour fading, chalking and delamination.
