In past decades steel roofing was considered mundane and utilitarian, suited only for outbuildings and commercial warehousing . Modern steel shingles are an attractive product, fabricated, shaped, and painted with ultra-durable coatings and finishes. Steel can offer the appearance of high end roofing products like slate, copper, tiles, asphalt, or even cedar shakes. For the discriminating homeowner seeking a long-term roofing solution, a quality steel shingle offers superior durability, and modern designer elegance with a variety of styles and many colours to choose from.
Why Choose Steel Roofing Shingles?
Although heavier than aluminum, metal shingles made of steel, at an amazingly low weight of about one pound per square foot, are far lighter than common asphalt products which weigh about 5 lbs per square foot, and steel is much stronger. Offering longer life and better performance, steel is hard to ignore.
Why are Steel Shingles a Better Choice?
Steel shingles may be placed over old roofing and reduce waste disposal costs. Steel transfers heat and reduces cooling costs, but also reflects much of the heat from the sun. With a Class A fire rating, high wind resistance up to 120mph and the capability to resist serious hail damage, steel can reduce insurance costs. Metal does not catch fire or support combustion, and shingles made of steel do not break, crack, curl, rot, or blister with exposure to the sun. Insect damage is non-existent. Steel is a logical choice.
Steel Roof Durability
Modern steel roofing shingles are highly durable and long-lasting. Galvanizing, Galvalume and other treatments allow steel to resist rust for many years. Pre-treated steel is finished with tough, resilient finishes that allow manufacturers to offer even transferable, non-pro-rated warranties of a lifetime.
Installation procedures vary with the design, but most applications are similar to other shingles. Installation is completed with galvanized roofing nails or screws any roofing deck that is even and solid. Some steel products are interlocking designs, and installation instructions provided by the manufacturer for these products must be carefully followed. Steel shingles may be installed on spaced sheeting or over existing roofing products.
Ideal Applications for Steel Roofing Shingles
For heritage replacement roofing, commercial, church, or new residential installations and whether in extreme weather geographical conditions or not, stone-coated steel roofing shingles will provide a durable and reliable long-life roofing solution.
Rating of Steel Roofing Shingles
With a Class A fire rating, non-combustible steel has earned the highest possible rating.
With some products offering even a Class 4 listing UL 2218 rating against 2-1/2″ Hailstones, steel shingles offer better than average resistance to hail damage.
Wind resistance increases substantially if interlocking shingle designs are chosen, but wind resistance up to 120mph is common for shingles made of steel.
Steel products cost more than typical asphalt shingles do, however, the installation of a quality stone-coated steel shingle roof is considered to be a cost-effective one-time roofing solution. Asphalt has to be replaced every 20-30 years, where steel is permanent.
The weight of a steel shingle roof is about 1 lb. per square foot, far less than half of the lightest asphalt roofing. Less stress is placed upon trusses and other structural components.
The potential long life of stone-coated steel shingles is reflected in the transferable, non-prorated warranties offered by manufacturers. A quality steel roof can last a lifetime.
Modern finishes and stone coatings applied to formed steel shingles can duplicate any appearance desired including upscale slate, cedar, dimensioned asphalt, or tile roofing. With colours and designs highly varied, the consumer is offered many choices and excellent curb appeal.
Recycle that Roof
An excellent choice environmentally, steel shingles can be made of recycled steel, and the shingles can be recycled if removed. Use of steel also allows installation over older asphalt roofing, which eliminates the necessity of tear-off and dumping of old shingles.
One of the better choices for roofing, steel shingles offer a lifetime roofing solution.
