Installing Metal Roofing -- What You Need To Know

Installing Metal Roofing

So, you're thinking about installing some metal roofing? Very good -- you made a good choice, but there are some things you need to think about first -- and that's the subject of this article.

First of all, were you aware of the fact that installing metal roofing has advantages over other types of roofing materials? One of the greatest advantages of a metal roof is that is lightweight -- pound for pound, metal roofing is one of the strongest, and lightest, of all roofing materials. After all, why do you think that folks are busy installing metal roofing instead of other types in many third world countries?

Another reason to install metal roofing is that it is not only lightweight but very strong and durable. In fact, metal roofing being manufactured today is often made with special coatings that enhance its strength and durability, far more so than metal roofing products manufactured just a few short decades ago.

Another great reason why you should install metal roofing -- particularly if you live in a hot region of the country -- is that you can purchase metal roofing with specially-applied coatings that will reflect light and heat. An additional reason why many homeowners install metal roofing is that, unlike asphalt shingles or wood, metal roofing is not (at least directly) combustible.

When you are installing your metal roofing, if you will be installing a large-sized room, you should make note of the fact that in hot weather, the metal roofing may expand -- and your roof construction must allow for this expansion. In addition, if you will be installing your metal roofing on a curved roof surface, this expansion/contraction may actually produce a noise.

Another thing to be careful of when installing metal roofing, is to make sure that you do not use different types of metal products that are very different from each other. That is because these incompatible metal roofing materials can cause your metal roof to begin to deteriorate very quickly.

Now, when installing your own metal roofing, you should be aware of the types of metal roofing products in existence. The old "granddaddy" of metal roof materials was corrugated galvanized iron. This was simply a plate of wrought iron which was coated with zinc -- however you really won't find this being manufactured any longer.

You may however, find galvanized steel being used as a metal roofing product. While galvanized steel is available, is not really used very much anymore when installing metal roofing -- but you may still see it advertised from time to time.

Another type of metal roofing product you will find is one made from steel coated with a combination of zinc, aluminum, and silicon. Please be aware when installing metal roofing not to mix galvanized steel with steel which has been coated with aluminum/zinc. They are not compatible, and could cause premature degradation of your metal roof.

Some other metal roofing products include stainless steel, aluminum (installed metal aluminum roofing can be quite expensive, but very durable), copper and other materials. Some specialty metal roofing materials are designed for long life even in the harshest weather conditions.

After installing your metal roofing, from time to time your roof will need a certain amount of maintenance. In addition to a periodic inspection to repair/replace any worn spots, loose nails, etc., your metal roofing will need to be re-coated -- once the original finish has worn off, if your metal roofing is not re-coated it can become corroded and worn-through very quickly. While cheaper substances are available, you should coat your metal roof with special roof coating preparations -- these substances are specially designed to be able to handle the normal expansion that occurs when a metal roof is heated.
