Add the Metal Panels Finally, install the metal panels (Image 1), placing metal closures on the top and sides of the roof structure to hold the panels in place. Secure them with clip fasteners (Image 2), not screws, penetrating the metal panels themselves. The panels that make up the roof fit together like pieces of a puzzle — snug and tight.

A steel roof is expensive, but if it lasts the life of your home, it might be worth it. The type we show here costs about twice as much to have installed as a new asphalt roof. But some steel shingle manufacturers offer do-it-yourself systems that cost about the same as an installed asphalt roof. These systems aren’t attached to a frame, but instead install directly on the old roof. Consequently, they don’t have the same ventilation advantages.

Remove all of your old shingles and paper, down to the roof planking, before installing the tin roof. The process you will use to remove the shingles will depend on their type. For instance, you can use a pry bar or shingle ripper and the appropriate safety gear to remove asphalt shingles. Then, use new tar paper or felt to line the roof.

The gauge of the metal is a measurement of how thick it is. The smaller the number, the thicker the metal. 24 gauge metal (sometimes written “24ga”) is thicker than 29 gauge, which is the minimum recommended gauge for residential construction. Some roofs, such as Modular Press Formed Granular Coated roof, are only available in certain gauges (26 gauge in this case). 24 gauge is the recommended gauge for high wind areas. The gauge of the roof doesn’t affect the overall price much. The difference is usually a matter of around $100 per square. (A “square” in roofing is a 100 square foot area.)

When comparing asphalt with metal, the durability of a metal roof is its crowning glory. A roof that will probably outlast its owner is a good investment. Asphalt is more economical, and that’s why it has the majority of the residential market at the moment. When metal becomes more economically viable, that may change. However, for now, asphalt is king.

According to the 2014 US Census, the average square footage of the average American roof is 1700 square feet. Calculating the cost of a metal roof isn’t as simple as just knowing your square footage, however. The price of metal is subject to fluctuation. Sometimes it can be pretty volatile. (In 2007, steel had a very wild period in which quotes for steel prices were good only for one hour!)

Install slat boards to the roof so that you can easily attach the new tin. Lay the slats at 2-foot intervals length-wise, as you work from the roof’s bottom and upward. Secure the slats with 3-inch metal-to-wood screws. Then, nail the metal edging by using a hammer and roofing nails.

Can you avoid tearing off your old asphalt shingle roof by putting a steel roof over it? Maybe. Most codes now allow no more than two layers of roofing before requiring a complete tear-off. So, if your roof has two layers, it may require a complete tear-off, even though steel is lighter than asphalt. Codes vary, so call your local building department to get the straight story.

The last panel will need to be cut to fit when you reach the roof edge. Wear the proper safety gear, like gloves, and use metal snips to cut it. Mark the ridge or crimp that runs along the roof edge with a chalk line to guide your tin cutter and cut before screwing the last panel in. Then, repeat this step for the other side.
