How to Install Metal Roofing Panels

Installing metal roof on your home is a great way to extend the life of your roof. By replacing older, weaker shingles with metal roofing, you may also save money on the ongoing cost of a complete roof replacement, spare yourself the labour of removing the existing roof, and reduce the time it takes for you to install a brand new roof on your property. How to Install Metal Roofing Over Shingles – Part 1 – To begin, check the condition of your existing roof. If it needs repair or maintenance work, it is likely that your metal roof will also need improvement. You should check to ensure that there are no breaks in the shingles.

The first step in how to install metal roofing is to remove your existing roof. If you’re doing this on a small roof (around roof ten feet by ten feet long and less than an acre), all you’ll need are some tools and a hammer. Otherwise, if you have an old asphalt roof on a larger roof, you may need to hire a contractor to come out and take measurements, hire a friend to help lift the heavy tacks that may be hanging down or use a crane to remove it. Do not attempt to lift the entire roof on your own! Also, make sure that whoever is doing the work has the proper equipment and knows how to install underlayment correctly.

Next, review your options for metal roof over asphalt shingles. Some of your options include single metal shingle, double metal shingle, spiral metal shingles (which look like little rice paper), wool shingles and even ceramic shingles! Each of these can be installed on its own or in combination. If you do not know how to install metal roofing using one of these products, your best bet is to hire a contractor or the services of an expert. A professional would also be able to tell you how many layers to buy and how to bundle them to ensure maximum effectiveness.

Once you have decided what kind of product you want to install, the next step in how to install metal roofing is to determine whether or not you need flashing around the base of the shingles. Even if you have the traditional single or double-sided shingled system, sometimes additional flashing is needed to cover areas where rain, snow or heat might penetrate the shingles. If the roof is old, your existing roof probably already has this type of flashing installed. If your old roof is metal instead of wood, however, you will probably need to purchase flashing that matches your metal roof exactly.

For those who are installing single shingled metal systems, the next step in how to install is to check for any possible problem areas. For example, if there is hail or ice damage in the attic, check the valleys between the shingled layers for possible leaks. If you discover such a problem, the area must be sealed using thick enough exterior concrete to completely protect both the flashing and the underlying roof.

When you have found all the appropriate flashing and sealed the area, the next step in how to install metal roofing panels is to carefully nail each panel to the previous layer. You may want to use a longer nails and use smaller nails, depending upon the overall size of the panels. The final step in how to install metal roofing panels is to overlap the panels a little bit to make sure water will be prevented from leaking between the layers. This can be done with a nail, chisel or pry bar. Once installed, your roof should provide the protection you need against severe weather and expensive repair or replacement.
