Installation of metal roofs over old wooden shingles is a great way for roofing contractors to assist building owners in saving on roof repair costs and to optimize the lifespan of the new roof. A well-installed metal roof is also used to add visual curb appeal to a structure since they come in such a wide variety of colors and styles. If your home or business has undergone roof repair work in the past, you may be interested in learning how to install metal roofs over wooden shakes. There are a few things to keep in mind when doing this procedure to ensure the installation goes smoothly and that no further damage is done to the roof.
The first step in how to install metal roofing is to get a few quotes from local roofers. This will allow you to compare pricing options before contacting a contractor. Find a handful of estimates and then call each one to get a written estimate of the price. This step is especially important if you are installing the roof over a wooden shake. Wooden shakes can crack, warp, and buckle under extreme weather conditions so if you’re installing over a wooden roof you’ll want an accurate price quote.
The second step in how to install metal is preparing the roof for the installation. Remove all of the insulation from inside the roof. This includes any tiles that have felt installed on the roof and any foam insulation that may have stuck to the ceiling and inside the walls. After removing these materials, the roofing company will preheat the roof by dipping steel wool into a bucket of hot water. After everything has been heated through the addition of oil, the roofing contractor will place insulation sheets on the roof and then install the metal shingles following this process.
The third step is actually installing the metal roofing itself. This can usually be accomplished with two different methods. Either slotting or spinning the panels together can work depending on the type of shingle you are using. Most installing will follow slotting procedures but it is always good to have some practice in case your method does not work as smoothly as you’d hoped. If you are installing standing seam roofing, it is critical to make sure that the panels fit tightly together.
The final step in the learning process is attaching the metal panels to the roof. This can often times be done using nails or screws. Make sure that you nail or screw each nail into the sheet metal carefully. Also check and double check to ensure there are no leaks. After all of your nails are in place, your last step is to place a hail screen over the roof to help prevent damage from occurring to the roof. Hint: try to avoid installing standing seam roofs in areas with heavy snow or hail because the roof could easily take an impact from these objects.
When you are done with installing the panels, you can then go ahead and attach the shingles. The easiest way to attach them is with a special glue that you can purchase at any hardware store. Special instructions should be discussed with a contractor during the install.
