Asphalt shingles may look nice and seem easy to install but metal roofing is far better. It can weather the elements for years, even decades, to come. Metal roofing sheets are normally created using aluminum or stainless steel sheets hence, the durability. Now, if you have existing asphalt shingles on your roof that have worn out its welcome, you may want to consider replacing them with metal roofing. If this idea is interesting for you, then here are some steps on how to install your new roof.
- Removing the shingles. Obviously, the first step into making the switch into metal roofing will be to remove the existing shingles on your roof. To do this, get up there and bring a crow or pry bar. Use the bar to pry the nails holding each shingle in place. This is a tedious and tough job so make sure to get some help to speed up the process. Once each shingle has been removed, bring them down and proceed to inspecting the rest of the roof. If the roof has damage underneath, then consider repairing it. If there are nails or pieces of cracked shingles still in place, remove them as well. Also, remove the existing underlayment as well. The roof surface should be clear of any remnants of former material. In addition, it should be clean as well. This means that you will need to remove twigs, leaves, and any other debris on it. Once free, clear, and repaired (if necessary), you can proceed with the metal roof installation.
- Install the new underlayment. Roof felt will be your primary underlayment material and will serve as the second layer of protection from the elements. With the roof clean and clear, layer on the underlayment one strip at a time. It should be done in an overlapping fashion with each strip secured by nails or staples. Make sure to cover the entirety of the roof.
- Install the metal rolls. With the underlayment already in place, take your metal rolls and install it one roll at a time. Overlapping will be required as well. Also, you will need to have the lap edge of the roll pointing up since you will connect this with the lapped edge in order to seal the top part of the roof. If the roof is flat or low pitched, then you may not need the lapped edge. The other edge of the roll should be positioned so that it is on an overhand. This is important to allow the water from the rain to trickle down into the gutters. As you lay on each metal roll, secure it in place with galvanized nails, the drilled kind. You may need to use a sealant to seal each nail.
As soon as you complete the project, the next phase would be painting
the metal roofing. This, of course, will only be required if you chose a
plain metal roll. In any case, there you have it, your new metal
roofing. Now, the process will be easier if you have someone with
know-how guiding you on your first run. If you have the money, consider
having a roofing contractor take care of the work as you observe and
study how it is done.
