Metal roof installation is fairly simple. Just try to take into account a few basic steps, and you will easily manage to carry out the task yourself. A metal roof is considered to be a very resistant kind of roofing. It also has the advantages of being waterproof and fire resistant, which is why several buildings are reinforced with this type of roofing.
Step 1: Measuring and Acquiring the Metal Panels or Shingles
Start off by measuring the area of your roof. Metal roofing is usually made from a number of metal panels or shingles. These will vary in sizes, so you will need to describe the area of your roof to the manufacturer or supplier so you can purchase the appropriate amount of shingles or panels. It is a good idea to draw a picture of the area of your house from a bird's eye view, and mark the dimensions on it for future reference.
Make sure to select good quality metal panels or shingles so as to further ensure longevity and lower maintenance needs. It is a good idea to make a thorough search so as to select a reputable company.
Step 2: Prepare the Foundation
It is crucial to prepare the foundation prior to installing the metal shingles or panels. Some roofing systems supplied will be made in such a way that you can directly install them onto the existing roof. The most vital thing is that there is a solid sheeting as a foundation for the metal roofing, so make sure you carry out any necessary maintenance to ensure this. Otherwise, you may consider a complete tear off of the existing roof if there are various patches that make maintenance or repairing not worthwhile.
Next, install the roofing underlayment. This is usually best laid out in horizontal format by nailing it in place until the whole roof area is covered up.
Step 3: Install Metal Flashing
Next, you can start installing the metal flashing at the edges of the roof. This is secured using special screws. Keep installing flashing around all the eaves of the roof.
Step 4: Installing the Metal Panels
Now you can start installing the metal panels. Slightly bend the edge of the first panel so as to install it underneath the trim by screwing it in place as neatly as you can. It is a good idea to have someone hold the panel for you. Most manufacturers make panels that interlock in one another, so the next panels you install will have to be fixed in such a way that they lock into each other at the seams. Brackets and screws fixed at every few intervals will further secure the panels into place. Keep working until all the roof has been covered.
Step 5: Install Gable Flashing
Finally, you can install gable flashing to neatly cover up the sides and edges of the panels.
