Now, to begin learning how to install metal roofing, we strongly recommend that you read through these very easy steps:
1. Get rid of the old material.
The initial task in how to install metal roofing is getting rid of the previous roofing, including all the nails. You can do this by using a pitchfork or shovel. Upon clearing the roof surface, you have to sweep the entire area with a broom to prepare it for the next step.
2. Roll out the roofing felt.
A 30-lbs. roofing felt needs to be laid out on the entire roof surface. Make sure the each sheet overlaps the previous one by a couple of inches, and that you leave about 3 inches hanging over each edge.
3. Create guidelines on the felt.
Draw parallel lines going from the crown of the roof to the gutter at two feet intervals from one another. You can do this using a chalk line. These straight lines will serve as guidelines when you are placing your metal sheets on the roof.
4. Attach the metal sheets.
If you feel you are confident enough and really know how to install metal roofing, then get ready because this is the biggest and most exciting part of the construction – installing the metal sheets. First, you have to cut a length of metal roofing equal to the distance from the crown to the edge of the roof, adding a couple of inches for the overhang. If you really want to learn how to install metal roofing, you also need to learn to measure accurately.
Lay down the first metal sheet on the leftmost side and attach it to the roof frame with screws every two feet. Repeat the same procedure for the next sheets until you have covered the whole roof. Make sure that each metal sheet overlaps the one beside it by about 2-3 inches.
5. Plug up the gaps.
Use a rubber strip to plug the lines where the metal sheets overlap. This will keep insects and other small animals from burrowing into your roof.
6. Attach the metal edging and cap.
