How to Install Metal Roofing

Metal roofing may be more expensive than normal roofing systems, but the benefits outweigh the costs. Metal roofing is very protective from the outside elements and can help with cooling your home because it reflects the sun's rays. Follow these steps to install your own metal roofing.

What you will need:

• Stepladder


• Extension ladder


• Measuring tape


• Chalk line with orange chalk


• Drill with three types of bits: regular bit, 5/16 inch bit for screw head, 1/4 inch screw head bit


• 5/16 inch lap screws made of metal


• 1/4 inch screws made of wood


• Heavy duty hammer


• Half-a-pound of 1 1/4 inch nails


• 10 pounds of 3 inch long head screws


• Snips for metal cutting


• Nail bag


• Roofing felt or 30 pound tar paper

1. Measure the height of your roof and add two to four inches for the overhang. For the metal edging, measure the length and height of the roof.


2. Measure trim pieces.


3. Use square feet measurements to measure shingles. Add 3 to 6 inches for airflow.


4. Remove old shingles.


5. Spread your roofing felt or 30-pound tar paper to create a base.


6. Use 1/4-inch roofing nails to nail the metal edging around the roof.


7. Place sheeting from top to bottom.


8. Use 1/4-inch screws and install the metal sheets every two feet.


9. Install the next set of sheets to overlap the first ones installed.


10. Repeat this process until the entire roof is sheeted.


11. Install metal trim every two feet using 1/4-inch metal wood screws.
