How to Put Down Metal Roofing


Metal roofs are quickly becoming one of the more popular roof choices for its durability and aesthetic value. Metal roofs are fire-resistant. Homeowners can even get an insurance break if the house they live in has a metal roof. Tin, aluminum, copper and steel are a few of your choices. Some people even intermingle a few different metals onto one roof. In the past, metal roofs were usually only found on commercial buildings, but recently more residential homes are discovered with a metal roof.

Things You'll Need

  • 30-pound felt
  • Slap stapler
  • 1/2-inch staples
  • Chalk line
  • Tape measure
  • Tin snips
  • 1-inch sheet metal self-tapping screws
  • Screw gun
  • Self-stick rubber strips
  • 3-inch metal edging
  • Metal ridge cap
  • Apply a 30-pound felt moisture barrier over the entire roof. Secure the paper with a slap stapler and 1/2-inch staples.

  • Draw straight, parallel lines from the ridge of the roof down to the gutter using a chalk line. Draw the lines 2 feet apart. These lines are your guide for laying down your sheets of metal roofing.

  • Measure and cut 2-foot sheets of metal roofing material the length of the distance between the roof ridge and the roof edge with an additional 2 inches for the overhang. Use manual or electric metal tin snips.

  • Put down the first metal roofing sheet on the far left side of the roof and adhere it to the roof rafters every 2 feet vertically. Use 1-inch self-tapping sheet metal screws and a screw gun.

  • Continue putting down one sheet of metal roofing at a time, overlapping each sheet by 2 inches.

  • Cut strips of self-stick rubber strips to lay down over the seams of the metal roofing sheets. The rubber strips plug up the gaps, preventing water and creatures from getting inside your roof.

  • Install a 3-inch metal edging around the perimeter of the roof with self-tapping screws, and place a metal ridge cap over the ridge also with self-tapping screws.

Tips & Warnings

  • Make all of your cuts prior to putting down the roof. This will save you time.
  • Wear a pair of heavy-duty gloves to protect your hands from the sharp metal roofing material.
