What if you need to replace the drip edge on an existing roof or install a drip edge on an existing roof for the first time? It can be done; here’s how:

  • Step One :Gently lift up the shingles on the edge of the roof and locate the nails holding the existing drip edge onto the roof.
  • Step Two :Use a flat pry bar and hammer to pry the nails out of the drip edge gently.
  • Step Three :Once free, slide the drip edge out and discard.
  • Step Four :Install the new drip edge as described above, with cement and nails. You’ll need to ask another roofing professional to hold up the shingles while you do so.

Just as with installing drip edges on new roofs, you should check with your local building codes to see if there are special rules you have to follow about drip edge replacement.

In years past, many building codes did not require drip edges; but the roofing community realized that these relatively inexpensive products make a big difference in the performance of the roof. By installing drip edges properly, you’ll be giving your customers a better roofing system.

If you’ve discovered your roof is missing a drip edge, or has a damaged drip edge, you can get in touch with a roofing contractor through our Roofing Contractor Locator to get professional advice.
