Replacing cracked roof caps

Roof caps are the highest parts of your roof. They are covering the sides of the roof. Sometimes, because of high winds they can get damaged and will need to be replaced in order to avoid further damage to your house.

You will need the following tools:

  • Saw Horses
  • Plywood
  • Shingles
  • Straight Edge
  • Hammer
  • Utility Knife
  • Roofing Nails


First of all you will need to create a work surface. Set up a sawhorse and place a section of plywood diagonally to them. You will also need to place down the shingles on the work surface and keep the tabs in front of you with the asphalt facing the top part.


You will need to cut the shingles right to the top in three pieces at every slit to break the first tab from the other two. Keep cutting until you have three tabs. See how many you will need to replace the missing caps.


Use a knife to remove the top corners. This will help you slide the tabs under the previous ones. Only the asphalt sections need to be seen on the roof cap.

Sliding the cap

Now glide the cap shingle right beneath the asphalt end of the next cap and raise the end of the shingle. This will allow you to nail each side of the replacement.


Now it’s time to fix the replacements with nails at a distance of one inch. Remove the clear tape from the tar strip.
