How to Repair Roof Shingles

If you’re a homeowner, you know how important it is to keep your home in good condition. One area that often needs maintenance is the roof. Over time, shingles can become damaged due to weather conditions or general wear and tear. If left untreated, this damage can compromise the integrity of your roof and even lead to leaks. But don’t worry, repairing roof shingles is a task that can be easily tackled with the right tools and knowledge. In this post, we’ll provide you with a step-by-step guide on how to repair roof shingles so you can keep your home safe and secure.


How Often Should You Replace Your Roof Shingles?

If you notice any damage or wear, take immediate action. This will prevent water from seeping through the shingles and rotting the wood beneath. Ignoring any problem, no matter how small it may seem, can lead to a costly roof replacement that could amount to hundreds of dollars.

You should consider replacing your roof if it is older than 20 years and the majority of shingles have been damaged or worn out. If your roof is in essentially good condition and has a shallow pitch that you are comfortable with, you may be able to perform most of the repairs yourself.

We’ll now guide you through the three most common methods: replacing asphalt roof shingles, securing a badly curled shingle, and repairing cracked shingles.

1. Replacing Roof Shingles

Materials Needed:

Step 1: Prepare Tools and Materials

Gather all the required tools and materials, including the hammer, flat pry bar, utility blade, roofing nails, and replacement shingles. Make sure you have everything ready before starting.

Step 2: Remove Nails from the First Row

  1. Position the flat pry bar on the damaged shingle’s edge.
  2. Press down on the pry bar and slide it underneath the shingle to expose the roofing nails.
  3. Gently lift the shingle above the damaged one using the pry bar and slide it underneath. This will reveal the first row of shingles beneath.
  4. Using the pry bar, insert it under the damaged shingle and gently pry it upward. Stop when the nail rises about 1/4 inch.
  5. Press the damaged shingle downward to free the nail.
  6. Repeat this process for all the nails in the first row.

Step 3: Remove Nails from Second Row

  1. Move on to the second row of shingles above the damaged one.
  2. Insert the pry bar under the shingle immediately above the damaged one.
  3. Repeat the process of gently prying the shingle upward until the nails are raised about 1/4 inch.
  4. Press the shingle downward to release the nails.
  5. Repeat this process for all the nails in the second row.

Step 4: Remove the Damaged Shingle

  1. Once you have removed all the nails from both the first and second rows, carefully pull out the damaged shingle from its position.
  2. Dispose of the damaged shingle properly.

Step 5: Prepare Replacement Shingle

  1. If the damaged area is larger than a single shingle, you’ll need to replace the entire shingle.
  2. If you have leftover shingles from a previous repair, use those. If not, obtain replacement shingles that match the existing ones as closely as possible.

Step 6: Install Replacement Shingle

  1. Slide the replacement shingle into the vacant space left by the damaged shingle.
  2. Align the replacement shingle with the surrounding shingles to ensure a seamless appearance.

Step 7: Nail Down Replacement Shingle

  1. Carefully hammer 1 1/4-inch roofing nails through the replacement shingle, securing it in place.
  2. Make sure the nails go through the edges of the replacement shingle as well as the shingles in the row above.

Step 8: Complete Installation

  1. If you need to replace additional damaged shingles, repeat the process for each one.
  2. Once all damaged shingles are replaced, ensure that the new shingles are securely nailed down.

Step 9: Clean Up

Dispose of any debris, old shingle pieces, and unused materials properly.

By following these steps, you can effectively replace damaged roof shingles and maintain the integrity of your roofing system.

2. Fix Curled Roof Shingle Corners With Caulking

Materials Needed:

  1. Slide the new shingle into position, aligning it with both sides.
  2. Asphalt shingles’ corners will often curl upward or downward as they age. To prevent the inevitable curling of a shingle, you can adhere to the curled part.
  3. Apply a small amount of roofing sealant using a caulking tool (which costs about $4 for a 10-oz. tube) under the corner. Place a weight, such as a brick, on it (as shown on the right) and leave the weight on for at least 24 hours until the sealant has dried. 

3. Cracked Roof Shingles Repair

Materials Needed:

  1. Carefully lift the upper shingle and secure the new shingle in place using roofing nails.
  2. You don’t need to replace a shingle that is cracked or torn; you can simply repair it. Apply a thick layer of roofing sealant underneath the crack. Then, apply a second bead of sealant on top of the cracked shingle. Use a putty blade to spread the sealant evenly.
  3. Look for colored granules in the gutter that were washed off the roof by the shingles. Collect some of these granules in a cup and sprinkle them over the sealant.
