Easy Solution for Patching Roof Shingles: Assess The Damage First

Most homeowners will skip this step and assume they need to fix the damaged portion — not so fast, it’s crucial to assess the extent of the damage and identify other areas that require repair.

Follow these steps to assess the damage:

Easy Solution for Patching Roof Shingles: Assess The Damage First

  1. Visual Inspection: Carefully inspect your roof for any signs of damaged shingles. Look for curled, cracked, or missing shingles and signs of water damage or leaks.
  2. Check Surrounding Shingles: Examine the shingles surrounding the damaged area. Pay attention to any curling or lifting at the corners, which may indicate underlying damage.
  3. Evaluate Moisture Barrier and Flashing: Check the moisture barrier and flashing in the damaged area for any signs of damage or deterioration. Addressing these issues is essential to prevent future leaks.
  4. Consider Overall Roof Condition: Assess the overall condition of your roof. If the surrounding shingles are old, brittle, and dry, re-roofing the entire area may be more cost-effective than replacing individual shingles.

Now that you have assessed the damage and identified the areas that require repair, it’s time to remove the damaged shingles.

Follow these steps to ensure a safe and effective removal process:

Remove Damaged Shingles Simple Steps for Roof Shingle Repair

  1. Safety Precautions: Prioritize safety by practising proper roof safety measures. Wear protective gear, secure your ladder, and work with a partner whenever possible.
  2. Cool Weather Removal: Choose a cool day to remove the shingles, as asphalt and sealant are more pliable and easier to remove in cooler temperatures. If working in hot weather, wetting the shingles can help cool them down and make them more manageable.
  3. Breaking the Adhesive Bond: Use a pry bar or a hammer claw to carefully loosen the adhesive bond between the damaged shingle and the roof. Start by lifting the corners and gradually work your way towards the center.
  4. Removing Nails: Once the adhesive bond is broken, remove the four nails securing the damaged shingle. Slide the pry bar under the shingle and lift it to expose the nails. Carefully pry the nails upward to remove them from the roof deck.
  5. Removing Adjacent Nails: In some cases, nails from the shingles above the damaged area may penetrate the upper edge of the damaged shingle. Repeat the adhesive bond-breaking step on the asphalt shingles two courses above the damaged area and remove the nails from the shingles in the course immediately above.
  6. Complete Shingle Removal: Once all the nails are removed, gently lift and remove the damaged shingle. Be cautious not to damage surrounding asphalt shingles during the removal process.

  3. Securing the Shingle: Use adhesive or cement to secure the replacement shingle in place depending on the shingle type. Follow the manufacturer’s instructions for the specific adhesive or cement you are using.
  4. Nailing the Shingle: Once it is secured with adhesive, use roofing nails to secure it further. Place nails in the designated nail slots or pre-cut holes, ensuring they penetrate the replacement shingle and the underlying roof deck.

Efficient Ways to Patch a Shingle Roof: Repair Cracked or Split Shingles

It’s possible to repair cracked or split shingles without removing them entirely. If that’s the case, here’s the most efficient way to do so:

  1. Identifying Cracked or Split Shingles: Inspect your roof for any cracked or split shingles. These shingles can often be repaired without complete removal, just by patching them with some sealant.
  2. Applying Roofing Sealant: Use a roofing sealant or adhesive to repair the cracked or split shingles. Apply a thick bead of sealant along the crack or split, ensuring it fills the entire length of the damaged area.
  3. Pressing Shingles Together: Press the cracked or split shingles together to seal the adhesive or sealant. Hold them in place for several seconds to ensure a secure bond.
  4. Camouflaging the Repair: Check the gutters for colored granules that have washed down from the damaged shingles. Collect some of these granules and sprinkle them over the sealant to camouflage the repair and blend it with the surrounding shingles.
