You should make sure your roof is in good condition to prevent water leaks during rain and snow melts before the hardest parts of winter arrives. Wind storms during the fall can cause tree branches to crash against your roof and damage the asphalt shingles. If asphalt shingles have been torn or ripped off, you'll need to remove what's left of the damaged shingles and replace them with new shingles as soon as possible. Here is how to replace damaged asphalt shingles on your roof.
You Will Need:
- New Asphalt Shingles
- Small Flathead Pry Bar
- Paint Brush
- Roofing Nails
Step One: Remove Damaged Shingles
Slide the flat end of the pry bar under the damaged shingles and gently break away the tar adhesive strip that holds the broken shingles down on top of undamaged ones. Then break the adhesive strip between the damaged shingles and the ones above it. You will be able to lift the shingles up once the adhesive strip is removed.
Now, remove the nails holding the damaged shingles to the roof. Slide the pry bar back under the damaged shingle and push it against the nails holding it down. Gently lift up to pop the nails lose. Carefully lift up the undamaged shingle on top of the damaged one and pull the nail with the forked end of the pry bar. Be careful not to bend the undamaged shingles too much when you lift up or you can put cracks in them.
Remove the damaged shingles.
Step Two: Purchase Replacement Shingles
If you want the shingles to have a uniform look on your roof, you'll need to purchase replacement shingles that match the size, color, and texture of the shingles already on the roof.
Take a section of the broken shingle with you to a roofing supply or hardware store so you can match it up to the shingles to the ones the store has in stock.
Step Three: Install New Shingles
Slide the new shingles into the space vacated by the damaged ones.
Hammer in three of four roofing repair nails along the center of the shingles.
Step Four: Apply Tar
You'll want to make sure you replace the adhesive strip with some new tar or roofing cement. The adhesive strip helps to hold the asphalt shingles down during period of high winds that could get under the shingle and rip it off your roof.
Take a small can of roofing tar and dip a paint brush in it. Apply a liberal amount along the center of the asphalt shingles under the replacement shingles – this strip was broken when you removed the damaged shingles.
Press down on the shingles after applying the tar to help the shingles bond together.
