Tips for Repairing Damaged Asphalt Shingles

Repairing and replacing asphalt shingles is fairly easy and being able to effectively maintain and repair your asphalt roof yourself can save you a lot of money too. A damaged asphalt shingle can cause leaking into the building, quickly causing major damage and demanding high cost repair bills. Getting on to the problem quickly will help to prevent further damage and can save you a lot of money too. A damaged asphalt shingle should generally be replaced rather than attempting repairs on it. The replacements do not cost much and with a few basic tools and materials, it is often easier just to replace the damaged shingle. This article provides some tips and instructions on repairing, removing and replacing broken asphalt shingles.

Tools and Materials Needed:

  • Replacement shingles
  • Pry bar
  • Utility knife
  • Roofing nails
  • Plastic roofing cement
  • Ladder
  • Claw hammer

Making Preparations

Before you begin, make sure that the ladder is standing on a flat and firm surface. You may also want someone to hold it for you for extra stability. Ensure that the weather is completely dry as is the surface of the roof before carrying out the repairs. Do the job on a day when the forecast is good and for dry weather.

Removing the Damaged Shingle

To remove the damaged shingle, you will need to lift up the two shingles which overlap it from above. Use a flat pry bar to lift the shingles. The shingle that you want to remove will be held in place by a self-adhesive strip which will need to be broken by sliding the pry bar all the way through it. This needs to be done with great care as it is very easy to damage the neighboring tiles or the roofing felt beneath.

The nails which hold the damaged shingle in place and the shingle above it will also need to pried out using a claw hammer. As in the previous step, take extra care not to damage other shingles or the roofing felt below. When you have detached the self-adhesive strip and removed the nails holding it in place, you should be able to slide the damaged shingle out of place.

Take the damaged shingle to your local home improvement store and find a matching piece to replace it. It is always a good idea to keep a few spares handy in the future as well.

Installing Replacement Shingles

Reversing the manner in which you removed the old, broken shingle, put the new one in place. Attach it to the roof using the self-adhesive strip on the back of the tile and then nail it in place.

Repairing Shingles

Rather than removing and replacing a damaged shingle, you can often simply place a new shingle on top of the broken one. This saves a lot of work and is actually recommended by many roofing experts, especially with regards to tiles installed on the ridges of the roof.

In other cases, shingles can be simply repaired by replacing the nails or applying a new layer of roofing cement beneath it.
