Shingles Bubbling? Know How To Fix Them

A problem with asphalt shingles is that they can absorb water and expand. While normal expanding and contracting occurs due to the weather fluctuations, the water can cause issues with blisters and bubbles on an asphalt shingle. If you let an asphalt shingle roof fall into disrepair, bubbling will eventually happen to the roofing material. These bubbles are not only a problem with the roof's aesthetics but can cause structural problems from water getting into the roof deck, such as roof leaks and a damaged interior. Thankfully, it's easy to get rid of bubbles in asphalt shingles if you follow these tips.

Get The Tools

Only a few tools are needed to repair those bubbling asphalt shingles. You'll need the following items:

  • Utility knife
  • Roofing cement
  • Putty knife
  • Spare asphalt shingles

Cut Out The Bubble

You'll want to cut out the area that is bubbling up with your utility knife. The cut should go an inch or two past where the bubble is, giving you a completely flat area to repair rather than one that is raised. Be careful when cutting into the shingles, since going too deep could cause damage to the felt underlayment, which will cause more bubbling.

Apply Roofing Cement

Use your putty knife and apply roofing cement to the area that you just cut out, going past the hole and an inch or two onto the shingle in every direction. It will give you a big surface to stick a patch onto later.

Cut And Place The Patch

Next, you'll need to cut out a patch using an extra asphalt shingle that you have, helping it match the existing color of your roof. The patch must be larger than the hole that you are sealing, so try to match the size of the area the roofing cement has been applied to.

Put pressure on the patch so it forms a tight seal. You'll then need to apply more roofing cement to the edges of the patch so that it will not let any more water in from the sides.

If these steps feel too difficult to you, or you don't want to perform the work up on your tall roof, know that you can always hire aroofing company to handle it all for you. If you do not have extra shingles, they can even help you source replacement material that will match the existing color and texture of your roof.
