Reasons That Individual Roof Shingles May Need To Be Replaced

Posted on

When you think of having your roof replaced, you might often think about each of the old shingles being pulled up and replaced with new ones. While this will be necessary at some point, you might also require the replacement of individual shingles. Even if just a handful of shingles need to be replaced, this isn't something that you should ignore. Water can leak into your attic when just one shingle has a problem, so as soon as you notice an issue with a shingle, you should call a licensed roofing contractor at a company like 5 Star Roofing to have them visit your home, assess the problem, and replace whatever shingles need it. Here are some reasons that individual shingles may need to be replaced.

Loss Of Granules

The granules on each of the shingles play a role in repelling water. Individual shingles may be at risk of losing their granules for a number of reasons, but a common one relates to the presence of tree branches. For example, if a tree's branch hangs over your roof and makes contact with it, the branch can eventually rub the granules off one or more shingles. The absence of the granules, fortunately, will often be visible from your yard when you're looking at your roof.


The bottom edges of your roofing shingles may also be at risk of curling. While this is common when the roof reaches the end of its life, individual shingles may also be at risk of curling prematurely. This can arise due to contact from tree branches, as an individual branch may slowly work its way under the bottom edge of a shingle and curl it upward. Shingles may also curl if their nails work themselves loose over time. A curled shingle doesn't have the integrity of one that is flat against your roof, so you'll want your roofing contractor to replace any shingles with this issue.


You may also notice that some of the shingles on your roof are cracked. This can occur after cupping. For example, if one edge of the shingle is cupped upward, a crack can eventually develop between the cupped corner and the corner that is still properly nailed down to the roof sheathing. As with the other problems, cracking reduces the integrity of the affected shingle and may begin to allow water to seep beneath it. For this reason, you'll definitely want to have any cracked shingles replaced promptly.
