How Often Should Shingles be Replaced?

As an experienced roofer, I often notice serious problems with shingles that homeowners are otherwise oblivious to. Maybe it’s because I have a trained eye for these things after so many years in the roofing business. However, sometimes I come across damage that’s an eyesore from a block away.

Sometimes homeowners don’t notice problems with their roofs until it’s too late. Here in San Antonio, the sun and other weather conditions can cause damage to shingles that may start out as minor flaws before turning into major construction projects. That’s why it’s important to know when your shingles have had enough and it’s time to replace them. 

Shingle Curling

The sun’s UV rays that shine over Texas homes are no joke. They can damage your shingles by creating tiny cracks in them over time. These cracks tend to expand more as the shingles become drier over time. When you start noticing any type of curling around the edges of shingles, it’s time to replace most of them.

Abnormal Growths

Any type of plant or fungi growth on shingles, whether it’s moss or spores, is a telltale sign that they need to be replaced. Once these growths get within the small cracks of shingles, they can promote moisture that often leads to internal damage. This damage might not be noticeable at first, but you’ll start seeing shingles falling apart shortly after this.

Loss of Granules

The granules that cover shingles are not just for aesthetic purposes. They help protect the shingles from the outside elements. However, sometimes these granules begin to wear away when they themselves are affected by the environment. When this happens, the roof can become damaged by wind and rain, which is why you should always consider replacing shingles when you notice this.

Signs of Old Age

Lastly, shingles in Texas typically last around 15 years (give or take). If you want to be proactive, having your shingles inspected when you know they’ve reached their senior years is normally a good idea. This is a preventative measure for those who prefer to take action before a problem gets out of hand.

If there’s no noticeable damage, then you may not need to replace your shingles anytime soon. If any damage is found, you might just catch the problem early before a full restoration is needed.
