Some roofing shingles are sold with a thirty, forty, or even a lifetime warranty.
While a longer warranty is definitely a benefit, most roofs will need to be replaced long before the warranty has expired. A roof will normally last no more than twenty-five years. Some may need replacing around ten to fifteen years but most need to be replaced around twenty years. Although some shingles are better quality and do tend to last longer, a harsh environment will cause a roof to age more quickly. Heavy storms and intense heat are factors in what is causing your roof shingles to curl.
With every growing technology, roof shingles installed today will most likely last longer than roofing shingles installed twenty years ago.
But basically, things just wear out. If your roof is over ten years old, be proactive and check it periodically for curling shingles and other possible signs of wear and tear. While most manufacturers strive to make a quality product, there are times where they have missed the mark.
As a result, some shingle companies have been in the news and involved in class-action lawsuits around the country. In some cases, the shingles started to curl shortly after they were installed. In that situation, the manufacturer stopped making and selling the defective roof shingles.

Rather than completely removing the defective roof, some homeowners will install a new roof over the top of the damaged roof.

This means the new roof is more susceptible to curling and buckling sooner than expected. The old roof was probably replaced due to some sort of damage. If that damage was rot or mildew, it may still exist and cause damage to the new roof as well.
There are times when repairing parts of a roof makes more sense than replacing the whole roof. If you are trying to decide which route to go, consider the amount and size of the damage as well as the age of the roof.
If you have lost a few roof shingles due to heavy winds or a strong storm, repairing your roof and replacing those few damaged shingles may make more sense.
If, however, there is damage to your roof shingles like curling, you want to consider the underlying cause of the damage. Before making your decision, you should consider the age of the roof as well. If you are unsure which direction to go, contact a roofing professional for an estimate.
If the damaged roof shingles are in one large area, or several smaller areas, you should consider not only the age of your roof but also the aesthetics. Your roof is a very visible part of your house.

Repairing a small section of your roof when the damage was caused by strong winds is different than repairing a section that has curling roof shingles.

Depending on the situation, it may be acceptable. Most local building codes allow for two layers of roof. More than two roofing layers can damage the framework and structure of the house.
While it may seem like a cheaper way to go, adding another layer over the current roof, will most likely end up costing you more money. When you are considering repairing a section rather than replacing the whole roof, you want to weigh the overall costs. Labor costs: The installers will already be working on your roof.
