Blown-off shingles can cause significant structural damage to your home. If a roof isn’t fully covered with shingles, strong wind gusts can rip them away. Also, water damage can become an issue when gaps develop in the roof.

Curled shingles are usually the result of moisture buildup and poor ventilation in the attic. If you notice curls on your roof, know that it is a symptom of a bigger problem that needs immediate attention.

Leaks are a common problem on roofs. Their telltale signs — water puddling on the shingles — are often visible from the ground. But underlying causes can vary widely, and the solutions might be as simple as installing a new flashing or as complex as repairing your entire roof.

Poor workmanship is one of the most significant contributors to roofing problems. If your roof shows signs of leaks just after the new installation, it’s time for some roof repair.
