What Curling and Buckling Shingles Mean for Your Roof

Have you noticed any damages to your Florida residential or commercial property roof? Damaged roof shingles may curl, buckle, and/or fall off. There are numerous reasons that your roofing shingles may become damaged, including weather, age, and human errors.

Curling or buckling shingles indicate that major issues may exist. It is imperative that you replace damaged shingles immediately to protect your property’s structural integrity. As roofing shingles deteriorate, the roof underlay becomes exposed and will continue to incur significant damages until they are replaced.

Damaged roof shingles can lead to extensive damages that require excessive repairs Damaged roofing shingles may need to be replaced, or you may need an entirely new roof if the damages are extensive.


Florida’s heat and humidity, along with the effects of hurricanes and frequent thunderstorms, are hard on shingles, making it even more important to keep a close eye on your roof for damage. Often this damage comes in the form of curling or buckling which can signal major issues with your roof. Both curling and buckling are most often caused by moisture of your roof decking or underlayment.


  • Buckling shingles appear as if they are being pushed upward from beneath. It can be the result of a lack of insulation or poor attic ventilation, as well as improper installation. 
  • Curling shingles have turned up edges, making the central part of the shingle look like it is sinking (a concave shape). Curling is common, and like buckling, negatively affects the appearance of your roof. The causes of curling can be poor quality materials or normal wear and tear. 


While you can identify either issue looking at your roof from the ground, at the first sign of buckling and curling shingles, you should call your trusted roofing professionals, like the experts at The Roof Guys, for an inspection. 

The Most Common Causes of Buckling and Curling Explained

Shingles Curling - The Roof Guys Florida

  • Moisture – Moisture is the most common cause of buckling and curling. It can be the result of moisture absorbed in the roof decking during the roof replacement process prior to the installation of your new roof. Unwanted moisture can cause the decking to shift and the shingles to buckle. Buckling may also be the result of the absorption of moisture by the felt underlayment which, in turn, causes it wrinkle pushing the shingles up. What causes the moisture in the first place? Many times, the moisture is caused by poor attic ventilation. Florida’s heat and humidity are the culprits. Without proper attic ventilation, that hot, moist air is trapped in the attic causing condensation which can make your shingle buckle or curl. Of course, this lack of airflow and subsequent backup of moisture can allow mold to thrive in your attic and rot your roof deck. Plus, in the hottest months of the year, your poorly ventilated attic makes your air conditioner work even harder, causing excess wear and tear on your unit while your utility bill increases exponentially. And if that isn’t enough, the buckling and curling caused by inadequate attic ventilation will make your roof wear out more quickly than it should, allowing high winds, hail, and storms to further damage your roof.
  • Improper Installation – Another common cause of roof buckling or curling is improper installation of your shingles. When the roof installer fails to use enough nails per shingle or places the nails incorrectly, the shingles can loosen, pulling up from the roof and resulting in curling or buckling. Another reason behind buckling or curling occurs when the tar lines (adhesive strips on the individual shingles) are not properly aligned and are unable to adhere correctly. When this happens during installation, the shingles may even begin to fall off. 
  • Multiple Layers of Roofing – Sometimes homeowners opt to install a new, second roof, atop the current, older roof. While not typically recommended by professional roofers, it is a cost saving measure for homeowners in which the new roof is placed directly over the old roof rather than removing the old roof and installing all new materials. As a result, the second layer of shingles are less secure, and curling and buckling may occur. This second layer is more susceptible to damage by storms and strong winds.  

Roof Damage Prevention 

There are several things that Florida home and business owners can do to ensure that their roofing lasts for many years. Heed the following preventative tips to expand the lifespan of your roof significantly.

Clear Debris After a Storm

Check the condition of your roof and clear all twigs, leaves, and broken shingles after any major storm. Contact a professional roofing contractor to perform these services.

Seek Regular Roofing Inspections

Protect your roof with regular roof inspections. Roofing inspections certify the condition of a roof before you buy or sell your home. These inspections are also an essential part of maintaining a valid homeowners insurance policy.

Invest in Certified Roofing Repairs

Never attempt to cut costs by hiring the services of an amateur roofing contractor. Protect your property by contacting a professional roofing contractor anytime that damages occur.

Replace your Roof When Necessary

Roofing shingles do have a limited lifespan. Regular asphalt shingles are only expected to last for 15 to 20 years. High-end metal shingles, such as copper, offer the longest lifespan by providing property protection for over a century.
