About Me

Would You Be a Roofer? Some people work as roofers for a summer or two. Others become lifelong devotees to the profession. Those who commit to roofing as a long-time profession really take the time to learn the details. Not only do they learn how to put roofs in place, but they also learn quite a lot about various roofing materials. This equips them to make good recommendations to homeowners who are looking for the right roof. We will also make some recommendations and tell you a bit more about roofers on this blog. While we are not roofers ourselves, we know a lot about the profession and are always happy to share.





Uplift occurs when asphalt shingles are no longer laying flat along the surface of the roof. Knowing the causes of uplift is important, as well as taking prompt repair steps to avoid damage.


The most common reason shingles will lift on a roof is due to the wind. If a strong wind hits the roof at the right angle, it can ruffle the shingles almost like feathers. Although shingles are designed to lay back down if ruffled, in some cases they may be damaged so that they remain uplifted.

Other issues can also lead to uplift. In the winter, the formation of an ice dam from blocked gutters means water gets beneath the shingle and freezes. This lifts the shingle up. Moss on the roof can also grow beneath the edge of a shingle and lift it. Age can also lead to uplift, as deteriorating shingles begin to curl at the edges. 


Uplifted shingles are more than an appearance problem. Once a shingle is uplifted the waterproof membrane of the roof is broken. Dew, condensation, and rain can all run under the shingles and leak into the home. Prolonged water exposure from uplift will eventually cause the roof sheathing panels to develop rot as well.

Even if the shingle isn't damaged, it will eventually develop problems if it isn't repaired. Creases and cracks can form on the shingle, for example. Further, the constant moisture exposure on the underside of the shingle may also lead to deterioration of both the uplifted shingle and those that are neighboring it. What begins as a single damaged shingle can quickly become several damaged shingles.

Repair Options

Repair options depend on the extent of the damage. If the shingles are ruffled up but not creased or torn, your roofer may be able to flatten them and add some adhesive to help prevent future uplift. If damage is minimal, then only those shingles that have torn or creased need to be replaced.

In the case of water damage beneath the shingles, you may need to have any water-damaged sheathing panels removed and replaced so the rot doesn't spread. Then the shingles on top of the damaged sheathing must also be replaced. If curling and damage from uplifted shingles are extensive, it may make more sense to simply replace the entire roof.

Contact a roof repair service if you suspect that uplift damage is a problem on your roof. A roof repair service can provide additional information.
