Why is My Roof Buckling?

Have you ever seen a roof that appears to be lifting in certain areas? This is called "buckling" and not only does it distract from the beauty of the home, but it can lead to other major roofing problems. Today's blog from your Lake of the Ozarks roofer discusses buckling roofs, what causes them and what can happen if they aren't addressed.

What Causes a Buckling Roof 

When your roof is buckling, it resembles a large air bubble that stretches the roof sheathing, felt and shingles. This can be caused by a variety of different circumstances:
  1. Improper Installation of Felt or Underlayment - Buckling can occur when the felt or underlayment is not installed properly. If these products are wrinkled, it can easily show through the roof shingles, as the shingles are installed over it. 
  2. Movement in the Roof Deck - The roof decking is the plywood sheets that cover your home, under the shingles. If these boards are not installed properly, with spacers, they can shift and cause the roof to buckle. The spacers are needed to absorb any expansion from excessive heat. Deck movement can also occur when water finds it's way under the shingles due to a leak. This can cause the decking to swell and warp, and eventually rot. This can lead to serious damage to your home. 
  3. Poor Roof Ventilation - In the event your roof is not properly ventilated, moisture will collect in the attic. This moisture becomes condensation on the underside of the roof, which can cause damage to the home's frame and roof decking. When that moisture gets trapped between the underlayment and the shingles, buckling can occur. 
  4. Failure to Remove Old Shingles - Applying a new roof over an existing one can also lead to a roof buckle. In this case, it's much harder to get the new roof applied properly to prevent moisture between the layers. You can almost guarantee that you'll eventually have buckling problems when you fail to remove the old shingles before installing a new roof. 

Future Problems of a Buckling Roof 

If you notice a buckle in your roof, you'll want to schedule a Lake of the Ozarks roof inspection, as that buckle could be a sign of worse problems or future problems to come. Not only can moisture damage the roof from the inside out, but that buckle could create entryways for water from outside to enter your home. Roof leaks and interior water damage could end up being a result of a roof buckle left unaddressed.
