How to Fix Buckled Roof Shingles?

A well-structured roof of a building protects you and your possessions from the invasion of damaging foreign elements, such as accumulation of rainwater or melting snow whose moisture may start trickling down from shingles to reaching the interior ceilings and adjacent walls of the house, compelling you to learn how to fix buckled roof shingles.

Buckled roof shingles are not defects in the shingles, but the root cause is unevenness or wrinkling of the underlayment or distorted movements in the wooden decks. Typically, a roof should look smooth and in good condition. However, ripples or waves in the roofing surface confirm that the decking or shingles are probably buckled.

Causes of Buckled Roof

Before diving into how to fix buckled roof shingles, it is crucial to know its root cause and why the shingles buckle in the first place so it would become easier to implement the efficient solution.

The following are the leading causes of a bumpy roof due to wrinkled shingles:

Heat Exposure

Prolonged exposure to the sun's scorching heat can either expand or shrink the shingles, leading to buckling. Or if you've recently had a roof replacement, you'll notice that when the old roof is removed, the deck may absorb moisture content of the environment, which is another common reason to understand the depths of how to fix buckled roof shingles.

In addition, if you neglect the utilization of spacers between the decking, expansion and contraction can quickly occur. Therefore, Built up roofing experts recommend the placement of spacers because they are efficient enough to absorb excessive heat.

Moisture Accumulation

The adhesive bond between the shingles is weakened due to water accumulation, resulting in the shingles' lifting and buckling. The decking is also continuously damaged by continuous exposure to moisture, which deteriorates the architectural health of your home.

Poor Installation Process

The root cause of wrinkled or curled-up shingles is improper underlayment installation upon which singles are placed in a symmetrical pattern.


Regardless of the durability and increased age span of the type of roof installed in your residential or commercial properties, the shingles may become bumpy or rough over time because of prolonged exposure to heat and moisture for decades. With age, the likelihood of even the most vital roofing process gets susceptible to wrinkling or buckling.

Attic Remodeling

Water accumulation is highest after the interior remodeling of the attic. Inadequate ventilation and wet processes with drywall and plastering make the roof tiles curled or wrinkled.

Inadequate Sheathing

An appropriate spacing of at least 3 millimeters is necessary between roof sheathing. If this distance isn't maintained, buckling occurs due to expansion and contraction.

Excessive Insulation

The ventilation system is compromised when homes are constructed tighter and possess increased insulation levels, which could be another ultimate cause of buckled shingles.

How to Fix Buckled Roof Shingles

Now you are aware of the root causes, let's go through the following steps to understand how to fix buckled roof shingles like a pro:

Precautionary Measures

Before starting the job, you must equip yourself with all necessary precautions to stay safe throughout the project. For instance, safety harnesses and ropes prevent falls, and slip-resistant shoes maintain your traction on the roof. In addition, gloves and eye covers protect your hands and eyes from debris, while a balanced ladder certifies the accuracy of a sturdy position.

Damage Inspection

Evaluate the extent of damage before fixing the buckled shingles. Investigating your entire roof reveals the distorted sections by identifying all the weakened areas that must be addressed promptly. In addition, it is also essential to compensate for missing or curled-up shingles.

Materials and Equipment

You need to get hands-on training before trying how to fix buckled roof shingles, such as cement, a utility knife for precise cutting, and nails and hammer to reattach shingles. Besides, roofing adhesives are also utilized for additional support.

Smoothen the Buckled Shingles

After carefully assessing the roof, its underlayment, and decking, it is essential to maintain the overall appearance of your home's roof.

Gently lifting the distorted shingle and applying an even layer of roofing cement beneath it effortlessly balances and evens the look. Press the shingle down for some time to allow the adhesive bond to work.

The shingles are fixed in their appropriate position near the edges with roofing nails, ensuring a firm positioning. Be cautious not to overdrive the nails as it could distort the shingle. In addition, applying small fractions of adhesives over the pins acts as a sealant to create an extra layer of protection.

Final Wrap Up

Learning how to fix buckled roof shingles prevents further wrinkling by replacing the damaged sections with new ones, which must be protected by regularly inspecting the entire roofing system. Moreover, a well-ventilated attic regulates the temperature by expelling excess heat and welcoming fresh air inside the house.
