Single-ply roofing membranes are the best for both standard and effective roofing systems in terms of cost and durability. However, as with any other system, even the best ones have their issues. A primary problem that residential and commercial building owners usually deal with is the formation of air pockets in single ply roofing membranes. Even though these bubbles may seem manageable initially, if they are not caught in time, they can create considerable problems.
These so-called ‘voids’ do not seem to pose any threat but rather appear to be decorative and, quote on quote, ‘excuse’ the pitying quality of the appearance; they cause trouble as they dangerously reduce the waterproofing effectiveness of the roof. Prior knowledge and understanding of what these breaks are and, more importantly, their causes go a long way in tackling the problem of these voids; once you understand their cause, the keys to maintaining a sound roof that braves the weather are in your hands. Air pockets in single-ply roof systems are a real threat to single-ply roofs; here is an article that provides information on how to avoid them.
Understanding Single Ply Roofing
Single-ply membrane roofing has gained popularity with those who have both commercial and residential buildings. These single-ply membranes are made of synthetic material, which is light but strong and thus easy to install.
The main types include TPO (Thermoplastic Olefin), PVC (Polyvinyl Chloride), and EPDM (Ethylene Propylene Diene Monomer). Each membrane type has different advantages to suit diverse climates and building requirements.
Among the benefits of single ply roofing is the high level of flexibility. Different shapes and sizes can be covered, which helps with the installation process. This minimizes potential weak points where water could easily get through.
In addition, single-ply roofs are very efficient in terms of energy consumption. Heat absorption is limited by many reflective products, making the cooling costs considerably lower during the hot months. As long as they are maintained properly, these roofs are not affected by elements for a long period.
Causes of Air Pockets in Single Ply

Several issues can cause air pockets beneath single ply membranes. One problem is that the membrane needs to be installed better. If the membrane is improperly fastened, it creates a risk for air pockets to form.
Besides that, temperature changes are another cause. When heat and cold set in, the materials under the membrane move, creating more room for air pockets.
Moisture intrusion also plays a significant role. Whenever water flows to the membrane, it breaks constituent material from adherence and enters into air-filled blisters.
Moreover, poorly draining flat roofs can also worsen this problem. Water vapor mildewed in the roof surface increases pressure, forcing air through any weak points.
Scheduling routine inspections and maintenance is critical to prevent problems from becoming severe, including roof membrane damage through the creation of leaks.
The Potential Risks of Ignoring Air Pockets
Not bothering about air pockets within architectural structures that utilize single ply roofing is like volunteering to make things more difficult for oneself in the future. Air trapped in these voids is an inherent weakness and actively works against the entire finish of your roof.
If allowed to prevail, these flaws, after a certain time frame, can allow moisture to seep through, thus resulting in all sorts of traditional building malfunctions, most notably the emergence of mold and damage to the structure. This, in turn, further worsens the roof’s structural integrity in the short and long run and increases the health risks among the occupants because of the poor air quality.
Pockets of air may also increase thermal inefficiencies whenever possible. Air pockets undermine the overall insulation performance, raise energy bills, and cause discomfort due to the non-ideal temperatures experienced in the indoor environment.
Furthermore, if they are neglected and gotten around to later on, the repair bills can accumulate like there’s no tomorrow. What would have otherwise been an easy fix today might become many repairs, forcing you to shell out big bucks or replace the roof later.
Air pockets must be dealt with on time, or property owners will be stuck with expensive, unpleasant, and unpleasant headaches. Conducting proper audits is a good practice in promoting the smooth functioning of the enterprise in the future.
How to Identify and Locate Air Pockets
Identifying low spots or air pockets in single ply roofing membranes is relatively simple, but one needs to know what to look for; first, you must perform a visual inspection. Look for blisters or protrusions; these might indicate that air has been trapped below the membrane.
After this, run your hands over the membrane and look for soft spots. Such areas may suggest that the membrane has started delaminating with the substrate.
If you feel comfortable doing so, lightly push down on the areas you suspect. A negative sound may suggest an air pocket is found beneath that section.
As a more sophisticated method, consider using infrared thermography scanning. This technology is based on detecting temperature differences and can pinpoint air areas hiding underneath membranes that didn’t appear in routine surveying. Spotting such problems in time helps to protect the integrity of your roofing system and increases its durability.
Repairing and Preventing Air Pockets in Single Ply
Caution is needed when addressing air pockets in a single ply roofing system. Begin with a proper evaluation of the extent of the damage. The other details to consider include spotting any loose seams or potential bubbles that may have formed due to the air trapped.
After this, locate the pocket and employ the utility knife to make an X cut over it. This causes trapped air bubbles to be released as drainage occurs, making it easy to deal with any headaches associated with the air bubbles. Once you’ve removed the force, polish the adhesive below the covering to eliminate rough edges.
Prevention is just as important. A good number of leaks can be avoided by carrying out regular inspections to check problems before they turn into other larger problems. Ensure that the guidelines are followed from the initial stage, as this will reduce the chances of air pockets forming in the future.
Also, consider getting quality materials that are more suited to your local weather. The right choice can significantly lessen probable weaknesses in your roofing system in the long run.
Hiring a Professional for Repairs and Maintenance
A professional should repair air pockets in single-ply roofing. These people are equipped with the appropriate knowledge and tools required to assess problems that an ordinary person may not be able to see.
Roofers have mastered roofing systems, roofing materials, and installing roofs. Such experience enables them, on most occasions, to determine the cause of air pockets and so concentrate on that for a quicker and more efficient repair procedure.
Furthermore, hiring professional technicians can save you considerable money and time. Also, they can educate you about maintaining your roofing system in a way that will avert such problems in the future.
Employing professional staff also ensures safety while carrying out the repair works on your roof system. Roof activities can be risky without the required knowledge and proper tools; professionals are trained to counter such risks. So that your roof is worked on with expertise, you are assured of quality and peace of mind.
Conclusion: Maintaining Your Single Ply Roof for Optimal Performance
Taking care of your single-ply roof is important. If you want it to last long, remember its function. It will be better in the long run to do regular inspections to avoid repairs that would otherwise be very expensive. Be sure to act before a problem multiplies; have a routine where you constantly look for damages, and if there are any, try to resolve them quickly.
Engage roofing companies familiar with single-ply membranes in formulating a maintenance program. This will eventually save you time, funds, and much effort.
Every single-ply roof undergoing pockets of air must be addressed uniformly. At first sight of the problem, remedial steps must be evaluated to prevent further aggravating the situation. Put, provide roofing protection today to protect your building tomorrow.
