Ten Most Common Commercial Roof Problems to Contend With
Sep 01, 2025Different alternatives for roofing a commercial building would also depend on the type of material and products to be used. Unlike a typical house, commercial roofs will occasionally experience problems that are not entirely immune to certain issues. This means that you may have to read further to know some of the more unusual, rather than common commercial roof problems that you usually face.

10 Common Commercial Roof Problems
We want to ensure that most commercial property owners are aware of some of the most common roof issues. With this knowledge, the owner will be able to make better decisions with contractors, determine what to search for in terms of problems, and develop a maintenance plan.
Below are the ten most common commercial roof problems to contend with.
1. Installation Problems
Installation problems remain the worst issue every commercial roof encounters. Often, the cause of this problem is an inexperienced contractor working on installing the roof, and the property owner’s savings on installation later pay dearly for it.
Usually, the signs of a bad installation would not appear in the early phase, but when the primary effect passes, they would crop up. The common signs are leaks, poorly joined seams, and flashings. An unsecured piece of a roof might also blow off.
Poorly considered roof jobs by inexperienced contractors end up with inferior materials for the job. Those membranes, adhesives, and flashings don’t last nearly as long as materials of high standard.
2. Leaks & Water Damage
Damage due to water and leakage is very common in commercial roofs, something that everybody thinks about first. Leaks can really be troublesome, difficult to locate, and very expensive to fix.
Detecting leaks in flat roofs can be a difficult task, as their damage usually has a considerable cost when found. Checks become important to foresee future problems and stop costly repairs. Among the discoveries during maintenance roof inspection, whenever the property owner discovers an issue, there is still a chance of addressing it.
3. Surface Erosion & Punctures
Roofing membranes, when new, are quite durable and tough, but with time, will deplete, wear, and exhibit thinning under high-traffic areas – typically from maintenance workers or HVAC technicians going up to work on rooftop equipment. These areas get worse until they tear or puncture and leading to leaks and further damage.
This can be tricky. Regular inspections of the roof should be made mandatory to catch problems at inception. More walking on the roofing membranes translates into a greater risk for surface erosion. The added layer of membrane by these roofing experts could cover that surface for foot traffic. Erosion is decreased as long as the building staff know to stick with these paths.
4. Dummy Water
A seam in the roof membrane may be lengthened and stressed when water collected over it, or ponded, remains on it for too long, causing degradation of the material, with possible leaks. The rooftop ponds serve as a great breeding ground for mold and algae, making the walking surface hazardous.

5. Shrinkage in the Roof
No roofing membrane remains unaffected as it undergoes shrinkage through time; of these materials most easily assimilated shrinkage is by EPDM (ethylenepropylenediene monomer), which is installed without any stretch. It is, in fact, the first to age and actually lose flexible properties due to the exposure to severely destructive UV rays at the molecular structure, and shrinkage, therefore, occurs. Shrinkage is also one of the common commercial roof problems that building owners face. However, both TPO and PVC roof materials do get affected.
Shrinkage sometimes leads to the membrane pulling apart from flashing and the separation of seams. Leaks in the roof are also due to the cracks and tears caused by shrinkage. Routine checks would discover signs of shrinkage and roof coatings or repairs that would enhance the lifespan of the commercial roofing.
6. Flashing Fails
The flashing plays an important role in the roof support of the roof membrane. They seal around edges to not only help prevent water intrusion but also guide away from the seams and chimney, wall, or penetrations.
Generally, a roof’s flashing would fail or cause a leak due to aged flashing or improper installation, or other work done on the roof. In fact, flashing is, in most cases, easier to remove than patch or repair.
7. UV Rays
Simply put, it is the Ultraviolet rays of the sun that wear down the material, making it snap and erode. Therefore, damage occurs in terms of perforations and erosions.
UV damage is probably one of the most common commercial roof problems and breakdowns, but most will not become obvious until the roof surface has aged. Meanwhile, a homeowner cannot avoid or control UV exposure. However, an experienced contractor will help guide a homeowner on which materials will work best for them.
8. Heat Blistering, Bubbling
Bubbles and blisters on roofs are not a good sign. Bubbles under the roof membrane, moisture trapped between the membrane and the deck, will not permit proper adhesion.
Blisters and bubbles do several things. For example, they can grow and spread. The damaging effect often erodes the fabric and produces thin patches, punctures, and tears. These are instances of damage often seen where leaks or poor installation occur. Before they create any costly damage, these issues will need to be addressed.
9. Destroyed or Blocked Drains and Gutters
Gutters, downspouts, and drains are extremely crucial in their performance on the roofs. Hence, every opening must be clear of blockages. As soon as anything blocks this throughput, whether it be a few pieces of debris or even a nesting site for birds, the water will not flow off the roof as efficiently, thus creating an ice dam.
Clean your gutters regularly. Take a walk on the roof – look at the drains; do the shoveling to remove marks of debris.
10. Poor Maintenance and Repair
So often, maintenance and repair become the key issues that trouble commercial roofs. Without regular maintenance regularly including at least inspections, small repairs, and maybe the nod of a professional, roof surfaces will fail prematurely. Roof materials, even if strong, just need maintenance to survive, especially when addressing common commercial roof problems.
