Although the lifespan of flat commercial roofing systems may depend on the material used to construct them, they should adequately protect your Austin, TX, business for 10 to 40 years. However, this doesn’t imply that the system won’t fall victim to various common problems. While roofing replacements may comprise over 90 percent of the roofing market value and size, you can avoid them by understanding some of the common roofing problems business owners often encounter.

By having a working knowledge of these issues beforehand, you can pursue the appropriate solutions before your business needs a full-scale roofing replacement, which can be quite expensive. Below are some of the common problems your commercial roofing contractor can help diagnose and fix on time. These are influenced by variables such as product quality, roof use or abuse, and weather patterns.

Poor Waterproofing

The key function of your business’s roofing is to prevent water infiltration, thereby protecting your investment. During installation, your roofing technician may use rust-resistant flashings made of rubber or plastic as well as galvanized steel, aluminum, and copper to waterproof the structure. They mostly mount the flashings at the peripheral points of the roof or near roof intersections to seal any gaps to guarantee no moisture infiltration.

You can ask your preferred contractor to show you where they’ve been placed, but they can be easily spotted near roof ridges, skylights, and vent pipes. In most cases, inclement weather is to blame for damaged flashings.

Despite that, a well-trained commercial roofing technician can help inspect and fix or replace the damaged flashings to guarantee minimum water intrusion and long-term service.


Regardless of whether your property has residential or commercial roofing, all systems may expand or contract depending on the external temperatures. These actions may be more prominent in single-ply roofing membranes or metallic roofing systems. When shrinkage occurs, it usually affects the roofing membrane, which roofing contractors place beneath the shingles.

As the membrane contracts, the upper layer may begin to crack and craze, which in turn may cause the roofing structure to significantly lose its efficiency. In this regard, it becomes really difficult for it to get rid of run-off water, a scenario that decreases its lifespan.

Shrinkage issues are often denoted by the flashings beginning to pull away from the intersecting points such as walls. When left unresolved for a long time, shrinkage problems can result in structural warping, massive roof leaks, and broken joints. Be warned that the resulting repairs or replacements can be financially devastating to any Austin, TX, business owner.

Water Accumulation

Most commercial roofing structures are flat or low-sloped. However, this doesn’t warrant the accumulation of small, or in extreme situations, large ponds of water on them. Flat or low-sloped commercial roofs can begin accumulating water if the installation contractor performed shoddy installation work.

Therefore, they may have failed to incorporate an adequate slope, limiting the movement of rainwater and water from commercial heating and air conditioning systems into the drains. Another reason why moisture may start accumulating on commercial roofs is due to birds building their nests on roofs and near drainage outlets. Sometimes water may collect due to the consistent buildup of leaves and debris on the roof.

As the water continues to collect, it may seep into the cracks, thereby increasing the rate of thermal expansion, and causing the roof’s structural elements to rot. To avoid such scenarios, you should contact a trusted roofing contractor for regular roofing inspections and cleanups.

Roof Expansion

As predetermined earlier, heat or cold may cause roofing structures to expand or contract. However, the rate of expansion or contraction may change drastically when there are severe or rapid temperature fluctuations. With time, the commercial roofing system of your business may begin cracking each time there’s a significant temperature change. This may be particularly worse if the roofing structure features metal flashings.

Besides, if your building’s roofing is made of synthetic rubber, the impact of roof expansion may be much stronger since synthetic rubber expands and contracts relatively faster compared to other roofing materials. A reliable roofing technician can help find impactful preventative maintenance solutions for roof expansion problems that may lead to your business closing down, leading to major financial losses in the process.

HVAC Problems

Commercial establishments have significant heating and air conditioning needs that require the property owner to invest in an HVAC system that’s large enough to serve everyone’s heating and cooling needs. Besides keeping people comfortable, most businesses utilize heating and air conditioning systems to cool energy-intensive equipment that may generate substantial amounts of heat when in use.

Due to the large size of commercial HVAC equipment, they’re often heavy and have to be placed on the roof since in most cases it could be the only place with ample space. Although placing it on the roof can help protect it from damage, your actions may soon have a ripple effect on your building’s equally important commercial roofing. In that case, the structure may start weakening due to the HVAC unit’s heavyweight.

Therefore, failing to address the issue on time may leave you vulnerable to significant financial losses if the roofing collapses due to the immense pressure. On the bright side, regular roofing maintenance at least twice annually can help avoid such disastrous situations.

Tree Damage

If by any chance a tree plummets through your building’s roofing structure, then you could be in deep trouble. Additionally, even tree branches constantly rubbing on the roof surface can cause the structure to wear out with time. Ideally, it’s better when your building’s roofing has no branches resting over it, which is why regular tree trimming should be a priority within your property if you want to safeguard the integrity of its roofing. You should also not be afraid to request a tree removal service for those that can cause significant damage to your roofing.
