Approximately 80 percent of roofing companies have realized a 10 percent increase in labor costs in recent times. Considering that labor costs are among the specific areas that cut into profits in most industries, especially those that can’t automate their solutions, they’re a major reason behind roofing services being so expensive. With this in mind, it’d be wise for any business owner to understand the various commercial roofing issues that could prompt them to request roofing services.

Roofing issues can occur due to wide-ranging factors, including punctures and penetrative actions as well as leaks and wind issues. Read on to find out more on the issues that compromise the lifespan of roofing systems.


All roofing systems are vulnerable to expansion and contraction when exposed to varying temperatures. This is particularly true in the case of single-ply roofing structures, which are quite popular in commercial establishments. Shrinking often affects the roof membrane located under the roof shingles. Once the membrane begins to contract, it may cause the roofing’s upper layer to crack and craze. Thereafter, the shingles, as well as the entire roofing structure, may become dysfunctional such that the shingles may no longer be able to shed water. This ends up reducing their lifespan.

You can confirm shrinkage issues if you notice that the flashing could be gradually pulling away from the wall. When prompt action fails to be taken, the problem may lead to more significant issues, including leaks, structural warping, and broken joints, leading to financially taxing repairs or replacements.

Inadequate Waterproofing

Roofing structures play a vital role in protecting your investments by preventing excessive water filtration in your local business. Commercial roofing installation experts use roof flashings made of rust-resistant galvanized steel, copper, and aluminum as well as rubber and plastic as the preferred waterproofing materials. They’re placed at the ending points and on the intersections of the roof since they seal the gaps, thereby preventing water infiltration. You can easily identify the flashings near the vent pipes, skylights, or roof ridges.

Experts in the servicing of commercial and residential roofing structures often attribute damaged flashings to weather action. Nonetheless, professional roofing technicians can help inspect and replace the damaged flashings to ensure minimum water entry.

Roof Expansion

As previously stated, roofing systems may expand or contract when exposed to hot or cold temperatures respectively. After all, fundamental scientific principles support that atoms expand when heated and they cool if they come into contact with low temperatures. In that regard, the roof along with the protective materials therein comprise atoms that are not exempt from the above-described phenomenon. However, the effects of the heating and cooling action may become worse when there’s a rapid temperature fluctuation. Your business’ roofing system may begin to physically deteriorate as cracks start to form with every temperature change.

If it comprises metal flashings, the flashing may also suffer significant damage, which can have devastating consequences on your San Antonio, TX business. Most notably though, synthetic rubber coverings may suffer the most damage since they expand and contract relatively easily. Under such circumstances, you should consult with a professional roofing contractor to find the most appropriate preventive maintenance solution to help you steer clear of roof expansion issues. That way, you can avert financial cutbacks that may arise when your business closes temporarily due to commercial roofing issues.

Accumulating Water

Flat commercial roofing structures are quite common in the majority of business establishments. If improperly installed, the surface may end up being uneven. The dents and slopes therein may then inhibit the proper flow of water, resulting in rainwater gradually pooling on top of the roof. Experts in commercial roofing installation and servicing strongly advise against letting water pool on the building’s roof even for as little as 48 hours. They advise that the longer water stays stagnant on the structure the more likely the property owner is to encounter more serious consequences, including exposure to health risks. For instance, considering that an inch-deep of water approximately weighs 5.2 pounds per square foot, water accumulation may add significant weight to the system, causing its structural integrity to gradually deteriorate.

If left unresolved, the additional weight may significantly damage the various commercial roof layers and in some extreme cases, lead to roof collapse, which can not only cost lives but also insurmountable financial losses. Aside from uneven roofing systems, water accumulation may result from roof drainage blockages. However, regardless of the cause, professional roofing contractors can help remedy the situation by tapering the surface to ensure it’s even or inspecting and removing clogs from drains.

HVAC Issues

Commercial buildings have extensive heating and cooling needs and that’s why they’re fitted with sizable heating, ventilation, and air conditioning systems to ensure their occupants remain comfortable during their productive hours. Most of the heavy components are placed on the building’s roof. While this helps protect the valuable investment, it may lead to the destruction of the equally valuable commercial roofing system. Leaks that may develop in the heating and cooling system could greatly compromise the integrity of the roofing structure beneath the units. This is because the structure may grow weak over time and eventually give way due to the immense weight of the commercial HVAC system.

Consequently, you’re bound to incur significant losses should the roof collapse after failing to address such matters on time. The notably effective way of avoiding such sticky situations is by embracing regular commercial roofing maintenance. Professional roofing contracting technicians recommend a comprehensive inspection and maintenance service twice annually. They also discourage DIY roofing maintenance as you may lack the training to identify the underlying problems as well as the tools and knowledge needed to remedy the situation.

Improper Installation and Repair

Sometimes commercial roofs may fail to withstand the test of time because of poor workmanship or substandard installation work. While most contractors strive to provide professional roofing contracting services, some may lack the expertise or training to handle complex commercial roofing projects, forcing them to cut corners during the service. For instance, built-up roofing membranes comprise several layers whose materials should be cleaned, dried, and primed for the conjoining adhesive to work properly. Any mishap on the side of the installer may cause the adhesive to come off. That’s just one of the many reasons why you should always pick a reliable installation company for all your commercial projects.
