Flat Roof Maintenance Needs for Cape May County Strip Malls and Retail Plazas

Whether you’re a tenant or a property manager of a strip mall or retail plaza in Cape May County, one thing remains true: You need to keep a roof over business. Even a slight leak can cause revenue disruption from a decrease in valuable foot traffic. Flat roofs, which are common for strip malls and retail plazas, require maintenance, just like residential roofs. With proximity to the coast and marshlands, commercial properties throughout Cape May County need even more flat roof maintenance, due to the salt and humidity.

So what does flat roof maintenance entail? How often should it be scheduled? Let’s get right to it.

Why Flat Roofs Are Common in Strip Malls and Retail Plazas

Flat roofs cover a vast majority of strip malls and retail plazas throughout the United States. There are certain reasons for that. First, there’s a design advantage. A flat roof means that HVAC units can be placed on top of the roof, maximizing parking lot and warehouse space. Utility routing is simplified. Flat roofs are also cost-effective, particularly when the footprint of a building or structure is larger than a residential building.

Of course, the advantages are matched with some vulnerabilities. Flat and low-slope roofs have limited drainage, meaning that membranes and roof coatings need special waterproofing to ensure moisture doesn’t seep in. Even with specialized drainage, there is always a risk for standing or ponding water.

Coastal and Commercial Stressors That Accelerate Flat Roof Wear

While flat roofing is designed to be resilient, there are certain stressors that cause it to age more quickly along the coastline. In Cape May County, the air is more humid and filled with salt when compared to other areas of South Jersey that are further inland. The salt particles settle on roofs and may cause certain types of metal to corrode. Commonly, fasteners and flashing on older buildings start to deteriorate, leaving tiny openings for water to breach.

Coastal commercial roofing also faces more dramatic temperature fluctuations. UV exposure paired with high temperatures in the summer are matched with cool nights and, later, frost. These intervals of hot and cold increase the risk of seam separation as materials expand and contract with the ambient temperature.

Lastly, the very crews that access your roof for maintenance on HVAC equipment, for example, may cause damage. Foot traffic and impacts from dropped tools can cause compression damage and membrane punctures.

Common Flat Roof Problems in Retail Plazas

Now that you know more about flat roofs and their stressors, let’s discuss some common problems that occur:

• Ponding water: Caused by backed up drainage or improperly placed drains, as well as soft spots. Ponding water can cause long-term membrane damage, leading up to a premature roof replacement.
• Seam and flashing failure: Found along rooftop penetrations and parapet walls, seams and flashings are susceptible to loosening (due to hardware corrosion) and letting in water.
• Drainage system failure: Clogged scuppers and internal drains may cause water to back up and pond on the roof, where the roofing materials will begin to degrade due to excessive moisture.
• Membrane punctures: Often a result of equipment servicing damage, membrane punctures can lead to water intrusion and leaks.

Seasonal Flat Roof Maintenance Requirements

What must be done during flat roof maintenance to ensure that strip mall and retail plaza buildings are properly protected? Each season has different things that should be checked to ensure damage is appropriately assessed.

• Spring: As temperatures begin to rise again, it’s important to bring in a professional roof inspector for a freeze-thaw damage assessment. Finding places where seams separated or flashing loosened due to ice will prevent leaks later.
• Summer: UV degradation and sealant drying can lead to bubbling, blistering, and seam separation. Roof maintenance during this time should focus on enhancing UV reflectivity.
• Fall: While most strip malls don’t have many trees, there is a chance of leaf accumulation causing blocked drainage. During the fall, heavy rainfall is also possible. Be sure to get the gutters or scuppers cleaned.
• Winter: Snow load concerns are the biggest issue, as well as ice buildup around drains and penetrations.

How Maintenance Protects Property Owners and Tenants

Roof maintenance is an essential task that keeps more than a roof over everyone’s head. When the roof is functioning properly across every single business, disruptions are minimized. There is a reduced risk of interior damages, like a severe leak, causing damage to merchandise. Lease disputes caused by water intrusion may also arise if the roof isn’t functioning correctly—and that is a headache for all involved.

Liability and insurance considerations need to also be addressed. When there is a chance of slipping because of leaks, any personal injury that follows will fall upon the property manager.

At the end of the day, maintenance preserves your investment, as well as the relationship you have with the many tenants within the plaza or mall. It’s much more cost effective to maintain a roof than need to repair or replace it prematurely.

Signs Retail Property Managers Should Schedule Immediate Service

How do you know when to call a commercial roofing contractor in Cape May County? There are several signs that tell you something is wrong:

• Multiple tenants (or the same tenant) repeatedly complain about leaks
• Interior ceiling staining in various stores
• Noticeable ponding on the roof after rainfall that lingers for more than 36-48 hours
• Increased HVAC vibration damage

Schedule Your Commercial Flat Roof Maintenance Inspection

Flat roof maintenance is a crucial part of keeping a strip mall or retail plaza in Cape May County up and running. Furthermore, when you maintain instead of repair, you can save money and prolong the lifespan of your roof. Tenants also gain peace of mind knowing that their store is safe from the elements.
