5 Common Issues with Flat Roofs

A commercial flat roof is a common sight on buildings of all shapes and sizes.

While they offer many benefits, they also present unique challenges that building owners and property managers must address to ensure their long-term performance and protect the building owner's investment.

Flat roofs have several benefits when installed on commercial buildings.

Their design makes them ideal for placing equipment to keep commercial buildings running smoothly—bulky items such as telecommunications and HVAC components. Flat roofs are also more cost-effective and can be installed more efficiently.

That said, commercial flat roofs do have their share of issues.

In Hudson Valley, New York, we are presented with a unique set of circumstances that affect flat roofs, such as weather extremes.

In this article, we'll take a look at the top five issues that can affect commercial flat roofs in Saugerties and what you can do to address them.

5 Common Issues with Flat Roofs

Issue #1: Flat roofs are susceptible to leaks

Flat roofs are vulnerable to leaks, which property managers and building owners must keep an eye out for. This is mainly because, without a slope, water has nowhere to go but down and under the membrane.

Roof leaks can appear minor at first, but they can rapidly grow into much bigger problems, leading to property and structural damage, if left unchecked.

Solution: Ensure the roof is properly sealed and waterproofed at all seams and edges. Regularly check for any signs of leakage, and immediately call a commercial roofing contractor for repair. The best way to prevent leaks is by having a regular maintenance schedule in place for your commercial flat roof. This should include inspecting the roof for any damage, repairing tears or holes as soon as they're found, and keeping gutters and drains clear so water can flow off the roof properly.

Issue #2: Flat roofs are susceptible to damage from exposure

All flat roof concerns can be traced back to one thing: exposure

Some roof damage is unavoidable since a structure's roof is continually subjected to weather and environmental situations.

Even if the most durable roofing material is utilized, it will succumb to exposure to the elements and need repair or replacement over time.

When a structure is exposed to the elements, it is prone to various issues due to this exposure.

Sun and heat exposure, lightning strikes, cold temperatures, hail, and wind or debris damage are all potential causes of flat roof damage.

Solution: The best way to protect your commercial flat roof from exposure is by installing a proper roof insulation system. This will help keep the building cooler in summer and warmer in winter, preventing thermal shock that can damage the roofing membrane. You may also consider having a lightning protection system installed in your building. And finally, make sure you have a quality roof coating system in place to protect the roof from UV damage and weathering.

Issue #3: Flat roofs are prone to pooling or ponding water

One common issue with commercial flat roofs is ponding water.

This happens when rain, snow, or ice accumulates on the roof and does not drain properly, often creating a puddle or pond. The water can then leak into the building, causing damage to ceilings, walls, and insulation.

Most flat roofs are slightly sloped and directed toward a drainage system.

However, water, snow, or ice may build up over time, and standing ponds can develop. The weight of the accumulating water may cause the roof to sag, resulting in a leak.

Solution: To prevent this from happening, it is essential to have a well-designed drainage system in place for your commercial flat roof. This should include proper gutters and downspouts that direct the water away from the building. The roof should also be sloped slightly for efficient water runoff. A high-quality, waterproof roofing sealant like Prokol MonoSeal can also help to ensure that your roof has a solid defense against water leaking through and causing further damage.

Issue #4: Flat roofs may experience blistering, holes, and tears

Flat roofs may experience damage from blistering, holes, and tears. This is often the result of exposure to the elements, as mentioned above.

The most common locations for these issues are around protrusions. Areas like around vents or chimneys, at seams and edges, and in the regions that have been patched or repaired in the past are especially susceptible.

Blistering, as well as other surface problems like "alligatoring," can affect flat roofs. Alligatoring refers to a flat roof membrane that has deteriorated to the point that it appears scaly.

Blistering is the formation of bubbles or pouches on the roof surface. Both of these problems result from the roofing membrane being stretched too thin, and they can lead to tears, punctures, and leaks.

Solution: To prevent blistering, punctures, and tears, it is crucial to keep your commercial flat roof in good condition by having it regularly inspected and maintained. It is also important to properly seal and waterproof all seams and edges on your commercial flat roof. A high-quality roof coating system can help protect the roof from further damage. If you detect any of these conditions, fix them immediately to avoid additional damage. A professional roofer should seal any tears or perforations that may form due to the damage.

Issue #5: Flat roofs are susceptible to biological growth

Another common issue with commercial flat roofs is biological growth.

This can be caused by a variety of things, including improper drainage, standing water, and the presence of algae, moss, or lichens.

These organisms need moisture to grow, and they can often damage the roofing membrane or insulation.

Solution: The best way to prevent biological growth is to keep your commercial flat roof in good condition by having it regularly inspected and maintained. You can also use a biocide or fungicide to kill any moss, algae, or lichens that may be present on the roof. With a preventative maintenance schedule, a professional roofer should also clean the roof periodically to remove any built-up dirt, debris, or organic matter that can contribute to the growth of these organisms.

What is TPO Roofing and Why Your Commercial Building Needs It

Many commercial buildings and business owners are turning to TPO roofing as a way to save on energy costs and improve the aesthetics of their properties.

TPO roofing (Thermoplastic Polyolefin) is a low-cost, heat-reflective, and energy-efficient roofing product that has become one of the most popular choices for residential and commercial building flat roofs.

When it comes to TPO roofing, MM Dynamic of Saugerties is the best provider in the region.

Here's how TPO roofing can help you:

What is TPO Roofing Material?

Thermoplastic polyolefin (TPO) is a relatively new roofing material that rose to prominence during the 1990s.

Instead of using multiple layers of roofing membrane as many popular low-slope and flat roofing materials require, TPO is a single-ply solution.

This environmentally-friendly roofing membrane is also heat-welded together for leak resistance. TPO roofs are low maintenance and do not hold dirt or debris.

TPO is among roofers' top choices in commercial building flat roofs because it requires little maintenance and will last 15-20 years with its high tear strength properties. 

TPO roofs are also Teflon-coated, which means that this material is oil and water-resistant.

TPO roofing has also been proven a winner in the commercial market because of its chemical resistance, fire retardant properties, and UV protection.

The TPO material is a thermoplastic polyolefin (TPO) laminate designed to be installed on an existing roof. It comes in three layers:

TPO was initially used as a swimming pool coating before being applied to roofs. It is continuously researched for improvements. 

6 Key Benefits of TPO Roofing for Commercial Buildings

If you are renovating your existing building or building a new one, the advantages of TPO roofing are outstanding.


TPO is a highly durable material designed to endure the elements, traffic, heat, fire, and more.

It also is puncture and tear-resistant, which can be a common issue with other types of roofing while also withstanding thermal expansion and contraction of buildings.

Ease of Installation

TPO roofing is easy for our experienced roofers to install since it is made of lightweight material.

It doesn't require the same time-consuming metal roof construction, and therefore our roofing contractors will be able to start and finish your roofing job quickly.

The installation of TPO roofing uses the roll-on technique, which uses wide sheets of lightweight material rolled out over the sub-roof.

Heat welding the seams together forms a cohesive surface that keeps water out and prevents leaks.

TPO roofing is less expensive than other types of roofs because our contractors spend less time installing them.

Property managers and owners can save money by using TPO roofing since they typically don't pay as much for labor.


As a business owner, you understand the importance of the bottom line, so every penny saved counts.

Installation costs are reasonable—usually between $6 and $9 per square foot, including materials and labor.

Polyurethane, commonly known as EPDM, is a less expensive alternative at $5 to $8 per square foot for installation.

While TPO costs more to install, it has been shown to save building owners money over time by reducing your utility bill and repair expenses in the long run.

Energy Efficiency TPO roofs can save you up to 30% on energy costs due to their high heat reflectivity and Teflon coating that prevents the sun's rays from penetrating through into your building. TPO also has a low emissivity rating, which reduces solar radiation exposure by as much as 80%.

Energy Efficiency

TPO is one of the most energy-efficient flat roofing systems available on the market today.

Due to exceptional heat reflectivity, TPO roofs may help reduce your annual cooling costs by $16 per 1000 square feet.

Your building will not require as much cooling during the hotter temperatures because TPO reflects UV rays and therefore also reflects the heat.

In fact, white-colored TPO exceeds the EPA's ENERGY STAR requirements.

Versatility in Design Aesthetics

The color of PFPO roofing ranges from gray, white, black, and brown. The range of hues can complement your building's aesthetic if you choose.

It is important to remember that the roof does not have to be unattractive or one-color-fits-all to be energy efficient and high-quality.

Minimal Roof Maintenance

TPO has the advantage of requiring less upkeep.

It does not allow the accumulation of dirt and debris and is mold-resistant, puncture-resistant, tear-resistant.

TPO roofs are made of a flexible substance that allows them to move and settle.

This absence can cause cracks and gaps to form, causing leaks and potential water and structure damage.

It seals the roof and prevents moisture penetration between the top of the roof and the sub-roof by covering holes or gaps in the frame and sub-roof.

Because of its water resistance, TPO is therefore also resistant to algae and mildew. This means you will not need to have your roof frequently scrubbed clean.

Why You Need Professional TPO Roofing Installation

The roofing system you choose will have its own set of problems.

TPO roofs are still being tested for some of the issues they've encountered, as they're only a few decades old, and they are continuously being improved upon. 

However, there are some reasons why professional roofing installation is required with TPO:


A product can be perfect, but improper installation can compromise the integrity of the product. This is why it is essential to use one of our experienced roofers familiar with TPO roofing.

Vulnerability at the Seams

The technique for installing a TPO roof leaves seams vulnerable.

Because of the building's thermal expansion and contraction, the welds that hold the rolls of the TPO roofing membrane together can weaken and eventually separate. 

Once the seams disconnect, the roof is at risk of water damage and leaks. However, MM Dynamic can provide an annual inspection to ensure that any issues that might arise with the TPO roofing are caught before they become a huge (and expensive) issue.

Age of the Product 

Since TPO roofing has been in use for less time than other materials, it is essential to remember that it is not as widely used.

However, TPO is still a reliable product that has been tested and researched by various roofing companies.

TPO is a new solution for commercial buildings, but it benefits from being environmentally friendly and offering long-term savings to commercial building owners and property managers.
