Spring Cleaning Tips for Your Commercial Roof

Spring is officially here, which means it’s time for opening the windows and enjoying some warm weather. It also means it’s time for some Spring cleaning. Most people associate Spring cleaning with their homes and the interior of their properties, but it also applies to your commercial property’s roof as well. Performing maintenance on your property’s roof to welcome in the new season can increase its lifespan and potentially save you from surprise repairs throughout the year.

Commercial Roof Cleaning and Maintenance

Here are a few maintenance tasks you can work with your commercial roofing contractor to perform:

Schedule an Inspection

While inspections can and should be scheduled year-round, the beginning of Spring is one of the most crucial times to do so.  The freeze/thaw cycle of winter weather can do serious damage to your roof, causing leaks that lead to structural damages and insulation failure. With Spring generally signaling the end of this weather, it is best to schedule an inspection to evaluate the status of your commercial property’s roof going into the warmer months. Additionally, Spring’s climate conditions allow for thermal imaging inspections to be performed, which can catch early-stage leaks the naked eye cannot. Failure to schedule an inspection can lead to climate control issues in your building from faulty insulation or potential leaks and other damages from rain.

Cleaning Your Commercial Roof’s Surface

While it may seem pointless due to its constant exposure to the elements, having your roof’s surface cleaned can prove to be very beneficial, especially if you have a flat surface roof. Removing natural debris build-up from the winter as well as power-washing the surface can help prevent the building up of dirt and other grime. This build-up can lead to mold growth, which can cause rot in your roof’s key support structures.

Maintain Nearby Trees

If your commercial property is surrounded by trees or if you have trees on your property that hang over the roof, early Spring is the perfect time to trim and properly maintain them. While the Spring often brings enjoyable weather, it can also bring severe thunderstorms with hazardous conditions. Trimming any overhanging trees can prevent branches from breaking off onto your roof and causing major damages.

Clean Gutter Systems

Winters are known to accumulate large amounts of loose debris throughout a rooftop, leading to gutters becoming filled and clogged with leaves, sticks, moss, etc. When the spring rain comes, the gutters can quickly overflow and cause significant structural damage throughout the rooftop, meaning very costly repairs that could be avoided simply by cleaning out the gutters.

Spring cleaning maintenance on your commercial property’s roof may not seem necessary, but doing so can prevent headaches during what is otherwise one of the most enjoyable times of the year. Getting your roof inspected and cleaned, as well as removing any potential hazards on or around your roof, can help keep extend your commercial roof’s lifecycle and prevent costly repairs.

Why Get A Thermal Roofing Inspection For Your Commercial Building

Why Get A Thermal Roofing Inspection For Your Commercial Building

Why get a thermal roofing inspection for your commercial building? A quality commercial roof inspection is invaluable. Catching leaks and other damages in the early stages can save you a ton of money in repairs and prevent any massive surprise expenses. For this reason, our inspectors are trained to be as thorough as possible during these inspections. However, even the best inspectors can miss things that the naked eye can’t catch, which is why we utilize thermal imaging to make sure nothing goes unnoticed.

How Thermal Imaging Works

Thermal imaging is capturing an image of an object that allows you to see its heat radiating off of it via colors assigned to the level of heat. These colors are typically displayed using a yellow to red spectrum indicating heat and a green to purple spectrum indicating cooler temperatures. There are several ways that this is implemented when conducting a commercial roof inspection.

Identifying Leaks

When your roof leaks, the insulation begins to get saturated by the intruding moisture. Wet roofing insulation soaks up more heat throughout the day releases that heat slowly during the night. The longer this goes on, the more heat this section of your roof will maintain. Unfortunately, many leaks do not have any visual indicators until major damage has been done to the insulation and foundation of the roof. However, if a thermal imaging inspection is done, this spot on your roof will stand out due to the heat it is retaining.

The ability to do this is essential for protecting your commercial roof both in the short and long term. Making thermal imaging inspections part of your inspection cycle allows us to identify moisture infiltration spots and address them immediately. It also allows your project manager to map out potential problem areas on your property’s roof to keep a close eye on throughout your roof’s life cycle.

Conditions for a Thermal Roofing Inspection For Your Commercial Building

Due to the technology’s dependence on varying temperatures for proper identification of “hotspots”, certain climate conditions must be met to properly conduct a thermal imaging inspection. Our project managers advise only conducting these inspections when temperatures are 50 degrees F or higher. This is due to the fact that your property’s roof will likely absorb enough heat to create varying temperatures in areas where there are leaks. Additionally, we do not recommend performing a thermal imaging inspection after recent rain, as it will make it difficult to differentiate moisture from the rainfall and retained moisture from a leak.

Demonstrating Product Effectiveness

Another way A-Line Contractors implements our thermal imaging technology is to both demonstrate the effects and observe the condition of cool roof coatings. Cool roof coatings, such as Castagra’s Ecodur coating, are becoming increasingly popular as a green roof solution due to their sustainability, waterproof sealing, and UV reflective properties. These UV reflective properties significantly cut down on the amount of heat your roof absorbs, thusly lowering the energy costs associated with keeping it cool. To demonstrate this, we will often show property owners a before and after of the heat, their roof is radiating after applying the coating.

All property owners can benefit from a thermal imaging inspection being performed on their commercial property’s roof. It can help establish a baseline thermal signature that allows our project managers to create a customized long-term maintenance plan that can target potential problem areas that may be at risk for leaks in the future. Performing these inspections regularly also allows us to identify leaks in their early stages before the interior of your property becomes collateral damage.

Commercial Roof Damage. What Is Important To Know!

A good commercial roof remains out of mind until an issue arises. It is common for these issues to occur during inclement weather when your roof is left to bear the brunt of the elements. The reality is that even a well-maintained roof has its thresholds of what it can take in the event of a storm.

Are you concerned about commercial roof damage?

Here are four types of damages you may see on your commercial property’s roof:


Ponding is an accumulation of water that settles on the roof for more than 48 hours without draining or evaporating. This may seem harmless but can cause severe damage to your property’s roof. When left unchecked, this standing water can rapidly erode your roof’s membrane, which can cause leaks and sagging. Once your roof has begun to sag, ponding water will accumulate in greater quantities, which can lead to a total collapse of your roof once its weight threshold is exceeded.

Hail Damage

Hailstorms are no stranger to the Front Range area and can prove to be a severe threat to your roof’s integrity. Intense storms can dent or puncture your roof’s membrane, which can lead to ponding or leaking, depending on the severity of the puncture. Additionally, the bottom of your roofing membrane can shatter without any visible damage to the surface layer. This can lead to leaks going undetected, causing substantial damage to your roof’s integrity.

Ice Damage

During the winter months, your commercial property’s roof withstands what is known as a freeze-thaw cycle. While this may seem harmless, this cycle can lead to severe cracking and leaking in your roof’s membrane. If there is even the slightest opening in the roof’s surface, water from melted snow can seep into it and then re-freeze overnight. This causes the openings to expand and further crack, leading to more and more water seeping through your roof’s membrane, causing leaks and failures in the roof’s integrity.

Wind Damage

While commercial roofs are designed to withstand high winds, several factors can lead to your roof being compromised. Winds hitting extreme speeds can damage any roof, regardless of the material. The push and pull from high winds can lift, and eventually tear your roof’s flashing and membrane. In worst-case scenarios, pieces of your roof’s surface can tear off and damage other parts of the roof as the wind carries the debris.

Whenever a storm occurs, there is always a potential for your commercial property’s roof to be damaged. If these damages are caught quickly, the scale and the related repair costs can be mitigated. This is why A-Line Contractors highly recommends scheduling an inspection after any major storm.

Is It Time to Replace Your Commercial Property’s Roof?

We’ve all heard the adage “nothing lasts forever,” unfortunately, your commercial property’s roof is no exception. The reality is even well-maintained commercial roofing systems will eventually have to be replaced. That being said, when the time comes, there are some tell-tale signs your commercial roofing contractor can identify to minimize the costs of a failing roof.

Here are four signs to help you know “is it time to replace your commercial property’s roof?


The first and arguably most urgent sign that it is time to replace your commercial property’s roof is widespread leaking. When inspecting your property’s upper level, you may see watermarks or even warping on both the ceiling and upper walls. This is a sign that the membrane of your roof has begun to fail, and water is leaking into the building. Insulation failing due to the moisture it absorbed, warping of the ceiling and walls, and worst-case scenario, a total collapse of the roof due to its failing integrity are possible problems leaking can cause.

Membrane Damage

Your roof is one of your first lines of defense against the elements, especially against harsh weather conditions such as high winds and severe winter weather. When these occur, it can take a toll on your commercial property’s surface integrity, including uplifting, cracking, or tearing a significant amount of your roof’s membrane. If damage exceeds 30% of the roof’s surface, a total roof replacement should be considered, as extensive surface area damages can cause significant damage to the upper levels of your property if left unchecked.

Roof Rot

While we don’t often experience high volumes of rain in the front range, the fluctuation of snow to warm weather can lead to significant pooling or standing water on your property’s roof. Even when diligently addressed, continued exposure to this can lead to roof rot in the membrane. Roof rot can be identified by sagging spots, bubbling, discoloration, and water stains in the membrane of your roof. If caught early enough, this can be repaired; however, this rot could spread throughout your roof if allowed to decay, significantly compromising its integrity. This can be extremely hazardous if allowed to become widespread and would require an urgent roof replacement.

Insulation Failure

Noticing that your building isn’t maintaining a consistent temperature or that your energy bills are significantly increasing could be a sign that the insulation of your commercial property’s roof has begun to fail. When moisture begins to leak into your property, the first thing likely exposed to it is the insulation sitting below the roof. Water-logged insulation loses its effectiveness and will no longer maintain the internal temperature of your property. If left unchecked, moisture in the insulation can cause structural damage to the surfaces around it.

While roof replacement is inevitable in the long run, there are steps you can take to make sure that you don’t have to replace it earlier than necessary. One of these key steps is to schedule routine inspections and maintenance on your commercial property’s roof. Our team is trained to catch these problems using state-of-the-art technology and allows us to repair them for you before they significantly increase in scale.
