Johnson Exteriors far exceeded our expectations. In short, my insurance was being difficult throughout the process of a roof replacement, yet Bryan and his team took care of all the work on the back end and I rarely had to handle any of it. Bryan's team was timely, kind, and there for me whenever I had a question. I would hands down recommend Johnson Exteriors for any exterior needs you might have.

Johnson Exteriors was great to work with during an insurance claim for a new roof. From the initial estimate all of the way through the installation of the new roof until the final check was received from the insurance company. They explained everything and made sure we understood what work they were doing and not doing and helped coordinate any adjustments needed with the insurance company. They also had someone on site the entire day of the installation available if we had any questions. They cleaned up after the install and were back within a couple of days to pick up any extra supplies. I would definitely reach out to Johnson Exteriors for any future exterior needs.

When winter rolls in, businesses with commercial flat roofs often face an uphill battle with Mother Nature. Accumulation of snow on these surfaces can lead to significant damage and costly repairs if not effectively addressed. This article offers a comprehensive guide on how to remove snow from your commercial flat roof.
Snow removal from a flat roof is not just about aesthetics or reducing the weight bearing down on the structure. It also has a lot to do with preventing moisture infiltration, ice dams, and blocked drainage systems – all of which can severely damage your roofing system.
There are several innovative methods business owners can utilize for efficient commercial flat roof snow removal:
Always remember, safety should be a paramount concern when removing snow from your commercial flat roof. Use proper gear, use appropriate tools and consider hiring professionals if necessary.
The optimal time for removing excess snow off your flat roof depends on several factors:
Follow this five-step process for effective commercial flat roof snow clearance:
Step 1: Assess the situation – Before starting any work, measure the depth of the accumulated snow and visually inspect for any damages.
Step 2: Prepare your tools – Have all necessary tools at hand including sturdy ladders, long-handled rakes or blower machines depending on what seems best fit.
Step 3: Start clearing – Begin clearing in sections starting near drains to facilitate melting water flow off your roof.
Step 4: Watch out for equipment – Avoid damaging antennas, solar panels or other equipment mounted on your rooftop while clearing out the snow.
Step 5: Consider professional help – If it proves too challenging or dangerous, consider hiring professional help to ensure efficient and safe removal.
By effectively managing snow removal from your commercial flat roof, you can prevent potential damage and maintain the integrity of your building structure throughout the winter season.
With the arrival of winter, snow becomes a common sight in many regions. This can pose a significant challenge to commercial buildings with flat roofs. While the beautiful layer of white fluff might seem harmless, it can cause serious damage to your commercial flat roof structure if not dealt with promptly. Here, we delve into the importance and necessity of snow removal for your flat roof structure.
One primary concern with accumulated snow is the added weight on your roof. Flat roofs are particularly susceptible to this due to their design. A cubic foot of dry snow weighs about 7 pounds, while the same amount of wet snow can weigh up to 20 pounds. A heavy load of wet snow can cause severe structural damage or even a roof collapse if not removed in time.
Another issue is the potential for ice dams. When heat from inside your building melts some of the accumulated snow on your roof, it refreezes near the edges creating what is known as an ice dam. These ice dams trap water on your roof which over time will find its way into cracks or seams in your roofing material leading to leaks and water damage inside your building.
Moreover, prolonged exposure to freezing temperatures and moisture can deteriorate roofing materials rapidly leading to higher maintenance costs or even necessitating a full roof replacement earlier than expected.
Here are some reasons why regular and efficient snow removal is necessary:
Let’s not forget about the safety aspect. Accumulated snow could fall onto pedestrians or vehicles, leading to accidents and potential lawsuits. It is important for businesses to take proactive steps in maintaining safe premises during winter months.
As we have discussed, the necessity of removing snow from your commercial flat roof structure cannot be overstated. Failure to do so can lead to a host of problems that can seriously impact your commercial building’s integrity, safety, and overall lifespan. Regular and efficient snow removal is a necessary part of maintaining your building’s health during the winter months.
Commercial flat roofs are particularly susceptible to the accumulation of snow during the winter season. Due to their horizontal design, they don’t have the benefit of a slope to naturally move snow off. This can lead to heavy loads of snow that can potentially damage the structure and create dangerous conditions. Hence, it’s important to explore efficient ways for commercial flat roof snow removal. Here are some innovative ideas and practices.
Heated cables are an effective tool for minimizing ice buildup and facilitating easier snow removal. These specialized cables can be installed in areas that often experience heavy ice buildups, such as roof edges, drains or gutters.
Snow guards are devices that can be installed on flat roofs to prevent large amounts of snow from suddenly sliding off. They help manage how the snow comes down from your roof by breaking it up into smaller amounts.
A long-handled rake can help remove accumulated snow while maintaining safety. It’s important to use one made specifically for roofs to avoid damaging the roofing material.
Professional services specialize in removing heavy loads of snow quickly and safely using specialized equipment. They understand how to navigate the unique challenges that flat commercial roofs present.
Calcium chloride can be used to melt the snow, turning it into a slushy consistency that is easier to remove. It’s important to use it sparingly and only when necessary as it can potentially cause damage to certain roofing materials.
Taking the time to consider these innovative methods for commercial flat roof snow removal can effectively reduce the risk of roof damage and promote safety during the winter season. But always remember that every situation is unique. Therefore, it’s essential to tailor these methods according to your roof’s specific needs and conditions.
As a commercial building owner or manager, dealing with snow buildup on your flat roof is a critical part of winter maintenance. This task should be performed timely and properly to avoid damage to your property and maintain a safe environment. But, when exactly is the best time to remove excess snow from your commercial roof? The answer varies depending on certain factors, including local weather patterns and the structure of the building itself.
Weather patterns play a significant role in determining snow removal times. Monitor weather forecasts during winter months for heavy snowfall warnings that could lead to excessive accumulation on your flat roof.
Different roofing materials possess varying load capacities. Understanding how much weight your commercial flat roof can handle helps you decide when it’s time for a clean-up.
Freeze-thaw cycles can cause significant problems for flat roofs. When accumulated water freezes, it expands, creating pressure and potential damage, especially when this cycle repeats.
While maintaining vigilance about weather patterns and understanding your roof’s load capacity is essential, hiring professional services ensures efficient and safe removal of surplus snow. These experts possess specialized equipment necessary for quick and effective cleaning without damaging the roofing material.
Identifying the optimal time for removing excess snow from your commercial flat roof involves careful consideration of many factors. By keeping an eye on weather forecasts, understanding load capacities, anticipating freeze-thaw cycles, and engaging professional services when needed are among some strategies that could help prevent potential damages caused by excessive snow buildup on roofs during winters.## Detailed Five-Step Process for Effective Commercial Flat Roof Snow Removal
Snow removal from a commercial flat roof is a considerably important task that needs to be performed with utmost care and precision. A five-step process can aid in this job, ensuring an efficient and effective operation while also preventing potential damage to the roof. Here are the detailed steps:
The first step towards effective snow removal is a thorough assessment of the situation. Examine the amount of snow accumulated on your flat roof and determine if it poses any potential risk.
During your assessment, keep an eye out for:
After assessing your roof’s condition, gather all necessary tools and equipment for snow removal. This may include:
Begin your snow removal process by clearing the drainage areas first. This aids in preventing water from pooling on your roof once you start removing the snow elsewhere.
Remember to clear any ice or debris that might be blocking these areas to ensure proper flow of melting snow.
Start removing snow from your flat roof in sections. Always work from top to bottom (from higher elevations down), pushing or pulling small amounts of snow at a time off the edge.
Remember – do not scoop all way down to roofing surface as this can lead to scratches or other damages. It is recommended leaving about half an inch of snow atop the roof surface.
After the snow has been cleared, continue to monitor your commercial flat roof regularly. Excess snow can accumulate quickly, especially during heavy snowfall seasons. Repeat the process as necessary to maintain a safe and functional roof structure.
By following this detailed five-step process, one can effectively remove snow from a commercial flat roof. Always remember to prioritize safety over speed of removals to avoid any accidents or potential damage to your property.
Common signs may include recurring leaks, missing or curling shingles, granule loss, storm damage, sagging roof areas, recurring ice dams, or roofing materials nearing the end of their lifespan.
Many homeowners choose architectural asphalt shingles, impact-resistant shingles, or residential metal roofing systems designed for severe weather exposure and long-term durability.
Ice dams are often caused by attic heat loss, ventilation deficiencies, uneven roof temperatures, and trapped attic moisture rather than snow accumulation alone.
Signs may include lifted shingles, missing shingles, granule loss, damaged flashing, leaks, gutter damage, or water staining inside the home following severe weather events.
