Reasons to Tend to your Roof Before Fall | Commercial Roof Maintenance

Prioritize Commercial Roof Maintenance, Repair or Replacement Before Fall

As summer winds down and fall begins its slow ascent, commercial roofs may face new challenges from changing weather patterns. Now is an opportune time to assess, maintain, repair, or even replace your commercial roof before unpredictable conditions take over; read on for five solid reasons for getting this process underway before autumn sets in. If professional assistance with commercial roofing needs is what you require, please visit

1. Weather Preparation:
Fall can bring heavy precipitation and fluctuating temperature patterns. A roof in good condition will help ensure your building’s interior stays dry during heavy rainstorms or early snowfall. Scheduling repairs or replacements in advance is the key to protecting against unexpected moisture-related damages for your business.

2. Energy Efficiency:
A properly maintained roof plays a crucial role in energy efficiency. As temperatures decrease and heating costs tend to increase, taking proactive measures such as insulation replacement, sealing gaps or fixing any damages can increase your building’s energy efficiency and lower utility bills over time.

3. Preventing Further Damage:
Minor roof issues left unaddressed during the summer can turn into bigger issues in fall due to changing weather conditions, such as moisture infiltration, small leaks or damaged shingles deteriorating further. Addressing such problems early prevents them from developing into more extensive and costly issues later.

4. Optimal Installation Conditions:
If your commercial roof requires replacement, fall is a great time to do it. Milder temperatures and lower humidity levels provide ideal conditions for installation or replacement work. By taking advantage of this season, you can minimize disruption to business operations while guaranteeing a strong and properly installed new roof.

5. Avoid Winter Emergency Roof Repairs:
Weather can be unpredictable, making emergency roof repairs more complex and more expensive during the colder months. By taking steps before fall arrives to address potential issues early, fewer sudden roof failures should occur during the winter, helping ensure business continuity and limiting unexpected expenses.

In preparation for fall’s arrival, it is critical that commercial roof maintenance needs are addressed as soon as possible. From weather readiness and energy efficiency savings to preventing further damage and optimal installation conditions – taking action early offers numerous advantages. Whether you’re in need of repairs or considering replacement options – contact Great Lakes Roofing’s professionals now by visiting to explore all available solutions and make sure your commercial roof can withstand its  next season without incident!

Understanding Summer Storms and Protecting Commercial Flat Roofs

With the arrival of summer, come the dangers, such as summer storms. These natural phenomena are not only breathtaking to watch, but they can also be dangerous to commercial flat roofs. Businesses must be aware of the damage that summer storms may cause to ensure their roofing system’s longevity and durability. This blog will explore the different threats that summer storms can pose to flat commercial roofs and the preventive measures to minimize the damage.

Heavy Rainfall

Summer storms can bring heavy rainfall that can overwhelm drainage systems, causing water to pool on flat roofs. Standing water on a roof can cause leaks, damage to roofing materials, and structural problems. Regular maintenance and inspections, such as clearing drainage systems, can help to prevent water accumulation and protect against issues related to water.

High Winds 

Strong winds are often a feature of summer storms, and they can cause havoc to commercial flat roofs. Strong gusts of wind can cause roofing materials to be lifted and displaced, especially if the roof is not secured properly. Damaged or loose components can expose the layers below, causing leaks and additional damage. Regular roof inspections will strengthen the roof by identifying and repairing any loose or compromised sections.

Hail and Flying debris

Summer storms can also bring hail or flying debris. Both elements can cause significant damage to flat commercial roofs. Hailstones may dent or puncture roof materials, which compromises their protective properties. Debris, such as airborne or tree branch debris, can also cause roof abrasions and tears. Installing impact-resistant roofing materials and performing post-storm assessments to identify any damage and correct it promptly can help protect against hail and debris-related harm.

Thunderstorms are often associated with summer weather patterns and increase the risk of lightning. Although flat roofs are not attracted to lightning, a lightning strike that is either nearby or direct can be dangerous. Damage to electrical systems, such as rooftop equipment, could lead to system failure or fire hazards. Lightning protection systems, grounding methods, and regular inspections of electrical systems can reduce the risk associated with lightning.

Commercial flat roofs need to be protected from summer storms. This is an important aspect of maintaining your property. Businesses can strengthen their roofing systems by taking proactive measures. To ensure that commercial flat roofs are durable, safe, and long-lasting, regular inspections, maintenance, and repairs must be performed. Businesses can minimize disruptions and weather storms by investing in prevention strategies.

We encourage you to reach out to us to schedule twice-per-year inspections for your commercial roof!

When flat roofs reach the end of their life-cycle

There are several reasons why a flat single ply roof can fail. Some common causes of failure include:

  1. Poor installation: A flat single ply roof must be installed correctly to ensure it performs as intended. If it is not installed properly, it can lead to issues such as leaks and premature deterioration.
  2. Weathering: Exposure to the elements such as UV rays, extreme temperatures, and moisture can cause single ply roofing materials to break down and deteriorate over time.
  3. Punctures or tears: Single ply roofing can be punctured or torn by sharp objects, such as tree branches or debris, which can compromise the integrity of the roof.
  4. Poor drainage: Flat roofs must be designed with proper drainage to ensure water does not pool or collect on the surface. If water is not properly drained, it can cause leaks and other damage to the roof.
  5. Aging: As with any roofing material, single ply roofs will eventually age and deteriorate over time, which can lead to failure.

To prevent failure, it is important to have regular maintenance and inspections of your flat single ply roof. Additionally, proper installation, design, and materials selection are critical in ensuring a long-lasting and effective roofing system. Great Lakes Roofing and Insulation can help you.

Hail! Hail! Go away hail!

Weather of any kind can be a threat to your commercial facility. Tornados, hurricanes, and other high wind, snow, and even light rain – if there are flaws in your roof membrane – can cause problems. Aside from an extreme wind event, perhaps no weather force is potentially more damaging than hail.

Storms that produce large hail get all the press (NOAA’s record is an 8-incher that fell in South Dakota in 2010), but not all the billions of dollars of annual hail damage are the result of press-worthy hail. Weather forensics company Dynamic Weather Solutions claims that hail smaller than an inch in diameter can break windows, scrape paint, and even kill chickens and other small birds.

So where does that leave your commercial roof? Hailstones an inch or more in diameter can cause obvious damage to your roof system that needs to be addressed as soon as possible. But even smaller stones can create less visible membrane cracks as well as damage the surface of underlying insulation. Both effects can shorten the lifespan of your commercial roofing system. The impact of hail can also loosen drainage systems around the perimeter of your building; after a storm, make sure those components are still fastened securely.

It’s critical that your commercial roof system continue to protect your facility as weather and seasons change. If recent hailstorms or other weather events have left your roof vulnerable or accelerated its aging, it’s time to consider repair or replacement options.

When looking for a replacement roof, consider one from a manufacturer that offers a warranty that covers hail damage. Such a warranty will probably be available for an extra cost, plus require that the new roof assembly include a thicker membrane and a rigid cover board underneath the membrane. However, the additional investment could be a good one if your commercial building is in an area where hail, is a common occurrence.

The commercial roofing experts at Great Lakes Roofing & Insulation are standing by and ready to offer roofing solutions, whether it’s investigating and repairing a leak problem or helping you plan for a replacement. We invite you to schedule a consultation with us right away.

Environmental Considerations for Commercial Roofs

In recent years, the commercial roofing industry has been trending toward lightweight, reflective materials. This shift has been environmentally beneficial in a couple of obvious ways: 1) lightweight means that less fuel is necessary to transport materials to the job site; 2) reflective means that the roof can deliver summertime energy savings to commercial facilities by reducing HVAC loads.

These roofing systems, primarily thermoplastic varieties like PVC and TPO, bring other environmental and business benefits as well. For example, in facilities that are not air-conditioned, reflective roofing can reduce interior temperatures because less heat is transferred into the building. Studies have shown that workers are more productive in environments that are even moderately cooler.

The observance of urban heat islands (UHI) has been an environmental topic for several years. A UHI is a tendency for cities – even small ones – to be several degrees warmer than the surrounding countryside. This is because roofs, streets and other “city” materials absorb and retain heat, creating conditions ideal for smog to form, which is a cause of respiratory health problems. Reflective roofing systems offer a benefit in this area because they don’t retain heat and can help reduce the UHI effect.

The insulation under your roof membrane is critical for keeping your building cool in the summer and warm in the winter. You may find it interesting that studies indicate that extremely high temperatures lower the R-value of most types of roof insulation and shorten the lifespan of its effectiveness. Cool, reflective roof materials reduce the amount of heat that penetrates, helping maintain insulation R-value and preserving your investment in insulation.

When it comes to roofing systems, PVC membranes have a smaller carbon footprint than others on the market, such as TPO, EPDM, built-up roofing, or modified bitumen: about 44% carbon content, compared with the others, which are close to 100%.

The primary function of any commercial roofing system is to protect the building from the elements. Once that’s met, there are a host of other reasons why some products are better environmental choices. Please contact Great Lake Roofing & Insulation to learn about all your options.

Get a Load of This: Snow on Your Commercial Roof

It’s bound to happen: a seasonal news story – or many – about a commercial roof collapsing because of the weight of several inches of recently fallen snow. The collapse isn’t the result of a failure of the roof, but the structure beneath it that couldn’t hold up to the additional weight of the snow. It may seem insignificant, but a square foot of heavy snow six inches deep can weigh 10 pounds. For just a small 1000-square-foot roof, that’s five tons of extra weight. Most flat commercial roofs are, of course much larger than that, and if yours is aging with weak areas, heavy wet snow could be a recipe for disaster.

If you have accumulated snow on your commercial roof, it might be a good idea to get up on it (safely – more about that below) and clear some or all of it away.

With respect to appropriate tools, a snow rake is better than a shovel, because it’s less likely to damage the surface. If shovels are all you have, make sure they have plastic (not metal) edges, and leave a couple of inches of snow on the roof.  Scraping it to the surface could damage the roof membrane.

Also make sure that drains, gutters, and downspouts are clear. Over the course of a winter, your roof is likely to undergo multiple freeze-and-thaw cycles, and snowmelt needs a place to go. If your drainage system can’t handle it, you’re likely to get layers of ice building up on your roof – and that can be even heavier and more dangerous than snow.

During your rooftop snow removal operation, practice good safety behavior. This means being extra cautious around the roof’s perimeter and near skylights. An inherently unsafe situation in clear, dry weather becomes downright hazardous in snowy, windy, wintry conditions.

If you’re not comfortable taking care of this yourself, hire a professional. Contact Great Lakes Roofing to discuss our full range of commercial roofing services. We look forward to hearing from you!

A Few Fun Commercial Roofing Facts

Your roof is an awesome component of your commercial building – providing watertight protection, season after season for (hopefully) 15 years or more. Here are a few tidbits of information about commercial roofing that you might find interesting.

Your flat commercial roof isn’t exactly flat. At least, you should hope that it isn’t. All roofs require slope and drainage to prevent water from collecting on the rooftop, which can promote mold growth, increase the likelihood of leaks, and eventually create structural damage. Over time, roofs can sag for a variety of reasons, and water will stop flowing toward edge gutters or central drains. A commercial roofer can possibly correct this problem by installing “crickets,” which are triangular structures placed on the surface to re-add drainage slope to the roof.

Your roof system could help lower your energy bills. Much like a white car is cooler to the touch than a dark one on a hot summer day, a reflective roof remains cool by reflecting solar energy. This reduces the amount of heat transferred into the building, lessening your HVAC load and corresponding utility bills. If you’re in the market for a new commercial roofing system, pick one that can deliver energy savings as well as long-term weather protection.

Different roofs have advantages in different settings. There’s a common belief that all commercial roofing systems are pretty much the same, but that’s not the case. New commercial buildings are commonly constructed with exposed metal roof decks because they’re cheap to install, durable and require minimal maintenance. EPDM membranes are relatively inexpensive to install and have low repair costs. Single-ply PVC systems are both highly reflective and excellent choices for manufacturing facilities because they’re resistant to a fire and a variety of industrial chemicals. Spray-on coatings can help lengthen the life of a deteriorating roof.

Your commercial roof deserves professional attention. Unless you employ a full-time professional roofing crew, Installation, maintenance, and repairs to your system are best left to a commercial roofer. A contractor has the know-how and tools to diagnose and address any problems with your current roof, and, when the time comes, propose a new system that will work well on your building.

At Great Lakes Roofing and Insulation, we look forward to working with you on your next roofing or insulation project. Please contact us if we can be of service. Our service areas include all of the upper peninsula of Michigan.
